Mating Compatibility and Termination Checklist
The 58102-G61-09LF: Termination is solder to through-hole — the square pins (0.025" square typical for 2.00 mm pitch) provide a reliable solder joint with good pull strength. No press-fit or surface-mount option on this variant; the right-angle body requires the board to have plated through-holes at the correct drill diameter for the post.
Peer Comparison: 18 vs 14 Positions
The 18-position variant (58102-G61-09LF) adds one more pair of pins — useful when the BOM requires four additional signal lines without changing the connector family or footprint pitch.
