AMC08MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC08MMSD is a 16-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 -65°C to 200°C. The AMC08MMSD is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC08MMSD with the active RMC08MMSD is based on electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Parameters:

• 16-position connector configuration
• 0.100" (2.54mm) pitch spacing
• Dual read-out functionality
• Solder termination method
• Gold contact finish at 30.0µin thickness
• Operating temperature range -65°C ~ 200°C
• Polyphenylene Sulfide insulation material

Mechanical Compatibility Parameters:

• Male gender connector
• Fits female edgecards
• Flush mount flange with 0.125" (3.18mm) diameter
• Unthreaded flange design

Compliance Parameters:

• ROHS3 compliance maintained
• Moisture Sensitivity Level 1 (Unlimited)
• REACH unaffected status

The RMC08MMSD maintains functional equivalence while introducing design improvements including active product status, specified card thickness accommodation (0.062"), through-hole mounting capability, and phosphor bronze contact material with enhanced durability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The RMC08MMSD serves as the direct functional equivalent for the obsolete AMC08MMSD. Selection of the RMC08MMSD is supported by the following engineering criteria:

Product Status and Availability: The RMC08MMSD maintains active product status with confirmed inventory availability (781 pieces in stock), ensuring reliable component sourcing for current and future production requirements. The AMC08MMSD obsolete classification eliminates it as a viable long-term supply option.

Regulatory Compliance: Both connectors maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. Moisture Sensitivity Level 1 (Unlimited) classification on both parts eliminates moisture-related handling constraints.

Electrical and Mechanical Equivalence: The RMC08MMSD preserves all critical electrical parameters including 16-position configuration, 0.100" pitch, dual read-out, gold contact finish at specified thickness, and full operating temperature range. Mechanical compatibility is maintained through identical flange design, flush mount configuration, and solder termination method.

Design Improvements: The RMC08MMSD incorporates specified card thickness accommodation (0.062"), through-hole mounting capability, and phosphor bronze contact material, providing enhanced design definition and durability characteristics compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can the RMC08MMSD directly replace the AMC08MMSD in existing designs?

A: Yes. The RMC08MMSD maintains electrical and mechanical compatibility across all critical parameters including connector position count, pitch spacing, read-out configuration, termination method, contact finish specifications, operating temperature range, and insulation material. Both connectors interface with identical female edgecard configurations.

Q: What are the differences between the AMC08MMSD and RMC08MMSD?

A: The primary differences are product status (obsolete versus active), contact material (beryllium copper versus phosphor bronze), flange opening orientation (side opening versus top opening), and specified card thickness accommodation (unspecified versus 0.062"). Electrical performance and compliance characteristics remain equivalent.

Q: Are there any compatibility considerations for PCB layout or mounting?

A: The RMC08MMSD specifies through-hole mounting capability and accommodates 0.062" card thickness. The flange opening orientation differs (top opening versus side opening), which may affect mechanical access during assembly. Verify PCB layout accommodates the specified card thickness and mounting configuration.

Q: Do both connectors meet current regulatory requirements?

A: Yes. Both the AMC08MMSD and RMC08MMSD are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level 1 (Unlimited) on both parts eliminates moisture-related handling requirements.

Q: What is the significance of the contact material difference?

A: The AMC08MMSD uses beryllium copper contacts while the RMC08MMSD uses phosphor bronze contacts. Both materials are gold-plated at identical thickness (30.0µin) and support the full operating temperature range (-65°C ~ 200°C). Phosphor bronze provides enhanced durability characteristics in the RMC08MMSD.

Q: Is inventory availability a factor in component selection?

A: Yes. The RMC08MMSD maintains active inventory status with 781 pieces available, while the AMC08MMSD is obsolete with no ongoing supply. For new designs and production continuity, the RMC08MMSD is the appropriate selection.
