What this connector is
The Amphenol FCI BERGSTIK 75160-156-04LF is a single-row unshrouded header in the BERGSTIK family, rated for board-to-board interconnects. It carries 4 positions on a 0.100 inch (2.54 mm) pitch — the standard 2.54 mm grid used across through-hole prototyping and legacy digital signal buses. Male pin contacts in phosphor bronze, gold-plated to 30 µin (0.76 µm) on the mating face, are rated 5 A per circuit at up to 110 V. Termination is through-hole solder; the push-pull fastening type indicates a friction-lock mate with the matching receptacle — no tool actuation required, but the pair relies on normal insertion force to stay seated in a vibration-prone environment. The thermoplastic housing is UL94 V-0 rated, which satisfies the flammability requirement in most industrial and instrumentation panels.
Key ratings for fit decisions
Pitch (0.100 inch / 2.54 mm) and 4 positions are the two numbers that decide whether this fits a standard DIP footprint or a 2.54 mm daughtercard pattern — it is drop-in compatible with any through-hole layout sized for the 0.100 inch grid. The gold plating grade (30 µin / 0.76 µm, GXT designation) places this well above tin in both corrosion resistance and mating cycle durability; it is suitable for multiple mate/unmate cycles in test-fixture or field-service scenarios. The 5 A per circuit rating handles low-level power rails and logic-level signal buses without de-rating. Operating temperature spans -65°C to 130°C, wide enough for industrial enclosure interiors and automotive under-hood zones short of the engine bay.
Mating and sourcing reality
As a male pin header, this mates with the matching BERGSTIK receptacle housing — confirm the position count matches before committing. The listing carries Active lifecycle status; no official cross-reference or successor order code exists, so sourcing is against the listed BOM quantity via RFQ. The 0.100 inch pitch, 4-position count, and GXT gold plating together define the selection; if any of those three parameters shifts in your BOM, the alternate will not be pin-compatible.
