The Amphenol 75160-150-06LF is a 6-position, single-row, unshrouded male pin header from the BergStik® series, on the standard 0.100" (2.54mm) pitch. It's a through-hole solder termination, push-pull fastening, board-to-board interconnect — the kind of general-purpose header you find on prototype boards, test fixtures, and low-density production interconnects where the 2.54mm grid matches legacy DIP footprints or perfboard layouts. The 5A per-contact current rating and 110V voltage rating place it firmly in signal-level duty, though it can handle light power distribution within those limits.
The 0.100" pitch is the main footprint driver — it matches the standard 0.100" x 0.100" grid, so your PCB layout uses a 6-pin single-row header footprint with 2.54mm between centres. The 0.123" (3.12mm) solder post length is sized for a 1.6mm (0.062") PCB — it'll protrude enough for a clean through-hole solder fillet but won't extend so far that it interferes with components on the back side. Standard 15µ" gold is common for low-cycle internal connections; 30µ" gold with GXT alloy gives you roughly double the mating cycle life before wear-through — think 200+ cycles in a test or field-service environment.
