72-circuit BERGSTIK unshrouded header
The 861400722YO2LF is the 72-circuit member of Amphenol ICC (FCI)'s BERGSTIK breakaway header line, a dual-row unshrouded square-pin header for board-to-board or cable applications. Rated 3 A per contact at 1000 V, the header carries gold or GXT™ plating on the mating surface with 8.00 µin (0.203 µm) thickness, suiting repeated mating cycles in signal-level interconnects.
Board footprint and stack height
At 0.100" (2.54 mm) pitch with a 0.100" (2.54 mm) row spacing, the 72-position header occupies a 36 × 2 grid on the PCB. The overall contact length of 0.496" (12.60 mm) breaks down into a 0.276" (7.00 mm) mating tail and a 0.118" (3.00 mm) solder post, defining the board-to-board stack height when mated with a matching receptacle.
