AMC33MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC33MMSD is a 66-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 AMC33MMSD 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 AMC33MMSD is determined by the following critical parameters that must remain consistent:

Mandatory Matching Parameters:

• Number of Positions: 66
• Pitch: 0.100" (2.54mm)
• Gender: Male
• Read Out Configuration: Dual
• Termination Method: Solder
• Contact Finish: Gold at 30.0µin (0.76µm)
• Operating Temperature Range: -65°C ~ 200°C
• Insulation Material: Polyphenylene Sulfide (PPS)
• RoHS3 Compliance

Parameters Permitted to Vary:

• Product Status (Obsolete to Active)
• Contact Material (Beryllium Copper to Phosphor Bronze)
• Flange Feature configuration (Side Opening to Top Opening)
• Mounting Type (unspecified to Through Hole)
• Color (unspecified to Black)
• Card Thickness specification (unspecified to 0.062")

The RMC33MMSD meets all mandatory matching parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The RMC33MMSD is a direct functional substitute for the obsolete AMC33MMSD. Both connectors maintain identical electrical and mechanical specifications for the critical parameters governing card edge connector compatibility: 66-position configuration, 0.100" pitch, dual read-out, solder termination, and gold contact finish at 30.0µin thickness.

The RMC33MMSD offers the advantage of active product status with current manufacturing support and documented availability. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility with modern assembly and operational requirements.

The contact material difference (Beryllium Copper to Phosphor Bronze) and flange opening orientation (Side Opening to Top Opening) represent design refinements in the active product line. These variations do not affect electrical performance or mechanical fit with standard female edgecard receptacles at 0.100" pitch.

Frequently Asked Questions (FAQ)

Q: Can the RMC33MMSD directly replace the AMC33MMSD in existing applications?

A: Yes. Both connectors share identical specifications for position count (66), pitch (0.100"), read-out configuration (dual), termination method (solder), contact finish (gold at 30.0µin), and operating temperature range (-65°C to 200°C). The RMC33MMSD is designed as a functional equivalent for the obsolete AMC33MMSD.

Q: What is the significance of the contact material change from Beryllium Copper to Phosphor Bronze?

A: Both materials provide suitable electrical conductivity and mechanical properties for card edge connector applications. Phosphor Bronze in the RMC33MMSD represents the current manufacturing standard for this connector series while maintaining equivalent performance characteristics.

Q: Does the flange feature difference (Side Opening vs. Top Opening) affect compatibility?

A: The flange opening orientation does not affect electrical or mechanical compatibility with standard female edgecard receptacles. Both configurations maintain the same 0.125" (3.18mm) diameter flush mount design and unthreaded specification.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the AMC33MMSD and RMC33MMSD are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and assembly standards.

Q: What is the significance of the specified card thickness (0.062") for the RMC33MMSD?

A: The 0.062" (1.57mm) card thickness specification for the RMC33MMSD defines the mechanical tolerance for female edgecard compatibility. This specification ensures proper contact engagement and retention within the connector body.

Q: Is the RMC33MMSD available in current inventory?

A: The RMC33MMSD maintains active product status with documented availability. The AMC33MMSD is classified as obsolete and subject to limited inventory constraints.
