Substitute Part Grouping Explanation
Substitution for the MAX901ACSE is determined by strict equivalence across the following critical parameters:
- Number of comparator elements: 4
- Output type: TTL
- Package type: 16-SOIC surface mount
- Supply voltage range: 5V ~ 10V, ±2.5V ~ 5V
- Input offset voltage: 2mV @ ±5V
- Input bias current: 6µA @ ±5V
- Quiescent current specifications: 15mA, 12mA, 6mA
- CMRR and PSRR: 86.02dB
- Operating temperature range: 0°C ~ 70°C
- Compliance certifications: ROHS3, REACH Unaffected
The MAX901ACSE+ meets all these criteria and serves as a direct functional equivalent with identical electrical and mechanical specifications.

Engineering Selection Recommendations
The MAX901ACSE+ is the active equivalent for the obsolete MAX901ACSE. Both parts maintain identical electrical specifications, package geometry, and compliance certifications. The MAX901ACSE+ is currently in active production status with confirmed inventory availability. Selection of the MAX901ACSE+ ensures continuity of supply and maintains full compatibility with existing designs specified for the MAX901ACSE. Both parts satisfy ROHS3 compliance and REACH regulatory requirements.
Frequently Asked Questions (FAQ)
Q: Can the MAX901ACSE+ be used as a direct replacement for the MAX901ACSE?
A: Yes. The MAX901ACSE+ is electrically and mechanically identical to the MAX901ACSE. All electrical parameters, package dimensions, and pin configurations are equivalent. The primary difference is product status: MAX901ACSE+ is active production while MAX901ACSE is obsolete.
Q: What is the difference between MAX901ACSE and MAX901ACSE+?
A: The devices are functionally identical. The "+" designation on the MAX901ACSE+ indicates the active production variant. The MAX901ACSE+ is supplied in Tube packaging, while the original MAX901ACSE packaging specification was not provided.
Q: Are there any compliance or certification differences?
A: No. Both the MAX901ACSE and MAX901ACSE+ carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and MSL 1 (Unlimited).
Q: What are the critical parameters for substitution?
A: Substitution is valid when the following parameters match: 4-element comparator configuration, TTL output type, 16-SOIC package, 5V ~ 10V / ±2.5V ~ 5V supply voltage range, 2mV input offset, 6µA input bias current, and 0°C ~ 70°C operating temperature.
Q: Is the MAX901ACSE+ available in the same package?
A: Yes. The MAX901ACSE+ uses the same 16-SOIC (0.154", 3.90mm Width) surface-mount package as the MAX901ACSE.
