The Molex 676432911 is a standard USB-A (USB Type-A) receptacle from the 67643 series, with 4 contacts in a single port. It is a right-angle through-hole mount part, designed to sit horizontally on the PCB edge — the orientation that lets a USB cable plug in parallel to the board surface. This is the typical layout for rear-panel I/O on desktop PCs, industrial control panels, test equipment, and consumer electronics enclosures where the PCB runs parallel to the chassis wall. The shell is soldered to the board through multiple ground tabs, not just the signal pins. Board locks on the mounting tabs anchor the connector against the mechanical stress of repeated cable insertions and removals. Without those locks, the solder joints on the signal pins take the full shear load and can crack over the connector's service life.
Ratings that drive the fit decision
Rated 1.5A per contact at 30VDC. For high-cycle applications (kiosks, public terminals), a thicker gold or a different contact system would be specified. The UL94 V-0 housing means the connector can be used in equipment that requires a flame-retardant enclosure rating — a common requirement for commercial and industrial products sold into regulated markets.
