Substitute Part Grouping Explanation

Substitution of the VT254FQR-ADJ is based on alignment within the VT254 base product family from Analog Devices Inc./Maxim Integrated. The primary substitution criterion is maintenance of the same base product designation (VT254), which ensures functional and electrical compatibility at the component level. The substitute part must retain identical classification as a linear voltage regulator IC within the Power Management (PMIC) category. Compliance certifications, including ROHS3 and REACH status, must be maintained to ensure regulatory and environmental compatibility. The substitute part must be in active product status to ensure long-term availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The VT254FQX-ADJ is the manufacturer-recommended substitute for the obsolete VT254FQR-ADJ. Both parts share identical base product designation (VT254), functional classification as linear voltage regulators, and regulatory compliance profiles. The VT254FQX-ADJ maintains active product status, ensuring continued manufacturer support, availability, and compliance documentation. Selection of the VT254FQX-ADJ eliminates obsolescence risk while preserving compliance certifications (ROHS3, REACH Unaffected) and moisture sensitivity specifications required for component qualification.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the VT254FQR-ADJ? A: The VT254FQR-ADJ is classified as obsolete. The VT254FQX-ADJ is the active equivalent within the same VT254 base product family, ensuring continued availability and manufacturer support.

Q: Are the VT254FQR-ADJ and VT254FQX-ADJ functionally equivalent? A: Both parts are linear voltage regulator ICs within the Power Management (PMIC) category, sharing the same base product number (VT254) and functional classification. They maintain identical RoHS and REACH compliance status.

Q: Do compliance certifications remain unchanged with this substitution? A: Yes. Both the VT254FQR-ADJ and VT254FQX-ADJ are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Is the VT254FQX-ADJ available in the same packaging as the VT254FQR-ADJ? A: Packaging information is not specified in the available technical parameters for either part. Verify packaging compatibility through the manufacturer's current datasheet or contact Analog Devices Inc./Maxim Integrated directly.

Q: Can the VT254FQX-ADJ be used as a direct replacement in existing designs? A: The VT254FQX-ADJ shares the same base product family and functional classification. Confirm electrical and mechanical compatibility through detailed datasheet review before implementation in production designs.
