Substitute Part Grouping Explanation

Substitution of the AMC51MWST 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: 102 (electrical interface requirement)
• Number of Rows: 2 (physical configuration requirement)
• Pitch: 0.100" (2.54mm) (mechanical spacing requirement)
• Gender: Male (connector orientation requirement)
• RoHS Status: ROHS3 Compliant (regulatory compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental handling requirement)

The RMC51MWST qualifies as a direct substitute based on shared manufacturer origin and base product number (RMC51 vs. AMC51), indicating design lineage within the same connector family. The substitute part maintains active product status, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The RMC51MWST is the appropriate substitute for the obsolete AMC51MWST based on the following engineering factors:

Product Status: The RMC51MWST maintains active product status with confirmed inventory availability (1166 pieces), whereas the AMC51MWST is obsolete with no ongoing manufacturing support.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) classification, ensuring compatibility with current environmental and handling standards.

Manufacturer Continuity: Both connectors originate from Sullins Connector Solutions, with related base product numbers (RMC51 and AMC51) indicating design family relationship and manufacturing process alignment.

Availability: The substitute part demonstrates superior supply chain status with active production and higher inventory levels, supporting both new production requirements and field service needs.

Selection of the RMC51MWST eliminates obsolescence risk while maintaining compliance with applicable regulatory frameworks and environmental handling requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC51MWST?
