MAX951EUA-T Equivalent & Substitute Parts

Part Overview

The MAX951EUA-T is an Amplifier, Comparator, and Reference IC designed for smart card applications, manufactured by Analog Devices Inc./Maxim Integrated. This component integrates multiple analog functions in a compact 8-uMAX/uSOP surface mount package. The part is currently classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement planning. Substitute parts must maintain identical electrical specifications, package dimensions, and functional characteristics to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX951EUA-T is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Base product number (MAX951)
• Package type (8-TSSOP, 8-MSOP with 0.118" / 3.00mm width)
• Supplier device package (8-uMAX/uSOP)
• Mounting technology (Surface Mount)
• Functional classification (Amplifier, Comparator, Reference)
• Application domain (Smart Card)
• Moisture sensitivity rating (MSL 1)

The substitute part MAX951EUA+T matches all critical parameters. The primary distinction between the main part and its substitute is the packaging format (loose vs. Tape & Reel) and product status (obsolete vs. active).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement:

The MAX951EUA+T is the appropriate selection for applications requiring the MAX951 amplifier, comparator, and reference IC functionality. This part is currently in active production status, ensuring long-term availability and supply chain stability. The Tape & Reel packaging format is standard for automated assembly operations and high-volume manufacturing environments.

Regulatory and Compliance Considerations:

The MAX951EUA+T achieves ROHS3 compliance, meeting current environmental and hazardous substance restrictions applicable to electronic components in most jurisdictions. Both the main part and substitute maintain identical REACH and ECCN classifications, confirming equivalent regulatory treatment for export and import purposes.

Packaging and Logistics:

The transition from loose packaging to Tape & Reel format does not affect electrical or mechanical compatibility. Tape & Reel packaging provides improved handling efficiency, reduced component damage during storage and transport, and streamlined integration with pick-and-place assembly equipment.

Obsolescence Management:

The MAX951EUA-T is classified as obsolete. Continued reliance on this part number creates supply chain risk. Transition to the MAX951EUA+T eliminates obsolescence exposure while maintaining full functional and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Are MAX951EUA-T and MAX951EUA+T electrically identical?

A: Yes. Both parts share the same base product number (MAX951), functional classification (Amplifier, Comparator, Reference), and are manufactured by Analog Devices Inc./Maxim Integrated. Electrical specifications and performance characteristics are equivalent.

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

A: The suffix indicates packaging format. The "-T" designation represents loose or tube packaging, while the "+T" designation indicates Tape & Reel (TR) packaging. The electrical and mechanical specifications of the die and package remain identical.

Q: Can MAX951EUA+T be used as a direct replacement in existing designs?

A: Yes. The MAX951EUA+T maintains identical package dimensions (8-TSSOP, 8-MSOP, 0.118" / 3.00mm width), pinout, and mounting type (Surface Mount). No PCB redesign or assembly process modification is required.

Q: Why is the main part listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on production discontinuation and market demand. The MAX951EUA-T has been discontinued. The MAX951EUA+T remains in active production and is the current equivalent offering.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance status does not alter electrical performance or physical compatibility. The MAX951EUA+T's ROHS3 compliance provides enhanced environmental and regulatory alignment with current manufacturing standards and customer requirements.

Q: Are there any moisture sensitivity or storage requirement differences?

A: No. Both parts maintain identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Is the Tape & Reel format suitable for manual assembly?

A: Tape & Reel packaging is optimized for automated pick-and-place assembly. For manual assembly operations, components can be removed from the tape and reel as needed. This does not affect component functionality or reliability.
