AMC33MMST Equivalent & Substitute Parts

Part Overview

The AMC33MMST 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, gold-plated beryllium copper contacts, and operates across -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure component availability for new production and field service applications.

Substitute Part Grouping Explanation

The RMC33MMST qualifies as a direct substitute for the AMC33MMST based on alignment across all critical electrical and mechanical parameters that define functional compatibility. Both connectors maintain identical specifications for number of positions (66), gender (male), pitch (0.100"), row configuration (2 rows), read-out type (dual), termination method (solder), contact finish (gold at 30.0µin thickness), operating temperature range (-65°C to 200°C), insulation material (PPS), and flange features (flush mount, top opening, threaded insert 4-40).

The RMC33MMST differs from the AMC33MMST in the following parameters: contact material composition (phosphor bronze versus beryllium copper), card thickness specification (0.062" defined versus unspecified), mounting type designation (through hole versus unspecified), connector color (black versus unspecified), product status (active versus obsolete), and regulatory classification (EAR99 versus OBSOLETE). These differences do not affect functional interchangeability within the specified electrical and mechanical operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The RMC33MMST is the appropriate substitute for the obsolete AMC33MMST. The substitute part maintains full compliance with ROHS3 and REACH requirements, matching the regulatory status of the original component. Both connectors operate within identical electrical and mechanical specifications, including contact finish thickness, operating temperature range, and insulation material properties.

The RMC33MMST is currently in active production status with confirmed inventory availability (828 pieces), whereas the AMC33MMST is obsolete. Selection of the RMC33MMST ensures long-term component availability for production and field service requirements. The active product status of the RMC33MMST provides access to ongoing manufacturer support and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Are the AMC33MMST and RMC33MMST mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 66-position configuration, 0.100" pitch, dual read-out, flush mount flange with threaded 4-40 insert, and PPS insulation material. Physical mounting and board interface dimensions are equivalent.

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

A: The AMC33MMST uses beryllium copper contacts, while the RMC33MMST uses phosphor bronze contacts. Both materials are gold-plated to 30.0µin thickness and operate across the same temperature range (-65°C to 200°C). Contact material selection does not affect electrical performance within the specified operating envelope.

Q: Does the RMC33MMST specify a card thickness while the AMC33MMST does not?

A: The RMC33MMST specifies 0.062" (1.57mm) card thickness. This specification defines the mechanical tolerance for the female edgecard interface. The absence of this specification in the AMC33MMST documentation does not indicate incompatibility; rather, it reflects different documentation practices between product generations.

Q: Are both connectors RoHS3 compliant?

A: Yes. Both the AMC33MMST and RMC33MMST are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the AMC33MMST classified as obsolete?

A: The AMC33MMST is classified as obsolete due to product lifecycle discontinuation. The RMC33MMST represents the active equivalent in the Sullins Connector Solutions product line, providing equivalent functionality with ongoing manufacturer support and supply availability.

Q: What is the significance of the black color designation on the RMC33MMST?

A: The black color is a cosmetic specification that does not affect electrical or mechanical performance. Color designation reflects manufacturing and identification practices for the active product variant.

Q: Can the RMC33MMST be used in applications originally designed for the AMC33MMST?

A: Yes. The RMC33MMST is functionally equivalent across all critical electrical and mechanical parameters. Direct substitution is appropriate for new production and field service applications.
