The 640385-3: The 0.390" (9.91mm) mating pin length provides enough engagement depth for standard MTA-156 receptacle contacts. The 0.125" (3.18mm) solder post length is typical for through-hole boards up to 1.6mm thick.
RoHS compliant. The base product number is 640385, so the -3 suffix indicates the 3-position variant within the series.
The mating half is an MTA-156 receptacle housing (unshrouded header mates with the corresponding receptacle). The 3.96mm pitch and single-row layout are shared across the series — select the receptacle with the same circuit count and the matching crimp terminal for your wire gauge.
