The FCI 68020-454HLF is a 54-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect applications. It uses a 0.100" (2.54mm) pitch on both the mating and row spacing, making it a direct footprint match for standard 0.100" grid layouts. The right-angle through-hole termination suits board-edge or mezzanine stacking where the connector axis runs parallel to the PCB.
Key Ratings and What They Mean for Fit
With 54 positions loaded across two rows, this header matches a 54-circuit BOM line exactly — no unused positions to manage. The 0.100" pitch is the industry-standard 2.54 mm grid, so the footprint lands on a 0.100" x 0.100" hole pattern that most PCB layout tools have as a library default. Tin plating on both the mating contact and the post (100.0 µ in / 2.54 µm thickness on the mating side) suits infrequent mating cycles. The 3 A per contact rating covers typical signal and moderate power duty. The unshrouded, push-pull fastening means there is no housing shroud to guide alignment — the mating receptacle must provide its own alignment features. The 0.230" (5.84 mm) mating pin length and 0.095" (2.41 mm) post length are fixed; confirm the mating receptacle's depth and the PCB thickness before committing the board stack.
