AMC59MMST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC59MMST is a 118-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards using a 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 AMC59MMST is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

The RMC59MMST qualifies as a direct substitute for the AMC59MMST based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• 118 total positions (59 positions per row, 2 rows)
• 0.100" (2.54mm) pitch spacing
• Male gender configuration
• Dual read-out functionality
• Fits female edgecards
• Gold contact finish at 30.0µin (0.76µm) thickness
• Operating temperature range of -65°C to 200°C
• Solder termination
• Polyphenylene Sulfide (PPS) insulation material
• Flush mount flange with top opening and 4-40 threaded insert
• ROHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)

Differing Parameters: The RMC59MMST introduces a specified card thickness of 0.062" (1.57mm), through-hole mounting type, phosphor bronze contact material, and black color. These differences do not prevent functional substitution when the specified card thickness is compatible with the application.

Parameter Comparison

Engineering Selection Recommendations

The RMC59MMST is the appropriate substitute for the obsolete AMC59MMST. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: position count, pitch, gender, read-out configuration, temperature range, and compliance certifications. The RMC59MMST carries active product status, ensuring availability for current and future production requirements.

Both components satisfy ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for electronic assemblies. The identical contact finish thickness and insulation material specifications ensure electrical performance parity in applications requiring the specified operating temperature range of -65°C to 200°C.

The RMC59MMST specifies a card thickness of 0.062" (1.57mm) and through-hole mounting configuration. Verification that the application accommodates these specifications is necessary prior to implementation. The phosphor bronze contact material in the RMC59MMST provides equivalent electrical performance to the beryllium copper contacts in the AMC59MMST under the specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the RMC59MMST directly replace the AMC59MMST in existing designs?

A: The RMC59MMST functions as a direct substitute when the application accommodates the specified card thickness of 0.062" (1.57mm) and through-hole mounting configuration. All critical electrical and mechanical parameters align between the two connectors.

Q: What is the significance of the different contact materials?

A: The AMC59MMST uses beryllium copper contacts while the RMC59MMST uses phosphor bronze contacts. Both materials provide equivalent electrical performance and durability under the specified operating temperature range of -65°C to 200°C with identical gold plating thickness.

Q: Are there compliance differences between these connectors?

A: Both connectors maintain ROHS3 compliance and REACH unaffected status. The RMC59MMST carries an ECCN classification of EAR99 and HTSUS code 8536.69.4040, while the AMC59MMST is classified as obsolete. These designations do not affect functional compatibility.

Q: What does the card thickness specification mean?

A: The RMC59MMST specifies a card thickness of 0.062" (1.57mm), indicating the thickness of the female edgecard with which it interfaces. The AMC59MMST does not specify this parameter. Confirmation that the application uses edgecards of this thickness is required for substitution.

Q: How do the mounting types differ?

A: The RMC59MMST specifies through-hole mounting, while the AMC59MMST does not specify a mounting type. Through-hole mounting indicates the connector is soldered directly to PCB through-holes. Verify that the PCB design accommodates through-hole termination.

Q: Are the temperature operating ranges identical?

A: Both connectors operate across the identical temperature range of -65°C to 200°C, ensuring thermal performance parity in applications requiring extended temperature operation.

Q: What is the Moisture Sensitivity Level significance?

A: Both connectors carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
