AMC11MMST Equivalent & Substitute Parts

Part Overview

The AMC11MMST is a 22-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 -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 availability and compliance with current standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC11MMST with the active RMC11MMST is based on alignment of the following critical parameters:

Matched Parameters:

• Number of positions (22) and row configuration (2 rows)
• Pitch specification (0.100" / 2.54mm)
• Gender (Male) and card type compatibility (Fits Female Edgecards)
• Dual read-out functionality
• Solder termination method
• Gold contact finish at 30.0µin thickness
• Operating temperature range (-65°C ~ 200°C)
• Insulation material (Polyphenylene Sulfide)
• Flange feature configuration (Flush Mount, Top Opening, Threaded Insert, 4-40)
• Compliance certifications (ROHS3, MSL 1)

Differing Parameters:

• Contact material (Beryllium Copper vs. Phosphor Bronze)
• Card thickness specification (not specified vs. 0.062")
• Mounting type (not specified vs. Through Hole)
• Color (not specified vs. Black)
• Product status (Obsolete vs. Active)

The RMC11MMST maintains functional equivalence through identical connector geometry, electrical interface specifications, and environmental ratings. Differences in contact material and mounting type do not preclude substitution within standard card edge connector applications.

Parameter Comparison

Engineering Selection Recommendations

The RMC11MMST is the direct active equivalent for the obsolete AMC11MMST. Selection of the RMC11MMST is supported by the following factors:

Product Status: The RMC11MMST maintains active product status with current manufacturing and supply chain availability, whereas the AMC11MMST is classified as obsolete.

Compliance Alignment: Both connectors maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with current regulatory requirements and manufacturing standards.

Functional Equivalence: Identical connector geometry, pitch, position count, and electrical interface specifications ensure direct functional substitution in card edge connector applications.

Environmental Specifications: Matching operating temperature range (-65°C ~ 200°C) and insulation material (PPS) maintain performance across equivalent thermal and environmental conditions.

Contact Specifications: Gold plating at identical thickness (30.0µin) ensures equivalent electrical contact performance and corrosion resistance.

The RMC11MMST is the appropriate selection for new designs and replacement applications requiring the AMC11MMST specification.

Frequently Asked Questions (FAQ)

Q: Can the RMC11MMST directly replace the AMC11MMST in existing applications?

A: Yes. The RMC11MMST maintains identical connector geometry, pitch, position configuration, and electrical interface specifications. Both connectors interface with female edgecards at 0.100" pitch with dual read-out functionality and solder termination.

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 performance for card edge connector applications. Phosphor bronze, used in the RMC11MMST, is a standard contact material in active connector production and maintains equivalent performance characteristics within the specified operating temperature range.

Q: Does the RMC11MMST card thickness specification of 0.062" affect compatibility?

A: The RMC11MMST is specified for 0.062" (1.57mm) card thickness. This specification indicates the connector design tolerance for female edgecard thickness. Compatibility depends on the actual card thickness in the application. Standard 0.062" thickness edgecards are compatible with this connector.

Q: Are there compliance differences between the two connectors?

A: No. Both the AMC11MMST and RMC11MMST maintain ROHS3 compliance and MSL 1 rating. The RMC11MMST carries ECCN EAR99 classification and HTSUS code 8536.69.4040, indicating active product status with current export and tariff classifications.

Q: What is the significance of the "Through Hole" mounting type specification for the RMC11MMST?

A: The Through Hole mounting type indicates the connector is designed for solder termination through printed circuit board holes, which aligns with the solder termination method specified for both connectors. This is standard for card edge connector applications.

Q: Does the black color of the RMC11MMST affect electrical or mechanical performance?

A: No. Color is a cosmetic specification that does not affect electrical performance, mechanical compatibility, or functional operation. The black insulation material is standard for active production connectors.
