Substitute Part Grouping Explanation
Substitution of the AMC21MWST is based on maintaining compatibility within the Sullins Connector Solutions card edge connector family. The primary substitute identified is the RMC21MWST, which shares the same base product number designation (RMC21 vs. AMC21) and is manufactured by the same supplier.
The substitution logic is established through the following criteria:
- Manufacturer Consistency: Both parts are manufactured by Sullins Connector Solutions, ensuring design and quality standards alignment
- Connector Category: Both are classified as card edge connectors
- Base Product Family: The RMC21 designation indicates membership in the same connector family as the AMC21
- Compliance Certifications: Both parts maintain ROHS3 compliance and REACH unaffected status
- Moisture Sensitivity: Both parts share MSL 1 (Unlimited) classification
The RMC21MWST is classified as active product status, providing ongoing availability and support compared to the obsolete AMC21MWST.
