The right-angle orientation places the jack parallel to the PCB, common for edge-mounted Ethernet ports in industrial controllers, telecom equipment, and building automation panels. The Cat3 rating sets the frequency ceiling at 16 MHz — this jack is not rated for Cat5e (100 MHz) or higher Ethernet standards. For 10BASE-T, voice, or RS-232 over twisted pair, the Cat3 rating is sufficient. The unshielded design (no metal shell or grounding tabs) keeps cost low in non-critical signal paths but does not provide EMI rejection; if the application runs near motors or switch-mode supplies, a shielded jack is the better call. ## Board Lock and Through-Hole Termination The board lock is a pair of through-hole retention posts that solder into the PCB alongside the signal pins. This prevents the jack from lifting off the board during cable insertion and removal — a common failure point on unsecured modular jacks. The tab direction is down, meaning the latch release faces the PCB side, which matters for enclosure clearance and cable routing. No LED is included, so status indication must come from an external source.","metaTitle":"TE Connectivity 5520243-4 Modular Jack, 8p8c RJ45, Cat3, R/A","metaDescription":"TE Connectivity 5520243-4 modular jack, 8p8c (RJ45), Cat3 rated, right-angle through-hole, unshielded, gold contacts, board lock.","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":"Does Not Contain LED","Shielding":"Unshielded","Orientation":"90° Angle (Right)","Termination":"Solder","Mounting Type":"Through Hole","Tab Direction":"Down","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":"Polybutylene Terephthalate (PBT), Polyester","Ingress Protection":"-","Base Product Number":"5520243","Operating Temperature":"-40°C ~ 85°C","Contact Finish Thickness":"50.0µin (1.27µm)","Number of Positions/Contacts":"8p8c (RJ45, Ethernet)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.69000","currency":"USD"},{"qty":10,"price":"$3.28400","currency":"USD"},{"qty":25,"price":"$3.26720","currency":"USD"},{"qty":136,"price":"$2.91537","currency":"USD"},{"qty":272,"price":"$2.89857","currency":"USD"},{"qty":544,"price":"$2.68077","currency":"USD"},{"qty":2448,"price":"$2.39594","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4a75c114f74cac969ba7aca214f19ce0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the 5520243-4 have an LED indicator?","answer":"No, this jack does not contain an LED.
