The single-row, single-port design uses gold-plated phosphor bronze contacts with a 49.3µin (1.25µm) thickness, which gives it decent mating-cycle durability for a legacy part. The housing is glass-filled nylon (PA), and the connector includes panel stops for alignment during installation. ## Lifecycle Status — Obsolete The 188728-1 is officially listed as Obsolete. This jack mounts through-hole from the bottom of the PCB — the connector body sits on the solder side, and the mating face is accessible from the top. The vertical orientation means the cable plugs in perpendicular to the board. Solder termination is standard for the eight contacts. Panel stops on the housing help locate the part during assembly, but there are no board locks or additional retention features — the solder joints carry all the mechanical load, so the board should be well-supported in the panel cutout.","metaTitle":"TE Connectivity 188728-1 RJ45 Jack, 8p8c, Cat3, Obsolete","metaDescription":"TE Connectivity 188728-1 RJ45 jack, 8p8c (8 position), Cat3 rated, vertical through-hole bottom-entry, gold-plated 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":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"Cat3","Features":"Panel Stops","LED Color":"Does Not Contain LED","Shielding":"Unshielded","Orientation":"Vertical","Termination":"Solder","Mounting Type":"Through Hole, Bottom Entry","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":"Polyamide (PA), Nylon, Glass Filled","Ingress Protection":"-","Base Product Number":"188728","Operating Temperature":"-","Contact Finish Thickness":"49.3µin (1.25µm)","Number of Positions/Contacts":"8p8c (RJ45, Ethernet)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/a728a6986b5763c38a88d190588077eb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 188728-1 obsolete?","answer":"Yes, TE Connectivity 188728-1 is listed as Obsolete.
