Substitute Part Grouping Explanation

Substitution of the VT2491FCR-ADJ is based on the following criteria derived from the provided parameters:

• Manufacturer Alignment: Substitute must be from Analog Devices Inc./Maxim Integrated to ensure design compatibility and performance consistency
• Product Category: Substitute must function as a Power Management (PMIC) linear voltage regulator
• Base Product Number: Substitute must share the VT2491 base product number, indicating functional equivalence within the product family
• Regulatory Compliance: Substitute must maintain ROHS3 compliance and REACH Unaffected status to meet environmental and regulatory requirements
• Functional Classification: Substitute must be a single-output linear voltage regulator IC

The VT2491FCX-ADJ meets all substitution criteria as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The VT2491FCX-ADJ is the manufacturer-recommended substitute for the obsolete VT2491FCR-ADJ. Both components share identical manufacturer origin, product category classification, and base product number, establishing functional equivalence.

The VT2491FCX-ADJ maintains full regulatory compliance with ROHS3 and REACH Unaffected status, matching the environmental requirements of the original component. The substitute exhibits improved moisture sensitivity characteristics (MSL 1 versus MSL 3), providing enhanced reliability during storage and handling.

The active product status of the VT2491FCX-ADJ ensures continued availability, technical support, and supply chain stability compared to the obsolete original component. Selection of the VT2491FCX-ADJ is appropriate for new designs, redesigns, and production continuity applications.

Frequently Asked Questions (FAQ)

Q: Why is the VT2491FCR-ADJ obsolete? A: The VT2491FCR-ADJ has reached end-of-life status. The VT2491FCX-ADJ is the active equivalent within the same product family.

Q: What is the primary difference between VT2491FCR-ADJ and VT2491FCX-ADJ? A: Both components share the same base product number and manufacturer. The primary difference is product status: VT2491FCR-ADJ is obsolete, while VT2491FCX-ADJ is active. The VT2491FCX-ADJ also features improved moisture sensitivity (MSL 1 versus MSL 3).

Q: Are both parts ROHS3 compliant? A: Yes, both the VT2491FCR-ADJ and VT2491FCX-ADJ are ROHS3 compliant and REACH Unaffected.

Q: What does MSL 1 versus MSL 3 mean for component handling? A: MSL 3 (168 Hours) indicates the component must be used within 168 hours of moisture exposure. MSL 1 (Unlimited) indicates no time restriction, providing greater flexibility in storage and handling procedures.

Q: Is the VT2491FCX-ADJ suitable for new designs? A: Yes, the VT2491FCX-ADJ is the active product and is appropriate for new designs requiring a single-output linear voltage regulator from Analog Devices Inc./Maxim Integrated.
