Key Parameters

Substitute Part Grouping Explanation

Substitution of the VT1115SCX is determined by alignment across the following critical parameters:

• Manufacturer & Product Line: Both the main part and substitute must originate from Analog Devices Inc./Maxim Integrated to ensure design compatibility and support continuity.
• Functional Category: Both components must operate within the Power Management (PMIC) classification as switching regulator ICs.
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be maintained to satisfy environmental and regulatory requirements.
• Moisture Sensitivity: MSL rating of 1 (unlimited) ensures equivalent handling and storage requirements.

The VT1115SFCX qualifies as a direct substitute based on these parameters. It shares the same manufacturer, functional category, and regulatory compliance profile while offering active product status, ensuring long-term availability and support.

Parameter Comparison

Engineering Selection Recommendations

The VT1115SFCX is the qualified substitute for the obsolete VT1115SCX. Selection of this alternative is justified on the following engineering grounds:

• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory mandates without modification to design documentation.
• Product Lifecycle Status: The VT1115SFCX holds active product status, ensuring continued manufacturing support, availability, and technical documentation from Analog Devices Inc./Maxim Integrated.
• Equivalent Handling Requirements: Identical MSL rating (1, unlimited) ensures no changes to component storage, handling, or assembly processes.
• Manufacturer Continuity: Both parts originate from the same manufacturer, maintaining design support and technical consistency.

Frequently Asked Questions (FAQ)

Q: Why is the VT1115SCX being phased out? A: The VT1115SCX is classified as obsolete by the manufacturer. The VT1115SFCX provides functional equivalence while maintaining active product status and long-term availability.

Q: Are there any design changes required when switching from VT1115SCX to VT1115SFCX? A: No design changes are required. Both components share identical regulatory compliance, moisture sensitivity ratings, and manufacturer support. Substitution is direct at the component level.

Q: What is the difference between the base product numbers VT1115S and VT1115? A: The base product numbers reflect different product variants within the Analog Devices Inc./Maxim Integrated switching regulator family. The VT1115SFCX (base VT1115) represents the active, current-generation equivalent to the obsolete VT1115SCX (base VT1115S).

Q: Are packaging specifications identical between these parts? A: Packaging information was not provided in the technical specifications for either component. Verify packaging compatibility through the manufacturer's datasheet before final design implementation.

Q: Does substitution affect RoHS or REACH compliance? A: No. Both components maintain ROHS3 compliance and REACH unaffected status. Substitution does not alter the regulatory compliance profile of the design.

Q: What inventory considerations should be evaluated? A: The VT1115SFCX maintains significantly higher inventory availability (17,853 pcs) compared to the obsolete VT1115SCX (4,969 pcs), supporting production continuity and supply chain stability.
