The 0039299043: The 0.165" (4.20 mm) row spacing matches the standard Mini-Fit Jr receptacle footprint, so the board layout engineer can drop this into a 2×2 pattern without recalculating keep-outs. The shrouded 4-wall design and locking ramp prevent mis-mating and hold the connector pair engaged under vibration.
