Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC42MWST is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector category: Card Edge Connectors
• Position count: 84 positions
• Row configuration: 2 rows
• Pitch specification: 0.100" (2.54mm)
• Gender: Male
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected
• Moisture sensitivity: MSL 1 (Unlimited)

The RMC42MWST is identified as a direct manufacturer substitute from Sullins Connector Solutions. Both components share the same base product number designation (42-position per row configuration) and maintain identical regulatory compliance status. The substitute part is currently in active production status, providing continuity for applications previously utilizing the obsolete AMC42MWST.

Parameter Comparison

Engineering Selection Recommendations

The RMC42MWST is the direct substitute for the obsolete AMC42MWST. Both components are manufactured by Sullins Connector Solutions and maintain identical regulatory compliance certifications under ROHS3 and REACH standards. The substitute part carries active product status, ensuring availability for procurement and technical support.

Selection of the RMC42MWST is appropriate for applications requiring replacement of failed AMC42MWST units or for new designs transitioning from the obsolete part number. The active status of the substitute part provides supply chain continuity and eliminates obsolescence risk associated with the original component.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC42MWST?

A: The AMC42MWST is classified as obsolete. The RMC42MWST is the active equivalent from the same manufacturer, providing continued availability and supply chain support.

Q: Are the AMC42MWST and RMC42MWST electrically compatible?

A: Both components are 84-position male card edge connectors manufactured by Sullins Connector Solutions with 0.100" (2.54mm) pitch and dual read-out configuration, meeting the electrical requirements for card edge connector applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AMC42MWST and RMC42MWST are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the difference between the AMC42 and RMC42 base product designations?

A: The base product numbers indicate different product lines within the Sullins card edge connector portfolio. The RMC42 represents the active production line that supersedes the obsolete AMC42 line.

Q: Can the RMC42MWST be used as a direct replacement in existing assemblies?

A: The RMC42MWST is designed as a direct substitute for the AMC42MWST. Mechanical and electrical compatibility is maintained for card edge connector applications requiring 84-position, 2-row, 0.100" pitch male connectors.

Q: What is the ECCN classification difference between the two parts?

A: The AMC42MWST carries an OBSOLETE ECCN designation, while the RMC42MWST is classified as EAR99. The EAR99 classification for the substitute part reflects its active commercial status.
