MAX923CUA-T Equivalent & Substitute Parts

Part Overview

The MAX923CUA-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 to 11V single supply, ±1.25V to ±5.5V dual supply) and is housed in an 8-TSSOP/8-MSOP surface mount package. The device is currently classified as obsolete, making identification of equivalent parts essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX923CUA-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 to 11V (single supply) and ±1.25V to ±5.5V (dual supply)
• Electrical Performance: Input offset voltage (10mV @ 5V), output current (50mA typical), quiescent current (7.5µA maximum), propagation delay (12µs maximum), hysteresis (50mV)
• Package Compatibility: 8-TSSOP/8-MSOP surface mount package with 0.118" (3.00mm) width
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The MAX923CUA+T represents a direct equivalent part, differing only in packaging format (Tape & Reel versus individual unit packaging) while maintaining identical electrical specifications and functional performance.

Parameter Comparison

Engineering Selection Recommendations

The MAX923CUA+T is the direct equivalent for the obsolete MAX923CUA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and maintain identical electrical specifications, functional performance, and package dimensions. The primary distinction is product status: the MAX923CUA-T is obsolete while the MAX923CUA+T is active, ensuring continued availability and supply chain reliability.

Both parts carry ROHS3 compliance certification and MSL Level 1 rating, confirming environmental and moisture handling standards. The MAX923CUA+T is supplied in Tape & Reel format, which is standard for production-volume procurement and automated assembly processes.

For new designs or production continuity, the MAX923CUA+T is the appropriate selection. For legacy system repairs requiring exact packaging format matching, component-level evaluation of the original unit packaging may be necessary, though electrical equivalence is complete.

Frequently Asked Questions (FAQ)

Q: Can the MAX923CUA+T directly replace the MAX923CUA-T in existing designs?

A: Yes. Both parts are electrically and functionally identical. The MAX923CUA+T operates across the same supply voltage range (2.5V to 11V single supply, ±1.25V to ±5.5V dual supply), delivers identical output current (50mA typical), and maintains the same propagation delay (12µs maximum) and hysteresis characteristics (50mV). Pin configuration and package dimensions are identical.

Q: What is the difference between MAX923CUA-T and MAX923CUA+T?

A: The parts differ only in packaging format and product status. The MAX923CUA-T is supplied as individual units and is classified as obsolete. The MAX923CUA+T is supplied in Tape & Reel format and maintains active product status with ongoing manufacturer support.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the MAX923CUA-T and MAX923CUA+T carry ROHS3 compliance certification and MSL Level 1 rating, confirming compliance with environmental and moisture sensitivity standards.

Q: What is the operating temperature range for these comparators?

A: Both parts operate across 0°C to 70°C. This range applies to all electrical specifications, including input offset voltage, propagation delay, and quiescent current.

Q: Can these parts be used in dual supply applications?

A: Yes. Both the MAX923CUA-T and MAX923CUA+T support dual supply operation with voltage ranges of ±1.25V to ±5.5V, in addition to single supply operation (2.5V to 11V).

Q: What is the package type for these comparators?

A: Both parts use the 8-TSSOP/8-MSOP surface mount package with a width of 0.118" (3.00mm). This package is suitable for automated assembly and high-density PCB layouts.
