Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX4375TESD is determined by strict equivalence across the following critical parameters:

Functional Equivalence: Both the main part and substitute must share identical base product number (MAX4375), functional classification (Amplifier, Comparator, Reference), and application domain (Current Sensing, Power Management).

Package Compatibility: Both parts must utilize the same physical package specification: 14-SOIC (0.154", 3.90mm Width) with surface mount mounting type. This ensures mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Environmental & Compliance Alignment: Both parts must maintain identical Moisture Sensitivity Level (MSL 1 - Unlimited) and REACH Status (REACH Unaffected) to ensure equivalent reliability and regulatory compliance in target applications.

Supplier Device Package: Both parts must conform to the same supplier device package designation (14-SOIC) to guarantee pin configuration and footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

MAX4375TESD+ as Primary Substitute: The MAX4375TESD+ is the direct equivalent substitute for the obsolete MAX4375TESD. Both parts maintain identical functional specifications, package geometry, and electrical interface characteristics required for 1:1 component replacement.

Product Status Consideration: The MAX4375TESD carries obsolete product status, indicating discontinued manufacturing and limited long-term availability. The MAX4375TESD+ maintains active product status with confirmed inventory of 1248 pieces in stock, ensuring supply chain continuity and design longevity.

Compliance Advantage: The MAX4375TESD+ achieves ROHS3 compliance, whereas the original MAX4375TESD is RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the MAX4375TESD+ provides enhanced regulatory alignment without functional or mechanical compromise.

Packaging Format: The MAX4375TESD+ is supplied in tube packaging, compared to the original part's unspecified packaging format. Tube packaging provides standardized handling, storage, and automated assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can MAX4375TESD+ replace MAX4375TESD in existing designs without PCB modification?

A: Yes. Both parts utilize identical 14-SOIC package geometry (0.154", 3.90mm width) and surface mount configuration. Pin-to-pin compatibility is guaranteed, requiring no PCB layout changes or assembly process modifications.

Q: What is the significance of the product status difference between obsolete and active?

A: Obsolete status indicates the MAX4375TESD is no longer manufactured by Analog Devices Inc./Maxim Integrated. Active status for MAX4375TESD+ confirms ongoing production and long-term availability. For new designs or production continuity, the active MAX4375TESD+ is the appropriate selection.

Q: Does RoHS3 compliance of MAX4375TESD+ affect electrical performance compared to the non-compliant MAX4375TESD?

A: RoHS3 compliance reflects manufacturing process and material composition standards, not electrical performance. Both parts maintain identical functional specifications for current sensing and power management applications. RoHS3 compliance of MAX4375TESD+ provides regulatory advantage without performance trade-offs.

Q: Are there any moisture sensitivity or environmental handling differences between these parts?

A: No. Both MAX4375TESD and MAX4375TESD+ maintain identical Moisture Sensitivity Level (MSL 1 - Unlimited) and REACH Status (REACH Unaffected). Storage, handling, and environmental requirements are equivalent.

Q: What inventory considerations should guide part selection?

A: MAX4375TESD inventory is limited at 794 pieces. MAX4375TESD+ inventory is substantially higher at 1248 pieces. For production planning and supply chain risk mitigation, MAX4375TESD+ provides superior availability assurance.

Q: Are the ECCN and HTSUS classifications identical for both parts?

A: Yes. Both MAX4375TESD and MAX4375TESD+ share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, ensuring equivalent export control and tariff treatment.
