The Amphenol FCI 67998-420HLF is a 20-position dual-row unshrouded header from the BERGSTIK II series, on the standard 0.100" (2.54 mm) pitch grid. It carries tin-plated phosphor bronze male pins rated 5 A per circuit at 110 V, terminated by through-hole solder into a black UL94 V-0 housing. This is a board-to-board interconnect — the unshrouded design leaves the pins exposed for direct mating with a receptacle or for use as a programming/test header, common in industrial control, telecom line cards, and embedded computing where the 0.100" grid matches legacy PCB layouts.
What the ratings mean for the fit
The 0.100" (2.54 mm) pitch is the de facto standard for 0.1-inch grid prototyping and production boards — the footprint is a 20-pin dual-row pattern with 0.100" row spacing, so the board layout is straightforward if the existing pattern matches. The 5 A per circuit rating is typical for this pitch and contact size; the limiting factor in practice is the temperature rise through the tin-plated interface, so derate above 25 °C ambient. Tin-on-tin mating finish (100.0 µin on the mating side) is cost-effective for one-time assembly or low-cycle applications — it wears faster than gold under repeated mating, so if the board sees field-service reconnects, consider a gold-plated variant in the same series.
