The full shield is made of copper alloy and wraps the contact area, providing EMI containment for the USB 2.0 differential pair — important when the port is on a noisy digital board or near a switching power supply. Thin flash plating would wear through in a few hundred cycles, exposing the base metal and raising contact resistance. At 1500 cycles, this receptacle is built for field-serviceable equipment or lab instruments where the cable is plugged and unplugged regularly, not for a one-time factory harness. ## USB 2.0 vs USB 3.0 — Know the Spec Limit It is not electrically or mechanically compatible with USB 3.0 or 3.1 Type-B connectors, which use a different contact arrangement and additional high-speed differential pairs. If your design requires SuperSpeed data transfer, this is the wrong connector. For standard USB 2.0 peripheral ports — printers, scanners, external drives, data acquisition modules — it is a direct fit.","metaTitle":"61729-1011RLF USB-B Receptacle, 4 Contacts, Shielded","metaDescription":"FCI 61729-1011RLF USB-B receptacle, 4 contacts, USB 2.0, shielded, board lock, through-hole right-angle, gold contacts, 1500 mating cycles, UL94 V-0.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["USB, Type-C & HDMI Connectors"],"specifications":{"Gender":"Receptacle","Series":"61729","Features":"Board Lock","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Shielding":"Shielded","Part Status":"Active","Termination":"Solder","Manufacturer":"Amphenol ICC (FCI)","Mating Cycles":"1500","Mounting Type":"Through Hole, Right Angle","Connector Type":"USB-B (USB TYPE-B)","Contact Finish":"Gold","Specifications":"USB 2.0","Number of Ports":"1","Voltage - Rated":"-","lifecycle_stage":"unknown","Insulation Color":"Black","Mounting Feature":"Horizontal","Ingress Protection":"-","Number of Contacts":"4","Base Product Number":"61729","Current Rating (Amps)":"1A","Operating Temperature":"-55°C ~ 85°C","Shell/Shielding Material":"Copper Alloy","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4100","stockQuantity":17,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/2b918e9899140055f7100f761f5ffcd6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does 61729-1011RLF have a board lock?","answer":"Yes, the 61729-1011RLF includes a board lock feature that anchors the shell to the PCB through a plated through-hole, providing mechanical retention against plug insertion forces."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/amphenol/61729-1011RLF","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/amphenol/61729-1011RLF when reusing this data.
