The Amphenol FCI 75160-101-04LF is a 4-position unshrouded male pin header from the BERGSTIK® series, built for board-to-board interconnects on a standard 0.100" (2.54mm) pitch. It's a single-row, through-hole part with push-pull mating and a square pin contact geometry. The 30.0µin gold GXT™ plating on the mating surface handles repeated connect-disconnect cycles without fretting corrosion, while the UL94 V-0 thermoplastic housing keeps it compliant for equipment inside an enclosure.
The 0.100" (2.54mm) pitch is the industry-standard spacing for prototyping and legacy board layouts — you can route a single trace between pads on a standard 1 oz copper board without necking down. The 5A per-contact rating is honest for a pin this size; the limiting factor is the temperature rise in the housing, not the contact itself, so keep the total current across all 4 positions under 20A and you're fine. The 30.0µin gold GXT™ finish is thicker than the typical 15µin flash — it's meant for applications where the board gets mated and unmated more than a few times over its life, like a test fixture or a field-replaceable module.
No official cross-reference or pin-compatible alternative is on record, so match the 4-position count and 0.100" pitch to your BOM line directly.
