Substitute Part Grouping Explanation

Substitute parts for the VT263ABWFQR-ADJ are identified based on the following criteria:

Manufacturer Alignment: Parts must originate from Analog Devices Inc./Maxim Integrated to ensure design consistency and support continuity.

Base Product Series: Substitutes share the VT263 base product number, indicating membership in the same product family with compatible pinouts and functional characteristics.

Regulatory Compliance: Both the original part and substitutes maintain ROHS3 compliance and REACH Unaffected status, ensuring environmental and regulatory compatibility.

Moisture Sensitivity: Matching MSL rating of 3 (168 Hours) ensures equivalent handling, storage, and assembly process requirements.

Product Status Transition: The substitute part transitions from obsolete to active status, providing continued component availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The VT263ABWFQX-ADJ serves as the manufacturer-recommended substitute for the obsolete VT263ABWFQR-ADJ. Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected) and equivalent moisture sensitivity ratings, ensuring compatibility with existing assembly and storage protocols.

The substitute part's active product status provides assured long-term availability and continued manufacturer technical support. The higher inventory level (7124 Pcs versus 994 Pcs) indicates stronger supply chain stability for the substitute part.

Selection between these parts should be based on circuit design requirements specific to linear versus switching regulator topologies, as the device type differs between the original and substitute configurations.

Frequently Asked Questions (FAQ)

Q: Can the VT263ABWFQX-ADJ directly replace the VT263ABWFQR-ADJ in existing designs?

A: Both parts share the VT263 base product number and identical compliance ratings. However, the original part is a linear voltage regulator while the substitute is a switching regulator. Direct substitution requires verification that the circuit design accommodates the switching topology.

Q: What is the significance of the product status change from obsolete to active?

A: The active status of the substitute part ensures continued manufacturer support, availability of technical documentation, and reliable supply chain access. Obsolete parts face eventual discontinuation and supply constraints.

Q: Are the moisture sensitivity and handling requirements identical?

A: Yes. Both parts carry MSL rating 3 (168 Hours), requiring identical storage conditions, handling procedures, and assembly process parameters.

Q: Does the substitute part maintain the same regulatory compliance?

A: Yes. Both parts are ROHS3 compliant and REACH Unaffected, ensuring equivalent environmental and regulatory compatibility.

Q: What does the base product number VT263 indicate?

A: The base product number identifies membership in the same product family, indicating compatible pinouts and functional characteristics within the Analog Devices Inc./Maxim Integrated power management portfolio.
