The 5018762240: This is a 22-position, 2-row right-angle through-hole header from the Molex iGrid 501876 series. It mates with a board-to-cable/wire receptacle — not another board — so it's a wire-to-board interconnect, not a mezzanine stacker.
Sizing the PCB footprint and orientation
The post length is 3.20mm, so the solder tail reaches through a standard 1.6mm board with room for a wave-solder fillet. The latch holder adds a bit more height at the lock tab, but the 8.30mm dimension is the one to check for enclosure clearance.
RoHS3 compliant per the current directive. Housing is UL94 V-0 rated PA66 glass-filled nylon.
