It carries 4 contacts in a single row, shielded inside a copper-alloy shell, and is rated for USB 2.0 signaling. Contact finish is gold or gold-palladium — both grades handle the 1500-cycle duty without fretting corrosion at the USB signal level.
Lifecycle and Sourcing — 787924-3 Is Obsolete
The 787924-3 is listed as Obsolete. If you are maintaining a legacy assembly that uses this connector, the 1500-cycle rating means the receptacle itself is rarely the wear-out point — the mating cable plug typically fails first. Stock up on the mating half while sourcing the board-side part.
Right-angle through-hole solder termination — the four signal pins plus the two shell ground legs go into the PCB. The shielded shell's ground legs carry chassis ground and should connect to a low-impedance ground plane to keep the USB 2.0 signal path clean. Mates with any standard USB Type-B plug. No keying or polarization to check — the USB-B shape is asymmetrical and only goes in one way. The 4 contacts are the standard D+, D-, VBUS, and GND lines for USB 2.0.
