Substitute Part Grouping Explanation

Substitution eligibility for the VT1189SAFQR is determined by the following criteria:

• Manufacturer Consistency: Parts must originate from Analog Devices Inc./Maxim Integrated to ensure design compatibility and performance characteristics
• Base Product Series: Substitute parts must share the VT1189 base product number, ensuring functional equivalence within the switching regulator IC output category
• Category Classification: All substitutes must be classified as Power Management (PMIC) components with SMD packaging
• Regulatory Compliance: Parts must maintain ROHS3 compliance and REACH Unaffected status to satisfy environmental and regulatory requirements
• Functional Description: Substitute parts must perform the identical switching regulation function as specified in the original design

Parameter Comparison

Engineering Selection Recommendations

The VT1189SAFQX is the manufacturer-recommended substitute for the obsolete VT1189SAFQR. Both parts maintain identical functional classification as Switching Regulator IC Output components within the VT1189 base product series and are manufactured by Analog Devices Inc./Maxim Integrated.

Key selection factors:

• Product Status: The VT1189SAFQX carries Active product status, ensuring continued availability and manufacturer support, whereas the VT1189SAFQR is Obsolete
• Regulatory Compliance: Both parts satisfy ROHS3 compliance and REACH Unaffected requirements, maintaining equivalent environmental and regulatory standing
• Moisture Sensitivity: The VT1189SAFQX specifies MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for the original part. This difference requires evaluation based on storage and handling conditions in your supply chain
• Manufacturer Recommendation: The VT1189SAFQX is designated as the manufacturer-recommended alternative, indicating functional and electrical equivalence for the switching regulation application

Frequently Asked Questions (FAQ)

Q: Can the VT1189SAFQX directly replace the VT1189SAFQR in existing designs?

A: Yes. Both parts share the VT1189 base product number, identical functional description as Switching Regulator IC Output components, and are manufactured by Analog Devices Inc./Maxim Integrated. The VT1189SAFQX is the manufacturer-recommended substitute.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The VT1189SAFQR specifies MSL 1 (Unlimited), allowing indefinite storage without baking requirements. The VT1189SAFQX specifies MSL 3 (168 Hours), requiring moisture baking procedures if the part has been exposed to humidity for extended periods. Verify your storage and handling protocols support MSL 3 requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the VT1189SAFQR and VT1189SAFQX are ROHS3 Compliant and REACH Unaffected, satisfying equivalent environmental and regulatory requirements.

Q: Why is the original part marked as Obsolete?

A: The VT1189SAFQR has reached end-of-life status. The VT1189SAFQX, carrying Active product status, represents the current production alternative within the VT1189 switching regulator series.

Q: Are there packaging differences between these parts?

A: Both parts are specified as SMD (Surface Mount Device) components. No packaging format differences are indicated in the provided specifications.
