Substitute Part Grouping Explanation

Substitution for the VT252FQR-ADJ is determined by the following criteria:

• Manufacturer Continuity: Both the main part and substitute maintain the same manufacturer (Analog Devices Inc./Maxim Integrated)
• Base Product Series: Both parts share the VT252 base product number, ensuring functional equivalence within the same product line
• Functional Category: Both are classified as linear voltage regulator ICs within the Power Management (PMIC) category
• Compliance Standards: Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment
• Moisture Sensitivity: Both maintain MSL 1 (Unlimited) rating for storage and handling compatibility

The VT252FQX-ADJ serves as the active production equivalent to the obsolete VT252FQR-ADJ, with the primary distinction being product status transition from obsolete to active.
