The Amphenol BERGSTIK® 75844-102-04LF is a dual-row, 4-position unshrouded breakaway header rated 5 A per contact at 110 V — a board-to-board or cable interconnect at the classic 0.100" (2.54 mm) pitch. Gold-over-nickel contact plating at 30 µin gives this header meaningful reconnection cycle life compared to tin-only alternatives, while the push-pull fastening type and square pin cross-section keep it compatible with matching IDC or machine-pin receptacles in the BERGSTIK® family. Black thermoplastic housing carries a UL94 V-0 flammability rating and an operating range from -65°C to 130°C, placing it in heated-enclosure and light-industrial environments where the header sits inside the equipment rather than exposed at the panel face.
Board layout fit
Through-hole solder tails on a 0.100" grid mean this header lands on any standard 0.100" pitch PCB footprint — the same routing grid used by virtually every through-hole pin-header family at this pitch. The post extends 0.135" (3.43 mm) below the insulation shoulder with a total contact length of 0.465" (11.81 mm); the mated engagement length is 0.230" (5.84 mm). Row spacing matches the mating pitch at 0.100", giving a 0.100" × 0.100" row/column grid. All four positions are loaded — no partially populated option on this part number.
Mates with any standard 0.100" pitch IDC or machine-pin socket in the same series — the square male pin cross-section is industry-standard at this pitch. The unshrouded header does not carry polarisation features of its own; alignment and keying depend entirely on the socket or the PCB pattern. All four positions are loaded, so confirm the mating receptacle also carries four contacts before committing the BOM line.
