AMC45MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC45MMSD is a 90-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 AMC45MMSD 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC45MMSD is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 90
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Number of Rows: 2
• Termination: Solder
• Contact Finish: Gold
• Operating Temperature Range: -65°C ~ 200°C
• Material - Insulation: Polyphenylene Sulfide (PPS)
• RoHS Status: ROHS3 Compliant

The RMC45MMSD meets all mandatory matching parameters and qualifies as a direct substitute. This part maintains functional and electrical compatibility while offering active product status and improved availability. Variations in contact material (phosphor bronze versus beryllium copper), flange opening configuration (top opening versus side opening), and color designation do not preclude substitution when all critical electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The RMC45MMSD is the direct substitute for the obsolete AMC45MMSD. Both parts are manufactured by Sullins Connector Solutions and maintain identical electrical and mechanical specifications across all critical parameters. The RMC45MMSD carries active product status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The RMC45MMSD is currently in stock with 803 pieces available, providing immediate procurement capability.

Selection of the RMC45MMSD eliminates obsolescence risk while maintaining full functional compatibility with existing designs specified for the AMC45MMSD.

Frequently Asked Questions (FAQ)

Q: Can the RMC45MMSD directly replace the AMC45MMSD in existing designs?

A: Yes. The RMC45MMSD maintains identical electrical and mechanical specifications across all critical parameters including position count, pitch, termination method, contact finish, operating temperature range, and insulation material. Direct substitution is supported.

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

A: The AMC45MMSD uses beryllium copper contacts, while the RMC45MMSD uses phosphor bronze contacts. Both materials are plated with gold to 30.0µin thickness and provide equivalent electrical performance for card edge connector applications.

Q: Are there differences in the flange configuration between these parts?

A: The AMC45MMSD features a side opening flange, while the RMC45MMSD features a top opening flange. Both are flush mount, unthreaded, 0.125" (3.18mm) diameter configurations. Flange opening orientation does not affect electrical compatibility.

Q: What is the card thickness specification for the RMC45MMSD?

A: The RMC45MMSD is specified for 0.062" (1.57mm) card thickness. This specification is provided for the substitute part and should be verified against the target edgecard thickness in the application.

Q: Are both parts RoHS compliant?

A: Yes. Both the AMC45MMSD and RMC45MMSD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: Why is the AMC45MMSD classified as obsolete?

A: The AMC45MMSD is listed as obsolete by the manufacturer. The RMC45MMSD is the active equivalent part and is the recommended selection for new designs and ongoing production requirements.
