The 76314-222LF: The 2-row layout with 0.100" row spacing means the PCB footprint is a 2×22 array of 0.025" square holes on a 0.100" grid, matching the mating header pin pattern exactly.
Mating Half and Assembly BOM
This receptacle mates with any BergCon dual-row 0.100" pitch header of the same 44-position count. For a complete build-to-print assembly, you need the receptacle body (this part), the mating header (e.g., BergCon 76314 series header), and the through-hole solder connection — no separate contacts or backshell required. The housing is glass-filled thermoplastic, UL94 V-0 rated, in blue insulation.
