The FCI 68705-432HLF is a 32-position, single-row, unshrouded male pin header from the BERGSTIK® II series, designed for board-to-board interconnect applications. It uses a 0.100" (2.54 mm) mating pitch — the standard footprint for legacy through-hole designs — and carries all 32 positions loaded with square pins in phosphor bronze, finished with 100.0 µin (2.54 µm) of tin on the mating surface. The through-hole solder termination and push-pull fastening make it a straightforward drop-in for parallel board stacking or wire-to-board via a mating receptacle.
Key ratings and what they mean for the fit
Rated 5 A per contact at 110 V — this is signal-level current, not power bus duty. The 0.100" pitch gives enough room for routing traces between pads on a standard FR-4 board, and the 0.200" (5.08 mm) mating length provides a solid wipe for the receptacle contacts. The 100 µ" tin plating is thick enough for occasional mating cycles in a low-cost assembly; if your application needs frequent disconnect or operates in a corrosive environment, a gold-plated sibling in the same series would be the better call. The unshrouded design means there is no plastic wall around the pins — the mating receptacle housing provides the polarization and keying. For high-vibration environments or blind-mate scenarios, a shrouded header would offer better pin protection and alignment.
Construction and compliance
Housing is rated UL94 V-0, the standard flame class for equipment inside an enclosure. Contacts are phosphor bronze with a tin mating finish. The insulation height is 0.100" (2.54 mm), and the overall contact length of 0.395" (10.03 mm) includes a 0.095" (2.41 mm) solder post — check your board thickness and through-hole plating depth against the post length before committing the footprint.
