Engineering Selection Recommendations
The RMC23MWST serves as the active equivalent for the obsolete AMC23MWST. Selection of the RMC23MWST is supported by the following factors:
Product Status Alignment: The RMC23MWST maintains active production status, ensuring continued component availability and supply chain reliability compared to the obsolete AMC23MWST.
Regulatory Compliance: Both connectors maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments.
Moisture Sensitivity Classification: Identical MSL rating of 1 (Unlimited) indicates equivalent handling and storage requirements, eliminating process modifications during component transition.
Export Classification: The RMC23MWST carries EAR99 classification, providing standard export treatment for commercial connector applications.
Component selection should be based on application-specific requirements for connector configuration, mounting methodology, and electrical performance characteristics as defined by the end-use application.
Frequently Asked Questions (FAQ)
Q: What is the primary reason for substituting the AMC23MWST?
A: The AMC23MWST is classified as obsolete. The RMC23MWST is the active equivalent from the same manufacturer, ensuring continued availability and supply chain continuity.
Q: Are the AMC23MWST and RMC23MWST mechanically compatible?
A: Both connectors are manufactured by Sullins Connector Solutions and share the same base product number series (AMC23 and RMC23 respectively). Mechanical compatibility is determined by application-specific mounting and card edge interface requirements.
Q: Do both connectors meet current regulatory standards?
A: Yes. Both the AMC23MWST and RMC23MWST are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
Q: What is the significance of the MSL rating for these connectors?
A: Both connectors carry MSL 1 (Unlimited) classification, indicating they do not require moisture-sensitive device handling procedures. Standard storage and handling practices are applicable.
Q: Can the RMC23MWST be used as a direct replacement in existing designs?
A: The RMC23MWST qualifies as a substitute based on shared manufacturer, connector category, position count, row configuration, and pitch specification. Design validation should confirm compatibility with specific application requirements including mounting type, termination method, and electrical performance criteria.
Q: What export classification applies to the RMC23MWST?
A: The RMC23MWST carries EAR99 classification, which is the standard export control classification for commercial connector products.
