MAX972CUA-T Equivalent & Substitute Parts

Part Overview

The MAX972CUA-T is a dual-channel general-purpose comparator with integrated voltage reference and open-drain output configuration, manufactured by Analog Devices Inc./Maxim Integrated. This device operates across a wide supply voltage range (2.5V to 11V single supply, ±1.25V to ±5.5V dual supply) and is housed in an 8-pin TSSOP/MSOP surface-mount package. The MAX972CUA-T is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX972CUA-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Dual-channel comparator with integrated voltage reference
• Output Configuration: Open-drain topology
• Supply Voltage Compatibility: Single supply 2.5V ~ 11V and dual supply ±1.25V ~ 5.5V
• Electrical Performance: Input offset voltage 10mV @ 5V, quiescent current 4µA maximum, CMRR/PSRR 80dB
• Package Specification: 8-pin TSSOP/MSOP surface-mount package with 3.00mm width
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The substitute part MAX972CUA+T maintains identical electrical specifications and package configuration. The primary distinction is product status and packaging format: MAX972CUA-T is obsolete with tube packaging, while MAX972CUA+T is active with tape and reel (TR) packaging.

Parameter Comparison

Engineering Selection Recommendations

The MAX972CUA+T is the direct functional equivalent of the MAX972CUA-T. Selection between these parts is determined by procurement and supply chain requirements rather than electrical or mechanical differences.

For New Designs and Ongoing Production: The MAX972CUA+T is the appropriate selection. This part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring continued availability, technical support, and compliance documentation. The tape and reel packaging format is standard for automated assembly processes and high-volume manufacturing.

For Legacy System Support: The MAX972CUA-T remains electrically and mechanically compatible with existing designs. However, as an obsolete product, procurement may face supply constraints. The MAX972CUA+T provides identical electrical performance and package compatibility for replacement or redesign scenarios.

Both parts carry ROHS3 compliance and MSL Level 1 rating, confirming environmental and moisture handling equivalence. No design modifications are required when transitioning between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are MAX972CUA-T and MAX972CUA+T electrically identical?

A: Yes. Both parts are manufactured by Analog Devices Inc./Maxim Integrated with identical electrical specifications, including supply voltage range (2.5V ~ 11V single, ±1.25V ~ ±5.5V dual), input offset voltage (10mV @ 5V), quiescent current (4µA), and CMRR/PSRR performance (80dB). They are functionally interchangeable at the circuit level.

Q: What is the difference between these part numbers?

A: The primary differences are product status and packaging format. MAX972CUA-T is obsolete and supplied in tube packaging. MAX972CUA+T is active and supplied in tape and reel (TR) format. The tape and reel format is optimized for automated pick-and-place assembly.

Q: Can I use MAX972CUA+T as a direct replacement for MAX972CUA-T in existing designs?

A: Yes. The MAX972CUA+T is a direct substitute. No circuit modifications, PCB layout changes, or firmware updates are required. The 8-pin TSSOP/MSOP package dimensions and pinout are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings. Environmental and regulatory compliance is equivalent.

Q: Which part should I specify for new production orders?

A: Specify MAX972CUA+T for new designs and ongoing production. This part has active status with the manufacturer, ensuring reliable supply chain access and continued technical support.

Q: Is the 8-pin TSSOP/MSOP package compatible with my existing PCB?

A: Yes, provided your PCB footprint is designed for 8-pin TSSOP or MSOP with 3.00mm width. Both MAX972CUA-T and MAX972CUA+T use this identical package specification. Verify your PCB footprint matches the 0.118" (3.00mm) width dimension.
