What this USB-A receptacle brings to a board design
What separates it from a standard USB-A jack is the 1500 mating cycles, backed by gold GXT plating on the contacts — that cycle count is roughly three times what you get from a commodity USB connector, so it suits a panel or enclosure face that sees regular plug/unplug duty over the product's life. Rated 2.5 A per contact, which is the USB 2.0 spec maximum for power delivery, and the shielded shell with copper alloy construction keeps EMI contained in the enclosure.
Board lock and right-angle mount — what that means for assembly
Without the board lock, the connector can tilt or the signal pins can crack under the lever action of a stiff USB cable. The white insulation colour is standard for USB 2.0; it helps visual inspection confirm the right speed grade on the line.
Mating cycles and contact plating — the durability story
The 1500 mating cycles is the headline durability spec. Standard USB-A receptacles are often rated 500 to 1000 cycles; this one doubles or triples that because of the gold GXT plating. GXT is Amphenol FCI's enhanced gold-over-nickel finish — it resists the fretting wear that eventually exposes the base copper and raises contact resistance. For a product that lives behind a panel door or on a test fixture where the cable gets plugged in daily, that cycle margin means the connector outlasts the product warranty without intermittent contact issues.
