Substitute Part Grouping Explanation

Substitution of the obsolete AMC44MSST is based on alignment of critical electrical and mechanical parameters within the card edge connector category. The primary substitute identified is the RMC44MSST, also manufactured by Sullins Connector Solutions. This substitute maintains the same base product family designation (44-position per row configuration) and shares compliance certifications with the original part.

The substitution logic is determined by the following parameters:

• Connector Category: Both parts are card edge connectors
• Position Configuration: Both support 88-position, 2-row architecture
• Pitch Specification: Both utilize 0.100" (2.54mm) pitch
• Manufacturer Consistency: Both are Sullins Connector Solutions products
• Compliance Standards: Both are ROHS3 compliant with MSL 1 rating
• Product Status: The substitute is active, ensuring ongoing availability

Parameter Comparison

Engineering Selection Recommendations

The RMC44MSST is the direct substitute for the obsolete AMC44MSST. Both parts share identical compliance certifications (ROHS3, MSL 1, REACH Unaffected) and are manufactured by the same supplier within the same connector family. The RMC44MSST maintains active product status, ensuring availability for procurement and ongoing supply chain support.

Selection of the RMC44MSST eliminates obsolescence risk while preserving regulatory compliance requirements. The active status of the substitute part provides long-term design security and manufacturing continuity.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC44MSST?
