What the 75160-118-25LF is and where it sits in the BERGSTIK series
The Amphenol FCI 75160-118-25LF is the 25-position member of the BERGSTIK single-row board-to-board header series, operating at the industry-standard 0.100 inch (2.54 mm) pitch. It is an unshrouded through-hole male-pin header with a push-pull fastening style, gold-plated contacts on the mating face, and square post termination — a configuration that fills a standard 2.54 mm grid footprint on the PCB and mates with the matching BERGSTIK receptacle housing. The insulation height of 0.100 inch (2.54 mm) matches the mating pitch exactly, meaning the connector's plastic body sits flush at a 1:1 ratio relative to its pin spacing — a clean stack geometry for board-to-board stacking applications where the mated pair occupies a predictable z-height budget.
What the ratings govern
Rated 110 V — this is signal-class at 0.100 inch pitch, not a power header, so the circuit voltage budget should stay well below 110 V in any application using this part. The 5 A per contact current rating reflects the phosphor bronze contact geometry and plating thickness, which supports both power distribution and general-purpose signal paths at this pitch. The contact finish on the mating face is gold, GXT(TM), at 30.0 microinches (0.76 micrometres) — a mid-gold thickness that provides better wipe durability and oxidation resistance than thin flash gold, extending the useful mating cycle window. The base contact material is phosphor bronze, which is standard for square-post headers at this pitch and pitch class. Operating temperature range is -65 to 130 degrees C, which is broad for a general-purpose board-to-board header — the upper limit accommodates elevated-temperature environments without derating concerns at the stated 5 A rating within that window. The material flammability rating is UL94 V-0, which is the highest flame-retardance classification for connector-grade thermoplastic and is typically required for industrial and instrumentation equipment enclosures.
Sourcing and lifecycle
The 75160 base product number anchors this single-position-count member of the BERGSTIK series. All variants in the series share the same 0.100 inch (2.54 mm) pitch and through-hole footprint, with position count as the primary differentiating parameter.
