AMC55MWST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC55MWST is a 110-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 equivalent alternatives to maintain design continuity and ensure procurement availability for new production and field service applications.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC55MWST is determined by alignment of critical electrical and mechanical parameters within the card edge connector category. The primary substitution candidate, RMC55MWST, shares the same base product number designation (AMC55 vs. RMC55 series) and maintains compatibility through identical connector architecture for 110-position, 2-row, 0.100" pitch applications.

The substitution logic is based on the following key parameters:

• Number of Positions and Row Configuration: Both connectors support 110 positions in a 2-row arrangement, ensuring pin-to-pin compatibility with existing female edgecard interfaces.
• Pitch Specification: The 0.100" (2.54mm) pitch is maintained, guaranteeing mechanical fit with legacy and current edgecard designs.
• Connector Type and Gender: Male connector configuration for female edgecard mating remains consistent.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.
• Moisture Sensitivity: MSL 1 (Unlimited) classification is preserved, indicating no special moisture handling requirements.
• Product Status Transition: The RMC55MWST is classified as active, providing ongoing availability and manufacturing support.

Engineering Selection Recommendations

The RMC55MWST is the primary substitute for the obsolete AMC55MWST based on the following engineering criteria:

Product Status and Availability: The RMC55MWST maintains active product status with Sullins Connector Solutions, ensuring continued manufacturing support, procurement availability, and technical documentation access. The AMC55MWST obsolete classification restricts future sourcing and support options.

Regulatory Compliance Alignment: Both connectors maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental regulations and eliminating compliance-related redesign requirements.

Moisture Sensitivity Classification: The MSL 1 (Unlimited) rating is consistent across both parts, indicating no additional moisture control measures are required during storage, handling, or assembly.

Connector Architecture: The RMC55MWST is designated as a 2-row, 110-position through-hole card edge connector, maintaining the core electrical and mechanical interface specifications required for female edgecard compatibility.

Selection of the RMC55MWST for new designs and production applications eliminates obsolescence risk while preserving functional compatibility with existing edgecard interfaces.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC55MWST?

A: The AMC55MWST is classified as obsolete, which restricts procurement availability and manufacturer support. The RMC55MWST is an active product offering equivalent functionality with ongoing manufacturing and supply chain support.

Q: Are the AMC55MWST and RMC55MWST mechanically compatible with the same female edgecards?

A: Both connectors are 110-position, 2-row male card edge connectors with 0.100" (2.54mm) pitch specifications. The mechanical interface with female edgecards is maintained across both part numbers.

Q: Do both connectors meet current environmental and regulatory requirements?

A: Yes. Both the AMC55MWST and RMC55MWST are ROHS3 compliant and REACH unaffected, satisfying current environmental regulations without requiring design modifications.

Q: What is the moisture sensitivity level for both connectors?

A: Both connectors are classified as MSL 1 (Unlimited), indicating no special moisture control or baking procedures are required prior to assembly or deployment.

Q: Can the RMC55MWST be used as a direct replacement in existing designs?

A: The RMC55MWST is designed as a functional equivalent for the AMC55MWST within the card edge connector category. Verification of specific electrical and mechanical requirements against the detailed connector specifications is necessary for each application.

Q: What is the difference between the AMC55 and RMC55 base product series?

A: The AMC55 series represents the obsolete product line, while the RMC55 series represents the active equivalent offering from Sullins Connector Solutions. Both series maintain compatibility with 110-position, 2-row, 0.100" pitch edgecard interfaces.
