AMC54MMST Equivalent & Substitute Parts

Part Overview

The AMC54MMST is a 108-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 with existing applications.

Key Parameters

Substitute Part Grouping Explanation

The RMC54MMST qualifies as a direct substitute for the AMC54MMST based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• Number of positions: 108
• Gender: Male
• Pitch: 0.100" (2.54mm)
• Number of rows: 2
• Read out: Dual
• Contact finish: Gold at 30.0µin (0.76µm)
• Termination method: Solder
• 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 (AMC54MMST) versus Phosphor Bronze (RMC54MMST)
• Card thickness specification: Not specified (AMC54MMST) versus 0.062" (1.57mm) (RMC54MMST)
• Mounting type: Not specified (AMC54MMST) versus Through Hole (RMC54MMST)
• Color: Not specified (AMC54MMST) versus Black (RMC54MMST)
• Product status: Obsolete (AMC54MMST) versus Active (RMC54MMST)

The RMC54MMST maintains all critical electrical and mechanical interface parameters required for direct substitution in applications originally designed for the AMC54MMST.

Parameter Comparison

Engineering Selection Recommendations

The RMC54MMST is the appropriate substitute for the obsolete AMC54MMST. Both connectors are manufactured by Sullins Connector Solutions and maintain identical electrical and mechanical interface specifications across all critical parameters. The RMC54MMST carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts satisfy ROHS3 compliance requirements and carry unlimited moisture sensitivity classification (MSL 1), making them suitable for standard industrial and commercial applications without special handling protocols. The RMC54MMST's active status provides superior long-term availability compared to the obsolete AMC54MMST.

Frequently Asked Questions (FAQ)

Q: Can the RMC54MMST directly replace the AMC54MMST in existing designs?

A: Yes. The RMC54MMST maintains identical pitch (0.100"), position count (108), row configuration (2), read-out type (dual), contact finish (gold at 30.0µin), termination method (solder), operating temperature range (-65°C to 200°C), and flange geometry. These parameters define the mechanical and electrical interface compatibility.

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

A: Both materials provide suitable electrical conductivity and mechanical properties for card edge connector applications. The contact finish (gold plating) is identical at 30.0µin thickness, which is the primary determinant of contact performance and corrosion resistance in this application.

Q: Does the RMC54MMST's specified card thickness of 0.062" (1.57mm) affect compatibility?

A: The card thickness specification on the RMC54MMST indicates the connector is designed for 0.062" edgecards. This parameter should be verified against the actual edgecard thickness in the target application to ensure proper mechanical fit and electrical contact.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity). The RMC54MMST carries ECCN classification EAR99 and HTSUS code 8536.69.4040, while the AMC54MMST is marked as obsolete. For new designs and procurement, the RMC54MMST's active status and current compliance documentation provide superior regulatory support.

Q: What is the significance of the color difference?

A: The RMC54MMST is specified as black, while the AMC54MMST color is not specified. Color is a cosmetic parameter that does not affect electrical or mechanical function. The black color of the RMC54MMST is a standard industry specification for this connector series.
