The Amphenol FCI 67998-204HLF is a 4-position (2×2) unshrouded dual-row header from the BERGSTIK II series, on the standard 0.100" (2.54 mm) pitch. It's a through-hole, push-pull board-to-board interconnect — the kind you'd see as a programming header, a compact board jumper, or a low-profile mezzanine link where you don't need a shroud to guide the mate. The square male pins are phosphor bronze with 15.0 µin (0.38 µm) gold on the mating surface, rated 5 A per contact at 110 V.
Within the BERGSTIK II dual-row unshrouded header family, the 67998-204HLF sits at the low end of the position count — 4 positions against the more common 10, 20, or 34-position variants at the same 0.100" pitch and 5 A rating. The decision is purely about circuit count: if your BOM calls for exactly 4 pins in a 2×2 layout, this is the one. No difference in footprint spacing or current headroom — just the number of pins loaded.
The 0.100" pitch and 0.100" row spacing match the legacy DIP footprint grid — no board layout surprise if you're dropping this onto a 0.100"-center through-hole pattern.
