Substitute Part Grouping Explanation

Substitution of the VT261WFQR-ADJ is determined by the following criteria:

Functional Equivalence: Both the main part and substitute must operate as Switching Regulator IC Output components within the Power Management (PMIC) category.

Manufacturer Consistency: The substitute part must originate from the same manufacturer (Analog Devices Inc./Maxim Integrated) to ensure design compatibility and performance alignment.

Base Product Series: The substitute must share the same base product number (VT261) to confirm core functional architecture.

Compliance Requirements: The substitute must maintain ROHS3 compliance to satisfy regulatory and procurement standards.

Product Status Consideration: The substitute part must be in Active production status to ensure long-term availability and supply chain viability.

The VT261WFQX-ADJ meets all substitution criteria as an active equivalent within the VT261 product family.

Engineering Selection Recommendations

For New Designs: The VT261WFQX-ADJ is the appropriate selection. This part maintains Active product status, ensuring manufacturer support, continued availability, and compliance with current regulatory requirements. Both ROHS3 compliance certifications confirm environmental and safety standard adherence.

For Legacy System Support: The VT261WFQR-ADJ remains available in current inventory (10,297 pieces). However, due to Obsolete designation, long-term procurement cannot be guaranteed. Transition planning to the VT261WFQX-ADJ is recommended for sustained production support.

Compliance Verification: Both parts satisfy ROHS3 requirements. The VT261WFQX-ADJ additionally carries REACH Unaffected status, providing enhanced regulatory documentation for international applications.

Frequently Asked Questions (FAQ)

Q: Can the VT261WFQX-ADJ directly replace the VT261WFQR-ADJ in existing designs?

A: Yes. Both parts share the same base product number (VT261), operate as Switching Regulator IC Output components, originate from the same manufacturer, and maintain identical RoHS3 compliance. The functional architecture remains consistent across the product family.

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

A: The VT261WFQR-ADJ is designated Obsolete, while the VT261WFQX-ADJ maintains Active production status. The packaging designation differs (QFN SMD for the substitute), but both deliver equivalent switching regulator functionality.

Q: Are there packaging considerations when substituting these parts?

A: Packaging information is not fully specified in the available parameters for the VT261WFQR-ADJ. The VT261WFQX-ADJ is identified as QFN SMD package. PCB layout and footprint compatibility must be verified against your specific design documentation.

Q: Does the VT261WFQX-ADJ carry additional compliance certifications?

A: Yes. The VT261WFQX-ADJ includes REACH Unaffected status in addition to ROHS3 compliance, providing broader regulatory coverage for international markets and supply chain requirements.

Q: What inventory considerations apply to these parts?

A: The VT261WFQR-ADJ has 10,297 pieces in current stock. The VT261WFQX-ADJ has 1,900 pieces available. Given the Obsolete status of the main part, inventory of the substitute may provide more reliable long-term availability.
