The Amphenol BergStik II 86837-136HLF is a 36-position, 2-row unshrouded male pin header on 0.100" (2.54mm) pitch — a standard-density board-to-board interconnect for parallel or perpendicular PCB stacking. The 5 A per circuit rating at 110 V covers typical signal and low-power distribution duties; the 30.0 µin (0.76µm) gold plating on the mating surface handles repeated connect-disconnect cycles without contact fretting, which matters more in field-service or test-fixture applications than in a one-time assembly.
As an unshrouded header with push-pull fastening, the 86837-136HLF mates with any standard 0.100" pitch, 36-position female socket strip that accepts a 0.025" square pin — the BergStik II receptacle series or equivalent. The 0.380" (9.65mm) mating pin length gives enough wipe for a reliable contact interface. Board layout needs the 0.100" row spacing and 0.120" (3.05mm) post length for the through-hole solder tail; the 0.600" (15.24mm) overall contact length sets the stack height between boards when mated with a matching receptacle.
