This is the primary reason to choose this jack over an unshielded version in equipment like routers, switches, or factory-floor controllers where cable-borne noise can couple into the signal pair. ## Mechanical Retention and Assembly The right-angle tab-down orientation means the jack body sits flush against the PCB, with the RJ plug entering parallel to the board — a common layout for rear-panel I/O on a card-edge. The Cat3 rating indicates it meets the performance requirements for voice and basic data transmission up to 16 MHz — fine for analog phone lines, ISDN, or low-speed Ethernet, but not for 100BASE-TX or higher.","metaTitle":"TE Connectivity 5555140-2 Modular Jack, 6p4c RJ11/RJ14","metaDescription":"TE Connectivity 5555140-2 modular jack, 6p4c (RJ11/RJ14), right-angle, shielded, gold-plated contacts, board lock, panel stops, -40°C to 85°C.","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, Panel Stops","LED Color":"Does Not Contain LED","Shielding":"Shielded, EMI Finger","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":"5555140","Operating Temperature":"-40°C ~ 85°C","Contact Finish Thickness":"50.0µin (1.27µm)","Number of Positions/Contacts":"6p4c (RJ11, RJ14)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7600","priceTiers":[{"qty":1,"price":"$1.76000","currency":"USD"},{"qty":10,"price":"$1.60900","currency":"USD"},{"qty":25,"price":"$1.56120","currency":"USD"},{"qty":152,"price":"$1.43447","currency":"USD"},{"qty":304,"price":"$1.41072","currency":"USD"},{"qty":1064,"price":"$1.14918","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/b4b0b519d2f5a1d45eee47daa0cbc203.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/5555140-2/alternatives.json"},"ai":{"faq":[{"question":"Does 5555140-2 have RoHS compliance?","answer":"Yes, it is RoHS Compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5555140-2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/5555140-2 when reusing this data.
