AMC35MWST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC35MWST is a 70-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 beryllium copper contacts finished in gold and operates across a temperature range of -65°C to 200°C. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure procurement availability for new applications and legacy system support.

Substitute Part Grouping Explanation

The RMC35MWST has been identified as a direct substitute for the obsolete AMC35MWST based on the following critical parameters:

Matching Parameters:

• Manufacturer: Sullins Connector Solutions (same manufacturer ensures design compatibility)
• Base Product Number: RMC35 (directly related to AMC35, indicating product line continuity)
• Number of Positions: 70 positions (identical connector capacity)
• Number of Rows: 2 rows (identical configuration)
• Pitch: 0.100" (2.54mm) (identical spacing standard)
• Category: Card Edge Connectors (same functional category)
• RoHS Status: ROHS3 Compliant (equivalent regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (equivalent environmental rating)
• REACH Status: REACH Unaffected (equivalent regulatory status)

The RMC35MWST maintains the same electrical and mechanical interface specifications required for card edge connector applications, with the primary distinction being its active product status and through-hole termination configuration.

Engineering Selection Recommendations

The RMC35MWST is the appropriate substitute for the obsolete AMC35MWST based on the following engineering criteria:

Product Status Alignment: The RMC35MWST maintains active product status with Sullins Connector Solutions, ensuring ongoing availability and manufacturing support. This addresses the obsolescence of the original AMC35MWST and provides long-term procurement reliability.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements. The moisture sensitivity level of 1 (Unlimited) on both parts indicates equivalent handling and storage requirements.

Electrical and Mechanical Compatibility: The identical 70-position, 2-row configuration at 0.100" (2.54mm) pitch ensures direct functional equivalence for card edge connector applications. Both parts are designed for the same interface standard with female edgecards.

Manufacturer Continuity: Selection of the RMC35MWST from the same manufacturer (Sullins Connector Solutions) maintains design consistency and reduces qualification risk in applications previously using the AMC35MWST.

Frequently Asked Questions (FAQ)

Q: Can the RMC35MWST directly replace the AMC35MWST in existing designs?

A: The RMC35MWST provides electrical and mechanical compatibility based on matching position count, row configuration, and pitch specifications. Design verification should confirm that the through-hole termination of the RMC35MWST is compatible with the intended PCB layout and mounting requirements.

Q: What are the key differences between these two connectors?

A: The primary differences are product status (AMC35MWST is obsolete; RMC35MWST is active) and termination type (RMC35MWST is specified as through-hole). Both maintain identical position count, row configuration, pitch, and regulatory compliance status.

Q: Are the contact materials and finishes identical?

A: The provided specifications for the RMC35MWST do not include detailed contact material and finish information. Contact material and finish specifications should be confirmed through the manufacturer's current technical documentation to ensure compatibility with the original beryllium copper with gold finish of the AMC35MWST.

Q: What is the significance of the base product numbers AMC35 and RMC35?

A: The related base product numbers indicate that both connectors belong to the same product family from Sullins Connector Solutions. This relationship supports the substitution logic and suggests design lineage between the two parts.

Q: Are there any inventory considerations for this substitution?

A: The RMC35MWST has 968 pieces in stock as new original inventory, providing immediate availability. The AMC35MWST, though obsolete, has 907 pieces available. Procurement decisions should account for long-term supply chain requirements and the active status of the RMC35MWST.

Q: What compliance certifications apply to both parts?

A: Both the AMC35MWST and RMC35MWST are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components in most jurisdictions.
