MAX975ESA-T Equivalent & Substitute Parts

Part Overview

The MAX975ESA-T is a general-purpose CMOS comparator with rail-to-rail output and TTL compatibility, housed in an 8-SOIC surface mount package. This device is classified as obsolete, making identification of suitable substitutes essential for ongoing production support and design continuity. The MAX975ESA-T operates across a 2.7V to 5.25V supply range and is designed for applications requiring low input offset voltage and controlled propagation delay characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX975ESA-T is determined by strict equivalence across the following electrical and mechanical parameters:

• Supply voltage range: 2.7V ~ 5.25V
• Input offset voltage: 2mV @ 5V maximum
• Input bias current: 0.1µA @ 5.25V maximum
• Quiescent current: 500µA maximum
• Common-mode rejection ratio: 90dB typical
• Power supply rejection ratio: 90dB typical
• Propagation delay: 820ns maximum
• Hysteresis: 4mV
• Operating temperature range: -40°C ~ 85°C
• Package type: 8-SOIC surface mount
• Output configuration: CMOS, rail-to-rail, TTL compatible
• Single comparator element count

The MAX975ESA+T meets all specified electrical parameters and maintains identical package geometry and mounting characteristics, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The MAX975ESA+T is the appropriate substitute for the obsolete MAX975ESA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and package geometry. The primary distinction is product status: the MAX975ESA-T is obsolete while the MAX975ESA+T maintains active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production support. The MAX975ESA+T is supplied in Tape & Reel packaging, which is standard for high-volume manufacturing operations.

Frequently Asked Questions (FAQ)

Q: Can the MAX975ESA+T directly replace the MAX975ESA-T in existing designs?

A: Yes. The MAX975ESA+T is electrically and mechanically equivalent to the MAX975ESA-T. All electrical parameters, operating ranges, and package specifications are identical. The 8-SOIC package footprint and pin configuration remain unchanged, allowing direct PCB substitution without design modification.

Q: What is the difference between the MAX975ESA-T and MAX975ESA+T part numbers?

A: The suffix designates packaging format. The MAX975ESA-T uses tube packaging, while the MAX975ESA+T uses Tape & Reel (TR) packaging. Tape & Reel is the standard format for automated assembly and high-volume production. Electrical performance is identical.

Q: Why is the MAX975ESA-T classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this specific packaging variant. The MAX975ESA+T remains in active production, providing a direct path for design continuity and supply chain support.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited) ratings. Regulatory and environmental certifications are equivalent.

Q: What is the typical lead time for the MAX975ESA+T?

A: Lead time information is not provided in the technical specifications. Contact the manufacturer or authorized distributor for current availability and delivery schedules.
