What the 4-Pin 2.54mm Pitch Means for Your Board
The 77313-801-04LF shares the same 0.100" pitch, dual-row layout, gold mating finish, and 3A rating as the 6-position (77313-801-06LF) and 8-position (77313-801-08LF) versions. The only difference is circuit count: 4 positions vs 6 or 8. If your BOM calls for more I/O, the 6- or 8-pin sibling is a direct swap on the same footprint pattern — just longer.
