Substitute Part Grouping Explanation

Substitution of the AMC42MSST is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer ensures design compatibility)
• Category: Card Edge Connectors (functional category match)
• Number of Positions: 84 (electrical interface requirement)
• Number of Rows: 2 (physical configuration requirement)
• Pitch: 0.100" (2.54mm) (contact spacing requirement)
• Gender: Male (connector orientation requirement)
• Read Out: Dual (signal access configuration)

Secondary Compliance Criteria:

• RoHS3 Compliance (regulatory requirement)
• Moisture Sensitivity Level 1 (handling and storage requirement)
• REACH Unaffected (regulatory requirement)

The RMC42MSST is identified as a direct substitute based on manufacturer continuity and base product number alignment (RMC42 vs. AMC42), indicating functional equivalence within the Sullins connector product line.

Parameter Comparison

Engineering Selection Recommendations

The RMC42MSST is the appropriate substitute for the obsolete AMC42MSST based on the following engineering factors:

Product Status Alignment: The RMC42MSST maintains active product status with Sullins Connector Solutions, ensuring continued availability, technical support, and manufacturing consistency. The AMC42MSST obsolete classification creates supply chain risk and limits access to replacement inventory.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. The RMC42MSST carries EAR99 export classification, providing broader distribution flexibility compared to the obsolete designation of the original part.

Manufacturer Continuity: Selection of the RMC42MSST from the same manufacturer (Sullins Connector Solutions) ensures design compatibility, consistent manufacturing standards, and alignment with the original connector family specifications.

Compliance Certifications: Both components share identical Moisture Sensitivity Level 1 classification, indicating equivalent handling, storage, and environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC42MSST?

A: The AMC42MSST is classified as obsolete. The RMC42MSST is an active product from the same manufacturer that provides functional equivalence while ensuring ongoing component availability and manufacturer support.

Q: Are the AMC42MSST and RMC42MSST mechanically compatible?

A: Both connectors are 84-position, 2-row card edge connectors manufactured by Sullins Connector Solutions with 0.100" (2.54mm) pitch. The RMC42 base product number indicates functional equivalence within the Sullins connector product line.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the AMC42MSST and RMC42MSST are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 classification, meeting current environmental and regulatory standards.

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

A: The AMC42 series is obsolete, while the RMC42 series is active. Both are manufactured by Sullins Connector Solutions as card edge connectors. The RMC42MSST represents the current active equivalent within the manufacturer's product portfolio.

Q: Are there any handling or storage differences between these components?

A: No. Both components carry identical Moisture Sensitivity Level 1 classification, indicating equivalent handling, storage, and environmental performance requirements.

Q: Can the RMC42MSST be used as a direct replacement in existing designs?

A: The RMC42MSST shares the same connector category, position count, row configuration, and pitch as the AMC42MSST. Verification of specific design requirements and mechanical mounting characteristics is necessary to confirm direct replacement suitability.
