What this connector is
The Amphenol FCI Bergstik 75844-118-72LF is a 72-position dual-row 0.100" (2.54 mm) pitch male pin header designed for board-to-board or cable interconnect. It is an unshrouded breakaway header — the square pins accept any 0.100" pitch IDC or wire-wrap receptacle, and the push-pull fastening type means it relies on friction and header-to-socket contact pressure rather than a locking latch. Phosphor bronze contacts with 30.0 µin (0.76 µm) gold GXT plating on the mating surface give it 5 A per circuit at the stated rating, and the thermoplastic housing carries a UL94 V-0 flammability rating — the combination that makes it a standard go-to for internal commercial equipment and industrial control cards where the board stack needs a bare, flexible pin header.
Board fit and stack-up
Through-hole solder termination with a post length of 0.120" (3.05 mm) and overall contact length of 0.445" (11.30 mm) — the header sits flush with the board surface and the pin extends enough to engage a mid-stack or wire-wrap receptacle without needing an extended-tail variant. The 0.100" insulation height matches the row spacing, so the mated pair sits coplanar to the board at approximately 0.100" stack height — standard for 0.100" pitch mezzanine or daughter-card retention. All 72 positions are loaded, so there is no partial-position option on this specific part number.
