MAX974ESE-T Equivalent & Substitute Parts

Part Overview

The MAX974ESE-T is a quad comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This device features open-drain outputs and operates across a wide supply voltage range of 2.5V to 11V (single supply) or ±1.25V to 5.5V (dual supply). The component is packaged in a 16-SOIC surface-mount configuration.

The MAX974ESE-T is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this comparator architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX974ESE-T is determined by strict equivalence across the following critical parameters:

• Functional Architecture: Quad comparator with integrated voltage reference
• Output Configuration: Open-drain topology
• Supply Voltage Compatibility: 2.5V ~ 11V (single) or ±1.25V ~ 5.5V (dual)
• Electrical Performance: Input offset voltage 10mV @ 5V, quiescent current 8.5µA maximum, CMRR and PSRR at 80dB
• Package Specification: 16-SOIC surface-mount package with 0.154" width (3.90mm)
• Operating Temperature: -40°C ~ 85°C range
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The MAX974ESE+T qualifies as a direct substitute based on identical electrical specifications, package configuration, and manufacturing origin. The primary distinction is packaging format: the original part uses tube packaging, while the substitute uses tape and reel (TR) format. Both maintain full functional and electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The MAX974ESE+T is the direct substitute for the obsolete MAX974ESE-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications, functional architecture, and package configuration.

The MAX974ESE+T carries Active product status, ensuring ongoing availability and manufacturing support. Both parts meet ROHS3 compliance requirements and carry MSL Level 1 moisture sensitivity ratings, indicating no special handling requirements during storage or assembly.

The only material difference is packaging format: tube versus tape and reel. This distinction affects supply chain logistics and automated assembly compatibility but does not impact electrical performance or functional equivalence. Selection between these formats depends on production volume requirements and assembly equipment capabilities.

Frequently Asked Questions (FAQ)

Q: Can the MAX974ESE+T be used as a direct replacement for the MAX974ESE-T in existing designs?

A: Yes. The MAX974ESE+T is electrically and functionally identical to the MAX974ESE-T. Both devices feature the same quad comparator architecture with voltage reference, open-drain outputs, supply voltage range, input offset specifications, and 16-SOIC package configuration. No circuit modifications are required.

Q: What is the difference between the tube and tape & reel packaging formats?

A: Tube packaging contains loose components in a plastic tube, suitable for manual assembly or low-volume production. Tape and reel packaging presents components on a continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly equipment. Electrical and functional performance is identical between formats.

Q: Are both parts RoHS compliant?

A: Yes. Both the MAX974ESE-T and MAX974ESE+T are ROHS3 compliant and carry MSL Level 1 moisture sensitivity ratings. No special storage or handling procedures are required beyond standard component storage practices.

Q: Why is the original MAX974ESE-T classified as obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Analog Devices Inc./Maxim Integrated. The MAX974ESE+T remains in active production and provides full functional equivalence, ensuring design continuity and supply chain support for applications requiring this comparator architecture.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical specifications across all provided electrical parameters: input offset voltage, quiescent current, CMRR, PSRR, supply voltage range, and operating temperature range. Performance is equivalent in all applications.
