Pitch, positions, and the footprint it needs
At 1.50 mm pitch, this header demands a tight board layout — trace fan-out between the through-hole pads is feasible on a two-layer board if the traces are kept to 0.20 mm width. The 0.118 inch (3.00 mm) post length gives enough solder tail for a standard 1.6 mm PCB thickness. That mating pin reach is enough to engage the receptacle contact beam fully, but tight for applications requiring a long wipe before lock.
