Stacked Dual-Port USB-A Receptacle for Board-Edge Mounting
The TE Connectivity 5787745-4 is a stacked USB-A (USB TYPE-A) receptacle housing two USB 2.0 ports in a single right-angle through-hole package. The 1500 mating cycles exceed typical consumer USB connectors. Contact finish is gold or gold-palladium, which resists corrosion and maintains signal integrity over the 1500-cycle life.
Board Lock and Mechanical Retention
The integrated board lock provides a positive mechanical anchor to the PCB through the solder joints. On a right-angle connector that sees lever forces from cable insertion, the board lock prevents the solder tails from cracking over repeated mate cycles — a common failure point on unsecured right-angle USB ports.
Mating Cycle Life and Field Service
The gold or gold-palladium contact finish supports this cycle life by resisting contact fretting and oxidation that would increase resistance over time.
