AMC34MMST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC34MMST is a 68-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 AMC34MMST is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC34MMST with the active RMC34MMST is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Identical 68-position configuration with 0.100" (2.54mm) pitch
• Dual read-out functionality maintained
• Gold contact finish with identical 30.0µin (0.76µm) thickness
• Equivalent operating temperature range (-65°C ~ 200°C)
• Both ROHS3 compliant and MSL 1 rated

Mechanical Compatibility:

• Male gender connector for female edgecard interface
• Two-row configuration preserved
• Identical flange feature specification (Flush Mount, Top Opening, Threaded Insert, 4-40)
• Polyphenylene Sulfide (PPS) insulation material maintained
• Solder termination type consistent

Allowable Variations:

• Contact material differs (Beryllium Copper to Phosphor Bronze) within acceptable electrical performance parameters for this connector class
• Card thickness specification added in substitute (0.062" / 1.57mm)
• Mounting type specified as Through Hole in substitute
• Color designation (Black) added in substitute
• ECCN classification updated from OBSOLETE to EAR99

Parameter Comparison

Engineering Selection Recommendations

The RMC34MMST serves as the direct active equivalent for the obsolete AMC34MMST. Selection of the RMC34MMST is appropriate for the following reasons:

Compliance and Availability: The RMC34MMST maintains ROHS3 compliance and REACH unaffected status, consistent with the original part. Active product status ensures ongoing availability and supply chain continuity, eliminating obsolescence risk associated with the AMC34MMST.

Electrical and Mechanical Equivalence: The substitute part preserves all critical electrical parameters including 68-position configuration, 0.100" pitch, dual read-out, gold contact finish with identical thickness specification, and operating temperature range. Mechanical compatibility is maintained through identical flange features, mounting configuration, and insulation material.

Regulatory Classification: The RMC34MMST carries EAR99 ECCN classification with HTSUS code 8536.69.4040, providing clear regulatory documentation for procurement and export purposes.

Frequently Asked Questions (FAQ)

Q: Can the RMC34MMST directly replace the AMC34MMST in existing designs?

A: Yes. The RMC34MMST is electrically and mechanically equivalent to the AMC34MMST across all critical parameters: 68-position configuration, 0.100" pitch, dual read-out, gold contact finish, operating temperature range, and flange specifications. Both connectors interface with identical female edgecard configurations.

Q: What is the difference in contact material between these parts?

A: The AMC34MMST uses beryllium copper contacts, while the RMC34MMST uses phosphor bronze contacts. Both materials provide equivalent electrical performance for this connector class and maintain the same gold finish thickness specification of 30.0µin (0.76µm).

Q: Does the RMC34MMST specify a card thickness requirement?

A: Yes. The RMC34MMST specifies 0.062" (1.57mm) card thickness. This specification defines the edgecard thickness for which the connector is designed. Verify that existing edgecards conform to this thickness specification.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The RMC34MMST carries EAR99 ECCN classification, providing explicit regulatory documentation. The AMC34MMST is classified as obsolete and should not be used for new designs.

Q: What is the mounting configuration for the RMC34MMST?

A: The RMC34MMST is specified as Through Hole mounting with flush mount flange, top opening, and threaded insert (4-40). This configuration matches the mechanical interface of the original AMC34MMST.

Q: Is the RMC34MMST available in stock?

A: The RMC34MMST is an active product with 695 pieces in new original stock, ensuring availability for immediate procurement and production requirements.
