The DF9A-41S-1V(22): It sits at the high end of the position count in the DF9A family, offering the most interconnects in the same 1.00 mm pitch footprint.
At this pitch, the board designer needs to account for trace escape between the pads, typically using a via-in-pad or fine-line routing strategy for the inner rows. The 2-row arrangement packs 41 circuits into a compact body, making it a space-efficient choice for dense signal harnesses on mezzanine cards.
The mated stack height is 4.3 mm, which defines the z-axis clearance between the two PCBs when the connector pair is fully mated.
