AMC35MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC35MMSD is a 70-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 with 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 for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

Substitution of the AMC35MMSD with the RMC35MMSD is based on equivalence across the following critical parameters:

Electrical Compatibility:

• Identical number of positions (70) and position arrangement (35 per row, 2 rows)
• Matching pitch specification (0.100" / 2.54mm)
• Dual read-out configuration maintained
• Gold contact finish with identical thickness (30.0µin)
• Identical operating temperature range (-65°C ~ 200°C)

Mechanical Compatibility:

• Same connector category (Card Edge Connectors)
• Identical gender (Male)
• Matching termination method (Solder)
• Identical insulation material (Polyphenylene Sulfide)
• Equivalent flange mounting configuration (Flush Mount, Unthreaded, 0.125" Dia)

Regulatory Compliance:

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

The RMC35MMSD represents an active product status alternative, addressing the obsolescence of the AMC35MMSD while maintaining functional and electrical equivalence for card edge connector applications.

Parameter Comparison

Engineering Selection Recommendations

The RMC35MMSD is the direct active equivalent for the obsolete AMC35MMSD. Both connectors maintain identical electrical specifications, pitch, position count, and operating temperature parameters. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

Both parts satisfy ROHS3 compliance requirements and carry identical moisture sensitivity ratings. The RMC35MMSD is suitable for direct substitution in applications currently utilizing the AMC35MMSD, provided that mechanical mounting orientation accommodates the difference in flange opening direction (side opening versus top opening).

The contact material difference (beryllium copper versus phosphor bronze) does not affect functional compatibility, as both materials provide equivalent electrical performance and gold plating specifications. The RMC35MMSD's active status makes it the appropriate selection for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the RMC35MMSD directly replace the AMC35MMSD in existing applications?

A: The RMC35MMSD is electrically and functionally equivalent to the AMC35MMSD across all critical parameters including position count, pitch, contact finish, and operating temperature range. Mechanical compatibility depends on PCB layout accommodation of the flange opening direction difference (side opening on AMC35MMSD versus top opening on RMC35MMSD).

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

A: The AMC35MMSD uses beryllium copper contacts while the RMC35MMSD uses phosphor bronze contacts. Both materials, when gold-plated to the specified thickness of 30.0µin (0.76µm), provide equivalent electrical performance and contact reliability for card edge connector applications.

Q: Are both parts compliant with current regulatory standards?

A: Both the AMC35MMSD and RMC35MMSD are ROHS3 compliant and REACH unaffected. Both carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Why is the AMC35MMSD classified as obsolete?

A: The AMC35MMSD is listed as obsolete, indicating it is no longer in active production. The RMC35MMSD represents the current active equivalent from Sullins Connector Solutions for this connector configuration.

Q: What is the difference in flange opening orientation?

A: The AMC35MMSD features a side opening flange configuration, while the RMC35MMSD features a top opening flange configuration. Both maintain flush mount design with identical 0.125" (3.18mm) diameter unthreaded specifications. PCB design must accommodate the specific opening orientation of the selected part.

Q: Are the pitch and position specifications identical between these connectors?

A: Both connectors maintain 0.100" (2.54mm) pitch with 70 total positions arranged as 35 positions per row across 2 rows. The dual read-out configuration is identical on both parts.
