This is the jack you spec when the panel needs a visual link status and the cable run is Cat3 voice or low-speed data. ## What Cat3 Rating Means for Your Application The Cat3 rating sets the frequency ceiling at 16 MHz — fine for 10BASE-T Ethernet and analog phone lines, but not for 100BASE-TX Fast Ethernet (which needs Cat5 at 100 MHz) or gigabit. For a legacy PBX, an intercom system, or a 10 Mb control network, it's a direct fit. The shielded construction helps keep coupled noise off the signal pair in industrial cabinets where VFDs or contactors share the panel. ## Green LED and Board Lock — Practical Details The green-green LED pair means both indicator positions light green when the link is active — no bicolor or amber. If the existing jack in the panel has a green-yellow or green-amber LED, the 1-1734577-4 won't match the blink pattern. The board lock is a pair of plastic pegs that snap into the PCB before reflow or wave solder, keeping the jack square to the board while the solder joints set. On a production line that's a reliability win; in a rework station it means you need to clear the holes before inserting the replacement. The 1-1734577-4 shares the same shielded vertical body, Cat3 rating, and board lock as the 1734577-4 — the difference is the LED: green-green here versus green-yellow on the 1734577-4. If the BOM specifies a board lock and thick gold for repeated reconnects, the 1-1734577-4 or 1734577-4 are the ones; the 1734577-2 is a cost-reduced variant for single-mate installs.","metaTitle":"TE 1-1734577-4 Cat3 RJ45 Jack, Shielded, Green LED","metaDescription":"TE Connectivity 1-1734577-4 modular jack, 8p8c (RJ45), Cat3 rated, shielded, vertical through-hole, gold contacts, green LED.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Modular / RJ Connectors","Modular Jacks (RJ)"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Tray","Ratings":"Cat3","Features":"Board Lock","LED Color":"Green - Green","Shielding":"Shielded","Orientation":"Vertical","Termination":"Solder","Mounting Type":"Through Hole","Tab Direction":"User Selectable","Connector Type":"Jack","Contact Finish":"Gold","Number of Rows":"1","Product Status":"Active","Number of Ports":"1","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Housing Material":"Polyamide (PA46), Nylon 4/6, Glass Filled","Ingress Protection":"-","Base Product Number":"1734577","Operating Temperature":"-","Contact Finish Thickness":"50.0µin (1.27µm)","Number of Positions/Contacts":"8p8c (RJ45, Ethernet)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.49000","currency":"USD"},{"qty":10,"price":"$3.93100","currency":"USD"},{"qty":25,"price":"$3.82800","currency":"USD"},{"qty":100,"price":"$3.51920","currency":"USD"},{"qty":300,"price":"$3.49863","currency":"USD"},{"qty":500,"price":"$3.27224","currency":"USD"},{"qty":1000,"price":"$2.92238","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5f75512d2354e0bebc5c9942c703925e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1-1734577-4?","answer":"The 1-1734577-4 is sourced to order through independent distribution.
