The 967646-1: 12 positions in a dual-row layout means the connector occupies roughly 0.6" of board edge for the row length, plus the 0.795" insulation height above the board — plan the z-height budget around that 20.20mm standoff.
Through-hole solder termination: the 0.110" (2.79mm) post length is standard for 1.6mm PCBs.
