Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX4373TESA is determined by the following critical parameters:

Functional Equivalence: Identical device type (Amplifier, Comparator, Reference) with matching application scope (Current Sensing, Power Management).

Package Compatibility: Identical package designation (8-SOIC with 0.154" / 3.90mm width) ensuring mechanical and electrical pin compatibility on printed circuit boards.

Manufacturer Continuity: Same manufacturer (Analog Devices Inc./Maxim Integrated) and base product number (MAX4373) to ensure design specification alignment.

Environmental Compliance: Matching Moisture Sensitivity Level (MSL 1 - Unlimited) and REACH status (REACH Unaffected) to maintain reliability and regulatory compliance.

The substitute part MAX4373TESA+ meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MAX4373TESA+ is the direct equivalent for MAX4373TESA applications.

Justification: The MAX4373TESA+ maintains identical functional specifications, package configuration, and pin compatibility. Both devices share the same base product number (MAX4373) and are manufactured by the same supplier (Analog Devices Inc./Maxim Integrated).

Product Status Consideration: The MAX4373TESA is classified as obsolete, while MAX4373TESA+ is active production status. Selection of MAX4373TESA+ ensures access to current manufacturing inventory and ongoing supplier support.

Compliance Upgrade: MAX4373TESA+ achieves ROHS3 compliance, whereas the original MAX4373TESA is RoHS non-compliant. This represents an improvement in environmental and regulatory alignment for new designs or production transitions.

Packaging Availability: MAX4373TESA+ is supplied in Tube packaging, compared to the original part. Both maintain identical electrical and mechanical specifications for circuit board integration.

Frequently Asked Questions (FAQ)

Q: Can MAX4373TESA+ be used as a direct replacement for MAX4373TESA in existing designs?

A: Yes. MAX4373TESA+ is a direct equivalent. Both devices share identical package configuration (8-SOIC), pin assignments, functional type (Amplifier, Comparator, Reference), and application scope (Current Sensing, Power Management). No circuit redesign is required.

Q: What is the difference between MAX4373TESA and MAX4373TESA+?

A: The primary differences are product status and RoHS compliance. MAX4373TESA is obsolete and RoHS non-compliant. MAX4373TESA+ is active production status and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any package compatibility concerns when substituting MAX4373TESA+ for MAX4373TESA?

A: No. Both parts use the 8-SOIC package with identical dimensions (0.154" / 3.90mm width). Pin count, spacing, and mounting type (Surface Mount) are identical. PCB layouts and assembly processes require no modification.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical performance. Both MAX4373TESA and MAX4373TESA+ deliver identical functional specifications for current sensing and power management applications.

Q: What is the inventory status for these parts?

A: MAX4373TESA has 2300 pieces in stock (obsolete status). MAX4373TESA+ has 1531 pieces in stock (active production). For new procurement, MAX4373TESA+ is the recommended selection due to active production status and ongoing availability.

Q: Are there any regulatory or certification differences between these parts?

A: Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8542.33.0001). The primary regulatory difference is RoHS compliance: MAX4373TESA is non-compliant, while MAX4373TESA+ is ROHS3 compliant.
