VT351AFCR-ADJ Linear Voltage Regulator IC Equivalent & Substitute Parts

Part Overview

The VT351AFCR-ADJ is a linear voltage regulator IC manufactured by Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) component. This adjustable output linear regulator has been designated as obsolete, making identification of suitable substitute parts essential for ongoing design support and component procurement.

The primary reason for sourcing alternative models is the discontinued status of the VT351AFCR-ADJ. Active equivalent parts maintain functional compatibility while ensuring long-term availability and supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the VT351AFCR-ADJ is determined by the following criteria:

• Shared base product number (VT351 series)
• Identical product category (Power Management PMIC)
• Matching functional type (Linear Voltage Regulator IC with adjustable output)
• Equivalent or superior RoHS compliance status (ROHS3 Compliant)
• Same manufacturer (Analog Devices Inc./Maxim Integrated)

The VT351AFCX-ADJ meets all substitution criteria, maintaining the same electrical function and regulatory compliance while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The VT351AFCX-ADJ is the direct substitute for the obsolete VT351AFCR-ADJ. Both components share identical functional specifications within the VT351 linear regulator series and maintain equivalent RoHS3 compliance. The VT351AFCX-ADJ offers the additional advantage of active product status, ensuring continued manufacturer support and supply chain availability. The REACH Unaffected designation on the substitute part provides enhanced regulatory documentation for applications requiring full compliance traceability.

Selection of the VT351AFCX-ADJ eliminates obsolescence risk while preserving electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the VT351AFCX-ADJ directly replace the VT351AFCR-ADJ in existing designs?

A: Yes. Both parts share the same base product number (VT351), identical functional classification (adjustable linear voltage regulator), and equivalent RoHS compliance. No design modifications are required for substitution.

Q: What is the primary difference between these two part numbers?

A: The VT351AFCR-ADJ is obsolete, while the VT351AFCX-ADJ maintains active product status. The substitute part offers improved long-term availability and continued manufacturer support.

Q: Are there packaging differences between the VT351AFCR-ADJ and VT351AFCX-ADJ?

A: Packaging information is not specified in the available technical parameters for either part number. Consult the respective datasheets or contact the manufacturer for detailed package specifications.

Q: Does the VT351AFCX-ADJ meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 Compliant. The VT351AFCX-ADJ additionally carries REACH Unaffected status, providing enhanced regulatory documentation.

Q: Should I prioritize the substitute part over remaining inventory of the obsolete part?

A: For new designs or long-term production, the VT351AFCX-ADJ is recommended due to active product status and supply continuity. Existing inventory of the VT351AFCR-ADJ may be used for current production runs without functional impact.
