The 55917-900LF: The 1500 mating cycles rating is double the typical USB-A receptacle, which means this connector was designed for repeated field-service or test-equipment use where the port sees frequent connect/disconnect. The through-hole right-angle mounting with board lock anchors the connector against the shear force from cable insertion and removal, which is the main mechanical stress on a USB port.
