The 1 A current rating per contact is adequate for the VBUS power line in standard USB 2.0 applications, including OTG devices where the port may supply or sink power. ## Compliance and Operating Range Rated for 0°C to 50°C operating temperature, the connector is intended for indoor consumer and commercial electronics rather than extended-temperature industrial environments. ROHS3 compliance is confirmed.","metaTitle":"Molex 513870578 USB Mini B Receptacle, 5 Contacts, Shielded","metaDescription":"Molex 513870578 USB 2.0 mini B receptacle, 5 contacts, shielded, SMT right-angle mount, gold contacts, rated 1A at 30VAC/DC.","metaKeywords":null},"attributes":{"series":"51387","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["USB, Type-C & HDMI Connectors","USB / HDMI Cable Assemblies"],"specifications":{"Gender":"Receptacle","Series":"51387","Package":"Tape & Reel (TR); Cut Tape (CT)","Shielding":"Shielded","Termination":"Solder","Mounting Type":"Surface Mount, Right Angle; Through Hole","Connector Type":"USB - mini B","Contact Finish":"Gold","Product Status":"Active","Specifications":"USB 2.0 OTG","Number of Ports":"1","Voltage - Rated":"30VAC/DC","lifecycle_stage":"unknown","Insulation Color":"Black","Mounting Feature":"Horizontal","Number of Contacts":"5","Base Product Number":"051387","Current Rating (Amps)":"1A","Operating Temperature":"0°C ~ 50°C","Shell/Shielding Material":"Copper Alloy","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.67","stockQuantity":20,"priceTiers":[{"qty":1,"price":"$1.67000","currency":"USD"},{"qty":10,"price":"$1.42400","currency":"USD"},{"qty":100,"price":"$1.17650","currency":"USD"},{"qty":1000,"price":"$0.92885","currency":"USD"},{"qty":2000,"price":"$0.89789","currency":"USD"},{"qty":3000,"price":"$0.86692","currency":"USD"},{"qty":5000,"price":"$0.82358","currency":"USD"},{"qty":10000,"price":"$0.80500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/fbb09e5db6ecc4f2b2efcc4940f5664a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the 513870578 compatible with USB OTG (On-The-Go) devices?","answer":"Yes, the connector is specified for USB 2.0 OTG, which means it supports the host/peripheral negotiation protocol used in OTG devices like smartphones and tablets."},{"question":"Is the 513870578 shielded?","answer":"Yes, the connector is shielded with a copper alloy shell, which provides EMI containment and noise rejection for the USB data lines."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/513870578","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/molex/513870578 when reusing this data.
