Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX961EUA-T is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is MAX961EUA+T, which maintains identical specifications across voltage supply range, input offset voltage, bias current, quiescent current, propagation delay, hysteresis, operating temperature, and package configuration. Both parts are classified as general-purpose comparators with single-channel architecture and identical output characteristics.

The substitution is valid based on the following criteria:

• Identical supply voltage range (2.7V ~ 5.5V)
• Matching input offset voltage specification (1.5mV @ 5V)
• Equivalent input bias current (15µA @ 5V)
• Same quiescent current rating (11mA)
• Identical propagation delay (7ns maximum)
• Matching hysteresis value (4.6mV)
• Identical operating temperature range (-40°C ~ 85°C)
• Same package type (8-TSSOP, 8-MSOP)
• Equivalent output configuration (CMOS, Complementary, TTL)

Parameter Comparison

Engineering Selection Recommendations

The MAX961EUA+T is the direct equivalent substitute for the obsolete MAX961EUA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical and mechanical specifications. The primary distinction is product status: MAX961EUA-T is obsolete while MAX961EUA+T is active and currently in production.

Selection of MAX961EUA+T is supported by:

• Full electrical parameter equivalence across all specified ratings
• Identical package configuration (8-TSSOP, 8-MSOP) ensuring direct PCB compatibility
• Matching compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Equivalent moisture sensitivity rating (MSL 1)
• Active manufacturing status ensuring supply chain availability

For applications currently using MAX961EUA-T, direct substitution with MAX961EUA+T requires no circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can MAX961EUA+T be used as a direct replacement for MAX961EUA-T?

A: Yes. Both parts are electrically and mechanically identical. The MAX961EUA+T is the active production equivalent of the obsolete MAX961EUA-T. No circuit modifications are required for substitution.

Q: What is the difference between MAX961EUA-T and MAX961EUA+T?

A: The parts are functionally identical. The difference lies in product status and packaging format. MAX961EUA-T is obsolete; MAX961EUA+T is active. MAX961EUA+T is supplied in Cut Tape (CT) and Digi-Reel® packaging, while MAX961EUA-T packaging details are not specified in the available data.
