Its 0.016" (0.40 mm) pitch and 0.027" (0.68 mm) height above the PCB let it fit into tight z-axis gaps between stacked boards — the mated stacking height lands at 0.7 mm.
The pick-and-place vacuum area and solder retention tails are built into the part — no separate hold-down hardware is needed during reflow.
The mated stacking height is 0.7 mm, with the receptacle sitting 0.027" (0.68 mm) above the PCB surface. This defines the z-axis clearance between the two parallel boards in the mezzanine stack.
