The 5.08 mm pitch and 7.62 mm row spacing set the board footprint — each contact sits on a 0.200-inch grid, which is wider than the 2.50 mm pitch of many signal headers, giving more room for trace routing between pins on the PCB. Mated stack height runs 31.00 mm to 32.50 mm, measured from the board surface of the header to the mating face of the receptacle. That z-height budget suits mezzanine or board-to-wire applications where the header stands off from the PCB by roughly 1.2 inches. In a vibration environment, those locks prevent the header from lifting off the board pads.
