The FCI Electronics 91276-403HLF is a 3-position, single-row, unshrouded male pin header from the BERGSTIK® II series. It uses a 0.100" (2.54mm) pitch — the standard breadboard-compatible spacing that matches perfboard and common IC footprints. The through-hole termination with 0.225" (5.72mm) solder tails gives a solid mechanical anchor for hand-wired or low-density PCB layouts. Rated 5A per contact at 110V, the tin-plated phosphor bronze contacts handle general-purpose signal and low-power duty in board-to-board or wire-to-board applications. The UL94 V-0 black insulation suits equipment inside an enclosure requiring flame-rated materials.
Fit and footprint
The 0.100" (2.54mm) pitch and single-row layout mean the 91276-403HLF occupies a narrow 3-position strip on the board — the overall contact length is 1.225" (31.12mm) with a 0.900" (22.86mm) mating pin length. The unshrouded design gives the technician full visual access to the solder joints and allows mating with standard 0.100" pitch crimp receptacles or IDC sockets. No keying or polarization is built in, so orientation is set by the PCB footprint and the mating half's housing geometry.
Sourcing and lifecycle
The 91276-403HLF carries an Active lifecycle status from the manufacturer — full production, no end-of-life notice. No official cross-reference or direct replacement is on record, so the BOM position should be matched to this exact order code.
