Engineering Selection Recommendations

The VT252AFQX-ADJ is the designated manufacturer-recommended substitute for the obsolete VT252AFQR-ADJ. Selection of this substitute is supported by:

• Active Product Status: The VT252AFQX-ADJ maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Alignment: Both parts satisfy ROHS3 compliance and REACH unaffected requirements, eliminating regulatory substitution barriers
• Identical Compliance Profile: Matching MSL ratings and environmental certifications confirm equivalent handling and deployment requirements
• Manufacturer Endorsement: The substitute is explicitly recommended by Analog Devices Inc./Maxim Integrated as the active equivalent

Frequently Asked Questions (FAQ)

Q: Why is the VT252AFQR-ADJ listed as obsolete? A: The VT252AFQR-ADJ has reached end-of-life status within the manufacturer's product portfolio. The VT252AFQX-ADJ serves as the active continuation of this product line.

Q: Are the VT252AFQR-ADJ and VT252AFQX-ADJ functionally equivalent? A: Both parts share the same base product number (VT252), category classification, and regulatory compliance status. The difference in the suffix designator (R vs. X) reflects manufacturing or packaging variations while maintaining functional equivalence as linear voltage regulator ICs.

Q: What are the key parameters that determine substitution eligibility? A: Substitution is determined by base product number match, manufacturer consistency, identical RoHS and REACH compliance status, and matching moisture sensitivity levels. These parameters ensure electrical and mechanical compatibility.

Q: Are there any handling or storage differences between these parts? A: Both parts carry identical MSL ratings (1 - Unlimited), indicating equivalent moisture sensitivity and storage requirements. No differential handling procedures are necessary.

Q: What inventory considerations should be evaluated? A: The VT252AFQX-ADJ maintains significantly higher inventory levels (4706 units) compared to remaining stock of the obsolete VT252AFQR-ADJ (921 units), supporting improved supply chain reliability for new designs and production requirements.
