Substitute Part Grouping Explanation

Substitution of the obsolete VT503FQ is determined by the following criteria:

Manufacturer Alignment: Both the main part and substitute must originate from Analog Devices Inc./Maxim Integrated to ensure design consistency and support continuity.

Compliance Requirements: Substitute parts must maintain ROHS3 compliance and REACH Unaffected status to satisfy regulatory and environmental standards equivalent to the original component.

Moisture Sensitivity: Substitute parts must have Moisture Sensitivity Level 1 (Unlimited) to match the original part's handling and storage requirements.

Product Status: Active product status in substitute parts ensures ongoing availability, technical support, and manufacturing continuity.

The identified substitute MAX16543GPC+ meets these substitution criteria while providing an active alternative to the obsolete VT503FQ.
