Mates with the Economy Power 2.5 receptacle housing (TE part number 1-2834017-0 or similar) that accepts 20-24 AWG wire with the matching crimp terminal. The kinked pin solder tail (0.134" post length) gives a positive stop during through-hole insertion — the kink holds the pin at the correct board standoff before wave solder.
