It is the unshielded, right-angle through-hole member of the 5555979 series, with a single row of gold-plated phosphor bronze contacts rated for Cat3 performance — the standard for voice and low-speed data up to 16 MHz. Through-hole solder tails provide stronger mechanical retention than SMT for a connector that sees frequent mating cycles. The tab direction is down, which orients the latch slot toward the board surface. The board lock is a pair of plastic or metal posts that snap into plated through-holes, holding the jack in place during the solder wave and preventing the connector from lifting under cable strain. For a part with no LED and no shielding, the board lock is the primary mechanical retention feature. The 5555979-1 is an active TE Connectivity catalog item, sourced through independent distribution.","metaTitle":"TE Connectivity 5555979-1 Modular Jack, 6P4C RJ11/RJ14","metaDescription":"TE Connectivity 5555979-1 modular jack, 6P4C (RJ11/RJ14), right-angle through-hole, unshielded, gold-plated contacts, board lock, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 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":"5555979","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":"$1.8000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.80000","currency":"USD"},{"qty":10,"price":"$1.64600","currency":"USD"},{"qty":25,"price":"$1.59760","currency":"USD"},{"qty":150,"price":"$1.46793","currency":"USD"},{"qty":300,"price":"$1.44360","currency":"USD"},{"qty":1050,"price":"$1.17596","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/838e82806b60363a2c63b4d78c9cbd28.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the specifications of the 5555979-1 modular jack?","answer":"It is rated Cat3 for voice and low-speed data."},{"question":"Does the 5555979-1 have an LED indicator or shielding?","answer":"No. This jack does not contain an LED and is unshielded.
