AMC52MSST Equivalent & Substitute Parts

Part Overview

The AMC52MSST is a 104-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards at 0.100" (2.54mm) pitch. This connector features dual read-out configuration with beryllium copper contacts finished in gold plating. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to support ongoing system maintenance and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC52MSST is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector category: Card Edge Connectors
• Position count: 104 positions
• Row configuration: 2 rows
• Pitch specification: 0.100" (2.54mm)
• Manufacturer: Sullins Connector Solutions
• Product status: Active (non-obsolete)
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected, MSL 1

The RMC52MSST qualifies as a direct substitute based on shared manufacturer lineage (Sullins Connector Solutions), identical base product number derivation (RMC52 vs. AMC52), and active product status enabling continued supply chain support.

Parameter Comparison

Engineering Selection Recommendations

The RMC52MSST is the appropriate substitute for the obsolete AMC52MSST based on the following engineering factors:

Regulatory Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements for electronic component procurement.

Supply Chain Continuity: The RMC52MSST holds active product status with documented inventory availability (779 pieces), whereas the AMC52MSST is classified as obsolete. Selection of the active substitute ensures long-term supply chain reliability and eliminates obsolescence risk.

Manufacturer Consistency: Both connectors originate from Sullins Connector Solutions, maintaining design lineage and manufacturing process consistency. The shared base product number structure (AMC52 to RMC52) indicates evolutionary product development within the same connector family.

Moisture and Environmental Classification: Identical MSL 1 rating confirms equivalent handling and storage requirements, with no additional moisture sensitivity constraints introduced by substitution.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC52MSST?

A: The AMC52MSST is classified as obsolete. The RMC52MSST provides an active alternative from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are the AMC52MSST and RMC52MSST mechanically compatible?

A: Both connectors are 104-position, 2-row card edge connectors manufactured by Sullins Connector Solutions. Mechanical compatibility is established through shared connector category classification and base product number lineage.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the AMC52MSST and RMC52MSST are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: What is the difference between the ECCN classifications?

A: The AMC52MSST carries an obsolete ECCN designation, while the RMC52MSST is classified as EAR99. The EAR99 classification for the substitute part reflects its active status and current export control assessment.

Q: Are there any moisture sensitivity differences between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and equivalent handling requirements.

Q: Can the RMC52MSST be used as a direct replacement in existing designs?

A: The RMC52MSST qualifies as a substitute based on shared manufacturer, connector category, and regulatory compliance. Design validation should confirm mechanical and electrical interface compatibility with specific application requirements.

Q: What inventory status should be considered for procurement decisions?

A: The RMC52MSST has 779 pieces in stock as new original inventory, providing immediate availability. The AMC52MSST, though 1066 pieces are listed, is obsolete and should not be selected for new designs or long-term production planning.
