The TE Connectivity 1775855-1 is a right-angle modular jack from the A-RJ45 series that combines an 8p8c RJ45 Ethernet port with a USB A connector in a single shielded body — a space-saving solution for equipment that needs both wired network and USB connectivity on one board footprint. The 8p8c (RJ45, Ethernet) contacts handle standard Ethernet signals, while the integrated USB A jack provides a second data or power interface. The shielded shell (Shielded) reduces EMI coupling to the Ethernet pair, important for maintaining signal integrity in industrial panels, network switches, or embedded systems near switching power supplies.
Through-hole mounting (Through Hole) with solder termination (Solder) gives the connector a mechanically robust attachment that withstands repeated mating cycles without lifting pads — a common failure mode for SMT jacks under cable strain. The tab direction is Up (Tab Direction), which orients the RJ45 latch opening upward relative to the PCB plane; confirm this matches the enclosure cutout and cable plug entry angle.
Contact and Material Construction
Contacts are phosphor bronze (Contact Material) with a gold flash finish (Contact Finish Thickness: Flash) on the mating surface. Gold flash provides corrosion resistance and adequate cycle life for typical Ethernet reconnections — think patch-panel duty, not high-cycle field reconnects. The housing is glass-filled PBT (Polybutylene Terephthalate (PBT), Glass Filled), a dimensionally stable material that holds the contact alignment through reflow and wave-solder profiles. The package is Tray (Package), which is standard for through-hole jacks of this size.
