The Amphenol 75844-156-12LF is a 12-position, unshrouded male pin header from the BERGSTIK® series, designed for board-to-board or cable interconnect applications. It uses a 0.100" (2.54mm) pitch in a dual-row configuration, a standard footprint for prototyping and production. The header is rated for 5 A per contact at 110 V, with gold GXT™ plating on the mating surface at 30.0µin (0.76µm) — a thickness that supports repeated mating cycles in corrosive or field-service environments. The through-hole solder termination and push-pull fastening make it a straightforward fit for wire-wrap or soldered backplanes.
The 0.100" (2.54mm) pitch is a de facto standard for general-purpose PCBs — it gives enough room for routing a trace between pads without forcing a fine-line board. The 30.0µin gold on the mating side is the real differentiator here: it resists fretting corrosion and maintains low contact resistance through hundreds of cycles, unlike tin which can oxidize in low-current signal paths. The UL94 V-0 thermoplastic housing meets the flame rating required for equipment installed inside an enclosure.
