It carries 8 contacts in a single row, arranged per the T568A/B pinout common to 10BASE-T and 100BASE-TX installations. ## Unshielded — No EMI/RFI Protection This jack is unshielded (no metal shell or grounding tabs), so it does not provide electromagnetic or radio-frequency interference containment. It is suited for environments where conducted or radiated noise is not a concern — office LAN drops, internal equipment wiring, or control networks inside a grounded metal cabinet. For industrial floors, motor drives, or wireless base stations, a shielded RJ45 jack (with a metal shroud and drain wire connection) would be the correct choice. ## Gold Contacts for Repeated Mating Cycles The phosphor bronze spring temper maintains normal force on the RJ45 plug's tines over the connector's lifetime. ## Board Guide and Keying for Alignment The housing includes a board guide and keying features. The board guide aligns the jack to the PCB during through-hole insertion, which prevents bent pins when the part is loaded into a wave-solder fixture. The keying ensures the RJ45 plug mates in the correct orientation — the tab on the plug latch engages the housing slot, so it cannot be inserted upside down.","metaTitle":"TE Connectivity 5557804-1 RJ45 Jack, 8p8c, Unshielded","metaDescription":"TE Connectivity 5557804-1 RJ45 jack, 8p8c (8 position), unshielded, right-angle, through-hole solder, gold 50.0µin contacts.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Modular / RJ Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Series":"-","Package":"Tray","Ratings":"Cat3","Features":"Board Guide, Keyed","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":"Polyamide (PA), Nylon","Ingress Protection":"-","Base Product Number":"5557804","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":"$3.0557","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/64fb259070c0a29ff8210e57281e7824.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/5557804-1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 5557804-1 and how do I get a price?","answer":"The 5557804-1 is available to order through independent distribution.
