The FCI 68705-423HLF is a 23-position, single-row unshrouded male pin header from the Bergstik® II series, designed for through-hole board-to-board stacking on a standard 0.100" (2.54mm) pitch grid. The square pins are phosphor bronze with a 100.0µin (2.54µm) tin finish on the mating surface and a 0.200" (5.08mm) mating length, rated for 5 A per circuit at 110 V. The black UL 94 V-0 rated housing sits at a 0.100" (2.54mm) insulation height above the board, with a 0.095" (2.41mm) solder post for the through-hole termination.
With 23 positions loaded in a single row at 0.100" pitch, this header occupies a board footprint 2.200" (55.88mm) wide between the outer pin centers. The 0.095" post length suits standard 0.062" to 0.093" thick PCBs.
Plating and duty
The 100.0µin tin mating finish is a production-grade choice for cost-sensitive assemblies with limited mating cycles — tin is suitable for permanent or infrequent connections. For applications requiring frequent disconnect-reconnect or exposure to corrosive atmospheres, a gold-plated variant from the same Bergstik II family would be the appropriate selection.
