MAX983CSA-T Equivalent & Substitute Parts

Part Overview

The MAX983CSA-T is a dual comparator with integrated voltage reference manufactured by Analog Devices Inc./Maxim Integrated. This 8-SOIC surface mount device operates across a supply voltage range of 2.5V to 11V (single supply) or ±1.25V to ±5.5V (dual supply), making it suitable for precision analog signal comparison applications requiring on-chip reference functionality.

The MAX983CSA-T is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance of existing systems, and design continuity where this component was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX983CSA-T is determined by strict equivalence across the following critical parameters:

• Functional equivalence: Dual comparator with integrated voltage reference
• Electrical specifications: 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 (0°C ~ 70°C)
• Package compatibility: 8-SOIC surface mount package with 0.154" width (3.90mm)
• Compliance standards: ROHS3 compliance, MSL Level 1

The substitute part MAX983CSA+T maintains identical electrical and mechanical specifications while differing only in packaging format (Tape & Reel versus individual packaging) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The MAX983CSA+T is a direct functional and electrical equivalent to the MAX983CSA-T. Both parts share identical electrical performance specifications, package geometry, and compliance certifications (ROHS3, MSL Level 1).

The primary distinction is product status: MAX983CSA-T is obsolete while MAX983CSA+T is active. For new designs or ongoing production support, MAX983CSA+T is the appropriate selection. The Tape & Reel packaging format of MAX983CSA+T is standard for high-volume manufacturing and automated assembly processes.

Both parts maintain full compatibility with existing circuit designs and PCB layouts specified for the MAX983 series dual comparator with voltage reference.

Frequently Asked Questions (FAQ)

Q: Can MAX983CSA+T be used as a direct replacement for MAX983CSA-T in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The 8-SOIC package dimensions, pin configuration, and electrical characteristics are equivalent. The only difference is packaging format and product lifecycle status.

Q: What is the difference between MAX983CSA-T and MAX983CSA+T?

A: The parts differ in packaging format and product status. MAX983CSA-T uses individual packaging and is obsolete. MAX983CSA+T uses Tape & Reel packaging and is active. All electrical and mechanical specifications are identical.

Q: Is the 8-SOIC package compatible with existing PCB layouts?

A: Yes. Both parts use the same 8-SOIC package with 0.154" width (3.90mm). PCB footprints, solder pad layouts, and assembly processes remain unchanged.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance status and MSL Level 1 rating. No additional testing or qualification is required when substituting between these parts.

Q: What supply voltage ranges are supported?

A: Both parts support 2.5V to 11V single supply operation or ±1.25V to ±5.5V dual supply operation. Operating temperature range is 0°C to 70°C for both variants.
