The gold contact finish supports the 10,000 mating cycle rating — that cycle life is well above the typical 5,000-10,000 cycles for a standard micro USB connector, making this part suited for devices that see frequent plug/unplug duty like handheld test equipment, data loggers, or industrial control panels where the USB port is used for daily configuration downloads. ## Mounting and Board Layout This receptacle mounts via a board cutout with surface-mount solder tails — the mid-mount feature means the connector body sits at a specific height relative to the PCB edge, so the board cutout dimensions and the connector's locating pegs must match the footprint exactly. The solder retention feature adds extra hold-down tabs that get soldered to the board to resist shear forces from cable insertion and removal. Unshielded, so no metal shell to ground; the steel, stainless shell material is for mechanical retention only, not EMI containment. ## Current Rating — What the Numbers Mean The current rating is listed as 0.5A, 1A, 1.8A — this likely reflects derating by pin or by duty cycle. In a USB micro B connector, the VBUS pin (pin 1) carries the bulk of the current, while the signal pins handle far less. The 1.8A figure is probably the maximum for the power pin alone under continuous DC, with the lower figures representing per-contact limits when multiple pins carry current simultaneously.","metaTitle":"JST UB-MC5BR3-M04-4S-TB NMP USB Micro B Receptacle, Obsolete","metaDescription":"JST UB-MC5BR3-M04-4S-TB NMP is an obsolete USB micro B receptacle, 5 contacts, 10,000 mating cycles, horizontal mid-mount SMT.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["USB, Type-C & HDMI Connectors"],"specifications":{"Mfr":"JST Sales America Inc.","Gender":"Receptacle","Series":"UB","Package":"Tape & Reel (TR)","Features":"Solder Retention","Shielding":"Unshielded","Termination":"Solder","Mating Cycles":"10000","Mounting Type":"Board Cutout, Surface Mount","Connector Type":"USB - micro B","Contact Finish":"Gold","Product Status":"Obsolete","Specifications":"-","Number of Ports":"1","Voltage - Rated":"30VAC/DC","lifecycle_stage":"unknown","Insulation Color":"Black","Mounting Feature":"Horizontal, Mid Mount","Ingress Protection":"-","Number of Contacts":"5","Current Rating (Amps)":"0.5A, 1A, 1.8A","Operating Temperature":"-30°C ~ 85°C","Shell/Shielding Material":"Steel, Stainless","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5f2e43110810953790149f8004f95b1c.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/UB-MC5BR3-M04-4S-TB%20NMP/alternatives.json"},"ai":{"faq":[{"question":"Is UB-MC5BR3-M04-4S-TB NMP obsolete?","answer":"Yes, JST lists this part as obsolete."},{"question":"Where can I buy UB-MC5BR3-M04-4S-TB NMP?","answer":"This obsolete part is sourced to order against RFQ through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/jst/UB-MC5BR3-M04-4S-TB-NMP","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/jst/UB-MC5BR3-M04-4S-TB-NMP when reusing this data.
