MAX9002ESA Equivalent & Substitute Parts

Part Overview

The MAX9002ESA is a linear amplifier and comparator integrated circuit designed for smart card applications. Manufactured by Analog Devices Inc./Maxim Integrated, this component is packaged in an 8-SOIC surface mount configuration with a 3.90mm width. The MAX9002ESA is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement continuity. Active alternative versions of this part remain available to support legacy system maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX9002ESA is determined by strict equivalence across the following critical parameters:

Functional Equivalence: Both the main part and substitute must operate as amplifier and comparator integrated circuits within the smart card application domain.

Package Compatibility: The 8-SOIC package with 0.154" width and 3.90mm physical dimensions must be identical to ensure PCB layout compatibility and mechanical fit.

Electrical Classification: Both components must belong to the Linear, Amplifiers category with identical base product number (MAX9002).

Compliance Alignment: RoHS3 compliance, REACH unaffected status, and MSL 1 rating must be maintained across all substitute selections.

Mounting Configuration: Surface mount technology must be consistent between the original and substitute components.

The MAX9002ESA+ qualifies as a direct substitute based on complete alignment with all these parameters. The primary distinction is product status: the MAX9002ESA is obsolete while the MAX9002ESA+ maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Component Replacement: The MAX9002ESA+ is the appropriate selection for applications currently using the obsolete MAX9002ESA. Both components share identical electrical specifications, package dimensions, and compliance certifications. The MAX9002ESA+ maintains active production status through Analog Devices Inc./Maxim Integrated, ensuring long-term availability and supply chain reliability.

Compliance Verification: Both components satisfy ROHS3 compliance requirements and maintain REACH unaffected status, making them suitable for regulated markets and applications with environmental compliance mandates. The MSL 1 rating indicates unlimited moisture sensitivity tolerance, eliminating moisture-related handling constraints during assembly and storage.

Supply Chain Continuity: Selection of the MAX9002ESA+ addresses the obsolescence of the original MAX9002ESA while maintaining full functional and mechanical compatibility. This substitution requires no PCB redesign, assembly process modification, or firmware adjustment.

Frequently Asked Questions (FAQ)

Q: Can the MAX9002ESA+ directly replace the MAX9002ESA without PCB modifications?

A: Yes. The MAX9002ESA+ is mechanically and electrically equivalent to the MAX9002ESA. Both components use the identical 8-SOIC package with 0.154" width and 3.90mm dimensions, enabling direct pin-for-pin substitution on existing PCB layouts without design changes.
