MAX952ESA Equivalent & Substitute Parts

Part Overview

The MAX952ESA is a linear amplifier, comparator, and reference IC designed for smart card applications in an 8-SOIC surface mount package. This part is classified as obsolete, indicating it has reached end-of-life status and is no longer in active production. Finding equivalent or substitute parts is necessary to support ongoing system maintenance, design updates, and procurement continuity for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX952ESA is determined by strict alignment with the following parameters:

Critical Substitution Criteria:

• Identical base product number (MAX952)
• Identical package type (8-SOIC with 0.154" / 3.90mm width)
• Identical functional classification (Amplifier, Comparator, Reference IC)
• Identical application domain (Smart Card)
• Identical mounting type (Surface Mount)
• Identical moisture sensitivity level (MSL 1 - Unlimited)
• Identical REACH and ECCN classifications

Substitute parts must maintain full electrical and mechanical compatibility within the specified 8-SOIC package footprint and pinout configuration. Packaging format (tube, tray, or reel) does not affect functional substitution but may impact procurement and handling procedures.

Parameter Comparison

Engineering Selection Recommendations

MAX952ESA+ as Direct Substitute:

The MAX952ESA+ is a direct functional equivalent to the MAX952ESA. Both parts share identical electrical specifications, pinout configuration, and package dimensions. The primary distinction is product lifecycle status: MAX952ESA is obsolete while MAX952ESA+ maintains active production status.

Compliance Considerations:

The MAX952ESA+ offers improved regulatory compliance through ROHS3 certification, whereas the original MAX952ESA is RoHS non-compliant. For new designs or systems requiring regulatory compliance with current environmental standards, MAX952ESA+ is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, either part functions identically within the application.

Availability and Procurement:

MAX952ESA+ is currently in active production with documented inventory availability, making it the preferred choice for ongoing procurement. The original MAX952ESA, being obsolete, has limited remaining stock and no future manufacturing planned.

Frequently Asked Questions (FAQ)

Q: Can MAX952ESA+ be used as a direct replacement for MAX952ESA in existing designs?

A: Yes. Both parts are electrically and mechanically identical. They share the same pinout, package footprint (8-SOIC), and functional specifications for amplifier, comparator, and reference applications in smart card systems. No circuit modifications are required.

Q: What is the difference between MAX952ESA and MAX952ESA+?

A: The parts are functionally equivalent. The primary differences are: (1) MAX952ESA is obsolete; MAX952ESA+ is in active production; (2) MAX952ESA is RoHS non-compliant; MAX952ESA+ is ROHS3 compliant; (3) MAX952ESA+ has higher documented inventory availability.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use identical 8-SOIC packaging with 0.154" (3.90mm) width. Pinout configuration and pad layout are identical, ensuring direct PCB compatibility.

Q: Does the packaging format (tube vs. other formats) affect substitution?

A: No. Packaging format affects procurement, storage, and handling procedures but does not impact electrical or mechanical compatibility. The functional part remains identical regardless of packaging format.

Q: Which part should be selected for new designs?

A: MAX952ESA+ should be selected for new designs. It is in active production, ROHS3 compliant, and represents the current manufacturing standard for this product line.

Q: Can MAX952ESA be used if MAX952ESA+ is unavailable?

A: If MAX952ESA+ is unavailable and MAX952ESA stock exists, it can be used as a functional equivalent provided the application does not require RoHS compliance. Verify availability through authorized distributors before committing to this option.
