What this connector is
The Amphenol BERGSTIK 75844-102-72LF is a 72-circuit dual-row breakaway header in the BERGSTIK family, designed for board-to-board or cable interconnect at 0.100 inch (2.54 mm) pitch. Square male pin contacts in phosphor bronze carry 5 A per circuit with gold GXT plating at 30 microinches thickness on the mating face; the push-pull fastening holds the mated pair without a jackscrew. All 72 positions are fully loaded. The black thermoplastic housing is UL94 V-0 rated and the connector operates from -65 to 130 degrees C, making it suited for industrial instrumentation and communications equipment where a rugged through-hole board-mount header is the interconnect medium.
What the key ratings mean for your BOM
The 0.135 inch (3.43 mm) post length and 0.230 inch (5.84 mm) mating contact length give adequate board-side standoff for through-hole soldering; the 0.465 inch (11.81 mm) overall contact length is the dimension to check against the board thickness and any opposing connector's entry depth. The 0.100 inch (2.54 mm) insulation height is a tight board-profile spec — confirm the z-height budget for the mated assembly fits the enclosure.
