The FCI 92634-454HLF is a 54-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect on a standard 0.100" (2.54 mm) pitch grid. It uses square male pins with a tin-plated mating surface and a tin-plated solder post, terminated through-hole in a right-angle orientation. The header carries a 5 A per-contact rating and is housed in a UL94 V-0 rated black insulator.
Ratings and fit
The 54 positions, fully loaded across two rows, give 27 contacts per row; the BOM line must match this exact count.
