Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC27MWST is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer maintains design compatibility)
• Category: Card Edge Connectors (functional category match)
• Number of Positions: 54 positions (electrical interface requirement)
• Number of Rows: 2 rows (physical configuration requirement)
• Pitch: 0.100" (2.54mm) (contact spacing standard)
• Gender: Male (connector orientation)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)
• REACH Status: REACH Unaffected (environmental compliance)

The RMC27MWST qualifies as a direct substitute based on shared manufacturer origin and base product number (RMC27 vs. AMC27), indicating design family continuity within the Sullins connector portfolio. The substitute part maintains active product status, ensuring ongoing availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: The RMC27MWST is the appropriate selection for new applications. This part maintains active product status with Sullins Connector Solutions, ensuring long-term availability, manufacturing consistency, and technical support. Both parts carry identical RoHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

For Existing Inventory and Field Service: The AMC27MWST remains available in current stock (660 pieces). Transition planning to the RMC27MWST is recommended for applications entering production phases, as the substitute part offers superior supply chain continuity and manufacturing support.

Compliance Considerations: Both parts satisfy ROHS3 and REACH requirements. The RMC27MWST carries EAR99 export classification, providing broader distribution flexibility compared to the obsolete classification of the AMC27MWST.

Frequently Asked Questions (FAQ)

Q: Can the RMC27MWST directly replace the AMC27MWST in existing assemblies?

A: The RMC27MWST shares the same manufacturer (Sullins Connector Solutions) and related base product number (RMC27 vs. AMC27), indicating design family compatibility. Both parts are 54-position, 2-row card edge connectors at 0.100" pitch. Mechanical and electrical interface compatibility is maintained through the same connector category and pitch specification.

Q: What is the primary difference between these two parts?

A: The AMC27MWST is classified as obsolete, while the RMC27MWST maintains active product status. The substitute part offers ongoing manufacturing support, improved supply chain availability (1082 pieces in stock vs. 660 pieces), and current export classification (EAR99 vs. OBSOLETE).

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The RMC27MWST carries EAR99 export classification, which provides standard export treatment. The AMC27MWST carries an obsolete classification that may restrict future procurement and distribution.

Q: What parameters must match for substitution in card edge connector applications?

A: Critical matching parameters include number of positions (54), number of rows (2), pitch (0.100"/2.54mm), gender (male), and manufacturer (Sullins Connector Solutions). These parameters define the electrical interface and physical form factor required for edgecard compatibility.

Q: Is the RMC27MWST suitable for the same operating temperature range?

A: The AMC27MWST specifies an operating temperature range of -65°C to 200°C. The RMC27MWST technical specifications for operating temperature were not provided in the available data. Verification of thermal performance requirements against application specifications is necessary for temperature-critical applications.

Q: What is the significance of the MSL rating for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. These connectors can be stored and handled under standard conditions without special moisture control measures, simplifying inventory management and field service logistics.
