Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC56MWST is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector category: Card Edge Connectors
• Position count: 112 positions
• Row configuration: 2 rows
• Pitch specification: 0.100" (2.54mm)
• Gender: Male
• Manufacturer: Sullins Connector Solutions (same manufacturer ensures design compatibility)

Compliance & Regulatory Criteria:

• RoHS3 compliance status
• REACH regulatory status
• Moisture Sensitivity Level (MSL) rating

The RMC56MWST qualifies as a direct substitute based on manufacturer continuity within the Sullins connector family and shared base product designation (RMC56 vs. AMC56). The substitute part maintains active product status, ensuring ongoing availability and support for applications currently utilizing the obsolete AMC56MWST.

Parameter Comparison

Engineering Selection Recommendations

The RMC56MWST serves as the active substitute for the obsolete AMC56MWST. Selection of the RMC56MWST is supported by the following factors:

Product Status: The RMC56MWST maintains active product status with current manufacturing and inventory availability (1092 pieces in stock), whereas the AMC56MWST is obsolete with no ongoing production.

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

Moisture Sensitivity: Both parts carry MSL rating of 1 (Unlimited), indicating identical handling and storage requirements.

Manufacturer Continuity: Both connectors are manufactured by Sullins Connector Solutions, ensuring design consistency and connector family compatibility.

Connector Specifications: Both parts share the same 112-position, 2-row configuration at 0.100" (2.54mm) pitch, maintaining mechanical and electrical interface compatibility with existing female edgecard receptacles.

Frequently Asked Questions (FAQ)

Q: Can the RMC56MWST directly replace the AMC56MWST in existing applications?

A: The RMC56MWST is designed as a direct substitute for the obsolete AMC56MWST. Both connectors share identical position count (112), row configuration (2 rows), and pitch specification (0.100" / 2.54mm), ensuring compatibility with female edgecard receptacles designed for the original part.

Q: What is the primary reason for substitution?

A: The AMC56MWST is classified as obsolete with no ongoing production. The RMC56MWST is the active equivalent from the same manufacturer, ensuring continued availability and support for applications requiring 112-position card edge connectors.

Q: Are there differences in regulatory compliance between the two parts?

A: No. Both the AMC56MWST and RMC56MWST maintain identical ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory standing for current applications.

Q: What are the moisture sensitivity requirements for both parts?

A: Both connectors carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special environmental controls.

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

A: The AMC56MWST specifies beryllium copper contacts with gold finish at 30.0µin (0.76µm) thickness. Equivalent contact specifications for the RMC56MWST are not provided in available documentation. Contact material and finish details should be confirmed through the manufacturer's current technical datasheet for the RMC56MWST.

Q: What is the operating temperature range for the substitute part?

A: The AMC56MWST operates across -65°C to 200°C. Operating temperature specifications for the RMC56MWST are not provided in available documentation and should be verified through the manufacturer's current technical specifications.

Q: How does the base product number relate to substitution?

A: The AMC56MWST carries base product number AMC56, while the RMC56MWST carries base product number RMC56. Both designations indicate related product families within the Sullins connector portfolio, with the RMC56 series representing the current active generation.
