AMC41MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC41MMSD is an 82-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 -65°C to 200°C. The AMC41MMSD is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for production and field service applications.

Engineering Selection Recommendations

The RMC41MMSD serves as the active equivalent to the obsolete AMC41MMSD. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 82-position configuration, 0.100" pitch, dual read-out, solder termination, gold contact finish, and operating temperature range of -65°C to 200°C.

Both parts are ROHS3 compliant and carry MSL 1 ratings, ensuring regulatory alignment and moisture handling compatibility. The RMC41MMSD is currently in active production status with 836 units in stock, providing assured long-term availability compared to the obsolete AMC41MMSD.

Physical differences exist in contact material composition (phosphor bronze versus beryllium copper), flange opening orientation (top versus side), and specified card thickness (0.062" for RMC41MMSD). These differences do not affect functional compatibility with female edgecard interfaces when the RMC41MMSD is applied to applications originally designed for the AMC41MMSD, provided the 0.062" card thickness specification is accommodated in the receiving edgecard design.

Frequently Asked Questions (FAQ)

Q: Can the RMC41MMSD directly replace the AMC41MMSD in existing designs?

A: The RMC41MMSD is functionally equivalent for applications requiring 82-position, 0.100" pitch male card edge connectors with dual read-out and solder termination. The connector maintains identical electrical performance and temperature operating range. Physical layout compatibility depends on accommodation of the top-opening flange orientation and 0.062" card thickness specification in the receiving edgecard assembly.

Q: What is the difference between beryllium copper and phosphor bronze contact materials?

A: Both materials are provided in the input specifications. Beryllium copper is used in the AMC41MMSD; phosphor bronze is used in the RMC41MMSD. Both materials are suitable for gold-plated contact applications at the specified 30.0µin finish thickness and operate across the -65°C to 200°C temperature range.

Q: Does the flange opening orientation change affect connector installation?

A: The AMC41MMSD features side opening; the RMC41MMSD features top opening. This difference affects the physical approach angle during insertion and removal. Design layouts must accommodate the top-opening configuration of the RMC41MMSD.

Q: Are both connectors RoHS compliant?

A: Yes. Both the AMC41MMSD and RMC41MMSD are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, meeting current regulatory requirements for electronic component procurement.

Q: What card thickness does the RMC41MMSD accommodate?

A: The RMC41MMSD is specified for 0.062" (1.57mm) card thickness. The AMC41MMSD does not specify a card thickness parameter. Edgecard designs must be verified to accommodate this thickness specification.

Q: Is the RMC41MMSD available in inventory?

A: Yes. The RMC41MMSD is in active production status with 836 units currently in stock, ensuring availability for new production and field service applications.
