Its Cat3 rating means it's specced for voice and 10BASE-T Ethernet, not modern Cat5e or higher twisted-pair data rates. ## What Cat3 Means for Your Fit The Cat3 rating caps the usable signal bandwidth to 16 MHz — fine for POTS lines, RS-232 over twisted pair, or legacy 10 Mb networks. The 6p6c contact arrangement gives you six positions with six conductors; it mates with any standard 6-position RJ plug, but the centre two contacts (positions 3 and 4) are the typical tip/ring pair. Right-angle orientation places the jack parallel to the PCB, saving height in a shallow enclosure. ## Obsolete — Sourcing the 5520242-3 TE Connectivity lists the 5520242-3 as Obsolete. No official successor part number appears on record, so there's no pin-compatible drop-in from the same manufacturer. Date codes will vary; expect last-time-buy stock or pulled inventory. If you need a guaranteed long-term supply, a re-qualification to a current modular jack series is worth planning. Through-hole solder termination — no press-fit, no SMT reflow. The tab points down (board edge down), so the jack body stands perpendicular to the PCB. A board guide feature on the housing aids alignment during hand-solder or wave-solder assembly. No LED, no shielding — it's a bare, unshielded jack. The tray packaging keeps the parts oriented for pick-and-place if you're running a selective solder line.","metaTitle":"TE 5520242-3 RJ11 Jack, 6p6c, Right-Angle, Cat3, Obsolete","metaDescription":"TE 5520242-3 RJ11/RJ12 jack, 6p6c, right-angle through-hole, gold 50.0µin contacts, Cat3 rating.
