The B-grade tolerance of ±0.5% makes this variant a tighter-accuracy pick over the standard ±1% or ±2% grades. ## Through-hole form factor and temperature range Housed in a TO-92-3 (TO-226AA) through-hole package, this part is suited for designs that avoid SMD assembly or where manual rework is common. For BOM lines that still specify this exact order code, the only channel is the surplus and independent market.","metaTitle":"TL431BQLPE3 Adjustable Shunt Reference, ±0.5%, TO-92-3","metaDescription":"TL431BQLPE3 adjustable shunt voltage reference, ±0.5% tolerance, 100 mA output, TO-92-3 through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Bulk","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"TO-92-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99b53f28cf28b982a16c2a9ac87cd6e9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431BQLPE3/alternatives.json"},"ai":{"faq":[{"question":"Is TL431BQLPE3 obsolete?","answer":"Yes, the TL431BQLPE3 is officially listed as Obsolete by Texas Instruments.

The TL431 family includes many active variants (e.g., TL431A, TL431B in SOT-23 or SOT-89 packages), but the exact through-hole TO-92-3 with ±0.5% tolerance may not have a direct pin-compatible drop-in.
