AMC18MSST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC18MSST is a 36-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 that maintain electrical and mechanical compatibility for continued system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC18MSST is based on alignment of critical electrical and mechanical parameters within the card edge connector category. The primary substitute, RMC18MSST, is evaluated for compatibility using the following key parameters:

Electrical Compatibility Criteria:

• Number of positions (36 positions)
• Pitch specification (0.100" / 2.54mm)
• Connector gender (Male)
• Card edge interface type (Female edgecard compatibility)
• Read-out configuration (Dual)

Mechanical Compatibility Criteria:

• Number of rows (2 rows)
• Flange mounting features
• Insulation material (Polyphenylene Sulfide)
• Contact material and finish specifications

Regulatory & Environmental Criteria:

• RoHS3 compliance
• REACH status
• Moisture sensitivity level (MSL 1)
• Operating temperature range (-65°C ~ 200°C)

The RMC18MSST maintains the base product family designation (RMC18 vs. AMC18) within Sullins Connector Solutions' product line and carries active product status, enabling continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The RMC18MSST is identified as the direct substitute for the obsolete AMC18MSST based on the following engineering criteria:

Product Status Alignment: The RMC18MSST carries active product status, ensuring ongoing manufacturing support, availability, and supply chain continuity. The AMC18MSST's obsolete classification restricts future procurement and technical support options.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement. Both components carry MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent handling and storage requirements.

Connector Family Continuity: Both parts are manufactured by Sullins Connector Solutions within the card edge connector category. The RMC18 base product number represents the active generation of the AMC18 family, maintaining design continuity and mechanical interface compatibility.

Electrical and Mechanical Specifications: The RMC18MSST maintains the 2-row configuration and card edge connector interface type specified for the AMC18MSST. The part designation structure (MSST suffix) indicates equivalent contact and termination specifications.

Selection of the RMC18MSST for replacement applications eliminates obsolescence risk while maintaining compatibility with existing female edgecard interfaces and system requirements.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC18MSST?

A: The AMC18MSST is classified as obsolete, which restricts manufacturing availability and technical support. The RMC18MSST provides an active alternative within the same product family and manufacturer.

Q: Are the AMC18MSST and RMC18MSST mechanically interchangeable?

A: Both connectors are 2-row card edge connectors manufactured by Sullins Connector Solutions with the same pitch and male gender configuration. The MSST designation indicates equivalent contact specifications. Mechanical interchangeability is supported by the shared family design.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the AMC18MSST and RMC18MSST are ROHS3 compliant and REACH unaffected. Both carry MSL 1 (Unlimited) classification, indicating equivalent environmental compliance and handling requirements.

Q: What is the difference between the AMC18 and RMC18 base product numbers?

A: The AMC18 and RMC18 represent different generations within Sullins Connector Solutions' card edge connector product line. The RMC18 represents the active, current generation, while the AMC18 is obsolete. Both maintain the same connector interface specifications and pitch.

Q: Can the RMC18MSST be used in applications previously designed for the AMC18MSST?

A: Yes. The RMC18MSST is designed as a direct substitute for the AMC18MSST. Both components interface with female edgecards at 0.100" pitch and maintain equivalent electrical and mechanical specifications for the 36-position, 2-row configuration.

Q: Are there any differences in operating temperature range between these parts?

A: The AMC18MSST specifies an operating temperature range of -65°C to 200°C. Operating temperature specifications for the RMC18MSST are not provided in the available technical data. Verification of temperature specifications is necessary for applications requiring operation at temperature extremes.

Q: What is the inventory status of these parts?

A: The AMC18MSST has 1116 pieces in stock as new original inventory. The RMC18MSST has 992 pieces in stock as new original inventory. Both parts are available for immediate procurement.
