Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC20MWST is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector category: Card Edge Connectors
• Number of positions: 40
• Number of rows: 2
• Pitch specification: 0.100" (2.54mm)
• Manufacturer: Sullins Connector Solutions
• Product status: Active availability

The RMC20MWST qualifies as a direct substitute based on shared base product number (RMC20 vs. AMC20 series designation), identical position count and row configuration, and active product status. Both components are manufactured by Sullins Connector Solutions and maintain ROHS3 compliance and MSL 1 classification, ensuring regulatory and environmental consistency.

Parameter Comparison

Engineering Selection Recommendations

The RMC20MWST is the appropriate substitute for the obsolete AMC20MWST based on the following factors:

Product Status Alignment: The AMC20MWST is classified as obsolete, creating supply chain constraints. The RMC20MWST maintains active product status with confirmed inventory availability (1065 pieces in stock), ensuring procurement reliability for current and future applications.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements without modification to design specifications or procurement procedures.

Moisture Sensitivity Classification: Both parts carry MSL 1 (Unlimited) classification, indicating identical handling and storage requirements with no moisture sensitivity constraints.

Manufacturer Continuity: Both connectors are manufactured by Sullins Connector Solutions, maintaining design consistency and quality standards within the same product family.

Selection of the RMC20MWST eliminates obsolescence risk while preserving compliance certifications and environmental classifications required for production and deployment.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC20MWST?

A: The AMC20MWST is classified as obsolete, limiting procurement availability. The RMC20MWST provides an active alternative from the same manufacturer with confirmed inventory stock.

Q: Are the AMC20MWST and RMC20MWST mechanically compatible?

A: Both connectors are 40-position, 2-row card edge connectors manufactured by Sullins Connector Solutions with 0.100" (2.54mm) pitch specification. The shared base product family (AMC20 and RMC20 series) indicates mechanical compatibility within the connector interface design.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AMC20MWST and RMC20MWST are ROHS3 compliant and REACH unaffected, satisfying identical environmental and regulatory compliance standards.

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

A: Both components carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints and identical handling requirements.

Q: Is there a difference in operating temperature range between the two parts?

A: The operating temperature range for the AMC20MWST is specified as -65°C ~ 200°C. The operating temperature range for the RMC20MWST is not provided in the available technical data.

Q: Can the RMC20MWST be used as a direct replacement in existing designs?

A: The RMC20MWST shares the same connector category, position count, row configuration, pitch specification, and manufacturer as the AMC20MWST. Compatibility determination requires verification of specific application requirements and interface specifications not provided in this reference data.

Q: What inventory levels are available for each part?

A: The AMC20MWST has 993 pieces in stock (obsolete status). The RMC20MWST has 1065 pieces in stock (active status).
