It sits in TE's standard modular jack family, terminated via right-angle surface-mount solder tails. The unshielded plastic housing and Cat3 frequency rating (16 MHz) make this part suited for basic voice and low-speed data applications — think telephone line interfaces, PBX equipment, or legacy data terminals — rather than modern Ethernet where Cat5e or higher is required. Two ports in a single right-angle SMT package means one component handles two line connections, saving board space versus two separate jacks. The 6p6c contact layout accepts standard 6-position modular plugs with 2, 4, or 6 conductors — common for single-line (RJ11) or two-line (RJ14) phone service. Gold-plated contacts (50.0 µin over copper alloy) resist corrosion in indoor environments where repeated plugging cycles are expected. Board locks and panel stops on the housing provide mechanical retention during reflow soldering and set a consistent standoff height from the PCB surface. ## What the Cat3 Rating Means for Your Application The Cat3 rating limits this jack to 16 MHz signal bandwidth — fine for analog voice and 10BASE-T Ethernet at 10 Mbps, but not for 100BASE-TX (100 Mbps) or faster networks that require Cat5e or higher. If the circuit expects Gigabit Ethernet, look for a shielded Cat5e or Cat6 jack instead.","metaTitle":"TE Connectivity 5406903-1 Modular Jack, 6p6c, 2-Port","metaDescription":"TE Connectivity 5406903-1 modular jack, 6p6c (RJ11/RJ12/RJ14/RJ25), 2-port, right-angle SMT, unshielded, Cat3 rated.
