AMC41MMST Equivalent & Substitute Parts

Part Overview

The AMC41MMST is an 82-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 a temperature range of -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility with existing applications.

Key Parameters

Substitute Part Grouping Explanation

The RMC41MMST qualifies as a direct substitute for the AMC41MMST based on the following critical parameters:

Matching Parameters:

• 82-position configuration with dual read-out
• Male gender connector
• 0.100" (2.54mm) pitch spacing
• 2-row arrangement
• Solder termination method
• Gold contact finish at 30.0µin (0.76µm) thickness
• Identical operating temperature range (-65°C ~ 200°C)
• Polyphenylene Sulfide (PPS) insulation material
• Flush Mount, Top Opening, Threaded Insert, 4-40 flange configuration
• ROHS3 compliance and REACH unaffected status

Functional Equivalence: The RMC41MMST maintains all critical electrical and mechanical parameters required for direct substitution in applications designed for the AMC41MMST. Both connectors interface with identical female edgecard specifications and provide equivalent contact performance through gold plating.

Parameter Comparison

Engineering Selection Recommendations

The RMC41MMST is the appropriate substitute for the obsolete AMC41MMST in new designs and production applications. The substitute part maintains active product status with Sullins Connector Solutions, ensuring continued availability and supply chain reliability. Both parts satisfy ROHS3 compliance requirements and REACH regulatory status, supporting deployment in regulated industries.

The transition from AMC41MMST to RMC41MMST does not introduce electrical incompatibility. While the contact material differs (beryllium copper versus phosphor bronze), both materials provide equivalent gold-plated surface performance at the specified 30.0µin thickness. The RMC41MMST's documented card thickness specification of 0.062" (1.57mm) and through-hole mounting type provide additional design clarity for PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the RMC41MMST directly replace the AMC41MMST in existing assemblies?

A: Yes. The RMC41MMST provides direct functional replacement. Both connectors feature identical 82-position, dual read-out configuration with 0.100" pitch spacing, matching flange geometry, and equivalent operating temperature ranges. Solder termination and gold contact finish specifications are identical.

Q: What is the significance of the contact material difference between the two parts?

A: The AMC41MMST uses beryllium copper contacts while the RMC41MMST uses phosphor bronze contacts. Both materials are standard for card edge connectors and provide equivalent performance when gold-plated to the same 30.0µin thickness. The gold plating is the primary contact interface in both cases.

Q: Are there compatibility concerns with female edgecards designed for the AMC41MMST?

A: No. Both connectors are designed to interface with identical female edgecard specifications at 0.100" (2.54mm) pitch. The mechanical dimensions, flange configuration, and contact spacing are equivalent.

Q: Why is the RMC41MMST listed as active while the AMC41MMST is obsolete?

A: The AMC41MMST has been discontinued by Sullins Connector Solutions. The RMC41MMST represents the current active equivalent in the product line, ensuring ongoing availability for new production and replacement applications.

Q: Does the RMC41MMST meet the same regulatory requirements as the AMC41MMST?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, satisfying equivalent regulatory requirements for industrial and commercial applications.

Q: What is the significance of the card thickness specification on the RMC41MMST?

A: The RMC41MMST specifies a card thickness of 0.062" (1.57mm). This parameter defines the physical dimension of the female edgecard that the connector accommodates. This specification provides design clarity for PCB layout and mechanical integration.
