The 4-2232826-9: The 2 A per-contact ceiling is conservative for tin-plated contacts — expect the temperature rise to stay within the housing limit at full load in still air. The latch holder (not a simple detent) provides positive retention against cable pull or vibration, a step up from friction-only headers. Mates with the corresponding Grace Inertia 2.0 receptacle housings using the standard crimp terminals.
