The Molex 68023-436 is the 36-circuit member of the BERGSTIK II board-to-board header series — a single-row, 0.100 inch (2.54 mm) pitch unshrouded male pin header in a right-angle through-hole configuration. The housing is UL94 V-0 black thermoplastic, and the push-pull push-pull fastening type holds the mated pair without jack-screws or latching clips — the friction fit is sufficient for stable board-to-board stacking when the PCB spacing is fixed at assembly. Contacts are square phosphor bronze pins, tin-plated on the mating interface at 100.0 µin (2.54 µm) thickness, and the header ships fully loaded with all 36 positions populated.
Current and voltage ratings
The 5 A per-contact current rating at 110 V sits comfortably within the derating window for tin-plated contacts on a board-to-board signal or low-power interconnect — the limiting factor on cycle life is the plating wear at repeated mates, not the current-carrying capacity itself. The tin finish at 100.0 µin (2.54 µm) is on the thicker end for this grade, which helps with solderability and shelf oxidation but does not extend mating cycles to the level a gold-flash or gold-over-nickel contact would sustain. For applications requiring more than a few dozen matings, a gold-plated BERGSTIK variant would be the series-internal alternative.
