A single 5177983-5 receptacle supports mated stacking heights of 5 mm, 6 mm, 7 mm, and 8 mm — the actual height is set by the mating plug's standoff, not the receptacle. That means one BOM line covers several board-spacing requirements, which simplifies inventory if you run multiple card gaps across a product family.
The 5177983-5 is sourced to order through independent distribution.
Compatibility hinges on three checks: the 0.80 mm pitch must match your PCB footprint, the 120 positions must match your circuit count, and the 3.75 mm height above board plus the chosen mated stack height (5 mm to 8 mm) must fit your card spacing.
