The post tails are tin-plated (2.00 µm), compatible with standard lead-free solder processes.
The 0.114" (2.90 mm) post length protrudes through the PCB for solder fillet formation.
The mating header must have 31 positions, single row, with square pins (0.025" square typical). Confirm the header's pin length and orientation (straight or right-angle) to match your board stack-up.
Yes, the LF suffix in the order code indicates lead-free / RoHS-compliant construction. The tin-plated posts and gold-plated mating contacts are compatible with RoHS assembly requirements.
