Sizing the Z-Height and Board Spacing
The 76341-331LF: The 11.04 mm mated stack height is a fixed dimension – the receptacle mates with a matching Dubox™ header to create a rigid board-to-board connection at that spacing. The insulation height of 0.275" (6.99 mm) plus the 0.114" (2.90 mm) solder tail length determine the through-hole depth and keep-out zone on the secondary side. Single-row, 31 positions loaded all – every contact position is active, so the BOM count matches the circuit count exactly.
The blue insulation colour aids visual identification during assembly.
