AMC44MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC44MMSD is an 88-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 AMC44MMSD is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and legacy system requirements where this connector type remains in service.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC44MMSD is evaluated based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Number of Positions: 88 (fixed requirement)
• Number of Rows: 2 (fixed requirement)
• Pitch: 0.100" (2.54mm) (fixed requirement)
• Gender: Male (fixed requirement)
• Card Type: Fits Female Edgecards (fixed requirement)
• Read Out: Dual (fixed requirement)
• Contact Finish: Gold (fixed requirement)
• Contact Finish Thickness: 30.0µin (0.76µm) (fixed requirement)
• Operating Temperature Range: -65°C ~ 200°C (fixed requirement)
• Insulation Material: Polyphenylene Sulfide (PPS) (fixed requirement)
• Termination: Solder (fixed requirement)
• RoHS Status: ROHS3 Compliant (fixed requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (fixed requirement)

Parameters Permitting Variation:

• Contact Material (Beryllium Copper vs. Phosphor Bronze)
• Flange Feature configuration (Side Opening vs. Top Opening)
• Card Thickness specification
• Mounting Type designation
• Color
• Product Status (Obsolete vs. Active)

The RMC44MMSD meets all primary compatibility criteria and serves as a direct substitute for the AMC44MMSD.

Parameter Comparison

Engineering Selection Recommendations

The RMC44MMSD is the direct substitute for the obsolete AMC44MMSD. Both connectors are manufactured by Sullins Connector Solutions and maintain identical electrical and mechanical specifications across all critical parameters: 88-position dual read-out configuration, 0.100" pitch, gold contact finish at 30.0µin thickness, -65°C to 200°C operating temperature range, and PPS insulation material.

Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with current manufacturing and environmental standards. The RMC44MMSD carries active product status, providing assured availability and ongoing manufacturer support compared to the obsolete AMC44MMSD.

Differences in contact material (Phosphor Bronze vs. Beryllium Copper), flange opening orientation (Top Opening vs. Side Opening), and mounting type designation do not affect functional compatibility with female edgecards. The RMC44MMSD's specified card thickness of 0.062" (1.57mm) and Through Hole mounting type provide defined mechanical parameters for the active product variant.

Frequently Asked Questions (FAQ)

Q: Can the RMC44MMSD directly replace the AMC44MMSD in existing applications?

A: Yes. The RMC44MMSD meets all critical electrical and mechanical specifications of the AMC44MMSD, including position count, pitch, contact finish, operating temperature range, and insulation material. Both connectors interface identically with 88-position female edgecards.

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

A: The AMC44MMSD uses Beryllium Copper contacts while the RMC44MMSD uses Phosphor Bronze contacts. Both materials are standard for card edge connectors and provide equivalent electrical performance when combined with identical gold plating specifications (30.0µin thickness).

Q: How do the flange feature differences affect compatibility?

A: The AMC44MMSD features Side Opening flange configuration while the RMC44MMSD features Top Opening configuration. This difference relates to the physical orientation of the connector body during installation but does not affect electrical or mechanical compatibility with female edgecards.

Q: Why is the RMC44MMSD listed as active while the AMC44MMSD is obsolete?

A: The RMC44MMSD represents the current production variant of this connector family from Sullins Connector Solutions. The AMC44MMSD has been discontinued. The RMC44MMSD provides equivalent functionality with assured long-term availability.

Q: Are both connectors compliant with current environmental and regulatory standards?

A: Yes. Both the AMC44MMSD and RMC44MMSD are ROHS3 compliant and REACH unaffected. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage conditions.

Q: What is the specified card thickness for each connector?

A: The RMC44MMSD specifies 0.062" (1.57mm) card thickness. The AMC44MMSD does not include a specified card thickness parameter in available documentation. Both connectors are designed to interface with standard female edgecards at 0.100" pitch.
