What are the key features of SEAM-50-03.5-S-06-2-A-K-TR?
- Gold (30 µin) over Nickel (50 µin) contact finish on mating interfaces for superior corrosion resistance and low contact resistance across thousands of mating cycles
- ELP (Eye-of-the-Needle Press-Fit) and FINAL INCH features support compliant-pin press-fit termination and precise board positioning without soldering, reducing thermal stress on adjacent components
- PEG board mounting option with keying (K) and tape-and-reel (TR) packaging enables mechanically secure SMT assembly with anti-mismatement protection for high-density stacking applications
What is SEAM-50-03.5-S-06-2-A-K-TR used for?
The SEAM-50-03.5-S-06-2-A-K-TR is designed for high-density board stacking in advanced telecom line cards, server backplanes, and FPGA-based processing platforms where reliable 100-position signal routing at 3.5 mm stack height is required. The ELP press-fit termination technology eliminates solder joints, enabling field-replaceable board assemblies in high-availability systems. Its SAMARRAY and SEARRAY compatibility allows engineers to build large connector arrays for multi-board signal aggregation in data center and switching equipment.

Frequently Asked Questions
What contact finish does the SEAM-50-03.5-S-06-2-A-K-TR use and how does it compare to standard gold plating?
The SEAM-50-03.5-S-06-2-A-K-TR uses Gold (30 µin) over Nickel (50 µin) contact finish, which provides 30 microinches of gold — 50% thicker than the 20 µin gold commonly used on lower-cost connectors. This heavier plating extends the reliable mating cycle life to thousands of insertions and improves performance in environments with mild oxidation or contamination, making it suitable for high-reliability telecom and aerospace board stacking applications.
What is the FINAL INCH feature on the SEAM-50-03.5-S-06-2-A-K-TR and when should engineers specify it?
The FINAL INCH feature refers to SAMTEC's compliant-pin press-fit termination technology, where the connector tails are pressed into plated-through holes using controlled insertion force without soldering. Engineers should specify this when designing hot-swap or field-replaceable board assemblies in telecom or server infrastructure, since it allows module removal and reinsertion without re-soldering, reducing maintenance downtime and eliminating solder joint fatigue across the 100-position interface.
For a server backplane requiring a 3.5 mm board-to-board stack height, is the SEAM-50-03.5-S-06-2-A-K-TR a suitable choice?
Yes, the SEAM-50-03.5-S-06-2-A-K-TR is specifically configured for a 3.5 mm board-to-board stack height, as encoded in the part number. This stack height is commonly used in 1U and 2U rack-mount server designs where daughtercard modules must sit close to the motherboard to fit within the chassis height constraint of 44.45 mm (1U). Combined with its 100-position count and 2.696 inch body length, it can service wide data buses including 64-bit parallel interfaces with control and power pins.
