Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC48MSST is based on the following critical parameters that define functional equivalence within the card edge connector category:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer ensures design compatibility)
• Position Count: 96 positions (electrical interface requirement)
• Row Configuration: 2 rows (physical and electrical layout)
• Pitch: 0.100" (2.54mm) (mechanical interchangeability with female edgecards)
• Gender: Male (connector orientation and mating interface)
• Card Type: Fits Female Edgecards (application compatibility)
• Read Out: Dual (signal access configuration)

Compliance Parameters:

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

The RMC48MSST is identified as a direct substitute based on shared manufacturer origin and base product number (RMC48 vs. AMC48), indicating design family continuity within Sullins Connector Solutions' product line.

Engineering Selection Recommendations

The RMC48MSST is the appropriate substitute for the obsolete AMC48MSST based on the following engineering considerations:

Product Status Alignment: The RMC48MSST maintains active product status with Sullins Connector Solutions, ensuring ongoing availability, technical support, and supply chain continuity. The AMC48MSST's obsolete classification creates procurement risk for new production and field service requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and material restriction requirements. Moisture sensitivity level equivalence (MSL 1) ensures identical storage, handling, and packaging requirements.

Manufacturer Continuity: Both connectors originate from Sullins Connector Solutions, with related base product numbers (AMC48 and RMC48) indicating design family relationship and engineering compatibility within the manufacturer's card edge connector portfolio.

Export Classification: The RMC48MSST carries EAR99 classification, providing standard export control treatment compared to the obsolete designation of the original part.

Selection of the RMC48MSST eliminates obsolescence risk while maintaining compliance requirements and manufacturer-backed technical support.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC48MSST?

A: The AMC48MSST is classified as obsolete. The RMC48MSST is the active equivalent from the same manufacturer, ensuring continued availability and supply chain reliability for new production and field service applications.

Q: Are the AMC48MSST and RMC48MSST mechanically interchangeable?

A: Both connectors are manufactured by Sullins Connector Solutions and share the same base product family designation (AMC48 and RMC48 respectively). The RMC48MSST is designed as the active replacement within the product line.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AMC48MSST and RMC48MSST are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level 1 (Unlimited) ratings, satisfying equivalent environmental and material compliance standards.

Q: What is the difference in ECCN classification between these parts?

A: The AMC48MSST carries an obsolete ECCN designation, while the RMC48MSST is classified as EAR99. The RMC48MSST's EAR99 classification provides standard export control treatment applicable to most commercial electronic components.

Q: Can the RMC48MSST be used in existing designs specified for the AMC48MSST?

A: The RMC48MSST is the designated active substitute from Sullins Connector Solutions for the obsolete AMC48MSST. Design compatibility is established through the manufacturer's product family relationship and equivalent compliance certifications.

Q: What inventory status should be considered when selecting between these parts?

A: The AMC48MSST has 648 pieces in stock as new original inventory. The RMC48MSST has 770 pieces in stock. However, the AMC48MSST's obsolete status means existing inventory represents a finite supply, while the RMC48MSST's active status ensures ongoing procurement availability.
