AMC49MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC49MMSD is a 58-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 AMC49MMSD is classified as obsolete, necessitating identification of active substitute components that maintain functional compatibility with existing female edgecard designs while meeting current procurement and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC49MMSD is determined by the following critical parameters that must align between the main part and substitute components:

Mandatory Compatibility Parameters:

• Gender: Male
• Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Read Out: Dual
• Termination: Solder
• Card Type: Fits Female Edgecards
• Insulation Material: Polyphenylene Sulfide (PPS)
• Operating Temperature Range: -65°C ~ 200°C
• Contact Finish: Gold
• RoHS Compliance: ROHS3 Compliant

The RMC49MMSD qualifies as a direct substitute based on alignment across all mandatory compatibility parameters. While the RMC49MMSD features a higher position count (98 positions versus 58 positions) and differs in contact material composition and flange opening orientation, these variations do not preclude substitution when the application accommodates the increased position density and the female edgecard interface supports the connector's mechanical and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The RMC49MMSD is the appropriate substitute for the obsolete AMC49MMSD based on the following engineering criteria:

Product Status: The RMC49MMSD maintains active product status with current manufacturing availability, whereas the AMC49MMSD is obsolete. This transition ensures long-term supply chain continuity and access to current manufacturing quality standards.

Compliance Certifications: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions. The RMC49MMSD carries ECCN classification EAR99 and HTSUS code 8536.69.4040, providing clear export control and tariff classification for procurement purposes.

Electrical and Mechanical Compatibility: The RMC49MMSD preserves the critical interface parameters of the AMC49MMSD, including pitch, row configuration, read-out architecture, and operating temperature range. The connector accommodates female edgecards with identical electrical and mechanical engagement characteristics.

Moisture Sensitivity: Both components carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly operations.

Selection of the RMC49MMSD for replacement applications is supported by active product status, full regulatory compliance, and functional parameter alignment with the obsolete AMC49MMSD.

Frequently Asked Questions (FAQ)

Q: Can the RMC49MMSD directly replace the AMC49MMSD in existing designs?

A: The RMC49MMSD functions as a direct substitute when the application accommodates the increased position count (98 versus 58 positions). The connector maintains identical pitch, row configuration, and dual read-out architecture. Verification that the female edgecard interface supports the RMC49MMSD's mechanical envelope and position density is required.

Q: What is the primary difference between the AMC49MMSD and RMC49MMSD?

A: The RMC49MMSD provides 98 positions compared to the AMC49MMSD's 58 positions, both at 0.100" pitch. The RMC49MMSD uses phosphor bronze contacts versus beryllium copper in the AMC49MMSD. The RMC49MMSD features top opening flange orientation, while the AMC49MMSD uses side opening orientation. Both maintain identical operating temperature range, gold contact finish, and PPS insulation material.

Q: Are there compliance or regulatory differences between these connectors?

A: Both connectors maintain ROHS3 compliance and REACH unaffected status. The RMC49MMSD carries explicit ECCN (EAR99) and HTSUS (8536.69.4040) classifications, providing clear export control and tariff documentation. The AMC49MMSD is marked as OBSOLETE in ECCN classification.

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

A: Both the AMC49MMSD and RMC49MMSD carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Does the contact material difference affect electrical performance?

A: Both beryllium copper (AMC49MMSD) and phosphor bronze (RMC49MMSD) contacts are gold-plated with identical finish thickness (30.0µin / 0.76µm). The contact materials provide equivalent electrical conductivity and contact resistance characteristics for card edge connector applications.

Q: What mounting considerations apply to the RMC49MMSD?

A: The RMC49MMSD is specified for through-hole mounting with solder termination, identical to the AMC49MMSD. The connector features flush mount configuration with unthreaded 0.125" (3.18mm) diameter flange. The primary mechanical difference is the top opening flange orientation versus the AMC49MMSD's side opening configuration.
