Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4375FESD-T is determined by strict alignment of the following parameters:

Critical Substitution Criteria:

• Identical package type: 14-SOIC (0.154", 3.90mm Width)
• Matching functional classification: Amplifier, Comparator, Reference IC
• Equivalent application scope: Current Sensing, Power Management
• Identical mounting technology: Surface Mount
• Matching or superior RoHS compliance: ROHS3 Compliant minimum
• Equivalent or superior moisture sensitivity rating: MSL Level 1

The MAX4374FESD+T qualifies as a manufacturer-recommended substitute based on full alignment with these parameters. Both devices share the same package geometry, functional purpose, application domain, and compliance certifications. The primary distinction is product status: MAX4374FESD+T maintains active production status, whereas MAX4375FESD-T is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The MAX4374FESD+T is the manufacturer-recommended substitute for the obsolete MAX4375FESD-T. Selection of this substitute is justified on the following engineering grounds:

Compliance and Regulatory Alignment: Both parts maintain identical ROHS3 compliance status and EAR99 export classification, ensuring regulatory continuity in procurement and deployment.

Package and Mounting Compatibility: Identical 14-SOIC package geometry and surface mount technology enable direct PCB layout compatibility without redesign requirements.

Functional and Application Equivalence: Both devices serve identical functional roles in current sensing and power management applications, with matching amplifier, comparator, and reference IC classifications.

Product Status Advantage: The substitute part maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Moisture and Environmental Ratings: Matching MSL Level 1 rating confirms equivalent handling and storage requirements throughout the component lifecycle.

Frequently Asked Questions (FAQ)

Q: Can MAX4374FESD+T be used as a direct replacement for MAX4375FESD-T in existing designs?

A: Yes. Both parts share identical package geometry (14-SOIC), mounting technology (surface mount), functional classification (Amplifier, Comparator, Reference), and application scope (current sensing, power management). PCB layout and schematic integration remain unchanged.

Q: What is the primary reason for substitution?

A: The MAX4375FESD-T is classified as obsolete. The MAX4374FESD+T maintains active production status, ensuring continued availability and supply chain support.

Q: Are there compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, carry EAR99 export classification, and share identical HTSUS codes (8542.33.0001). Regulatory and compliance requirements remain equivalent.

Q: Does packaging format affect substitution?

A: The MAX4375FESD-T packaging format is not specified in available data. The MAX4374FESD+T is supplied in Tape & Reel (TR) format. Both use identical 14-SOIC package geometry. Verify packaging requirements for your procurement process.

Q: Are moisture sensitivity requirements the same?

A: Yes. Both parts carry MSL Level 1 (Unlimited) rating, indicating identical moisture sensitivity classification and handling requirements.

Q: What inventory status should be considered?

A: The MAX4375FESD-T shows 1068 pieces in stock (new original). The MAX4374FESD+T shows 789 pieces in stock (new original). Inventory levels may vary by supplier and time period.
