AMC13MMST Equivalent & Substitute Parts

Part Overview

The AMC13MMST is a 26-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 the temperature range of -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility while ensuring continued supply chain availability and compliance with current regulatory standards.

Key Parameters

Substitute Part Grouping Explanation

The RMC13MMST qualifies as a direct substitute for the AMC13MMST based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• 26-position male 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
• Polyphenylene Sulfide (PPS) insulation material
• Flush mount flange with top opening and 4-40 threaded insert
• Operating temperature range of -65°C to 200°C
• ROHS3 compliance
• MSL 1 rating

Differences:

• RMC13MMST is active product status versus obsolete AMC13MMST
• RMC13MMST specifies card thickness of 0.062" (1.57mm)
• RMC13MMST contact material is phosphor bronze versus beryllium copper
• RMC13MMST includes through-hole mounting designation
• RMC13MMST is black colored

These differences do not preclude substitution, as the connector interface geometry, electrical performance characteristics, and environmental ratings remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

The RMC13MMST is the appropriate substitute for the obsolete AMC13MMST. The substitute part maintains all critical electrical and mechanical interface parameters required for functional compatibility with female edgecards. Both connectors are ROHS3 compliant and carry MSL 1 ratings, ensuring compatibility with current manufacturing and environmental standards.

The RMC13MMST is an active product with current inventory availability, eliminating supply chain risk associated with the obsolete AMC13MMST. The active product status of the RMC13MMST ensures access to technical support, documentation, and continued manufacturing capability.

The contact material difference between beryllium copper and phosphor bronze does not impact substitution viability, as both materials provide equivalent electrical conductivity and contact reliability within the specified operating temperature range. The specified card thickness of 0.062" (1.57mm) for the RMC13MMST represents a standard thickness for card edge applications and does not restrict compatibility.

Frequently Asked Questions (FAQ)

Q: Can the RMC13MMST directly replace the AMC13MMST in existing designs?

A: Yes. The RMC13MMST maintains identical connector geometry, pitch spacing, position count, and electrical interface specifications. The connector will interface with the same female edgecard designs without modification.

Q: What is the significance of the contact material difference between beryllium copper and phosphor bronze?

A: Both materials provide suitable electrical conductivity and contact reliability for card edge connector applications. The phosphor bronze contact material in the RMC13MMST is fully compatible with the specified operating temperature range and gold plating thickness.

Q: Does the specified card thickness of 0.062" (1.57mm) for the RMC13MMST affect compatibility?

A: No. The card thickness specification indicates the connector is designed for standard 0.062" edgecards. This is a common thickness in card edge connector applications and does not restrict compatibility with existing female edgecard designs.

Q: Are both connectors compliant with current regulatory standards?

A: Yes. Both the AMC13MMST and RMC13MMST are ROHS3 compliant and carry MSL 1 ratings, meeting current environmental and manufacturing standards.

Q: What is the advantage of selecting the RMC13MMST over the obsolete AMC13MMST?

A: The RMC13MMST is an active product with current manufacturing and inventory availability. Selection of the active product eliminates supply chain discontinuity and ensures access to technical documentation and support.

Q: Are the solder termination specifications identical between both connectors?

A: Yes. Both connectors utilize solder termination and are compatible with standard PCB assembly processes.
