AMC19MMST Equivalent & Substitute Parts

Part Overview

The AMC19MMST 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, gold-plated beryllium copper contacts, and operates across -65°C to 200°C. The AMC19MMST is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC19MMST with the active RMC19MMST is based on electrical and mechanical parameter alignment within the card edge connector category. Both connectors maintain identical specifications for the following critical parameters: 38-position configuration, male gender, 0.100" (2.54mm) pitch, dual read-out, 2-row arrangement, gold contact finish at 30.0µin thickness, -65°C to 200°C operating temperature range, PPS insulation material, solder termination, flush mount with threaded insert (4-40), ROHS3 compliance, and MSL 1 rating.

The RMC19MMST qualifies as a direct substitute based on these matching electrical and mechanical characteristics. Differences in contact material (phosphor bronze versus beryllium copper), color designation (black), card thickness specification (0.062"), and mounting type classification do not preclude functional equivalence within the established parameter set for this connector category.

Parameter Comparison

Engineering Selection Recommendations

The RMC19MMST is the appropriate selection for applications currently specified with the obsolete AMC19MMST. The substitute part maintains full electrical and mechanical compatibility across all critical connector parameters. The RMC19MMST carries active product status, ensuring availability for procurement and ongoing supply chain support. Both components satisfy ROHS3 compliance and REACH requirements, supporting regulatory obligations in current manufacturing environments. The RMC19MMST is available in production quantities (979 pieces in stock) and carries EAR99 export classification with defined HTSUS coding, facilitating standard procurement and logistics processes.

Frequently Asked Questions (FAQ)

Q: Can the RMC19MMST directly replace the AMC19MMST in existing designs?

A: Yes. The RMC19MMST maintains identical electrical and mechanical specifications across all critical parameters including position count, pitch, row configuration, contact finish, operating temperature range, insulation material, and mounting features. Direct substitution is supported.

Q: What is the significance of the contact material difference between the two parts?

A: The AMC19MMST uses beryllium copper contacts while the RMC19MMST uses phosphor bronze contacts. Both materials are standard for card edge connector applications and are compatible with the specified gold finish thickness and operating temperature range. This difference does not affect functional equivalence.

Q: Does the card thickness specification of 0.062" on the RMC19MMST indicate a design change?

A: The card thickness specification on the RMC19MMST represents the connector's rated compatibility with edgecards of that thickness. This parameter does not affect the connector's ability to interface with standard female edgecards at the specified 0.100" pitch. Both connectors fit female edgecards as their primary function.

Q: Are there any compliance or certification differences between these parts?

A: Both the AMC19MMST and RMC19MMST are ROHS3 compliant and REACH unaffected. The RMC19MMST carries EAR99 export classification, which is standard for passive connector components. Both parts maintain MSL 1 (unlimited) moisture sensitivity rating.

Q: Why is the AMC19MMST classified as obsolete?

A: The AMC19MMST has been discontinued by the manufacturer. The RMC19MMST represents the active equivalent product line for this connector configuration, ensuring continued availability and support for new and existing applications.
