The 0026481032: Unshrouded, so the pins are exposed after soldering; mates with KK396 crimp housings or IDC receptacles. The 0.573" (14.55mm) mating pin length gives good insertion depth into the receptacle. In a build-to-print harness that sees fewer than 25 mate-unmate cycles over its life, tin is the right call — gold would be over-spec.
The 3.96mm pitch and single-row layout require a matching 3-position KK396 receptacle housing (e.g., Molex 41662 series) with 0.156" centerline. The square pin profile (0.045" typical for KK396) provides good solder fillet formation and pull-out strength.
ROHS3 compliant and UL94 V-0 rated.
