Pin-compatible in the same 8-SOIC footprint. The LM431AIM carries a ±2.2% tolerance; TL431 variants typically offer 1% or 2% grades. Check the specific tolerance your design requires before substituting."},{"question":"What is LM431AIM's listed tolerance?","answer":"The LM431AIM is specified with a ±2.2% tolerance on the reference voltage. This is a general-purpose grade; for tighter regulation, a series reference like the LM4132AMF-4.1/NOPB (±0.05%) would be a closer fit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM431AIM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM431AIM when reusing this data.
