The 0448120012: The push-pull fastening and bottom-or-top-entry design allow flexible board orientation; the through-hole solder termination with 0.136" (3.46 mm) post length provides a stable mechanical anchor for the mated pair.
As a board-to-board receptacle, it mates with a pin header from the same KK254 series (0.100" pitch, single row, 12 positions). The exact mating header part number depends on the desired stack height and termination style.
The receptacle has 12 positions in a single row, all loaded. Pin 1 is typically indicated by a triangle or chamfer on the housing; the exact pin numbering follows the standard Molex KK254 layout.
