The ±2.2% tolerance on the internal reference voltage suits general-purpose regulation where tighter grades (0.5% or 1%) are not required. For industrial or automotive environments, the TL431C or TL431I family members with extended temperature ranges would be the correct choice. Any remaining stock in the supply chain is finite and typically sourced through independent distributors or surplus channels. The TL431 family includes many active variants in the same SOT-23-5 package with identical pinout — the key difference is the temperature grade and tolerance grade. Because the TL431CDBVRE4 is obsolete, any procurement for this exact order code will be fulfilled from existing surplus or broker inventory. ## Package and footprint — SOT-23-5 layout notes The TL431CDBVRE4 is supplied in a SOT-23-5 package (also designated SC-74A).","metaTitle":"TL431CDBVRE4 Adjustable Shunt Reference, 2.495V, SOT-23-5","metaDescription":"Texas Instruments TL431CDBVRE4 adjustable shunt voltage reference. 2.495V min output, 36V max, 100 mA cathode current, ±2.2% tolerance, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±2.2%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"1 mA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"0°C~70°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431CDBVRE4/alternatives.json"},"ai":{"faq":[{"question":"Is TL431CDBVRE4 obsolete?","answer":"Yes, Texas Instruments has classified the TL431CDBVRE4 as Obsolete."},{"question":"What is the replacement for TL431CDBVRE4?","answer":"Verify the tolerance and temperature grade match your application before substituting."},{"question":"Does TL431CDBVRE4 have RoHS or lead-free compliance?","answer":"The evidence does not explicitly state RoHS or lead-free compliance for this order code.
