The 1586627-1: The 0.200" (5.08mm) pitch gives each pin enough spacing to carry 12A per contact without thermal crowding — a common choice for power distribution on a PCB where you need a detachable wire harness.
Footprint and mounting for the board layout
The insulation height of 0.375" (9.53mm) above the board surface leaves clearance for wire routing under the mated connector.
Rated 12A per contact at 250VAC — the tin-on-tin contact interface (80.0µin mating finish) handles this current comfortably, but the tin plating limits the connector to roughly 25-50 mating cycles before wear-through.
