A built-in board guide aligns the mating halves during assembly, protecting the fine-pitch contacts from shear damage.
Mated Stacking Heights and Board Spacing
This receptacle supports two mated stacking heights: 14mm and 15mm. The choice depends on the mating header variant used — the height above board of this part is 0.406" (10.30mm). For a 14mm stack, the mating header height must be 3.70mm; for 15mm, 4.70mm. Verify the header part number against the stack height needed for your board-to-board clearance.
