Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX951ESA-T is determined by strict equivalence across the following parameters:

• Base Product Number: Both parts share the MAX951 base designation, confirming identical die and functional specifications
• Package / Case: Both utilize 8-SOIC (0.154", 3.90mm Width) surface mount packaging, ensuring mechanical and electrical compatibility with existing PCB layouts
• Functional Classification: Both are classified as Amplifier, Comparator, Reference ICs for smart card applications
• Compliance Standards: Both maintain ROHS3 compliance, REACH unaffected status, and identical MSL rating of 1 (Unlimited)
• Supplier Device Package: Both specify 8-SOIC as the supplier device package

The primary distinction between the main part and its substitute is the packaging format and product status, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MAX951ESA+T is the direct functional equivalent of the MAX951ESA-T. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, package geometry, and compliance certifications.

The MAX951ESA-T is classified as obsolete, while the MAX951ESA+T maintains active product status. For new designs or ongoing procurement, the MAX951ESA+T is the appropriate selection. The primary difference is packaging format: the MAX951ESA-T is supplied in tube packaging, while the MAX951ESA+T is supplied in Tape & Reel (TR) format. This distinction affects handling, storage, and automated assembly processes but does not impact electrical or mechanical compatibility.

Both parts satisfy ROHS3 compliance requirements and maintain identical MSL ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can MAX951ESA+T replace MAX951ESA-T in existing designs?

A: Yes. Both parts share identical electrical specifications, functional classification, and 8-SOIC package geometry. No circuit modifications are required.

Q: What is the difference between MAX951ESA-T and MAX951ESA+T?

A: The parts are electrically and functionally identical. The difference is packaging format: MAX951ESA-T uses tube packaging, while MAX951ESA+T uses Tape & Reel (TR) format. This affects procurement and assembly logistics but not component performance.

Q: Why is MAX951ESA-T listed as obsolete?

A: MAX951ESA-T has reached end-of-life status. The MAX951ESA+T remains in active production and is the recommended source for new procurement.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH unaffected status, MSL rating of 1 (Unlimited), and ECCN/HTSUS classifications.

Q: Is the 8-SOIC package identical for both parts?

A: Yes. Both parts use the same 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring PCB layout compatibility without modification.

Q: Can MAX951ESA+T be used in high-volume automated assembly?

A: Yes. The Tape & Reel (TR) packaging of MAX951ESA+T is optimized for automated pick-and-place assembly processes.
