AMC24MMST Equivalent & Substitute Parts

Part Overview

The AMC24MMST is a 48-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 AMC24MMST is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

The RMC24MMST qualifies as a direct substitute for the AMC24MMST based on the following critical parameters:

Matching Parameters:

• 48-position male card edge connector configuration
• 0.100" (2.54mm) pitch spacing
• Dual read-out design
• 2-row arrangement
• Gold contact finish at 30.0µin (0.76µm) thickness
• Solder termination
• -65°C to 200°C operating temperature range
• Polyphenylene Sulfide (PPS) insulation material
• Flush Mount, Top Opening, Threaded Insert, 4-40 flange feature
• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

Differentiating Parameters:

• Contact material: Phosphor Bronze (RMC24MMST) versus Beryllium Copper (AMC24MMST)
• Card thickness specification: 0.062" (1.57mm) defined for RMC24MMST
• Mounting type: Through Hole designation for RMC24MMST
• Product status: Active (RMC24MMST) versus Obsolete (AMC24MMST)
• Color: Black (RMC24MMST)

The RMC24MMST maintains electrical and mechanical compatibility through identical pitch, position count, row configuration, contact finish specification, and operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The RMC24MMST is the active equivalent replacement for the obsolete AMC24MMST. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 48-position configuration, 0.100" pitch, dual read-out, gold contact finish at 30.0µin thickness, solder termination, and -65°C to 200°C operating range.

The RMC24MMST carries active product status with full ROHS3 compliance and Moisture Sensitivity Level 1 rating, ensuring availability and regulatory alignment for current production. The contact material difference (Phosphor Bronze versus Beryllium Copper) and defined card thickness specification (0.062") in the RMC24MMST represent refinements in the connector design while maintaining functional compatibility with female edgecard interfaces.

Both parts are manufactured by Sullins Connector Solutions, ensuring consistent quality and design heritage. Selection of the RMC24MMST eliminates obsolescence risk while preserving all electrical and mechanical interface requirements of the original AMC24MMST specification.

Frequently Asked Questions (FAQ)

Q: Can the RMC24MMST directly replace the AMC24MMST in existing designs?

A: Yes. The RMC24MMST maintains identical pitch (0.100"), position count (48), row configuration (2), contact finish specification (Gold, 30.0µin), and operating temperature range (-65°C to 200°C). Both connectors interface with female edgecards using the same flange feature (Flush Mount, Top Opening, Threaded Insert, 4-40).

Q: What is the significance of the contact material difference between these connectors?

A: The AMC24MMST uses Beryllium Copper contacts while the RMC24MMST uses Phosphor Bronze contacts. Both materials are specified with identical gold plating thickness (30.0µin) and maintain the same electrical and mechanical performance characteristics for card edge connector applications.

Q: Does the RMC24MMST specify a card thickness requirement?

A: Yes. The RMC24MMST is specified for 0.062" (1.57mm) card thickness. This specification ensures proper contact engagement with female edgecards of this thickness. The original AMC24MMST does not specify a card thickness parameter.

Q: Are both connectors compliant with current regulatory standards?

A: Yes. Both the AMC24MMST and RMC24MMST are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). The RMC24MMST carries active product status, ensuring ongoing compliance and availability.

Q: What is the difference in mounting type between these connectors?

A: The RMC24MMST is designated as Through Hole mounting type. The AMC24MMST does not specify a mounting type parameter. Both connectors use solder termination and the same flange feature configuration.

Q: Why is the AMC24MMST classified as obsolete?

A: The AMC24MMST is listed as obsolete product status. The RMC24MMST represents the active equivalent, ensuring continued availability and support for applications requiring 48-position male card edge connectors at 0.100" pitch.
