AMC58MMST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC58MMST is a 116-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards using a 0.100" (2.54mm) pitch. This connector features dual read-out configuration, gold-plated beryllium copper contacts, and operates across a temperature range of -65°C to 200°C. The part is classified as obsolete, necessitating identification of active substitute components that maintain functional and electrical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC58MMST with the active RMC58MMST is based on strict alignment of the following critical parameters:

Electrical and Mechanical Compatibility:

• Identical number of positions (116) and row configuration (2 rows)
• Matching pitch specification (0.100" / 2.54mm)
• Identical gender (Male) and card type interface (Fits Female Edgecards)
• Matching dual read-out configuration
• Identical contact finish specification (Gold, 30.0µin thickness)
• Identical operating temperature range (-65°C ~ 200°C)
• Matching termination method (Solder)
• Identical insulation material (Polyphenylene Sulfide)
• Identical flange features (Flush Mount, Top Opening, Threaded Insert, 4-40)

Compliance and Regulatory:

• Both parts maintain ROHS3 compliance
• Both parts have MSL rating of 1 (Unlimited)
• Both parts are REACH Unaffected

Differences Noted: The RMC58MMST introduces a specified card thickness of 0.062" (1.57mm) and includes Through Hole mounting type designation, with phosphor bronze contact material replacing beryllium copper, and black color specification. These differences do not preclude functional substitution within the defined electrical and mechanical parameters.

Engineering Selection Recommendations

The RMC58MMST serves as the direct functional substitute for the obsolete AMC58MMST. Selection of the RMC58MMST is supported by the following engineering criteria:

Product Status and Availability: The RMC58MMST maintains active product status with current inventory availability (736 pcs), whereas the AMC58MMST is classified as obsolete. For new designs and ongoing production requirements, the RMC58MMST provides continuity of supply and manufacturer support.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance status and REACH Unaffected designation, ensuring compatibility with current environmental and regulatory requirements. The RMC58MMST carries ECCN classification EAR99 and HTSUS code 8536.69.4040, providing clear export and tariff classification.

Electrical and Mechanical Specifications: The RMC58MMST maintains all critical electrical and mechanical parameters required for direct substitution, including identical position count, pitch, contact finish specification, and operating temperature range. The connector interface with female edgecards remains functionally equivalent.

Compliance Certifications: Both parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the RMC58MMST directly replace the AMC58MMST in existing applications?

A: Yes. The RMC58MMST maintains identical electrical and mechanical specifications across all critical parameters: 116 positions, 2-row configuration, 0.100" pitch, male gender, dual read-out, gold contact finish (30.0µin), and -65°C to 200°C operating range. Both parts use identical insulation material (PPS) and flange configuration.

Q: What is the significance of the card thickness specification in the RMC58MMST?

A: The RMC58MMST specifies a card thickness of 0.062" (1.57mm). This parameter defines the physical dimension of the female edgecard with which the connector interfaces. This specification does not affect the electrical compatibility or substitution capability.

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

A: Yes. The AMC58MMST uses beryllium copper contacts, while the RMC58MMST uses phosphor bronze contacts. Both materials are gold-plated to the same finish thickness (30.0µin) and maintain equivalent electrical performance within the specified operating parameters.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both the AMC58MMST and RMC58MMST are ROHS3 compliant and REACH Unaffected. The RMC58MMST carries explicit ECCN and HTSUS classifications for regulatory documentation purposes.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Why is the AMC58MMST classified as obsolete?

A: The AMC58MMST is classified as obsolete by the manufacturer. The RMC58MMST represents the active product line continuation, providing equivalent functionality with ongoing manufacturer support and supply availability.

Q: Are the mounting configurations identical between these parts?

A: Both parts feature flush mount configuration with top opening and threaded insert (4-40). The RMC58MMST specifies Through Hole mounting type, while the AMC58MMST does not specify this parameter. Both use solder termination.
