Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC56MSST is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer ensures design compatibility)
• Number of Positions: 112 positions (functional requirement for circuit board interface)
• Number of Rows: 2 rows (physical configuration requirement)
• Pitch: 0.100" (2.54mm) (mechanical spacing standard)
• Contact Material: Beryllium Copper (electrical performance and reliability)
• Contact Finish: Gold (corrosion resistance and signal integrity)
• RoHS Status: ROHS3 Compliant (regulatory compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (storage and handling compatibility)

The RMC56MSST is identified as a direct manufacturer substitute, produced by the same manufacturer and sharing the same base product number (RMC56 vs. AMC56), indicating design lineage and functional equivalence within the Sullins connector portfolio.

Parameter Comparison

Engineering Selection Recommendations

The RMC56MSST is the appropriate substitute for the obsolete AMC56MSST based on the following engineering factors:

Product Status Alignment: The RMC56MSST maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity. The AMC56MSST, classified as obsolete, presents procurement risk and potential discontinuation of manufacturing support.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement. The RMC56MSST carries EAR99 export classification, providing broader distribution flexibility compared to the obsolete designation of the original part.

Manufacturer Continuity: Both connectors originate from Sullins Connector Solutions, with the RMC56 base product number indicating direct product line succession. This manufacturer relationship ensures design compatibility and consistent electrical and mechanical performance characteristics.

Compliance Certifications: Identical MSL rating (1 - Unlimited) ensures equivalent handling, storage, and environmental performance without modification to existing logistics or assembly procedures.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC56MSST?

A: The AMC56MSST is classified as obsolete, indicating discontinued manufacturing and potential supply unavailability. The RMC56MSST is an active product from the same manufacturer, ensuring continued procurement and manufacturing support.

Q: Are the AMC56MSST and RMC56MSST mechanically compatible?

A: Both connectors are 112-position, 2-row card edge connectors manufactured by Sullins Connector Solutions with 0.100" (2.54mm) pitch. The shared base product number lineage (AMC56 to RMC56) indicates design compatibility within the manufacturer's product portfolio.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the AMC56MSST and RMC56MSST are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory standards for electronic component procurement.

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

A: The AMC56MSST carries an obsolete ECCN designation, while the RMC56MSST is classified as EAR99. The EAR99 classification of the substitute part provides standard export treatment and broader distribution flexibility.

Q: Are there any differences in moisture sensitivity or storage requirements?

A: No. Both parts carry identical MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions and identical handling, storage, and assembly requirements.

Q: Can the RMC56MSST be used as a direct replacement in existing designs?

A: The RMC56MSST shares critical electrical and mechanical parameters with the AMC56MSST, including connector type, position count, pitch, contact material, and finish specifications. Design validation should confirm compatibility with specific application requirements.
