Engineering Selection Recommendations

The RMC45MWST serves as the active substitute for the obsolete AMC45MWST. Both components are manufactured by Sullins Connector Solutions and share identical RoHS3 compliance and REACH regulatory status. The substitute part maintains MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling.

Selection of the RMC45MWST is appropriate for applications requiring 90-position, 2-row card edge connector functionality at 0.100" pitch. The active product status of the RMC45MWST ensures continued manufacturing availability, technical support, and supply chain reliability compared to the obsolete AMC45MWST.

Both components satisfy equivalent regulatory and environmental compliance requirements. The transition from AMC45MWST to RMC45MWST does not introduce additional moisture sensitivity or temperature operating constraints.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC45MWST?

A: The AMC45MWST is classified as obsolete. The RMC45MWST is the active equivalent from Sullins Connector Solutions, ensuring continued product availability and manufacturing support.

Q: Are the AMC45MWST and RMC45MWST electrically compatible?

A: Both components are 90-position, 2-row male card edge connectors manufactured by Sullins Connector Solutions. Electrical compatibility is established through shared design family lineage (AMC45 base product vs. RMC45 base product).

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AMC45MWST and RMC45MWST are ROHS3 compliant and REACH unaffected. Both maintain MSL Level 1 rating with unlimited moisture sensitivity tolerance.

Q: What is the pitch specification for these connectors?

A: The AMC45MWST operates at 0.100" (2.54mm) pitch. This specification is standard for the 90-position, 2-row configuration.

Q: Are there any temperature operating differences between the two parts?

A: The AMC45MWST operates across -65°C to 200°C. Specific operating temperature data for the RMC45MWST is not provided in the substitute component specifications.

Q: What contact material and finish are used in these connectors?

A: The AMC45MWST features beryllium copper contacts with gold plating at 30.0µin (0.76µm) thickness. Contact material and finish specifications for the RMC45MWST are not provided in the available data.

Q: Is the RMC45MWST available in stock?

A: The RMC45MWST is listed as active product status with 813 pieces in new original stock inventory.
