Product details

1.27 mm pitch, 40-circuit board-to-board header

The 73547-120LF: Rated 1 A DC per circuit.

Rib-Cage III series — shared footprint, varied stack heights

The Rib-Cage III family uses the same 1.27 mm pitch and 0.050" row spacing across all position counts, so the board footprint for the 40-position 73547-120LF is shared with the 20-, 30-, 50-, and 60-position siblings. The mated stack height of 9.93 mm is fixed for this part; other members of the series offer different stack heights to match the board-to-board z-budget.
