AMC59MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC59MMSD is a 118-position male card edge connector manufactured by Sullins Connector Solutions, designed to interface with female edgecards using a 0.100" (2.54mm) pitch. This connector features dual read-out configuration, gold-plated beryllium copper contacts, and operates across a temperature range of -65°C to 200°C. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Substitute Part Grouping Explanation

The RMC59MMSD qualifies as a direct substitute for the AMC59MMSD based on alignment across critical electrical and mechanical parameters. Both connectors maintain identical position counts (118 total, 59 per row), dual read-out configuration, 0.100" pitch spacing, male gender, solder termination, gold contact finish at 30.0µin thickness, and operating temperature range of -65°C to 200°C. Both utilize Polyphenylene Sulfide insulation material and comply with ROHS3 and REACH requirements.

The substitution is valid under the following conditions: the application accommodates the specified card thickness of 0.062" (1.57mm) for the RMC59MMSD, the through-hole mounting type is compatible with the PCB design, and the contact material transition from beryllium copper to phosphor bronze does not conflict with application-specific electrical requirements. The black color designation of the RMC59MMSD represents a cosmetic difference with no functional impact on connector performance.

Parameter Comparison

Engineering Selection Recommendations

The RMC59MMSD is the appropriate selection for applications currently specified with the AMC59MMSD. The substitute part maintains active product status with Sullins Connector Solutions, ensuring ongoing availability and manufacturing support. Both parts satisfy ROHS3 compliance and REACH requirements, supporting regulatory obligations in current production environments.

The transition from the obsolete AMC59MMSD to the active RMC59MMSD does not introduce compliance risk. The connector maintains identical electrical specifications including position count, pitch, termination method, contact finish thickness, and operating temperature range. The specified card thickness of 0.062" (1.57mm) for the RMC59MMSD must be confirmed as compatible with the target application. The contact material change from beryllium copper to phosphor bronze does not affect compliance status and both materials provide equivalent performance in standard card edge connector applications.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC59MMSD?

A: The AMC59MMSD is classified as obsolete. The RMC59MMSD is the active equivalent from the same manufacturer, ensuring continued availability and manufacturing support for new designs and production continuity.

Q: Are the electrical specifications identical between the two connectors?

A: Yes. Both connectors maintain 118 positions at 0.100" pitch, dual read-out configuration, gold contact finish at 30.0µin thickness, solder termination, and -65°C to 200°C operating temperature range.

Q: What is the difference in contact material, and does it affect compatibility?

A: The AMC59MMSD uses beryllium copper contacts while the RMC59MMSD uses phosphor bronze contacts. Both materials are standard for card edge connectors and provide equivalent electrical and mechanical performance in this application category.

Q: Does the RMC59MMSD specify a card thickness requirement?

A: Yes. The RMC59MMSD is specified for 0.062" (1.57mm) card thickness. This specification must be confirmed as compatible with the target edgecard design.

Q: What is the difference between "Side Opening" and "Top Opening" flange features?

A: The flange opening orientation differs between the two parts. The AMC59MMSD features side opening while the RMC59MMSD features top opening. Both maintain the same 0.125" (3.18mm) diameter unthreaded flush mount configuration. The opening orientation must be confirmed as compatible with the mechanical assembly design.

Q: Are both connectors RoHS3 compliant?

A: Yes. Both the AMC59MMSD and RMC59MMSD 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 RMC59MMSD be used as a direct replacement in existing designs?

A: The RMC59MMSD is electrically and mechanically compatible with the AMC59MMSD for applications using 0.062" (1.57mm) card thickness and accommodating the top opening flange orientation. Mechanical fit and mounting configuration must be confirmed for the specific application.
