AMC56MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC56MMSD is a 112-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 gold-plated beryllium copper contacts and operates across the temperature range of -65°C to 200°C.

The AMC56MMSD is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and replacement requirements for legacy systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC56MMSD is evaluated based on the following critical parameters that determine functional and mechanical compatibility:

Core Compatibility Parameters:

• Number of positions (112 total, 56 per row, 2 rows)
• Pitch specification (0.100" / 2.54mm)
• Connector gender (Male)
• Read out configuration (Dual)
• Termination method (Solder)
• Operating temperature range (-65°C to 200°C)
• Contact finish specification (Gold, 30.0µin)
• Insulation material (Polyphenylene Sulfide)
• Compliance certifications (ROHS3, REACH Unaffected)

The RMC56MMSD qualifies as a direct substitute based on alignment across all core compatibility parameters. Variations in contact material (phosphor bronze versus beryllium copper), card thickness specification, flange opening orientation, and color do not prevent functional substitution when the primary electrical and mechanical requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The RMC56MMSD is an active product offering from Sullins Connector Solutions and serves as the direct substitute for the obsolete AMC56MMSD. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 112-position configuration, 0.100" pitch, dual read-out, solder termination, gold contact finish at 30.0µin thickness, and -65°C to 200°C operating temperature range.

Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The RMC56MMSD is currently in active production with inventory availability, whereas the AMC56MMSD is obsolete.

Differences in contact material (phosphor bronze in RMC56MMSD versus beryllium copper in AMC56MMSD), flange opening orientation (top opening versus side opening), and specified card thickness (0.062" for RMC56MMSD) do not affect functional compatibility for standard card edge connector applications. The RMC56MMSD is suitable for direct replacement in applications previously utilizing the AMC56MMSD.

Frequently Asked Questions (FAQ)

Q: Can the RMC56MMSD directly replace the AMC56MMSD in existing applications?

A: Yes. Both connectors share identical specifications for position count (112), pitch (0.100"), gender (male), read-out configuration (dual), termination method (solder), contact finish (gold at 30.0µin), operating temperature range (-65°C to 200°C), and insulation material (PPS). The RMC56MMSD is the active equivalent for the obsolete AMC56MMSD.

Q: What is the difference between the flange features of these two connectors?

A: The AMC56MMSD features a side opening flange, while the RMC56MMSD features a top opening flange. Both are flush mount with unthreaded 0.125" (3.18mm) diameter specifications. The opening orientation difference does not affect electrical performance but may impact physical board layout and assembly procedures.

Q: Why does the RMC56MMSD specify a card thickness of 0.062" while the AMC56MMSD does not?

A: The RMC56MMSD includes a documented card thickness specification of 0.062" (1.57mm) as part of its active product documentation. This specification defines the edgecard thickness with which the connector is designed to interface. The AMC56MMSD documentation does not include this parameter, though it is designed for the same standard edgecard thickness.

Q: Are there differences in contact material between these connectors?

A: Yes. The AMC56MMSD uses beryllium copper contacts, while the RMC56MMSD uses phosphor bronze contacts. Both materials are plated with gold at 30.0µin thickness. Both contact materials are suitable for card edge connector applications and maintain the same electrical performance characteristics at the specified operating temperature range.

Q: Do both connectors meet current compliance requirements?

A: Yes. Both the AMC56MMSD and RMC56MMSD are ROHS3 compliant and REACH unaffected. The RMC56MMSD carries an ECCN classification of EAR99 and HTSUS code 8536.69.4040.

Q: What is the current availability status of these connectors?

A: The AMC56MMSD is obsolete. The RMC56MMSD is an active product with current inventory availability from Sullins Connector Solutions.
