Substitute Part Grouping Explanation

Substitution of the MAX952ESA-T is determined by strict equivalence across the following parameters:

• Base Product Number: All substitutes share the MAX952 base designation, ensuring identical die and functional performance
• Package / Case: All substitutes use 8-SOIC (0.154", 3.90mm Width) surface mount packaging, guaranteeing PCB footprint and land pattern compatibility
• Electrical Specifications: Amplifier, comparator, and reference functionality remains constant across all variants
• Application Domain: Smart card circuit integration requirements are met by all listed substitutes
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating are maintained across all parts
• Export Classification: ECCN EAR99 and HTSUS 8542.33.0001 remain consistent

The primary differentiator among substitutes is packaging format (Tube versus Tape & Reel) and product status (Obsolete versus Active).

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement:

Select MAX952ESA+T (Tape & Reel format) or MAX952ESA+ (Tube format) as direct replacements for the obsolete MAX952ESA-T. Both substitute parts carry Active product status, ensuring long-term availability and manufacturer support.

Packaging Format Selection:

• MAX952ESA+T: Tape & Reel packaging is suitable for high-volume automated assembly operations and pick-and-place machine compatibility
• MAX952ESA+: Tube packaging is suitable for lower-volume applications, manual assembly, or inventory management where individual component access is required

Compliance Verification:

All three parts maintain ROHS3 compliance and MSL Level 1 rating. No additional environmental or regulatory qualification is required when transitioning from MAX952ESA-T to either active substitute.

Frequently Asked Questions (FAQ)

Q: Can MAX952ESA+T and MAX952ESA+ be used interchangeably with MAX952ESA-T?

A: Yes. Both parts are electrically and mechanically identical to MAX952ESA-T. The only differences are product status (Active versus Obsolete) and packaging format (Tape & Reel versus Tube). PCB footprint, pin configuration, and functional performance are identical.

Q: What is the difference between Tape & Reel and Tube packaging?

A: Tape & Reel (TR) packaging delivers components on continuous carrier tape suitable for automated pick-and-place assembly. Tube packaging delivers components in plastic tubes suitable for manual handling and lower-volume assembly. Both formats contain the same die and provide identical electrical performance.

Q: Why is MAX952ESA-T marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. Active equivalents (MAX952ESA+T and MAX952ESA+) are available from current inventory and receive ongoing manufacturer support.

Q: Are there any electrical performance differences between the three part numbers?

A: No. All three parts share the MAX952 base product number and deliver identical amplifier, comparator, and reference functionality for smart card applications.

Q: Which substitute should I select for a new design?

A: For new designs, select based on assembly requirements: MAX952ESA+T for automated high-volume production, or MAX952ESA+ for manual assembly or lower-volume applications. Both are Active parts with equivalent long-term availability.

Q: Do all three parts meet the same compliance standards?

A: Yes. MAX952ESA-T, MAX952ESA+T, and MAX952ESA+ all carry ROHS3 compliance, MSL Level 1 rating, EAR99 export classification, and HTSUS code 8542.33.0001.
