USB 2.0 Type-A Receptacle, 4 Contacts, Right-Angle Board Lock
It sits in the 87520 series as a white, single-port, unshielded jack with a horizontal orientation — the standard footprint for a downstream USB host port on a motherboard or peripheral card.
The contacts carry a Gold, GXT™ finish — Amphenol's proprietary palladium-nickel alloy with a thin gold flash. GXT is harder than straight gold, so it wears through the flash layer more slowly in high-cycle applications. For a public kiosk or test fixture that sees thousands of insertions, the black-housing sibling 87520-1010BLF bumps the cycle rating to 5000 — same footprint, same GXT finish, just a different colour and a heavier-duty contact beam.
Current Rating and USB 2.0 Compliance
Rated 3 A per contact, this connector exceeds the USB 2.0 high-power spec.
Through-hole, right-angle mounting with a horizontal orientation places the USB port parallel to the board surface — typical for edge-mounted connectors on a PC motherboard or a hub card. The board lock is a pair of solder tabs that extend through the PCB and get soldered in the same wave process as the signal pins. They take the mechanical strain off the 4 signal pins during cable insertion, which is the common failure mode on unshielded right-angle USB jacks. The white insulation colour is the standard for unshielded USB receptacles — black housings (like the 87520-1010BLF) are also available but carry no functional difference beyond colour.
