Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC38MSST is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer ensures design compatibility)
• Number of Positions: 76 positions (electrical interface requirement)
• Number of Rows: 2 rows (physical configuration requirement)
• Pitch: 0.100" (2.54mm) (mechanical spacing requirement)
• Contact Material: Beryllium Copper (electrical performance and durability)
• Contact Finish: Gold (corrosion resistance and signal integrity)
• Insulation Material: Polyphenylene Sulfide (PPS) (thermal and chemical stability)
• Operating Temperature Range: -65°C ~ 200°C (environmental specification)
• Compliance: ROHS3 Compliant, REACH Unaffected (regulatory requirement)

The RMC38MSST is identified as a direct substitute based on matching the core electrical and mechanical parameters required for card edge connector applications at 0.100" pitch with 76-position, 2-row configuration from the same manufacturer.
