Key Parameters

Substitute Part Grouping Explanation

Substitution of the RV4141AN is determined by the following critical parameters:

• Base Product Number: Both parts share the RV4141 base designation, confirming functional equivalence at the silicon level
• Functional Category: Both are Ground Fault Protection PMICs with identical supply current (10mA) and operating temperature range (-35°C ~ 80°C)
• Manufacturer: Both are manufactured by onsemi, ensuring consistent design and performance characteristics
• Compliance & Certifications: Both maintain ROHS3 compliance and REACH unaffected status

The primary difference between the main part and substitute is the package format: the RV4141AN uses through-hole 8-DIP packaging, while the RV4141AMT uses surface-mount 8-SOIC packaging. This distinction affects PCB layout and assembly methodology but does not alter the electrical functionality or performance specifications.

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole PCB Designs: The RV4141AN remains the appropriate choice when the existing PCB layout utilizes through-hole mounting. Both the main part and substitute share identical electrical specifications and compliance certifications.

For Surface-Mount PCB Designs: The RV4141AMT provides functional equivalence with surface-mount assembly compatibility. This substitution requires PCB redesign to accommodate 8-SOIC footprint instead of 8-DIP.

Compliance Considerations: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications in restricted substance environments.

Moisture Handling: The RV4141AN carries MSL 1 (unlimited moisture sensitivity), while the RV4141AMT carries MSL 4 (72-hour limit). For applications with extended storage or high-humidity environments, the RV4141AN presents lower moisture management requirements.

Frequently Asked Questions (FAQ)

Q: Can RV4141AMT directly replace RV4141AN without PCB modification?

A: No. The RV4141AMT uses 8-SOIC surface-mount packaging while the RV4141AN uses 8-DIP through-hole packaging. PCB footprint redesign is required. Direct socket substitution is not possible.

Q: Are the electrical specifications identical between RV4141AN and RV4141AMT?

A: Yes. Both parts share the RV4141 base product number and provide identical ground fault protection functionality with 10mA supply current and -35°C ~ 80°C operating temperature range.

Q: What is the significance of the different MSL ratings?

A: RV4141AN carries MSL 1 (unlimited moisture sensitivity), while RV4141AMT carries MSL 4 (72-hour limit). For applications requiring extended shelf life or storage in humid conditions, the RV4141AN requires less stringent moisture control during handling and storage.

Q: Are both parts still available for new designs?

A: Both parts are classified as obsolete. Availability through authorized distributors should be verified before committing to production designs.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both RV4141AN and RV4141AMT are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for restricted substance compliance.
