This is a single-port receptacle, not a stacked or multi-port variant. The 1A and 1.8A current ratings reflect the standard micro-B pinout: the lower figure applies to the signal contacts (D+, D-, ID), while the higher figure covers the VBUS power contact. ## Mounting and Termination — What the SMT Vertical Mount Means for Your Board This is a surface-mount, vertical-mount receptacle. The SMT pads sit on the bottom of the board, and the connector body stands upright — the USB plug inserts from above, parallel to the board normal. The vertical orientation is common for edge-of-board or panel-mount USB ports where the cable enters perpendicular to the PCB. The Pick and Place feature means the reel packaging includes a cover tape and the part is compatible with automated placement — no hand-soldering required for volume assembly. The termination is solder-only — no press-fit option. The steel shell provides the mechanical retention to the board through its solder tabs; make sure your footprint includes the shell anchor pads, because the USB insert/withdraw force is carried by those tabs, not the signal pins. The 10,000 mating cycles is the standout spec on this part. The gold contact finish is what enables that cycle life — tin-plated contacts would wear through the plating and expose the base metal well before 10,000 mates.","metaTitle":"Molex 1051330031 USB 2.0 Micro-B Receptacle, 5 Contacts","metaDescription":"Molex 1051330031 USB 2.0 micro-B receptacle, 5 contacts, shielded, SMT, 10,000 mating cycles.
