The 647290-1: Only 2 positions are loaded with tin-plated square pins; the third position is a vacant through-hole location. The header mates with MTA-156 receptacle housings and uses the matching crimp terminals (series 640250 for 18-24 AWG, series 640256 for 26-30 AWG). Through-hole mounting provides a solder-joint anchor that handles cable strain better than a surface-mount footprint — important for a board-to-cable/wire connection where the harness is routed and flexed in service.
