The Amphenol ICC 87901-420HLF is a 20-position, dual-row unshrouded header from the BERGSTIK® II series, on the standard 0.100" (2.54 mm) pitch that defines the board-level footprint for this class of interconnect. This is a through-hole, solder-terminated male pin header with a push-pull fastening system — no locking ramp, no shroud — designed for board-to-board stacking where the mating receptacle provides the retention. The 20 positions are fully loaded across two rows, with a row-to-row spacing of 0.100" (2.54 mm), giving a symmetrical grid that matches standard 0.100" IDC sockets or female headers.
The 5 A per-contact current rating is standard for this pitch and contact geometry. The 110 V voltage rating sets the working voltage for the board-level insulation path. The 0.100" (2.54 mm) pitch and 0.100" row spacing create a standard 0.100" x 0.100" grid.
This is a standard catalog header, not a custom or phased-out line item.
