USB-A and Power Combo Receptacle — Board-Edge Fit
The Amphenol FCI 55917-801LF is a shielded USB-A (USB TYPE-A) and power combo receptacle, integrating eight contacts in a single right-angle through-hole package. It sits in the 55917 series as a 1-port, horizontal-mount connector designed for board-edge applications where a combined data and low-current power interface is needed. The teal insulation color and board lock features are visual and mechanical identifiers for this specific variant. Rated for USB 2.0 signaling and 5 A at 12 V across the power contacts. The 1500 mating cycles rating indicates the gold GXT™ contact finish is specced for repeated connect-disconnect cycles.
This is a receptacle — it mates with a USB-A plug and a separate power plug (or a combined cable assembly designed for this combo interface). The 8 contacts break down as 4 standard USB-A signal/ground contacts plus 4 power contacts, though the exact pinout should be verified against the product drawing for the mating half. Termination is solder — through-hole tails for the signal and power contacts plus the board lock posts. The shielded shell is copper alloy, grounded through the PCB ground plane via the shield legs.
