It sits on a 0.100" (2.54mm) pitch with matching 0.100" row spacing, making it a standard footprint for board-to-board stacking or wire-to-board through a mating receptacle. Rated 5 A per contact with a 30.0µin gold mating finish over phosphor bronze, it handles repeated mating cycles in signal-level applications — the gold thickness supports field-service reconnect without fretting corrosion concerns. The through-hole solder termination and 0.120" (3.05mm) post length suit it for plated through-hole PCB assembly.
As an unshrouded header with push-pull fastening, the 79425-122HLF mates with any standard 0.100" pitch dual-row receptacle housing — the matching half is a separate BOM line. The 0.190" (4.83mm) mating contact length provides a solid wipe for the receptacle's female contacts. Build-to-print needs both halves specified; the receptacle, crimp terminals, and any backshell or strain relief are sold separately.
