The Amphenol BERGSTIK® II 68438-472HLF is a 72-position (2×36), 0.100-inch (2.54 mm) pitch unshrouded male pin header for board-to-board signal interconnect. The UL94 V-0 black insulation and push-pull fastening suit it for internal board stacking in industrial control, telecom, and test equipment where the open pin field allows direct mating with a standard 0.100-inch receptacle.
The 0.100-inch pitch and 72-position count are common enough that a parametric search across the BERGSTIK II or similar unshrouded header families may yield a form-fit-function alternative, but no official cross-reference is available here.
The 0.100-inch pitch and 0.100-inch row spacing are the industry-standard 2.54 mm grid — the board footprint is a 2×36 array of 0.040-inch plated-through holes on that grid.
