AMC53MMST Equivalent & Substitute Parts

Part Overview

The AMC53MMST is a 106-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 procurement availability for new production and field service applications.

Substitute Part Grouping Explanation

Substitution of the obsolete AMC53MMST with the active RMC53MMST is based on electrical and mechanical parameter alignment within the card edge connector category. Both connectors maintain identical specifications for the following critical parameters: 106-position configuration, dual-row layout, 0.100" (2.54mm) pitch, male gender, dual read-out functionality, gold contact finish at 30.0µin thickness, solder termination, -65°C to 200°C operating temperature range, PPS insulation material, flush mount with threaded insert (4-40), ROHS3 compliance, and MSL 1 rating.

The RMC53MMST qualifies as a direct substitute based on these matching electrical and mechanical parameters. Differences in contact material (phosphor bronze versus beryllium copper), card thickness specification (0.062" defined versus unspecified), color designation (black versus unspecified), mounting type classification (through hole versus unspecified), and ECCN/HTSUS coding reflect manufacturing updates and regulatory classification changes that do not affect functional interchangeability within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

The RMC53MMST is the appropriate substitute for the obsolete AMC53MMST based on product status and regulatory compliance alignment. The substitute part maintains active manufacturing status, ensuring long-term procurement availability and supply chain continuity. Both parts satisfy ROHS3 compliance and REACH unaffected classification, supporting regulatory requirements for current production environments.

Selection of the RMC53MMST eliminates obsolescence risk associated with the AMC53MMST while preserving electrical and mechanical compatibility across all critical connector parameters. The active product status of the RMC53MMST provides superior availability for new designs, production builds, and field service applications requiring 106-position male card edge connectors at 0.100" pitch with dual read-out configuration.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC53MMST?

A: The AMC53MMST is classified as obsolete. The RMC53MMST is the active equivalent from the same manufacturer, providing continued access to functionally identical 106-position male card edge connectors.

Q: Are the electrical specifications identical between AMC53MMST and RMC53MMST?

A: Yes. Both connectors share identical electrical specifications including 106 positions, dual-row configuration, 0.100" pitch, gold contact finish at 30.0µin thickness, solder termination, and -65°C to 200°C operating temperature range.

Q: Are the mechanical specifications identical between these connectors?

A: The connectors share identical mechanical specifications for position count, row configuration, pitch, gender, read-out configuration, insulation material (PPS), and flange features (flush mount, top opening, threaded insert 4-40).

Q: What differences exist between the AMC53MMST and RMC53MMST?

A: The RMC53MMST specifies card thickness at 0.062" (1.57mm), uses phosphor bronze contact material instead of beryllium copper, includes black color designation, and is classified as through hole mounting. The AMC53MMST does not specify these parameters. These differences do not affect functional interchangeability.

Q: Are both connectors RoHS compliant?

A: Yes. Both the AMC53MMST and RMC53MMST are ROHS3 compliant and REACH unaffected, supporting current regulatory requirements.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Can the RMC53MMST be used as a direct replacement in existing designs?

A: The RMC53MMST is electrically and mechanically compatible with the AMC53MMST across all specified parameters. Compatibility is determined by the matching 106-position, dual-row, 0.100" pitch configuration and identical contact finish specifications.
