Through-hole mounting gives this header stronger mechanical anchorage than surface-mount alternatives — important when the mated cable assembly will be handled or routed near the board edge. As an unshrouded breakaway header, it mates with Molex KK254 crimp receptacle housings (series 6471, 2695, and others) that accept 22-30 AWG terminals. The 0.100" pitch also matches common IDC socket strips and BergStik-compatible receptacles, widening the cross-shop options. The style is listed as Board to Board or Cable, meaning it can interconnect two PCBs or serve as the board-side half of a wire-to-board harness.
ROHS3 compliant and lead-free per current EU directives.
