AMC43MWST Equivalent & Substitute Parts

Part Overview

The AMC43MWST is an 86-position male card edge connector manufactured by Sullins Connector Solutions. This connector is designed to interface with female edgecards using a 0.100" (2.54mm) pitch configuration with dual read-out capability. The part features beryllium copper contacts with gold plating and operates across a temperature range of -65°C to 200°C. The AMC43MWST is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure ongoing component availability for production and field service applications.

Substitute Part Grouping Explanation

Substitution of the AMC43MWST is based on alignment of critical electrical and mechanical parameters that define functional compatibility within card edge connector applications. The primary substitution candidate is the RMC43MWST, manufactured by Sullins Connector Solutions under the same base product family (RMC43 versus AMC43).

The substitution logic is established through the following key parameters:

Electrical Compatibility:

• Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment
• Both parts share MSL rating of 1 (Unlimited), indicating identical moisture sensitivity classification

Mechanical Compatibility:

• Both parts are manufactured by Sullins Connector Solutions, ensuring design lineage and connector family consistency
• Both parts are classified as card edge connectors, confirming functional category alignment
• The RMC43MWST is designated as active product status, providing ongoing availability and manufacturing support

Availability Status:

• The AMC43MWST is obsolete with 1059 pieces in current inventory
• The RMC43MWST is active with 921 pieces in current inventory, ensuring long-term supply chain viability

Engineering Selection Recommendations

Primary Recommendation: RMC43MWST

The RMC43MWST is the direct substitute for the obsolete AMC43MWST. Both components are manufactured by Sullins Connector Solutions and share identical regulatory compliance classifications (ROHS3 Compliant, REACH Unaffected) and moisture sensitivity ratings (MSL 1 - Unlimited).

The RMC43MWST holds active product status, ensuring continued manufacturing support, availability, and technical documentation. This status transition from obsolete to active provides design security for new production builds and field service replacements.

Both parts maintain equivalent environmental and regulatory standing, supporting seamless integration into existing designs without compliance re-qualification. The ECCN classification change from OBSOLETE to EAR99 reflects the active status of the substitute part and does not introduce additional export control restrictions.

Selection of the RMC43MWST eliminates obsolescence risk while maintaining connector family consistency within the Sullins product portfolio.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC43MWST?

A: The AMC43MWST is classified as obsolete. The RMC43MWST provides an active, in-stock alternative from the same manufacturer, ensuring continued availability and manufacturing support.

Q: Are the AMC43MWST and RMC43MWST electrically equivalent?
