Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC49MSST 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)
• Pitch: 0.100" (2.54mm) (electrical and mechanical interface requirement)
• Number of Rows: 2 (physical configuration requirement)
• Contact Material: Beryllium Copper (electrical performance and reliability)
• Contact Finish: Gold (corrosion resistance and signal integrity)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)
• REACH Status: REACH Unaffected (regulatory compliance)

The RMC49MSST is identified as a direct manufacturer substitute from Sullins Connector Solutions. This part maintains the same base product family designation (RMC49 vs. AMC49) and shares the same connector pitch and row configuration. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The RMC49MSST is the appropriate substitute for the obsolete AMC49MSST based on the following engineering considerations:

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

Supply Chain Continuity: The RMC49MSST is classified as an active product with documented inventory availability (909 pieces in stock), providing immediate access and long-term procurement stability compared to the obsolete AMC49MSST.

Manufacturer Consistency: Both connectors are manufactured by Sullins Connector Solutions, ensuring design philosophy alignment, quality standards, and technical support continuity.

Moisture Sensitivity: Both parts share identical MSL classification (1 - Unlimited), indicating equivalent handling, storage, and environmental requirements throughout the component lifecycle.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC49MSST?

A: The AMC49MSST is classified as obsolete. The RMC49MSST provides an active, in-stock alternative from the same manufacturer, ensuring continued availability and supply chain reliability.

Q: Are the pitch and row configurations identical between the main part and substitute?

A: Both the AMC49MSST and RMC49MSST are designed for 0.100" (2.54mm) pitch card edge connector applications with 2-row configurations, maintaining mechanical and electrical interface compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the AMC49MSST and RMC49MSST are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing.

Q: What is the significance of the base product number change from AMC49 to RMC49?

A: The base product number change indicates a product line evolution within Sullins Connector Solutions' card edge connector portfolio. Both designations represent the same functional connector family with equivalent electrical and mechanical specifications.

Q: Are there any differences in contact material or finish specifications?

A: The provided specifications for the RMC49MSST do not include detailed contact material and finish data. For applications requiring specific contact material verification (beryllium copper) or finish thickness confirmation (30.0µin gold), direct consultation with Sullins Connector Solutions technical documentation is necessary.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or deployment in standard industrial environments.
