The insulation height of 0.356" (9.05 mm) and a mated stacking height of 21.30 mm define the z-height budget — confirm clearance in the enclosure before committing the layout.
No pin-compatible cross-reference from other manufacturers is documented. The Nano-Fit series is Molex-specific, so a second-source swap would require a board layout change.
The mating pitch is 2.50 mm, row spacing is also 2.50 mm, and the mated stacking height is 21.30 mm. The header is shrouded on all four walls.
