AMC57MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC57MMSD is a 114-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 AMC57MMSD 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 AMC57MMSD is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 114 total (57 per row, 2 rows)
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Card type: Fits female edgecards
• Read out configuration: Dual
• Termination method: Solder
• Operating temperature range: -65°C to 200°C
• Contact finish: Gold, 30.0µin (0.76µm)
• Insulation material: Polyphenylene Sulfide (PPS)
• Compliance: ROHS3 compliant, REACH unaffected

Allowable Variations:

• Contact material (beryllium copper to phosphor bronze)
• Flange opening orientation (side opening to top opening)
• Connector color (natural to black)
• Mounting type classification
• Product status (obsolete to active)

The RMC57MMSD meets all mandatory matching parameters while introducing allowable variations in contact material, flange configuration, and product status.

Parameter Comparison

Engineering Selection Recommendations

The RMC57MMSD serves as a direct functional substitute for the obsolete AMC57MMSD. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 114-position configuration, 0.100" pitch, dual read-out, solder termination, and -65°C to 200°C operating range.

The RMC57MMSD holds active product status, ensuring availability and ongoing manufacturer support. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current applications.

The contact material difference (beryllium copper versus phosphor bronze) and flange opening orientation (side opening versus top opening) represent allowable design variations that do not compromise functional compatibility with female edgecard interfaces. The specified card thickness of 0.062" (1.57mm) for the RMC57MMSD provides dimensional clarity for the substitute component.

Selection of the RMC57MMSD eliminates obsolescence risk while preserving full electrical and mechanical compatibility with existing female edgecard designs.

Frequently Asked Questions (FAQ)

Q: Can the RMC57MMSD directly replace the AMC57MMSD in existing applications?

A: Yes. Both connectors share identical position count (114), pitch (0.100"), gender (male), read-out configuration (dual), termination method (solder), operating temperature range (-65°C to 200°C), and contact finish specifications (gold, 30.0µin). The RMC57MMSD is functionally equivalent for interfacing with female edgecards.

Q: What is the significance of the contact material difference between beryllium copper and phosphor bronze?

A: Both materials are established contact materials for card edge connectors. The contact material difference does not affect the electrical or mechanical compatibility with female edgecard interfaces. Both materials support the specified gold finish and operating temperature range.

Q: Does the flange opening orientation difference affect compatibility?

A: No. The flange opening orientation (side opening on AMC57MMSD versus top opening on RMC57MMSD) is a design variation that does not impact the connector's ability to interface with female edgecards or its electrical performance.

Q: Are both connectors compliant with current regulatory standards?

A: Yes. Both the AMC57MMSD and RMC57MMSD are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements.

Q: What is the significance of the RMC57MMSD's active product status?

A: Active product status indicates that the RMC57MMSD is currently manufactured and supported by Sullins Connector Solutions. This ensures component availability and eliminates obsolescence concerns associated with the AMC57MMSD.

Q: Is the specified card thickness of 0.062" (1.57mm) for the RMC57MMSD a limiting factor?

A: The card thickness specification for the RMC57MMSD indicates the design parameter for female edgecard compatibility. This specification does not restrict substitution; it clarifies the mechanical interface requirement.

Q: Do both connectors support the same solder termination process?

A: Yes. Both connectors utilize solder termination, ensuring compatibility with standard PCB assembly and rework procedures.
