Substitute Part Grouping Explanation

Substitution of the AMC58MSST is determined by the following critical parameters that must align between the main part and substitute alternatives:

Primary Substitution Criteria:

• Number of Positions: 116
• Number of Rows: 2
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Card Type: Fits Female Edgecards
• Read Out: Dual
• Contact Material: Beryllium Copper
• Contact Finish: Gold
• Operating Temperature Range: -65°C ~ 200°C
• Material - Insulation: Polyphenylene Sulfide (PPS)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RMC58MSST represents an active product alternative from the same manufacturer, Sullins Connector Solutions, within the card edge connector category. This substitute maintains the same base product number series (58) and connector configuration, providing functional equivalence for applications currently utilizing the obsolete AMC58MSST.

Parameter Comparison

Engineering Selection Recommendations

The RMC58MSST is the appropriate substitute for the obsolete AMC58MSST based on the following engineering considerations:

Product Status Alignment: The AMC58MSST is classified as obsolete, creating supply chain risk for new designs and ongoing production requirements. The RMC58MSST maintains active product status with current manufacturing availability, ensuring long-term procurement viability.

Regulatory Compliance: Both the main part and substitute maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for electronic component applications. Moisture sensitivity level remains consistent at MSL 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Manufacturer Continuity: Both connectors are manufactured by Sullins Connector Solutions, ensuring design consistency and quality standards across the substitution. The shared base product number series (58) indicates engineering lineage and functional compatibility within the manufacturer's product architecture.

Connector Configuration: The RMC58MSST is specified as a 2-row, 116-position through-hole card edge connector, maintaining the electrical and mechanical interface requirements of the original AMC58MSST design.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC58MSST?

A: The AMC58MSST is classified as obsolete, indicating discontinued manufacturing and limited inventory availability. The RMC58MSST provides an active alternative from the same manufacturer to ensure continued procurement and design support.

Q: Are the AMC58MSST and RMC58MSST mechanically compatible?

A: Both connectors are 116-position, 2-row card edge connectors with 0.100" (2.54mm) pitch designed to interface with female edgecards. The mechanical compatibility is established through the shared connector configuration and pitch specification.

Q: Do both connectors meet the same regulatory standards?

A: Yes. Both the AMC58MSST and RMC58MSST are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity classification, satisfying equivalent regulatory requirements.

Q: What is the difference between the AMC58 and RMC58 base product numbers?

A: The base product numbers indicate different product lines within Sullins Connector Solutions' card edge connector portfolio. The RMC58 represents the active product line successor, while the AMC58 is the discontinued predecessor.

Q: Can the RMC58MSST be used as a direct replacement in existing designs?

A: The RMC58MSST is specified as a through-hole card edge connector with the same 116-position, 2-row configuration and 0.100" pitch as the AMC58MSST. Design validation should confirm mounting type and flange feature compatibility with the specific application requirements.

Q: What inventory status should be considered for procurement planning?

A: The AMC58MSST has 998 pieces in stock as new original inventory. The RMC58MSST has 1033 pieces in stock as new original inventory. For long-term production requirements, the active status of the RMC58MSST provides superior supply chain continuity compared to the obsolete AMC58MSST.
