The housing is polybutylene terephthalate (PBT) / polyester, and the part includes a board lock and keyed orientation to prevent mis-mating. The Cat3 rating limits this jack to voice-grade and low-speed data applications. It is not rated for Cat5e. No direct replacement is listed. ## Mechanical Fit and Termination Checklist This is a vertical through-hole jack with solder termination — it mounts perpendicular to the PCB and requires no right-angle routing. The board lock provides additional mechanical retention during reflow and against cable strain. The keyed housing ensures the plug inserts in one orientation only. It is unshielded and does not contain an LED.","metaTitle":"TE Connectivity 555799-1 RJ45 Jack, 8p8c, Cat3, Obsolete","metaDescription":"TE Connectivity 555799-1 RJ45 jack, 8p8c (8 position 8 contact), Cat3 rated, vertical through-hole, gold 50.0µin contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Modular / RJ Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Tray","Ratings":"Cat3","Features":"Board Lock, Keyed","LED Color":"Does Not Contain LED","Shielding":"Unshielded","Orientation":"Vertical","Termination":"Solder","Mounting Type":"Through Hole","Tab Direction":"User Selectable","Connector Type":"Jack","Contact Finish":"Gold","Number of Rows":"1","Product Status":"Obsolete","Number of Ports":"1","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Housing Material":"Polybutylene Terephthalate (PBT), Polyester","Ingress Protection":"-","Base Product Number":"555799","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":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/c5511e138250c4638c14e0e90c9f92d8.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/555799-1","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/555799-1 when reusing this data.
