The FCI 91276-106HLF is a 6-position, single-row, unshrouded male pin header from the BERGSTIK® II series. It is a board-to-board interconnect, designed for through-hole soldering onto a PCB, with a standard 0.100" (2.54 mm) pitch that matches a wide range of legacy and current board layouts. The square pins are phosphor bronze with a 30.0 µin gold or GXT™ finish on the mating surface, rated for 5 A per contact at 110 V. The black UL94 V-0 rated housing and push-pull fastening make it a straightforward, no-frills choice for internal PCB stacking where the mated connection is semi-permanent.
What the ratings mean for the fit
The 0.100" (2.54 mm) pitch is the key footprint dimension — it dictates the hole pattern on the PCB and the mating receptacle. A 6-position, single-row unshrouded header like this mates with any standard 0.100" pitch, 6-position female socket housing, such as the common IDC or crimp-type receptacles used in ribbon cable or discrete wire harnesses. The 5 A per-contact rating is typical for this pitch class; it handles signal-level currents comfortably and can carry moderate power, but the real limit in a dense board stack is often the temperature rise in the surrounding traces, not the contact itself. The 30.0 µin gold plating on the mating side is a solid industrial-grade finish — it will hold up through repeated mating cycles in a clean, controlled environment without the fretting corrosion you'd see with tin on tin in a high-vibration setting.
