MAX932CUA-T Equivalent & Substitute Parts

Part Overview

The MAX932CUA-T is a dual comparator with integrated voltage reference, manufactured by Analog Devices Inc./Maxim Integrated. This CMOS/TTL output comparator operates across a wide supply voltage range (2.5V ~ 11V single supply, ±1.25V ~ 5.5V dual supply) and integrates a precision voltage reference, making it suitable for precision measurement and signal conditioning applications.

The MAX932CUA-T is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and field service applications.

Substitute Part Grouping Explanation

Substitution of the MAX932CUA-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Dual comparator with integrated voltage reference
• Output Configuration: CMOS/TTL compatible outputs
• Supply Voltage Range: 2.5V ~ 11V (single supply), ±1.25V ~ 5.5V (dual supply)
• Electrical Performance: Input offset voltage (10mV @ 5V), quiescent current (6µA max), propagation delay (12µs max), hysteresis (50mV)
• Package Compatibility: 8-TSSOP/8-MSOP surface mount package with 0.118" (3.00mm) width
• Regulatory Compliance: ROHS3 compliant, MSL Level 1

The MAX932CUA+T is a direct substitute, differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). All electrical specifications, pin configuration, and functional characteristics remain identical.

Engineering Selection Recommendations

The MAX932CUA+T is a direct functional and electrical equivalent to the MAX932CUA-T. Selection between these parts should be based on the following criteria:

Product Status: The MAX932CUA+T carries Active status from the manufacturer, ensuring continued support, availability, and compliance with current manufacturing standards. The MAX932CUA-T is Obsolete, which may result in limited inventory and no manufacturer support for future production runs.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL Level 1 rating, meeting current environmental and moisture sensitivity requirements for industrial and commercial applications.

Packaging Considerations: The MAX932CUA+T is supplied in Tape & Reel format, which is standard for automated assembly processes. The MAX932CUA-T bulk packaging may be suitable for manual assembly or low-volume applications. Tape & Reel format provides better component protection and traceability during manufacturing.

Electrical Equivalence: All electrical parameters, including supply voltage range, input offset voltage, quiescent current, propagation delay, and hysteresis, are identical between the two parts. Pin configuration and functional behavior are unchanged.

For new designs or production continuity, the MAX932CUA+T is the preferred selection due to its Active status and standard Tape & Reel packaging format.

Frequently Asked Questions (FAQ)

Q: Are the MAX932CUA-T and MAX932CUA+T pin-compatible?

A: Yes. Both parts use the identical 8-pin TSSOP/MSOP package with 0.118" (3.00mm) width. Pin configuration, signal names, and functional behavior are identical. Direct PCB layout compatibility is maintained.

Q: Can the MAX932CUA+T replace the MAX932CUA-T in existing designs?

A: Yes. The MAX932CUA+T is a direct substitute with identical electrical specifications, supply voltage range, output type, and operating temperature range. No circuit modifications are required.

Q: What is the difference between the MAX932CUA-T and MAX932CUA+T?

A: The primary differences are product status and packaging format. The MAX932CUA-T is Obsolete and supplied in bulk packaging. The MAX932CUA+T is Active and supplied in Tape & Reel format. All electrical and functional specifications are identical.

Q: Why is the MAX932CUA-T classified as Obsolete?
