The push-pull mating style and UL94 V-0 black housing suit it for general-purpose PCB stacking where a low-profile, unshrouded interface is acceptable.
The 5 A figure is per-contact at ambient — derate above 25 °C per the manufacturer's curve.
The 2 positions are loaded across 2 rows (one position per row), with a row spacing of 0.100" (2.54 mm). The overall contact length is 0.940" (23.88 mm), with a mating length of 0.720" (18.29 mm) and a post length of 0.120" (3.05 mm) — confirm the board thickness and mating half stack height against these dimensions.
