For legacy designs or military/aerospace builds where leaded solder is still permitted or exempted, it's a straightforward drop-in. No second-source alternate is listed in the available records, so dual-sourcing would require qualification of a functionally equivalent comparator from another vendor. ## What the ratings mean for your BOM The supply voltage range is not listed in the available specs. Verify against the full datasheet.","metaTitle":"LMX393AUA Dual Comparator, Tiny-Pack, Active","metaDescription":"LMX393AUA dual tiny-pack comparator from National Semiconductor.

The core comparator function is the same — two independent comparators with open-collector outputs — but the LMX393AUA comes in a smaller footprint package, saving board area at the expense of slightly tighter layout constraints. The LM393 is typically available in larger packages like SOIC-8 or DIP-8, which are easier to hand-solder and route on a two-layer board."},{"question":"Is LMX393AUA RoHS compliant?","answer":"No, the LMX393AUA is marked as RoHS non-compliant. It contains lead and cannot be used in products requiring RoHS compliance unless an exemption applies. For RoHS-required builds, look for a lead-free comparator alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LMX393AUA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LMX393AUA when reusing this data.
