AMC32MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC32MMSD is a 64-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 AMC32MMSD 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 obsolete AMC32MMSD with the active RMC32MMSD is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Identical 64-position configuration with 32 positions per row
• Matching 0.100" (2.54mm) pitch spacing
• Dual read-out configuration maintained
• Gold contact finish with identical 30.0µin (0.76µm) thickness
• Equivalent operating temperature range (-65°C ~ 200°C)
• Solder termination method preserved

Mechanical Compatibility:

• Male gender connector for female edgecard interface
• Flush mount flange with 0.125" (3.18mm) diameter
• Polyphenylene Sulfide (PPS) insulation material
• Unthreaded flange design

Compliance Equivalence:

• ROHS3 compliance maintained
• MSL 1 (Unlimited) rating preserved
• REACH Unaffected status consistent

The RMC32MMSD represents the direct active successor to the AMC32MMSD within the Sullins Connector Solutions product line, with the primary differences being product status (active versus obsolete) and minor mechanical variations in flange opening orientation and contact material composition.

Parameter Comparison

Engineering Selection Recommendations

The RMC32MMSD is the appropriate substitute for the obsolete AMC32MMSD based on the following engineering criteria:

Product Status and Availability: The AMC32MMSD is classified as obsolete, which restricts long-term component sourcing and supply chain reliability. The RMC32MMSD maintains active product status with documented inventory availability (1079 pieces), ensuring continuity for new production and field service requirements.

Regulatory Compliance: Both connectors maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements. The RMC32MMSD carries ECCN EAR99 classification with HTSUS code 8536.69.4040, providing clear export and trade compliance documentation.

Electrical and Mechanical Equivalence: The RMC32MMSD preserves all critical electrical parameters including 64-position configuration, 0.100" pitch, dual read-out, gold contact finish at 30.0µin thickness, and identical operating temperature range. Mechanical compatibility is maintained through matching flange design, PPS insulation, and solder termination.

Contact Material Consideration: The RMC32MMSD employs phosphor bronze contacts in place of beryllium copper. Both materials provide equivalent electrical performance and durability within the specified operating parameters and contact finish thickness.

Flange Opening Orientation: The RMC32MMSD features top opening flange configuration compared to the side opening of the AMC32MMSD. This difference does not affect electrical function and represents a design refinement in the active product line.

Frequently Asked Questions (FAQ)

Q: Can the RMC32MMSD directly replace the AMC32MMSD in existing designs?

A: Yes. The RMC32MMSD maintains electrical and mechanical compatibility across all critical parameters including position count, pitch, gender, read-out configuration, contact finish, and operating temperature range. The connector interfaces identically with female edgecards at 0.100" pitch.

Q: What is the significance of the contact material change from beryllium copper to phosphor bronze?

A: Both beryllium copper and phosphor bronze provide equivalent electrical conductivity and mechanical durability for card edge connector applications. The phosphor bronze composition in the RMC32MMSD maintains the specified contact finish thickness (30.0µin gold) and performance characteristics across the operating temperature range.

Q: Does the flange opening orientation difference affect installation or performance?

A: The flange opening orientation (top opening in RMC32MMSD versus side opening in AMC32MMSD) is a mechanical design refinement that does not affect electrical function or female edgecard interface compatibility. Installation procedures remain consistent with standard solder termination practices.

Q: Are there any compliance or certification differences between the two connectors?

A: Both connectors maintain ROHS3 compliance and REACH Unaffected status. The RMC32MMSD provides additional trade documentation through ECCN EAR99 classification and HTSUS code 8536.69.4040, supporting clear regulatory and export compliance.

Q: What is the moisture sensitivity level for the RMC32MMSD?

A: The RMC32MMSD carries MSL 1 (Unlimited) rating, identical to the AMC32MMSD. This classification indicates no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Is the RMC32MMSD available in the same packaging as the AMC32MMSD?

A: Packaging specifications are not provided in the technical documentation for either connector. Contact the component supplier for specific packaging and quantity information to match existing procurement requirements.

Q: What is the through-hole mounting type specification for the RMC32MMSD?

A: The RMC32MMSD is specified for through-hole mounting, which is the standard installation method for solder-terminated card edge connectors. This mounting type is compatible with standard PCB assembly processes.
