Board-to-Board or Cable Header with 5.08mm Pitch
The 2-917657-5: The 5.08mm pitch and 7.62mm row spacing set the PCB footprint — a standard industrial power-and-signal layout that keeps routing density manageable.
Stack Height and Board Lock for Mezzanine Fit
Mated stacking heights of 31.00mm to 32.50mm define the board-to-board gap — a critical dimension for mezzanine card spacing. The 0.150" (3.81mm) solder post length gives enough standoff for wave-solder fillet inspection without protruding through the far side of a standard 1.6mm PCB.
