Key Parameters

Substitute Part Grouping Explanation

Substitution of the VT273SAFQR is determined by strict alignment of the following parameters:

• Base Product Number: Both the main part and substitute must share the VT273 base designation, ensuring core functional equivalence within the VT273 product family
• Category: Power Management (PMIC) classification must remain consistent
• Product Type: Switching Regulator IC Output functionality must be preserved
• RoHS Compliance: ROHS3 compliance is mandatory for environmental and regulatory compatibility
• Moisture Sensitivity Level: MSL 1 (Unlimited) rating ensures equivalent handling and storage requirements
• REACH Status: REACH Unaffected status must be maintained for supply chain compliance

The VT273SAFQX is identified as a manufacturer-recommended substitute based on these criteria. The primary distinction is product status: VT273SAFQX is active and available, whereas VT273SAFQR is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The VT273SAFQX is the designated manufacturer-recommended substitute for the obsolete VT273SAFQR. Both parts maintain identical compliance certifications (ROHS3 and REACH Unaffected) and equivalent moisture sensitivity ratings. The VT273SAFQX is currently in active production status with confirmed inventory availability (1805 Pcs New Original In Stock), ensuring supply chain continuity for applications previously using the VT273SAFQR.

Selection of VT273SAFQX over VT273SAFQR is driven by product lifecycle status: VT273SAFQR is no longer manufactured, while VT273SAFQX remains actively supported by Analog Devices Inc./Maxim Integrated.

Frequently Asked Questions (FAQ)

Q: Can VT273SAFQX directly replace VT273SAFQR in existing designs?

A: Yes. Both parts share the VT273 base product number, identical PMIC category classification, and equivalent Switching Regulator IC Output functionality. Compliance parameters (ROHS3, MSL 1, REACH Unaffected) are identical, confirming direct substitution compatibility.

Q: Why is VT273SAFQR marked as obsolete?

A: VT273SAFQR has reached end-of-life status in the manufacturer's product lifecycle. The VT273SAFQX is the active equivalent maintained by Analog Devices Inc./Maxim Integrated for ongoing production and support.

Q: Are there packaging differences between VT273SAFQR and VT273SAFQX?

A: Packaging information is not specified in the available technical parameters for either part. Consult the manufacturer's datasheet for detailed package specifications.

Q: What is the inventory status of these parts?

A: VT273SAFQR has 1090 Pcs New Original In Stock (obsolete status). VT273SAFQX has 1805 Pcs New Original In Stock (active status), providing greater supply availability.

Q: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and equivalent handling, storage, and reflow requirements.
