MAX9000ESA Equivalent & Substitute Parts

Part Overview

The MAX9000ESA 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, which necessitates identification of equivalent substitute components for ongoing design support and procurement continuity. The MAX9000ESA+ serves as the direct active substitute, offering identical electrical and mechanical specifications with current manufacturing status.

Substitute Part Grouping Explanation

Substitution of the MAX9000ESA is determined by strict equivalence across the following parameters:

Critical Substitution Criteria:

• Identical device type classification (Amplifier, Comparator, Reference)
• Matching package specification (8-SOIC with 0.154" / 3.90mm width)
• Surface mount mounting type
• Identical application domain (Smart Card)
• Equivalent environmental compliance (RoHS3, REACH Unaffected)
• Matching moisture sensitivity level (MSL 1)

The MAX9000ESA+ meets all substitution criteria as a direct equivalent. The primary distinction is product status: MAX9000ESA is obsolete, while MAX9000ESA+ maintains active manufacturing status. Both components share identical electrical specifications, package geometry, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Use MAX9000ESA+ as the primary component selection. This part maintains active manufacturing status and identical compliance certifications (ROHS3, REACH Unaffected), ensuring long-term supply chain reliability and regulatory alignment.

For Legacy System Support: The MAX9000ESA+ provides direct substitution for existing MAX9000ESA implementations. Identical package geometry (8-SOIC, 0.154" width), mounting type (surface mount), and device classification ensure form-fit-function compatibility without PCB redesign.

Compliance Considerations: Both components satisfy ROHS3 compliance and REACH unaffected status. MSL rating of 1 (unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can MAX9000ESA+ directly replace MAX9000ESA in existing designs?

A: Yes. Both components share identical package specifications (8-SOIC, 0.154" / 3.90mm width), mounting type (surface mount), device classification (Amplifier, Comparator, Reference), and compliance certifications. No PCB modification is required.

Q: What is the primary difference between MAX9000ESA and MAX9000ESA+?
