The Amphenol FCI 86832-140HLF is a 40-position dual-row unshrouded header from the BERGSTIK II series, on the standard 0.100" (2.54 mm) pitch that defines the classic PC/104 and legacy ISA-bus footprint. All 40 positions are loaded — no skipped pins to track down in the BOM. The through-hole solder tails and 0.100" (2.54 mm) mating and row spacing mean it drops into the same board layout as any industry-standard 0.100" x 0.100" header pattern. Rated 5 A per circuit at 110 V, this is a signal-level interconnect — the current rating is typical for a 0.025" square pin at this pitch, and the 30.0 µ" (0.76 µm) gold or GXT plating on the mating surface gives it the cycle life for repeated board-to-board matings in test equipment, programming jigs, or modular card cages. This is standard for BERGSTIK II headers that pair with IDC sockets or crimp receptacles in non-vibration applications.
The 0.100" (2.54 mm) pitch and 0.100" (2.54 mm) row spacing define a 0.100" x 0.100" grid — the same footprint used by the BergStik, Samtec TSW, and 3M 929 series headers. The 0.100" (2.54 mm) post length suits standard 0.062" (1.6 mm) PCBs; for thicker boards the solder tail may need a longer-post variant.
