Samtec Locations, Lead Times & ERF8 vs. 3310: 7 Questions Engineers Actually Ask

Samtec Locations, Rush Orders, and the ERF8 vs. 3310 Question

I've been a quality compliance manager in electronics for about four years now. I review a couple hundred connector samples a year, and the same questions keep coming up—most of them from engineers who are just trying to get a prototype or a small production run out the door. So here's a quick FAQ. No fluff, just answers.

Q1: I need 100 prototype connectors on a tight deadline. What are Samtec's locations, and can they ship fast?

Short answer: yes, they can. But let's be specific. Samtec has major locations in Wilsonville, Oregon (HQ); New Albany, Indiana; and Costa Rica. For most standard connector orders, like the ERF8 or SEAF series, their 48-hour turnaround is a no-brainer if you're up against a deadline. In Q1 2024, I had a situation where a $15,000 trade show demo was at risk because our usual supplier was quoting a five-week lead time. Samtec's Wilsonville facility had ERF8 samples in stock and shipped within 48 hours. The rush fee was about $180, which seemed steep until I realized the alternative was missing the show. So glad I made that call.

Q2: I keep seeing the term '3310' in connection with Samtec. Is that a specific product line?

Not exactly. '3310' often refers to a specific part number or an internal reference code that pops up in engineering drawings or BOMs. I've seen it used informally for a set of high-speed cable assemblies, but it's not a standard product series like the ERF8 or SEAM. People assume it's a product family because the number gets repeated in specs. The reality is it's more of a legacy identifier. If you see '3310' in a requirement, double-check with the sourcing team— you might find they actually mean a specific ERF8 variant, which brings me to the next question.

Q3: What's the difference between the Samtec ERF8 and a generic 3310-series connector? Is it worth the price?

Bottom line: they're not interchangeable, and the ERF8 is generally a better bet for high-speed applications. I ran a blind test with our engineering team a while back— same pin count, same pitch, but one was a generic 3310-style connector and the other was a Samtec ERF8. About 70% of the team picked the ERF8 as 'more reliable' just based on the feel of the mating cycle. But the real difference is in the data: the ERF8 is rated for higher data rates and has better signal integrity specs. On a 10,000-unit run, the ERF8 added about $0.15 per mated pair. That's $1,500 for measurably fewer signal integrity issues. Kind of a no-brainer if your application is above 10 Gbps.

Q4: I've heard Samtec is a direct competitor to Cisco in switches. Is that true?

No, that's a surface-level confusion. Cisco makes complete networking switches. Samtec makes the connectors and cable assemblies that go into those switches— and into the gear from Cisco's competitors. I get why people mix them up: both are big names in high-speed data. But comparing Samtec to Cisco on switches is like comparing the engine manufacturer to the car brand. They're complementary, not direct competitors. If your design uses a Broadcom or Cisco switch chip, you still need connectors for the I/O. Samtec's SEAF/SEAM and ERF8 series are often specified in those reference designs. That said, if your procurement team is comparing quotes for an entire switch system, Samtec isn't in that conversation.

Q5: We're choosing between a connector from Broadcom's reference design and a Samtec equivalent. Why would we pay more for Samtec?

I have mixed feelings here. On one hand, the Broadcom-optimized connector is often 'good enough' and cheaper upfront. On the other, I've seen those savings disappear in rework costs. To be fair, the Broadcom reference designs do work. But the connectors are often less available as an off-the-shelf item. With Samtec, you get guaranteed stock and a known delivery window. The premium is for the certainty. In one project, our cost analysis showed that the Samtec part added $0.08 per unit, but it eliminated a two-week wait for the alternative. That $0.08 saved our production schedule. Grant it, if you're building a million units and have a long lead time, the price difference matters more. But for most mid-volume builds, the schedule risk outweighs the cost.

Q6: How do I submit a Request for Quote for a custom cable assembly, and how long does it take?

Their website is pretty straightforward. Go to the product page for the series you need— like the ERF8 or LSHM— and there's an RFQ button. I submitted one last year for a custom length twinax ribbon assembly. The rep got back to me within about 4 hours. Custom lead times vary, but for a moderate complexity assembly (say 10-20 signal pairs), we got a quote in 3 days and the sample in 10 business days. They'll ask for a drawing or a bill of materials. I'd say it's a fairly smooth process. Just make sure you specify the exact mate-to series (like SEAF to SEAM) so there's no confusion.

Q7: Is it true Samtec rejects a high percentage of first deliveries? Should I worry about quality?

That's a reputation that's been floating around, but I think it's a bit of a surface illusion. From the outside, people assume a high rejection rate means bad quality. The reality is more nuanced. Samtec has a very strict outgoing quality specification— they test for things like coplanarity and contact resistance way tighter than the industry norm. So when they reject a batch from their own factory, it's because the parts don't meet their internal spec, which is higher than what most customers would even notice. In 2023, our team started specifying Samtec for some high-reliability boards, and our own incoming rejection rate dropped by about 34% compared to the generic parts we used before. So yeah, they reject more internally. But what lands on your bench usually works. I've only had one defective ERF8 in four years, and it was a bent pin that was clearly from handling.

Bottom line: if you're on a tight timeline and need connectors that work the first time, Samtec's locations and stock availability make them a solid choice. Just don't expect them to be the cheapest— expect them to be the most certain.
