MAX975EUA-T Equivalent & Substitute Parts

Part Overview

The MAX975EUA-T is a general-purpose CMOS comparator with rail-to-rail output and TTL compatibility, housed in an 8-TSSOP/8-MSOP surface mount package. This device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. The substitute part maintains identical electrical specifications and mechanical compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX975EUA-T is based on strict equivalence across all allowed electrical and mechanical parameters. The substitute part MAX975EUA+T maintains identical specifications in the following critical areas:

• Supply voltage range (2.7V ~ 5.25V)
• Input offset voltage (2mV @ 5V)
• Input bias current (0.1µA @ 5.25V)
• Quiescent current (500µA)
• CMRR and PSRR performance (82dB CMRR, 90dB PSRR)
• Propagation delay (820ns)
• Hysteresis (4mV)
• Operating temperature range (-40°C ~ 85°C)
• Package configuration (8-TSSOP, 8-MSOP)
• Mounting type (Surface Mount)
• Compliance certifications (ROHS3, REACH Unaffected)

The primary distinction is packaging format: the main part uses tube packaging, while the substitute uses Tape & Reel (TR) format. Both are functionally and mechanically interchangeable for circuit implementation.

Parameter Comparison

Engineering Selection Recommendations

The MAX975EUA+T is a direct functional equivalent to the MAX975EUA-T. Selection between these parts should be based on the following factors:

Product Status: The MAX975EUA-T is obsolete, while MAX975EUA+T maintains active status with Analog Devices. For new designs or long-term production support, MAX975EUA+T is the appropriate choice.

Compliance & Certifications: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Packaging Considerations: The substitute part is supplied in Tape & Reel format, which is standard for automated assembly processes. If tube packaging is specifically required for manual assembly or other operational constraints, this distinction must be evaluated against procurement and logistics requirements.

Availability: MAX975EUA+T demonstrates significantly higher inventory levels (3800 Pcs vs. 814 Pcs), supporting consistent supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are MAX975EUA-T and MAX975EUA+T electrically identical?

A: Yes. Both parts share identical electrical specifications across all measured parameters: supply voltage range, input offset voltage, input bias current, quiescent current, CMRR, PSRR, propagation delay, hysteresis, and operating temperature range.

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

A: The primary difference is packaging format. MAX975EUA-T uses tube packaging, while MAX975EUA+T uses Tape & Reel (TR) format. Both are housed in the same 8-TSSOP/8-MSOP package and are mechanically compatible for PCB assembly.

Q: Can MAX975EUA+T be used as a direct replacement in existing designs?

A: Yes. The substitute part is mechanically and electrically equivalent. No circuit modifications are required. The Tape & Reel format is compatible with standard automated pick-and-place assembly equipment.

Q: Why is MAX975EUA-T listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production lifecycle decisions. The active equivalent MAX975EUA+T provides continued access to this comparator topology.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. MSL ratings are identical at Level 1 (Unlimited).

Q: Which part should be specified for new production?

A: MAX975EUA+T should be specified for new designs and ongoing production due to active product status, higher availability, and standard Tape & Reel packaging format compatible with modern manufacturing processes.
