MAX983CUA-T Equivalent & Substitute Parts

Part Overview

The MAX983CUA-T is a dual comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This linear IC operates across a supply voltage range of 2.5V to 11V (single supply) or ±1.25V to 5.5V (dual supply), featuring an 8-pin TSSOP/MSOP package. The device is classified as obsolete, making identification of compatible substitutes essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX983CUA-T is determined by strict equivalence across the following critical parameters:

• Functional Type: Dual comparator with integrated voltage reference
• Package Compatibility: 8-pin TSSOP/MSOP form factor (0.118", 3.00mm width)
• Electrical Performance: Supply voltage range (2.5V ~ 11V single, ±1.25V ~ 5.5V dual), input offset voltage (10mV @ 5V), quiescent current (6µA), CMRR/PSRR (80dB), hysteresis (50mV)
• Operating Temperature Range: 0°C ~ 70°C
• Compliance: ROHS3 compliant, MSL Level 1

The MAX983CUA+T qualifies as a direct substitute based on identical electrical specifications, package geometry, and compliance certifications. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the original tube packaging.

Parameter Comparison

Engineering Selection Recommendations

The MAX983CUA+T is a direct electrical and mechanical equivalent to the MAX983CUA-T. Both devices share identical electrical specifications, package geometry, and compliance certifications (ROHS3, REACH Unaffected). The substitute part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring continued availability and manufacturing support.

The primary consideration for selection is packaging format. The original MAX983CUA-T is supplied in tube packaging, while the MAX983CUA+T is supplied in Tape & Reel format. This distinction affects handling, storage, and automated assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX983CUA+T replace MAX983CUA-T in production?

A: Yes. Both parts are electrically and mechanically identical. The substitute maintains the same supply voltage range (2.5V ~ 11V single, ±1.25V ~ 5.5V dual), input offset voltage (10mV @ 5V), quiescent current (6µA), and package geometry (8-pin TSSOP/MSOP). Compliance certifications are equivalent.

Q: What is the difference between these two part numbers?

A: The difference is packaging format. MAX983CUA-T is supplied in tube packaging, while MAX983CUA+T is supplied in Tape & Reel (TR) format. Electrical specifications and pin configuration are identical.

Q: Is the substitute part still in production?

A: Yes. MAX983CUA+T maintains active product status with Analog Devices Inc./Maxim Integrated, whereas the original MAX983CUA-T is classified as obsolete. This makes the substitute the recommended choice for new designs and ongoing production.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Compliance certifications are identical.

Q: What is the operating temperature range?

A: Both parts operate across 0°C to 70°C. This specification is identical between the original and substitute.

Q: Can I use Tape & Reel packaging in manual assembly?

A: Tape & Reel packaging is optimized for automated pick-and-place assembly. Manual assembly is possible but requires manual extraction from the tape carrier. Tube packaging is more convenient for manual assembly processes.
