The Amphenol FCI 91276-119HLF is a 19-position, single-row unshrouded male header from the BERGSTIK II series. It uses a 0.100" (2.54 mm) pitch. Rated 5 A per contact at 110 V. The contact finish is gold or GXT at 30.0 µin (0.76 µm) on the mating surface — that thickness supports repeated mating cycles without exposing the phosphor bronze base metal to oxidation, which matters if the board goes through multiple test-and-rework passes before final assembly. The unshrouded design means the pins are exposed; the mating connector must provide its own polarization or keying. The housing is rated UL94 V-0, so it meets the flame-retardant requirement for equipment installed inside an enclosure.
Within the BERGSTIK II single-row unshrouded header family, the 91276-119HLF at 19 positions sits between the 10-position and 20-position variants at the same 0.100" pitch and 5 A rating. The position count is the only selection variable — the footprint pitch, current rating, and post length are identical across the series, so the choice comes down to matching the circuit count on the BOM.
