When you send us a bill of materials for an industrial control system, the first question we ask is not “what is the price?”. The first question is “what does this board need to do for the next ten years?”. That single question shapes every sourcing decision we make for you. We are Informic, and we work with manufacturing teams across Africa who build, repair, or upgrade control equipment. Our job is to turn a confusing list of part numbers into a clear, actionable quotation. This article explains exactly how we do that, and what you can expect from us.
Our Direct Answer on Sourcing
Electronic component sourcing for industrial control equipment is about matching three things: the functional requirement of your circuit, the environmental conditions of your factory floor, and the long-term availability of the part. We do not simply buy the cheapest part that fits the footprint. We buy the part that will still be available, and still perform, when your maintenance schedule calls for a spare in three years. A quotation from us is a statement of confidence in that match, not only a price list.

What We Mean by “Clearer” Purchasing
Procurement buyers in African manufacturing often face a specific set of problems. You might receive a datasheet in a language that does not match your internal documentation. You might find a distributor who shows stock, but cannot confirm the date code or the original manufacturer. You might get a quote that looks low, only to discover hidden costs for freight, customs clearance, or minimum order quantities.
We remove that noise. When you request a quotation from us, you receive a document that separates the cost of the component from the cost of getting it to your door. You see the manufacturer, the part number, the recommended alternate, and the estimated lead time. You also see our confidence level on that lead time, based on our current supplier conversations. We do not promise what we cannot verify.
Our Sourcing Process: Step by Step
We use a structured approach for every RFQ (request for quotation). This is not a formality; it is how we avoid costly mistakes. Here is the flow we follow with your team.
Step 1: BOM Review and Clarification
Send us your complete bill of materials, even if some lines are uncertain. We will review it for common issues: obsolete part numbers, insufficient voltage ratings, or components that are not rated for extended temperature ranges. We will ask you specific questions. For example, “This motor driver IC has a recommended heatsink pad. Does your enclosure allow for that?” or “This capacitor is rated for 105°C. Your ambient temperature is listed as 70°C. Is that peak or continuous?”. These questions are not delays; they are the process.
Step 2: Sourcing and Alternate Identification
Once the BOM is clear, we source against your approved manufacturer list. If a part is unavailable, we do not silently substitute. We present an alternate with a clear explanation of the difference. That explanation covers electrical specs, thermal performance, and mechanical fit. You decide, based on your engineering team’s comfort level. We never swap a part without your written approval.
Step 3: Quotation with Transparent Pricing
Our quotation includes the unit price, the currency, the Incoterms, and the estimated freight cost. We also show the price break for different quantities. For industrial control equipment, we often see that buying a slightly larger quantity of a critical IC saves you significant money per unit. We will point that out if it is true for your BOM. We will not inflate quantities to make our margin higher.
Step 4: DFM Feedback (Design for Manufacturability)
If you are still in the design phase, we offer DFM feedback as part of our sourcing service. This is where we look at your PCB layout and component choices for potential production issues. For example, we might note that a specific connector is only available in tape-and-reel, which is fine for automated assembly, but difficult for a small prototype run. Or we might suggest a different footprint for a resistor that allows for better solder paste flow. This feedback is practical and based on our daily work with pcbManufacturing partners.
This is a key point. Our sourcing service is directly connected to our knowledge of pcba assembly. We know what happens to a component when it goes through a reflow oven, and we know what happens when it is hand-soldered in a repair shop. That knowledge informs our sourcing recommendations.
Practical Table: What You Should Ask Your Supplier
To help you benchmark any supplier, including us, we have prepared a simple table of questions to ask before you commit to a quote.
| Question to Ask | Why It Matters | What a Clear Answer Looks Like |
|---|---|---|
| What is the exact manufacturer and part number? | Prevents counterfeit or ambiguous parts. | “STM32F103C8T6 from STMicroelectronics, not a generic clone.” |
| What is the component’s date code? | Older stock may have degraded solderability. | “Date code is 2024, stored in original reels.” |
| What is the confirmed lead time? | Production planning depends on this. | “12 weeks from order confirmation, shipped from our Singapore hub.” |
| What are the freight and customs terms? | Total landed cost, not only unit price. | “DDP Lagos, includes duty and handling, no surprise fees.” |
| What is the minimum order quantity (MOQ)? | Avoids overbuying for a small repair run. | “MOQ is 500 pieces, but we can split a reel for a 20% fee.” |
Why Industrial Control Needs a Different Sourcing Approach
Industrial control equipment is not consumer electronics. A smartphone is replaced every two or three years. A programmable logic controller (PLC) or a variable frequency drive (VFD) in a cement plant or a food processing line might run for fifteen years. The components inside those units must be robust. They must tolerate vibration, dust, humidity, and sometimes extreme heat. They must also be available for a long time, because your maintenance team cannot redesign a board every time a capacitor goes end-of-life.
We understand this because we work with components that are specifically selected for this environment. We look for industrial-grade temperature ratings (often -40°C to +85°C or wider). We look for components with a proven track record in similar applications. We avoid the latest consumer-grade parts that might have a short market life. This is a different mindset from a general-purpose electronics distributor.
The RFQ Process: What We Need From You
To give you a fast and accurate quote, we need a few things from your side. You do not need a perfect BOM, but you do need to be honest about what you know and what you do not know.
- Complete BOM: Include manufacturer part numbers if you have them. If not, include the value, package, and any markings you can read from the physical part.
- Target Quantity: Tell us the quantity you need to build now, and the quantity you might need in the next 12 months. This helps us negotiate better pricing.
- End Application: Tell us what the board does. Is it a motor controller? A temperature sensor interface? A safety relay? This helps us spot potential issues.
- Delivery Location: We need the final destination city and country to calculate freight accurately.
- Timeline: When do you need the parts? Is this a stock replenishment or an emergency repair?
With this information, we can usually provide a preliminary indication within 48 hours. A firm quotation with confirmed pricing and lead times takes longer, typically 3 to 5 business days, because we verify stock with our suppliers.
How We Handle Obsolete and Hard-to-Find Parts
This is a common pain point for industrial control teams. You have a 10-year-old machine, and a critical sensor driver chip is no longer made. We have two approaches. First, we search our network of authorized distributors and independent stockists for original, unused stock. We verify the authenticity of these parts through visual inspection and, where necessary, electrical testing. Second, we look for a form-fit-function replacement. This is not always possible, especially for complex digital ICs. But for analog components, passives, and some microcontrollers, a suitable replacement often exists. We present the option to you with clear data, and you make the final call.
Why We Focus on African Manufacturing Markets
We are not a global conglomerate with a generic website. We have chosen to focus on serving manufacturing teams in Africa because we understand the specific logistics and challenges. We know that freight to Lagos, Nairobi, Johannesburg, or Accra can vary significantly in cost and reliability. We know that customs clearance can be unpredictable. We build our lead times with this reality in mind. We do not quote a standard 5-day delivery if we know the shipping route typically takes 10 days. We also work with local logistics partners who can handle the final mile delivery to your factory, not only to a port.
This focus means we are more than a parts supplier. We are a partner in your production planning. We will tell you if a part is risky to source, even if we could make a sale by hiding that risk. That honesty is the foundation of our long-term relationships.
Practical Recommendations for Your Next Purchase
Here is what we suggest you do before you send your next RFQ, whether to us or to any other supplier.
- Clean your BOM: Remove any line items you are not sure about. A BOM with 200 lines where 20 are duplicates wastes everyone’s time.
- Check your own stock: Do you already have 500 of that resistor in your store? Do not ask us to quote it.
- Define your acceptance criteria: What is the minimum operating temperature? What is the allowable tolerance? Write it down.
- Ask for the alternate upfront: We always provide one when possible. You should expect this from any good supplier.
- Get a quote in writing: Verbal agreements are not useful for your accounting department. We always provide a formal quotation.
FAQ
How quickly can you provide a quotation for a standard BOM?
For a standard BOM with clear manufacturer part numbers and no obsolete parts, we can usually provide a preliminary quotation within 48 hours. This is based on our current supplier price lists. A firm quotation with confirmed stock and lead times typically takes 3 to 5 business days. If your BOM has obsolete or hard-to-find parts, we will inform you immediately and give you a realistic timeline for sourcing.
Do you guarantee that all components are original and from the original manufacturer?
We guarantee that all components we supply are sourced from authorized distributors or reputable independent stockists. We do not sell counterfeit parts. For every component, we can provide a certificate of conformance or a traceability report upon request. We also visually inspect each reel or tube before it is packed for shipment. If you require additional testing, such as X-ray inspection or electrical parameter verification, we can arrange that at an additional cost.
What is your policy on component substitutions or alternates?
We never substitute a component without your explicit written approval. When we identify a potential alternate, we provide a detailed comparison of the electrical characteristics, thermal ratings, and mechanical dimensions between the original and the proposed replacement. Your engineering team makes the final decision. We also document the approved alternate on the packing slip, so your receiving team knows exactly what to expect. This process prevents confusion on the factory floor.
