Product details

The 4-102973-0-39: The breakaway design means you can snap the header to a shorter length if your BOM doesn't need every pin.

The push-pull fastening type indicates a friction-lock interface. Termination is through-hole solder, with a 0.125" (3.18mm) post length suitable for standard PCB thicknesses. The square pins (0.025" square typical for the series) mate with standard AMPMODU receptacle contacts. The solder tails have a tin-lead finish, so confirm your assembly process is compatible with leaded solder.

The contact material is copper alloy with gold on the mating face and tin-lead on the solder posts.
