AMC34MMSD Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC34MMSD is a 68-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 with gold-plated beryllium copper contacts and operates across the temperature range of -65°C to 200°C.

The AMC34MMSD is classified as obsolete. Identification of equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and field service requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC34MMSD with the RMC34MMSD is based on alignment of the following critical parameters:

Matching Parameters:

• Connector type: Card edge, male configuration
• Number of positions: 68 total positions
• Pitch specification: 0.100" (2.54mm)
• Read out configuration: Dual
• Contact finish: Gold plating at 30.0µin (0.76µm)
• Operating temperature range: -65°C ~ 200°C
• Insulation material: Polyphenylene Sulfide (PPS)
• Termination method: Solder
• Flange feature: Flush mount, unthreaded, 0.125" (3.18mm) diameter
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Differing Parameters:

• Contact material: Beryllium copper (AMC34MMSD) versus phosphor bronze (RMC34MMSD)
• Flange opening orientation: Side opening (AMC34MMSD) versus top opening (RMC34MMSD)
• Card thickness specification: Not specified (AMC34MMSD) versus 0.062" (1.57mm) (RMC34MMSD)
• Mounting type: Not specified (AMC34MMSD) versus through hole (RMC34MMSD)
• Color: Not specified (AMC34MMSD) versus black (RMC34MMSD)
• Product status: Obsolete (AMC34MMSD) versus active (RMC34MMSD)

The RMC34MMSD maintains functional equivalence through identical electrical and mechanical interface specifications while offering active product status and current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The RMC34MMSD serves as the direct substitute for the obsolete AMC34MMSD based on the following engineering criteria:

Compliance and Regulatory Status: Both connectors maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. The RMC34MMSD carries active product status with current manufacturing support from Sullins Connector Solutions.

Electrical Interface Compatibility: Identical pitch (0.100"), position count (68), and dual read-out configuration ensure direct electrical interface compatibility with existing female edgecard receptacles designed for the AMC34MMSD.

Thermal and Environmental Performance: Both connectors operate across the identical temperature range (-65°C to 200°C) and maintain MSL 1 rating, supporting equivalent environmental performance in target applications.

Physical Interface Considerations: The primary physical difference involves flange opening orientation (side opening versus top opening) and card thickness specification. System designers must verify that the top-opening configuration of the RMC34MMSD accommodates existing mechanical mounting and card insertion pathways. The specified card thickness of 0.062" (1.57mm) for the RMC34MMSD should be confirmed against actual edgecard dimensions in the target application.

Contact Material Transition: The shift from beryllium copper to phosphor bronze contacts maintains gold plating specifications and electrical performance while offering manufacturing continuity through an active product line.

Frequently Asked Questions (FAQ)

Q: Can the RMC34MMSD directly replace the AMC34MMSD in existing designs?

A: The RMC34MMSD provides electrical interface compatibility through identical pitch, position count, and read-out configuration. Physical compatibility requires verification of the flange opening orientation (top opening versus side opening) and confirmation that the 0.062" (1.57mm) card thickness specification matches the edgecards in the target application.

Q: What is the significance of the contact material change from beryllium copper to phosphor bronze?

A: Both materials provide equivalent electrical performance when combined with identical gold plating specifications (30.0µin thickness). The contact material change reflects manufacturing process updates while maintaining functional equivalence for the connector interface.

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

A: Both connectors maintain identical RoHS3 compliance and REACH unaffected status. No regulatory differences exist between the two parts.

Q: Why is the AMC34MMSD classified as obsolete?

A: The AMC34MMSD has been superseded by the RMC34MMSD in the Sullins Connector Solutions product line. The RMC34MMSD offers active manufacturing status and current supply chain support.

Q: What should be verified before implementing the RMC34MMSD as a substitute?

A: Verification should confirm that the top-opening flange configuration accommodates existing mechanical mounting and card insertion pathways. The specified card thickness of 0.062" (1.57mm) should be validated against actual edgecard dimensions in the target application.

Q: Do both connectors support the same operating temperature range?

A: Yes. Both the AMC34MMSD and RMC34MMSD operate across the identical temperature range of -65°C to 200°C.

Q: Is the moisture sensitivity level the same for both connectors?

A: Yes. Both connectors maintain MSL 1 (Unlimited) rating, indicating equivalent moisture sensitivity performance.
