The 4-644456-0: The 10-position single-row layout keeps the board-edge routing simple and the z-height low.
For a 20 AWG wire in a typical MTA-100 receptacle, the practical current limit is around 5 A per circuit at 30 °C ambient. Derate above 85 °C ambient per the series derating curve.
It mates with MTA-100 series IDC receptacles or crimp-socket housings, same 0.100" pitch, 10 positions. The unshrouded header has no keying — the mating half must be aligned manually.
