The Amphenol FCI 86832-442HLF is a 42-position unshrouded male pin header from the BERGSTIK® II series. It uses a dual-row layout on a 0.100" (2.54mm) pitch with a matching 0.100" (2.54mm) row spacing, giving a dense but standard grid for board-to-board stacking or wire-to-board connections through a mating receptacle. The header is through-hole soldered, with tin-plated phosphor bronze contacts rated 5 A per circuit at 110 V. The unshrouded design means there is no polarization key or latch — alignment depends on the board footprint and the mating connector's housing.
Key specs and what they mean for the fit
The 42 positions are fully loaded across two rows — 21 per row — so the BOM line count must match exactly. The 0.100" (2.54mm) pitch is the industry-standard grid for this class of header, which means the footprint is compatible with a wide range of BergStik and equivalent receptacles. The 5 A per circuit rating is typical for tin-plated contacts at this pitch; the limiting factor is the temperature rise in the housing, not the contact beam itself. The 100.0 µin (2.54 µm) tin plating on the mating surface is thick enough for occasional mating cycles in a production assembly, but not designed for frequent field reconnection — gold-plated variants in the same series would be the choice for repeated mate/unmate duty.
