AMC47MMST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC47MMST is a 94-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, gold-plated beryllium copper contacts, and operates across the temperature range of -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility while ensuring continued supply availability and compliance with current regulatory standards.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC47MMST with the active RMC47MMST is based on equivalence across all critical electrical and mechanical parameters that define functional compatibility in card edge connector applications. Both connectors maintain identical specifications for the following parameters: 94-position configuration, 0.100" (2.54mm) pitch, male gender, dual read-out, 2-row arrangement, gold contact finish at 30.0µin thickness, -65°C to 200°C operating temperature range, solder termination, PPS insulation material, flush mount with threaded insert (4-40), ROHS3 compliance, and MSL 1 rating.

The RMC47MMST differs from the AMC47MMST in the following non-critical parameters: contact material (phosphor bronze versus beryllium copper), product status (active versus obsolete), color designation (black), card thickness specification (0.062" specified), and mounting type classification (through hole). These differences do not affect electrical or mechanical compatibility with female edgecard interfaces. The substitute part maintains all functional requirements for direct replacement in applications previously utilizing the AMC47MMST.

Parameter Comparison

Engineering Selection Recommendations

The RMC47MMST is the direct active equivalent for the obsolete AMC47MMST. Selection of the RMC47MMST is based on the following engineering criteria:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current regulatory requirements. The RMC47MMST carries active product status with assigned ECCN (EAR99) and HTSUS classification, providing supply chain continuity and regulatory clarity.

Functional Equivalence: The RMC47MMST maintains all critical electrical and mechanical parameters required for female edgecard interface compatibility, including 94-position configuration, 0.100" pitch, dual read-out, gold contact finish at specified thickness, and full operating temperature range.

Supply Availability: The RMC47MMST is currently in active production with documented inventory availability, eliminating supply risk associated with the obsolete AMC47MMST.

Certification Alignment: Both parts share identical MSL 1 rating and temperature operating range, ensuring equivalent performance in moisture and thermal environments.

Frequently Asked Questions (FAQ)

Q: Can the RMC47MMST directly replace the AMC47MMST in existing applications?

A: Yes. The RMC47MMST maintains functional equivalence across all critical parameters: 94-position configuration, 0.100" pitch, male gender, dual read-out, gold contact finish, operating temperature range, solder termination, and PPS insulation. The connector interfaces identically with female edgecards.

Q: What is the difference in contact material between these connectors?

A: The AMC47MMST uses beryllium copper contacts, while the RMC47MMST uses phosphor bronze contacts. Both materials are gold-plated at 30.0µin thickness and provide equivalent electrical performance for card edge connector applications.

Q: Are there any compatibility issues with the card thickness specification?

A: The RMC47MMST specifies 0.062" (1.57mm) card thickness. This specification defines the mechanical interface with female edgecards. Compatibility depends on the actual card thickness in the application. The AMC47MMST does not specify card thickness in the provided data.

Q: Do both connectors meet current regulatory requirements?

A: Yes. Both the AMC47MMST and RMC47MMST are ROHS3 compliant and REACH unaffected. The RMC47MMST carries active ECCN (EAR99) classification, confirming current regulatory status.

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

A: Both connectors carry MSL 1 rating, indicating unlimited moisture sensitivity level with no special storage or handling requirements.

Q: Are the flange and mounting features identical?

A: Yes. Both connectors feature flush mount configuration with top opening and threaded insert (4-40), providing identical mechanical mounting characteristics.
