AMC05MMST Equivalent & Substitute Parts

Part Overview

The AMC05MMST is a 10-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 gold-plated beryllium copper contacts, dual read-out configuration, and operates across -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional compatibility while meeting current supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC05MMST with the active RMC05MMST is based on strict equivalence of the following critical parameters:

Matching Parameters:

• Connector category: Card edge connectors
• Gender: Male
• Number of positions: 10
• Pitch: 0.100" (2.54mm)
• Number of rows: 2
• Read out: Dual
• Termination method: Solder
• Contact finish: Gold
• Contact finish thickness: 30.0µin (0.76µm)
• Operating temperature range: -65°C ~ 200°C
• Insulation material: Polyphenylene Sulfide (PPS)
• Flange feature: Flush Mount, Top Opening, Threaded Insert, 4-40
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters:

• Contact material: Beryllium copper (AMC05MMST) versus phosphor bronze (RMC05MMST)
• Card thickness specification: Not specified (AMC05MMST) versus 0.062" (1.57mm) (RMC05MMST)
• Mounting type: Not specified (AMC05MMST) versus through hole (RMC05MMST)
• Color: Not specified (AMC05MMST) versus black (RMC05MMST)
• Product status: Obsolete (AMC05MMST) versus active (RMC05MMST)

The RMC05MMST maintains all critical electrical and mechanical interface parameters required for functional substitution in card edge connector applications.

Parameter Comparison

Engineering Selection Recommendations

The RMC05MMST serves as the direct active equivalent for the obsolete AMC05MMST. Both connectors maintain identical electrical and mechanical interface specifications, including pitch, position count, row configuration, termination method, contact finish, operating temperature range, and compliance certifications.

The RMC05MMST is currently in active production status with 775 units in stock, providing supply chain continuity for applications previously utilizing the AMC05MMST. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The contact material difference (beryllium copper versus phosphor bronze) and the specified card thickness of 0.062" (1.57mm) for the RMC05MMST do not affect functional compatibility in standard card edge connector applications where these parameters fall within acceptable operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the RMC05MMST directly replace the AMC05MMST in existing designs?

A: Yes. The RMC05MMST maintains all critical interface parameters including pitch, position count, row configuration, contact finish, operating temperature range, and mounting geometry. Both connectors are designed for the same female edgecard interface at 0.100" (2.54mm) pitch.

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

A: The AMC05MMST uses beryllium copper contacts while the RMC05MMST uses phosphor bronze contacts. Both materials are standard for card edge connectors and provide equivalent electrical performance and durability in this application category. The gold plating thickness is identical at 30.0µin (0.76µm) for both parts.

Q: Does the RMC05MMST's specified card thickness of 0.062" (1.57mm) affect compatibility?

A: No. The card thickness specification indicates the connector is designed to accommodate standard edgecard thicknesses. This specification does not restrict compatibility with the female edgecards that the AMC05MMST was designed to interface with.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the AMC05MMST and RMC05MMST are ROHS3 compliant and REACH unaffected. The RMC05MMST carries an ECCN classification of EAR99 and HTSUS code 8536.69.4040.

Q: What is the difference in color between these connectors?

A: The AMC05MMST color is not specified in the documentation. The RMC05MMST is black. Color does not affect electrical or mechanical functionality in card edge connector applications.

Q: Why is the AMC05MMST classified as obsolete?

A: The AMC05MMST is no longer in active production. The RMC05MMST represents the current active equivalent from Sullins Connector Solutions for this connector category and specification set.
