The 75757-5121: This is a Molex MX150 vertical dual-row pin header, 4 circuits total. The vertical orientation keeps the harness perpendicular to the PCB, which matters when the board edge has a tight z-height budget or the cable exits straight up into a conduit. That's the current standard for equipment sold into EU markets and most global OEMs.
