AMC19MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC19MMSD is a 38-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 AMC19MMSD is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and replacement requirements for legacy systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC19MMSD is evaluated based on the following critical parameters that determine functional compatibility:

Core Compatibility Parameters:

• Number of positions and row configuration (38 positions, 2 rows, 19 per row)
• Pitch specification (0.100" / 2.54mm)
• Connector gender (Male)
• Card interface type (Fits Female Edgecards)
• Read-out configuration (Dual)
• Termination method (Solder)
• Contact finish specification (Gold plating)
• Operating temperature range (-65°C to 200°C)
• Insulation material (Polyphenylene Sulfide)

The RMC19MMSD from Sullins Connector Solutions maintains these core parameters while offering active product status and current availability. Variations in contact material (phosphor bronze versus beryllium copper), flange opening orientation (top opening versus side opening), and color designation do not prevent functional substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The RMC19MMSD serves as a direct functional substitute for the obsolete AMC19MMSD. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 38-position configuration, 0.100" pitch, dual read-out, gold contact finish at 30.0µin thickness, solder termination, and -65°C to 200°C operating temperature range.

The RMC19MMSD offers the advantage of active product status with current manufacturing and availability (734 pcs in stock versus 1040 pcs of the obsolete AMC19MMSD). Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new applications and legacy system support.

Differences in contact material (phosphor bronze in RMC19MMSD versus beryllium copper in AMC19MMSD) and flange opening orientation (top opening versus side opening) represent design variations that do not compromise functional compatibility when interfacing with standard female edgecard receptacles. The specified card thickness of 0.062" (1.57mm) for the RMC19MMSD aligns with industry-standard edgecard dimensions.

Frequently Asked Questions (FAQ)

Q: Can the RMC19MMSD directly replace the AMC19MMSD in existing applications?

A: Yes. Both connectors share identical position count (38), pitch (0.100"), row configuration (2 rows of 19), read-out type (dual), contact finish (gold at 30.0µin), termination method (solder), and operating temperature range (-65°C to 200°C). The connectors are mechanically and electrically compatible with the same female edgecard receptacles.

Q: What is the significance of the contact material difference between beryllium copper and phosphor bronze?

A: Both materials provide acceptable electrical conductivity and mechanical spring properties for card edge connector applications. The contact finish (gold plating at 30.0µin) is identical on both parts, which is the primary factor determining electrical performance and corrosion resistance at the interface.

Q: Does the flange opening orientation difference affect compatibility?

A: The flange opening orientation (side opening on AMC19MMSD versus top opening on RMC19MMSD) relates to the physical mounting approach and board layout considerations. Both maintain the same flush mount configuration with 0.125" (3.18mm) diameter unthreaded flange. Selection depends on the specific board layout and mounting requirements of the application.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the AMC19MMSD and RMC19MMSD are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the card thickness specification for the RMC19MMSD?

A: The RMC19MMSD is specified for 0.062" (1.57mm) card thickness, which represents the standard dimension for edgecard applications in this connector class.

Q: Why is the AMC19MMSD classified as obsolete?

A: The AMC19MMSD has been discontinued by the manufacturer. The RMC19MMSD represents the current active equivalent from Sullins Connector Solutions for this connector type and position count.
