The Amphenol FCI 92634-444HLF is a 44-position, dual-row unshrouded header from the BergStik II series, designed for board-to-board interconnect on a standard 0.100-inch pitch. It uses through-hole, right-angle mounting — the pins sit parallel to the PCB plane, which suits board-edge applications where the mating receptacle exits sideways rather than straight up. The 5 A per-contact current rating and tin-on-tin contact system are typical for signal-level duty inside an enclosure; the 100 µin tin plating on the mating surface gives a solid cycle life for moderate-insertion applications without the cost of gold.
Footprint and fit
The 0.100-inch pitch and 0.100-inch row spacing are the legacy through-hole grid — any board laid out for a standard 0.100" dual-row header accepts this part without a footprint change. The 44 positions load all pins (no skipped positions), so the BOM circuit count must match exactly. The unshrouded design means no polarization keying: the mating receptacle must be oriented correctly by the board layout or harness routing, not by a mechanical shroud.
Contact system and ratings
Phosphor bronze square pins with tin plating on both the mating and solder-post surfaces. The 100 µin tin thickness on the mating side is a heavy-duty tin finish — it handles repeated mating cycles better than a flash tin, though it still prefers a tin-mating receptacle to avoid galvanic mismatch. Rated 5 A per contact at an unspecified ambient; the UL94 V-0 housing keeps the assembly compliant for equipment inside a fire-rated enclosure. The 110 V voltage rating is the working limit between adjacent pins at the stated pitch.
