Samtec Connectors FAQ: From New Albany Headers to Common Ordering Pitfalls

Samtec Connectors FAQ: Real Answers from Someone Who's Been Burned

I've been handling Samtec connector orders for about six years now – mostly high-speed board-to-board stuff, rugged cable assemblies, and micro-pitch headers. Along the way I've made maybe $4,000 worth of avoidable mistakes (I keep a spreadsheet). So I put together this FAQ to answer the questions I wish someone had answered for me back in 2018.

1. Where is Samtec located? (New Albany, Indiana)

Samtec's global headquarters is in New Albany, Indiana – about 15 minutes from Louisville. I've never actually been there (I work remotely), but their customer support team is based there and they're surprisingly responsive. If you ever need to overnight a prototype, the shipping address is 520 Park East Blvd, New Albany, IN 47150. Just don't expect a tour; I tried once (that's a different story).

2. What exactly is a Samtec header?

A header is basically the male half of a board-to-board or wire-to-board connection – those rows of square pins you solder onto a PCB. Samtec makes about a gazillion variations: straight, right-angle, shrouded, unshrouded, with or without locking latches. The most common series I use are the TSW (standard .100" pitch) and the QSH (high-speed .050" pitch). Pro tip: never assume a header is compatible with a receptacle just because the pin count matches – the pitch can be off by 0.1mm and you'll waste a whole prototype run. (Ask me how I know. Actually, don't – it was a $320 mistake last year.)

3. Can I test a Samtec header with a multimeter? (Yes, and here's how)

Absolutely. I use a Fluke 117 multimeter (that's the one with the non-contact voltage detection – not strictly needed for continuity, but it's what I have). Set it to continuity mode, touch one probe to a header pin and the other to the corresponding solder pad on the board. If you hear the beep, you're good. But here's the gotcha: I've tested headers that beeped fine but still had intermittent failures later. Why? Because the pin wasn't fully seated in the plastic housing – the multimeter only checks electrical conductivity, not mechanical lock. So if you're getting a solid beep but the connection seems flaky, check the plastic retention. I learned this the hard way on a 50-piece order in 2022 – every single one passed continuity but three failed vibration testing.

4. What does "8110" mean in connector ordering? (And how it almost cost me $500)

I've seen engineers ask for "8110 connectors" and I've made that mistake myself. Here's the thing: 8110 is not a Samtec part number. It's either a competitor's number (like a TE or Amphenol housing) or an internal project code. One time in 2021, a customer sent me a BOM with "8110" next to a header. I assumed it was a Samtec ERF8 series with 110 positions? Nope. It was a completely different footprint. The order shipped, the parts didn't fit, and I had to eat the cost of both the connectors and the PCB re-spin – about $480 total. Now I have a rule: if I don't recognize a six-digit number, I ask for a datasheet before quoting. (Note to self: update our part number validation spreadsheet.)

5. How to unlock a phone using Samtec connectors? (Short answer: you don't)

Look, I've seen some weird search queries land on our site. “How to unlock a phone” has nothing to do with connectors – unless you're talking about physically opening the phone to replace a component. In that case, you might need a micro-pitch connector like the Samtec FSLP series that's used inside smartphones. But unlocking the software? No, that's a carrier thing. So if you landed here looking for phone unlocking tips, I'm sorry to disappoint. But if you're trying to open your phone to repair it, the pogo pins or board-to-board connectors inside might be Samtec. Check the part number, and feel free to reach out – I've helped a few hobbyists identify connectors from disassembled devices.

6. How to avoid the most common Samtec ordering mistake (before it costs you)

I've made this mistake three times before I finally automated a checklist. Here it is: before you place an order for a Samtec header, make sure you've verified three things:

• Pitch – .100", 2mm, .050"? They're all different widths. A 1.27mm pitch header won't fit a 2.0mm receptacle even if the pin count matches.
• Plating – Tin vs gold. Gold is for high-reliability and high-cycle applications. Tin is cheaper but corrodes faster. I once ordered tin-plated headers for a prototype that shipped to a humid environment – the pins tarnished within a month.
• Orientation – Straight vs right-angle. Sounds obvious, but when you're ordering in bulk, it's easy to miss. My worst blunder was a 200-piece order of right-angle headers when the PCB layout called for straight. $890 wasted, including the expedited shipping to get the correct ones in time.

Now I use a shared Google Sheet with dropdowns that enforce these checks. It's not fancy, but it's caught about 12 potential errors in the past 18 months. (That's probably saved us $2,000+ in rework and shipping.)

Prices and product availability as of May 2025 – verify current spec with Samtec's official site or your distributor. My experiences are based on roughly 200 orders, mostly mid-range volumes between 10 and 500 pieces. If you're ordering million-piece lots or working with ultra-miniature connectors, your mileage may differ.
