The TE Connectivity 2-338086-3 is a 6-position 6-contact (6p6c) modular jack — the keyed body accepts RJ11, RJ12, RJ14, and RJ25 plugs, covering standard single- and dual-line telephone wiring plus some low-speed data links. It sits in the 338086 base series as a vertical surface-mount variant, unshielded, with gold-plated phosphor bronze contacts that resist corrosion in indoor equipment environments. Rated Cat3, this jack is built for voice-band and 10BASE-T Ethernet at best — not for modern high-speed data. The Cat3 rating means it meets the electrical performance requirements for frequencies up to 16 MHz, which covers POTS (plain old telephone service), ISDN, and legacy 10 Mb/s networking. If the BOM calls for Gigabit Ethernet or PoE, this is the wrong part.
Mounting and Termination Details for the Board Layout
Vertical orientation means the mated plug exits straight up from the PCB — plan for cable clearance above the board. The surface-mount termination suits automated pick-and-place and reflow assembly; the Tape & Reel packaging (also available as Cut Tape) confirms this jack is intended for high-volume SMT lines, not hand-soldering. Solder retention tabs on the housing anchor the jack against the mechanical stress of plug insertion and cable tug. The housing is glass-filled PA9T nylon.
