AMC04MMSN Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC04MMSN is an 8-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 gold-plated beryllium copper contacts and operates across a temperature range of -65°C to 200°C. The AMC04MMSN is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for new production and field service applications.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC04MMSN with the active RMC04MMSN is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility:

• Identical connector type (male card edge connector)
• Identical number of positions (8 total)
• Identical pitch specification (0.100" / 2.54mm)
• Identical row configuration (2 rows, 4 positions per row)
• Identical read-out configuration (dual)
• Identical contact finish specification (gold plating at 30.0µin thickness)
• Identical operating temperature range (-65°C to 200°C)

Mechanical Compatibility:

• Identical termination method (solder)
• Identical insulation material (Polyphenylene Sulfide)
• Identical interface specification (fits female edgecards)

Compliance Compatibility:

• Both parts maintain ROHS3 compliance
• Both parts maintain MSL 1 (Unlimited) rating
• Both parts are REACH unaffected

Differences Noted: The RMC04MMSN introduces a specified card thickness of 0.062" (1.57mm) and includes through-hole mounting designation, with contact material specified as phosphor bronze rather than beryllium copper. These differences do not preclude substitution within standard card edge connector applications.

Engineering Selection Recommendations

The RMC04MMSN serves as the direct active equivalent for the obsolete AMC04MMSN. Selection of the RMC04MMSN is supported by the following engineering factors:

Product Status: The RMC04MMSN maintains active product status with current manufacturing and inventory availability (701 pieces in stock), whereas the AMC04MMSN is obsolete. This ensures long-term supply chain continuity and eliminates obsolescence risk.

Compliance Certification: Both parts maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production environments.

Electrical and Mechanical Specifications: The RMC04MMSN preserves all critical electrical parameters including connector type, position count, pitch, row configuration, contact finish specification, and operating temperature range. Mechanical compatibility is maintained through identical termination method and insulation material.

Manufacturing Continuity: Both parts originate from the same manufacturer (Sullins Connector Solutions), ensuring design consistency and manufacturing process alignment.

For applications currently utilizing the AMC04MMSN, direct substitution with the RMC04MMSN is supported without design modification.

Frequently Asked Questions (FAQ)

Q: Can the RMC04MMSN directly replace the AMC04MMSN in existing designs?

A: Yes. The RMC04MMSN maintains electrical and mechanical compatibility across all critical parameters including connector type, position count, pitch, row configuration, contact finish, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the primary reason for substitution?

A: The AMC04MMSN is classified as obsolete. The RMC04MMSN is the active equivalent part from the same manufacturer, ensuring ongoing component availability and supply chain continuity.

Q: Are there differences in contact material between these parts?

A: Yes. The AMC04MMSN specifies beryllium copper contacts, while the RMC04MMSN specifies phosphor bronze contacts. Both materials are suitable for gold-plated card edge connector applications and maintain the specified contact finish thickness of 30.0µin (0.76µm).
