Plating grade governs duty — not the headline current alone
The dual-beam square-pin contact and locking ramp fastening type add mechanical reassurance in any vibration-prone environment: the ramp locks the housing to the receptacle before the primary latch takes full load, so the interface does not back out during shipment or in-service flexing. The four-wall shroud and polarity slots prevent mis-mating with a mismatched circuit count — confirm the position count of your mating half before committing.
Board lock is the secondary retention during assembly
The board lock feature is the detail that separates this from a plain through-hole press-fit header. It engages the PCB during component placement and holds the header captive through the wave-solder thermal cycle — eliminating the floating-pin defect that plague large-connector assemblies. Post length of 0.125 inch (3.18 mm); check your board thickness against the insulator height of 0.290 inch (7.37 mm) when planning right-angle clearance in the enclosure. Two rows at 0.118 inch (3.00 mm) row spacing give a 20-position footprint on a 3.00 mm pitch — routing density is manageable at standard PCB stack-ups, but the dual-row layout demands the full connector footprint on the board, not just a single pin header edge.
