Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4374FEUB is determined by the following critical parameters:

Functional Equivalence: Both the main part and substitute must share the same base product number (MAX4374) and identical functional classification as Amplifier, Comparator, Reference IC.

Package Compatibility: The substitute must utilize the identical package specification: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width) with 10-uMAX/uSOP supplier device package designation.

Application Alignment: The substitute must support the same applications: Current Sensing and Power Management.

Mounting Technology: Surface mount mounting type must be maintained.

Environmental Specifications: Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) must be preserved.

Regulatory Compliance: REACH and ECCN classifications must remain consistent.

The MAX4374FEUB+ qualifies as a direct substitute based on full alignment across all these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MAX4374FEUB+

The MAX4374FEUB+ is the direct substitute for the obsolete MAX4374FEUB. Both parts share identical functional specifications, package geometry, and application requirements. The MAX4374FEUB+ carries an active product status, ensuring ongoing availability and supply chain support.

Compliance Advantage: The MAX4374FEUB+ achieves ROHS3 compliance, whereas the original MAX4374FEUB is RoHS non-compliant. For new designs or systems subject to RoHS regulatory requirements, the MAX4374FEUB+ is the appropriate selection.

Packaging Consideration: The MAX4374FEUB+ is supplied in tube packaging, which may differ from the original part's packaging format. Verify packaging compatibility with assembly and handling procedures.

Regulatory Status: Both parts maintain identical REACH and ECCN classifications, ensuring consistent export and regulatory compliance across substitution.

Frequently Asked Questions (FAQ)
