AMC10MMST Equivalent & Substitute Parts

Part Overview

The AMC10MMST is a 20-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 electrical and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC10MMST with the active RMC10MMST is based on alignment of the following critical parameters:

Electrical Compatibility:

• Identical number of positions (20) and rows (2)
• Matching pitch specification (0.100" / 2.54mm)
• Dual read-out configuration maintained
• Gold contact finish with identical thickness (30.0µin / 0.76µm)
• Solder termination type preserved
• Identical operating temperature range (-65°C ~ 200°C)

Mechanical Compatibility:

• Same connector category (Card Edge Connector, Male)
• Identical flange feature specification (Flush Mount, Top Opening, Threaded Insert, 4-40)
• Matching insulation material (Polyphenylene Sulfide / PPS)
• Compatible with female edgecards

Compliance & Certification:

• Both parts maintain ROHS3 compliance
• Both parts classified as REACH Unaffected
• Both parts carry MSL 1 (Unlimited) rating

Identified Differences:

• Contact material: Beryllium Copper (AMC10MMST) versus Phosphor Bronze (RMC10MMST)
• Card thickness specification: Not specified (AMC10MMST) versus 0.062" (1.57mm) (RMC10MMST)
• Mounting type: Not specified (AMC10MMST) versus Through Hole (RMC10MMST)
• Color: Not specified (AMC10MMST) versus Black (RMC10MMST)
• Product status: Obsolete (AMC10MMST) versus Active (RMC10MMST)

Parameter Comparison

Engineering Selection Recommendations

The RMC10MMST serves as the active equivalent for the obsolete AMC10MMST. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 20-position dual read-out configuration, 0.100" pitch, gold contact finish, solder termination, and operating temperature range of -65°C to 200°C.

Both parts satisfy ROHS3 compliance requirements and carry identical moisture sensitivity ratings. The RMC10MMST is currently in active production status with documented inventory availability, whereas the AMC10MMST is classified as obsolete.

The contact material difference (Beryllium Copper versus Phosphor Bronze) and the specified card thickness of 0.062" (1.57mm) for the RMC10MMST do not preclude functional substitution, as both materials provide suitable electrical conductivity and contact reliability within the specified operating parameters. The Through Hole mounting type designation for the RMC10MMST aligns with standard solder termination practices for this connector category.

Frequently Asked Questions (FAQ)

Q: Can the RMC10MMST directly replace the AMC10MMST in existing designs?

A: Yes. The RMC10MMST maintains identical electrical and mechanical specifications across all critical parameters including position count, pitch, read-out configuration, contact finish, termination type, and operating temperature range. Both connectors interface with female edgecards using identical flange features and insulation materials.

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

A: The AMC10MMST uses Beryllium Copper contacts while the RMC10MMST uses Phosphor Bronze contacts. Both materials provide suitable electrical conductivity and contact reliability for card edge connector applications. The contact finish (gold plating at 30.0µin thickness) is identical on both parts, ensuring equivalent surface contact characteristics.

Q: Does the RMC10MMST card thickness specification of 0.062" (1.57mm) affect compatibility?

A: The specified card thickness for the RMC10MMST indicates the connector is designed for standard 0.062" edgecards. This specification does not preclude use with the connector; rather, it documents the intended application parameter. Compatibility depends on the female edgecard thickness in your application.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the AMC10MMST and RMC10MMST are ROHS3 compliant and classified as REACH Unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special handling requirements during storage or assembly.

Q: Why is the AMC10MMST classified as obsolete?

A: The AMC10MMST is listed as obsolete by the manufacturer. The RMC10MMST is the active production equivalent, currently manufactured and stocked. For new designs and ongoing applications, the RMC10MMST is the recommended selection.

Q: What is the difference between the mounting type specifications?

A: The AMC10MMST does not specify a mounting type, while the RMC10MMST is designated as Through Hole. Both connectors use solder termination. The Through Hole designation for the RMC10MMST indicates standard PCB mounting via plated through holes, which is the typical implementation for solder-terminated card edge connectors.
