Board Fit and Locking Retention
The 0462070012: This 12-position header sits on a 4.20mm pitch in two rows — the same footprint as the Mini-Fit Jr. receptacle family, so if you've already got the mating half in the harness, this header drops right into the board layout without a pitch mismatch.

Tin doesn't have the cycle life of gold, but in a panel that gets serviced a few times a year, this plating will outlast the equipment. The brass base material gives a solid spring characteristic for the square pin.
