TE Connectivity 1-338084-6 — 4P4C Modular Jack, Vertical SMT
The TE Connectivity 1-338084-6 is a 4p4c (RJ9, RJ10, RJ22) modular jack in a vertical surface-mount package. It is the 4-position, 4-conductor member of the 338084 series, designed for unshielded telecom and low-speed data connections where a compact, reflow-solderable jack is needed.
Cat3 Rating and Application Fit
Rated Cat3, this jack is specified for voice-frequency applications — the 4p4c contact arrangement matches the pinout for single-line telephone handsets and similar low-bandwidth gear. The Cat3 ceiling means it is not intended for 100BASE-TX or higher data rates; for those, a Cat5e or Cat6 jack would be the correct choice. The vertical orientation and SMT termination suit it for compact PCBs where the cable enters perpendicular to the board.
SMT Termination and Solder Retention
Terminated by solder to surface-mount pads, this jack is processed in a standard reflow oven alongside other SMT components. The solder retention feature — integral to the housing — provides additional mechanical hold during the solder process and in service, reducing the risk of lifted pads from cable tug or vibration. The housing is glass-filled polyamide (PA9T, Nylon 9T), rated for the thermal profile of lead-free reflow.
