For repeated field-service mating, a thicker gold (15 µinch or more) would be specified. The post finish is tin, standard for solder-joint reliability with the SMT reflow process.
At 1.25 mm pitch, the board layout needs a trace width and spacing that fits between adjacent pads — typically 0.3 mm traces with 0.25 mm clearance on a standard 1 oz copper layer.
The mating pitch is 0.049" (1.25 mm). This is the centre-to-centre spacing between adjacent pins, which determines the PCB footprint and the minimum trace routing density.
Yes, it carries ROHS3 compliance.
