AMC54MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC54MMSD is a 108-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 -65°C to 200°C. The AMC54MMSD is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC54MMSD is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 108
• Gender: Male
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Read Out: Dual
• Termination: Solder
• Operating Temperature Range: -65°C ~ 200°C
• Contact Finish: Gold
• Contact Finish Thickness: 30.0µin (0.76µm)
• Insulation Material: Polyphenylene Sulfide (PPS)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The RMC54MMSD meets all mandatory matching parameters and qualifies as a direct substitute. Differences in contact material (phosphor bronze versus beryllium copper), flange opening orientation (top opening versus side opening), card thickness specification, color designation, and mounting type classification do not preclude substitution when the core electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The RMC54MMSD is the active equivalent substitute for the obsolete AMC54MMSD. Both components are manufactured by Sullins Connector Solutions and maintain identical electrical and mechanical interface specifications across all critical parameters including position count, pitch, row configuration, read-out type, contact finish specification, operating temperature range, and regulatory compliance status.

The RMC54MMSD carries active product status, ensuring continued availability and manufacturing support. Both components satisfy ROHS3 compliance requirements and maintain unlimited moisture sensitivity classification. The substitute part is suitable for direct replacement in applications requiring 108-position male card edge connectors with 0.100" pitch and dual read-out configuration.

Frequently Asked Questions (FAQ)

Q: Can the RMC54MMSD directly replace the AMC54MMSD in existing designs?

A: Yes. The RMC54MMSD maintains identical electrical and mechanical interface specifications across all critical parameters including position count, pitch, row configuration, read-out type, contact finish thickness, operating temperature range, and regulatory compliance status.

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

A: Both contact materials are suitable for gold-plated card edge connector applications. The contact material difference does not affect the electrical interface or mechanical compatibility when both materials are finished with identical gold plating thickness of 30.0µin (0.76µm).

Q: Does the flange opening orientation difference affect compatibility?

A: The flange opening orientation difference (side opening versus top opening) relates to physical mounting configuration and does not affect electrical interface compatibility with female edgecards. Physical mounting considerations must be evaluated based on specific application requirements.

Q: Are both components RoHS compliant?

A: Yes. Both the AMC54MMSD and RMC54MMSD are ROHS3 compliant and carry unlimited moisture sensitivity classification (MSL 1).

Q: What is the inventory status for the substitute part?

A: The RMC54MMSD is actively manufactured and maintained in inventory with 715 pieces of new original stock available.

Q: Is the card thickness specification critical for substitution?

A: The RMC54MMSD specifies 0.062" (1.57mm) card thickness. The original AMC54MMSD does not specify card thickness in the provided parameters. Physical compatibility with existing edgecards must be confirmed based on actual card dimensions in the application.
