Substitute Part Grouping Explanation

Substitution of the AMC21MSST 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)
• Number of Positions: 42 (electrical interface requirement)
• Number of Rows: 2 (physical configuration requirement)
• Pitch: 0.100" (2.54mm) (mechanical interface requirement)
• Gender: Male (connector orientation requirement)
• Read Out: Dual (signal access configuration)

Compliance & Environmental Criteria:

• RoHS Status: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage requirement)
• REACH Status: REACH Unaffected (regulatory requirement)

The RMC21MSST is identified as a direct substitute based on manufacturer continuity and base product number alignment (RMC21 vs. AMC21 series). The substitute part maintains active product status, ensuring ongoing availability and support.
