The mating contacts are gold-plated to 30.0µinch (0.76µm) over nickel, while the solder tails receive a 100.0µinch (2.54µm) tin finish.
Board Fit and Routing: 0.100" Pitch, Right-Angle, 25 Positions
In a right-angle configuration, the connector body sits flush to the PCB surface, so the z-height budget is driven by the mating receptacle's stack height, not the header itself. Compared to a vertical through-hole header of the same series, the right-angle version routes the cable or board-to-board interconnect parallel to the PCB. This is the preferred orientation when the enclosure depth is tight or when the mating harness must run along the board plane.
The part is RoHS compliant and lead-free per the manufacturer's declaration.
