The FCI BERGSTIK® II 68697-454HLF is a 54-position unshrouded male pin header on a standard 0.100" (2.54 mm) pitch, arranged in two rows with the same 0.100" row spacing. This is a board-to-board interconnect — the unshrouded design mates with a female socket header (BergStik or compatible 0.100" pitch receptacle) for parallel or perpendicular PCB stacking. The right-angle through-hole termination places the pin rows parallel to the board edge, suiting it for mezzanine or edge-card connections where the cable or mating board exits at the PCB perimeter.
Key ratings and what they mean for the fit
The 0.100" pitch is the legacy DIP-compatible spacing — it matches standard perfboard and prototyping grids, and the footprint is a drop-in for many 0.100" receptacle headers. The 54-position count is fully loaded (all positions populated), so the pinout is a straight 2×54 grid; no skipped or dummy pins to account for. Rated 5 A per contact with tin-plated mating surfaces — the tin finish is cost-effective for moderate mating cycles (tens of mates) in indoor, low-corrosion environments; for frequent reconnection or harsh atmospheres, a gold-plated variant in the same series would be the better choice. The UL94 V-0 housing is standard for equipment inside an enclosure requiring flame retardance.
