Substitute Part Grouping Explanation

Substitution of the AMC28MWST is determined by the following critical parameters that must align between the main part and substitute candidates:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer ensures design compatibility)
• Category: Card Edge Connectors (functional category match)
• Number of Positions: 56 (electrical interface requirement)
• Number of Rows: 2 (physical configuration requirement)
• Pitch: 0.100" (2.54mm) (mechanical spacing requirement)
• Gender: Male (connector orientation requirement)

Secondary Compliance Criteria:

• RoHS3 Compliance (regulatory requirement)
• Moisture Sensitivity Level 1 (handling and storage compatibility)
• REACH Unaffected status (regulatory requirement)

The substitute part RMC28MWST is identified as a direct equivalent based on manufacturer continuity and base product number alignment (RMC28 vs. AMC28 series designation). The RMC28MWST maintains the same core electrical and mechanical specifications while offering active product status and current procurement availability.

Engineering Selection Recommendations

The RMC28MWST is the direct substitute for the obsolete AMC28MWST. Selection of the RMC28MWST is supported by the following engineering factors:

Product Status Alignment: The RMC28MWST maintains active product status with Sullins Connector Solutions, ensuring continued availability for procurement, technical support, and field service requirements. The AMC28MWST obsolete classification creates supply chain risk for new production and maintenance applications.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement. Moisture sensitivity level equivalence (MSL 1) ensures identical handling, storage, and packaging protocols.

Manufacturer Continuity: Both connectors are manufactured by Sullins Connector Solutions, providing design continuity and eliminating cross-manufacturer compatibility variables. The RMC28 base product number represents the active series continuation of the AMC28 series.

Export Classification: The RMC28MWST carries EAR99 export classification, providing broader international procurement flexibility compared to the obsolete classification of the main part.

Frequently Asked Questions (FAQ)

Q: What are the primary electrical differences between the AMC28MWST and RMC28MWST?

A: Based on provided specifications, both connectors are 56-position, 2-row card edge connectors manufactured by Sullins Connector Solutions at 0.100" (2.54mm) pitch. The RMC28MWST is the active product line continuation and maintains electrical interface compatibility with the obsolete AMC28MWST.

Q: Can the RMC28MWST be used as a direct replacement in existing designs?

A: The RMC28MWST is classified as a direct substitute for the AMC28MWST. Both parts share the same manufacturer, connector category, position count, row configuration, and pitch specification. Substitution is supported by regulatory compliance alignment and identical moisture sensitivity classification.

Q: What is the significance of the base product number change from AMC28 to RMC28?

A: The base product number change from AMC28 to RMC28 indicates a product line evolution within the Sullins Connector Solutions portfolio. The RMC28 series represents the active continuation of the AMC28 series, with the RMC28MWST maintaining the same core specifications while offering current production status and procurement availability.

Q: Are there any compliance or certification differences between these parts?

A: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 classification. The RMC28MWST carries EAR99 export classification, providing standard export treatment. These compliance alignments ensure equivalent regulatory acceptance in procurement and design applications.

Q: What should be considered when transitioning from AMC28MWST to RMC28MWST in production?

A: Transition from the obsolete AMC28MWST to the active RMC28MWST requires verification of mechanical fit within the target application, including flange feature compatibility and mounting configuration. Both parts share identical pitch and position specifications, supporting direct mechanical substitution. Procurement should reference the RMC28MWST part number for all new orders and field service applications.
