Substitute Part Grouping Explanation
Substitution eligibility for the MAX9107ESA is determined by strict equivalence across the following critical parameters:
- Package type and physical dimensions (8-SOIC, 0.154" width, 3.90mm)
- Surface mount mounting technology
- Dual-element comparator configuration (2 channels)
- TTL output logic family
- Supply voltage range (4.5V ~ 5.5V)
- Electrical performance specifications (input offset, bias current, quiescent current, propagation delay, hysteresis)
- Operating temperature range (-40°C ~ 85°C)
- Regulatory compliance (RoHS3, REACH)
The MAX9107ESA+ qualifies as a direct substitute based on complete parameter alignment across all electrical, mechanical, and regulatory criteria.

Engineering Selection Recommendations
The MAX9107ESA+ is a direct functional equivalent to the MAX9107ESA. The primary distinction is product status: the MAX9107ESA is obsolete while the MAX9107ESA+ maintains active production status. Both devices are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The MAX9107ESA+ is supplied in tube packaging, whereas the original part number does not specify packaging format in the provided data.
For new designs and ongoing production requiring dual general-purpose TTL comparators in 8-SOIC packages, the MAX9107ESA+ is the appropriate selection due to its active availability and identical electrical specifications.
