No official successor or second-source cross-reference is published, but the standard TL431BQ pin-compatible family is widely available for dual-sourcing qualification.","metaTitle":"TLV431BQDBZRQ1 Automotive Shunt Reference, ±0.5%, SOT-23-3","metaDescription":"Texas Instruments TLV431BQDBZRQ1 adjustable shunt voltage reference, AEC-Q100, ±0.5% tolerance, 1.24 V to 6 V output, -40 to 125°C, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"100 µA","Base Product Number":"TLV431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"6 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1695c8b3d8afb55e8f684e9e4463cb60.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431BQDBZRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the equivalent of TLV431BQDBZRQ1?","answer":"The standard TL431BQ (non-automotive grade) shares the same SOT-23-3 pinout and adjustable 1.24 V to 6 V output, but lacks AEC-Q100 qualification."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV431BQDBZRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV431BQDBZRQ1 when reusing this data.
