Both share the same pinout and basic electrical characteristics, so the LM2903HYDT can replace an LM393 in a socket that requires higher temperature tolerance, but the reverse is not recommended for hot environments."},{"question":"Does LM2903HYDT work as a direct replacement for LM293?","answer":"Yes, the LM2903HYDT is pin-compatible with the LM293 and shares the same dual open-collector output architecture. The key difference is the extended temperature range: the LM2903HYDT is rated to 150°C versus the LM293's 125°C typical limit. In a socket that already sees junction temperatures above 125°C, the LM2903HYDT is the safer drop-in."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/LM2903HYDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/LM2903HYDT when reusing this data.
