The Amphenol FCI 68023-418HLF is an 18-position single-row unshrouded header from the BERGSTIK® II series, on the standard 0.100" (2.54 mm) pitch. The tin-plated phosphor bronze contacts are rated 5 A per circuit at 110 V, with a 100.0 µin (2.54 µm) mating-side finish that handles occasional reconnection well in low-cycle environments. The black UL94 V-0 housing suits equipment requiring a flame-rated enclosure.
The 0.100" (2.54 mm) pitch is the legacy breadboard-compatible spacing — it matches the vast installed base of 0.100" receptacles and perfboard layouts, so the board footprint is a drop-in for standard strip headers. The 18-position single-row count is the exact BOM line match; all positions are loaded, so no depopulated variants to track.
