Key Parameters

Substitute Part Grouping Explanation

Substitution for obsolete DC/DC converter models is carried out strictly based on the following allowed parameters: manufacturer part number, manufacturer, product status, RoHS compliance, moisture sensitivity level (MSL), REACH status, description, packaging, and inventory. Only parts that match these compliance and availability requirements are grouped as direct substitutes.

Key parameters for substitution:

• Product status: must be active or available for ongoing applications
• RoHS Status: must be ROHS3 compliant
• Moisture Sensitivity Level (MSL): must be 1 (Unlimited)
• REACH Status: must be unaffected
• Manufacturer: must match, ensuring mechanical compatibility
• Packaging and inventory are considered for logistics and supply continuity
