I manage purchasing for a mid-sized company — around 200 employees across two locations. I handle everything from office supplies to specialized components, which is how I ended up knee-deep in the world of TE Connectivity products and services. I’ve processed a lot of orders for connectors, sensors, relays — you name it. And I’ve made my share of mistakes.
Here’s the thing: I used to think a connector was a connector. Especially for internal prototype runs or test setups where the specs seemed straightforward. I’d find a cheaper alternative, save a few bucks per unit, and think I’d done my job. But I’ve learned the hard way that the real cost of a poor-quality component isn’t on the invoice. It’s in how it makes your team — and your company — look.
What I Used to Think Was the Problem
My first few years in this role, I thought the main issue with buying components was simple: find the best price, check the specs, place the order. If the specs matched, we were good, right? Wrong.
I remember one project where an engineer needed a specific connector for a prototype. He specified a TE connectivity part number, and I found a direct alternative from another manufacturer. The spec sheet looked identical. Same pin count, same current rating, same footprint. I felt pretty good about saving us about $50 on a small batch order.
Then the prototype failed during testing. The connection was intermittent. The engineer spent a week troubleshooting, only to trace it back to the connector. The plastic housing had slight dimensional inconsistencies, causing the pins to lose contact under vibration. We ended up ordering the original TE part, plus a week of lost engineering time — which, if I’d calculated our internal cost correctly, was easily $1,500.
That’s when I started paying attention to what “quality” actually means in this space.
The Real Cost: It’s Not Just About Rework
So sure, rework costs time and money. But I’ve come to realize that’s actually the small part of the problem. The bigger issue? How these failures affect the people who rely on our equipment.
Take our telecom testing rigs, for example. We use TE connectivity data center developer kits for some of our field-testing prototypes. These go to client sites. A connector failure in a lab is an annoyance. A connector failure in front of a client is an embarrassment.
I once heard about a situation from a colleague — an installation where a sensor package failed because of a relay that didn’t meet spec under temperature cycling. The field engineer had to go back, diagnose it, replace it, and reschedule the client’s deployment. The client didn’t see “defective relay.” They saw “unreliable system from Company X.”
To be fair, some of this is just the nature of working with electronic components. Nothing is 100% reliable. But when I see connectors from cheaper sources failing at noticeably higher rates, I think: is saving $10 per unit worth risking a client’s perception of our brand?
What Changed My Mind: The Data Center Experience
I really began to understand this after a project where we were setting up a bunch of test stations for a data center proposal. The specification called for specific TE connectivity products and services — the connector systems, the cable assemblies, the works.
My initial reaction was: this is going to be expensive. I looked at alternatives. But the project lead (a senior engineer) explained something I hadn’t considered. He said: “The spec isn’t just about electrical performance. It’s about documented traceability, test data, and field-proven reliability. When we present this proposal, the client’s engineering team will audit our design. If we use components from a supplier they can’t verify, it raises questions about our whole approach.”
I only believed that after I saw it play out. The client’s team did audit our Bill of Materials. They asked about every major component. When the engineer could point to TE connectivity’s datasheets, application notes, and compliance certifications, the conversation moved fast. If we’d used a no-name equivalent, we’d have spent days defending the choice instead of talking about our solution.
There’s something satisfying about a project where the components aren’t the point of contention. After all the stress of proposals, deadlines, and design reviews, having a reliable supply chain that doesn’t create friction — that’s the payoff.
The Hidden Layer: How Components Affect Your Company’s Image
This is the part I don’t think most people in my role talk about enough, but it’s been my experience: the physical quality of what you deliver — whether it’s a prototype, a test rig, or a production unit — becomes a proxy for your company’s competence.
If a connector feels cheap, or a cable assembly has inconsistent molding, or a relay chatters when it switches — the person on the receiving end doesn’t think “we saved a few bucks.” They think “this company cuts corners.”
I’ve seen it happen. We had a vendor deliver a batch of sensors that looked identical to the premium ones but had a slightly different color temperature on the lens. It sounds trivial, but the client’s procurement manager noticed and asked if we’d switched suppliers. We hadn’t — it was a different batch from the same supplier — but the perception of inconsistency was already planted.
In my opinion, this is especially true in B2B. Your client’s engineers are looking at your components with a critical eye. If something looks off, they start questioning everything else. The $50 difference between a TE connectivity relay and a generic alternative might seem like a savings on paper, but if it costs you even one cycle of client skepticism, it’s not worth it.
Now, I’m not saying you should always pick the most expensive option. That’s not realistic. Budgets exist. But I’ve learned to think about it differently. The cost of a component isn’t just its price. It’s the price plus the expected cost of failure, the cost of engineering time to diagnose issues, and the cost of brand risk.
What I Do Now (and What I’d Suggest)
Okay, so the problem is clear: poor-quality components can cost more than they save, and they can damage your company’s reputation in ways that are hard to quantify but very real.
Here’s what I’ve actually changed in my approach. It’s not revolutionary, but it works for me.
1. I check the supplier’s track record for the specific component family. I don’t just look at the datasheet from the alternative. I check if the supplier has application notes, if the part has been used in similar applications, and if there’s field data. For TE connectivity, this is usually straightforward — they have extensive documentation. For others, sometimes you get a sheet and a “good luck.”
2. I factor in the cost of failure. Lost engineering time, rework materials, delayed project timelines, and client dissatisfaction. I try to calculate a “total cost of ownership” for critical components. Saving 20% on a $10 connector isn’t worth it if it has a higher failure rate that costs $500 in troubleshooting.
3. I trust the engineers’ specifications. If they specify a TE connectivity part for a reason — especially for prototype or field-test equipment — I don’t substitute without clearing it with them first. Because they know the operating conditions and the reliability requirements better than I do.
4. I look for consistency in secondary characteristics. Things like packaging, labeling, and the overall “fit and finish” of the components. If a supplier can’t get the packaging right, I worry about what else they’re not checking.
That said, I still buy alternative components for non-critical applications. For simple test bench setups where failure is not a big deal? Sure, I’ll take the budget option. But for anything that goes to a client, or is part of a field deployment, or uses a TE connectivity data center developer kit specification? I stick with what’s proven.
The way I see it, my job isn’t just to save money. It’s to make sure our internal clients — the engineers, the IT team, the field operations — have what they need to make our company look competent and reliable. And that means choosing components that do the job without drama.
