The Molex 0875310001 is a USB-A (USB Type-A) receptacle from the 87531 series, offering two stacked ports with a total of 4 contacts — the standard USB 2.0 pinout. The shielded shell is made from copper alloy, and the contacts are gold-plated for corrosion resistance over repeated mating cycles.
Rated 1A per contact at 30V, this connector follows the USB-A pin assignment (VBUS, D-, D+, GND). The through-hole right-angle mounting requires a board cutout or edge placement. The operating temperature range of 0°C to 40°C limits this connector to indoor, climate-controlled environments — not suitable for automotive or outdoor use without additional thermal management. The gold contact finish supports the standard 1,500 mating cycle rating typical for USB-A receptacles, making it reliable for field-service connections.
