AMC45MSST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC45MSST is a 90-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards at 0.100" (2.54mm) pitch. This connector features dual read-out configuration with beryllium copper contacts finished in gold and operates across a temperature range of -65°C to 200°C. The part is classified as obsolete, necessitating identification of active substitute components to maintain design continuity and ensure procurement availability for new production and field service applications.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC45MSST is based on alignment of critical electrical and mechanical parameters within the card edge connector category. The primary substitute identified is the RMC45MSST, also manufactured by Sullins Connector Solutions. Substitution logic is determined by the following parameters:

Critical Substitution Parameters:

• Manufacturer consistency (Sullins Connector Solutions)
• Connector category (Card Edge Connectors)
• Base product number alignment (AMC45 to RMC45 series)
• Regulatory compliance (ROHS3 Compliant, REACH Unaffected, MSL 1)
• Connector configuration (2-row, 90-position architecture)

The RMC45MSST maintains the same base product family designation and regulatory certifications, establishing functional equivalence within the Sullins card edge connector portfolio. The substitute part transitions from obsolete to active product status, ensuring continued availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The RMC45MSST is the designated substitute for the obsolete AMC45MSST based on the following engineering criteria:

Product Status Transition: The AMC45MSST is classified as obsolete, creating supply chain risk for ongoing production and field service requirements. The RMC45MSST maintains active product status with Sullins Connector Solutions, ensuring continued manufacturing support, quality assurance, and procurement availability.

Regulatory Compliance Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and hazardous substance restrictions applicable to electronic component procurement. Moisture sensitivity level remains constant at MSL 1 (unlimited), indicating no special handling requirements during storage or assembly.

Export Classification: The RMC45MSST carries EAR99 classification, establishing standard export control treatment. This classification supports global supply chain operations without specialized licensing requirements.

Manufacturer Continuity: Both parts originate from Sullins Connector Solutions, maintaining design consistency, quality standards, and technical support within a single manufacturer ecosystem. The transition from AMC45 to RMC45 base product series reflects product line evolution while preserving functional compatibility within the 90-position, 2-row card edge connector architecture.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC45MSST?

A: The AMC45MSST is classified as obsolete, creating procurement challenges. The RMC45MSST provides an active alternative from the same manufacturer, ensuring continued availability and manufacturing support.

Q: Are the AMC45MSST and RMC45MSST electrically equivalent?

A: Both components are 90-position, 2-row card edge connectors manufactured by Sullins Connector Solutions. They share identical regulatory compliance certifications (ROHS3, REACH unaffected, MSL 1) and maintain the same base product family designation, establishing functional equivalence within the card edge connector category.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on manufacturer consistency, connector category alignment, base product number series, regulatory compliance certifications, and connector configuration (position count and row arrangement). These parameters ensure mechanical and electrical compatibility within the application environment.

Q: Does the RMC45MSST require different handling or storage procedures?

A: No. Both components maintain identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special storage or handling requirements. Standard electronic component storage practices apply to both parts.

Q: Are there any export or trade restrictions affecting the RMC45MSST?

A: The RMC45MSST carries EAR99 export classification, which is the standard category for most commercial electronic components. This classification does not impose specialized licensing requirements for standard commercial distribution channels.

Q: Can the RMC45MSST be used as a direct replacement in existing designs?

A: The RMC45MSST is functionally equivalent to the AMC45MSST within the card edge connector category. Design validation should confirm mechanical fit, electrical performance, and thermal characteristics within the specific application environment.
