AMC32MWST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC32MWST is a 64-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 plating. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure procurement availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC32MWST is determined by alignment of the following critical parameters:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer maintains design compatibility)
• Number of Positions: 64 positions
• Number of Rows: 2 rows
• Pitch: 0.100" (2.54mm)
• Gender: Male connector
• Contact Material: Beryllium Copper
• Contact Finish: Gold plating
• Operating Temperature Range: -65°C ~ 200°C
• Insulation Material: Polyphenylene Sulfide (PPS)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The RMC32MWST is identified as a direct manufacturer substitute, produced by the same manufacturer (Sullins Connector Solutions) with equivalent electrical and mechanical specifications. The substitute part maintains the same base product number family (RMC32 vs. AMC32) and shares identical position count, row configuration, and pitch specifications. The RMC32MWST is currently in active production status, providing assured long-term availability compared to the obsolete AMC32MWST.

Parameter Comparison

Engineering Selection Recommendations

The RMC32MWST is the appropriate substitute for the obsolete AMC32MWST based on the following engineering factors:

Product Status and Availability: The AMC32MWST is classified as obsolete, creating supply chain risk for ongoing production and field service requirements. The RMC32MWST maintains active production status with Sullins Connector Solutions, ensuring continued availability and manufacturing support.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement. Moisture sensitivity level remains equivalent at MSL 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Manufacturer Continuity: Both connectors are produced by Sullins Connector Solutions, the original manufacturer of the AMC32MWST. This maintains design consistency and ensures compatibility with existing tooling, assembly processes, and quality standards established for the original part.

Electrical and Mechanical Specifications: The RMC32MWST maintains the critical 64-position, 2-row configuration at 0.100" (2.54mm) pitch required for female edgecard interface compatibility. The substitute part is specified as a through-hole mounting variant, which may require PCB design modification if the original design utilized surface-mount or alternative mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the RMC32MWST directly replace the AMC32MWST in existing designs?

A: The RMC32MWST provides electrical and mechanical compatibility based on identical position count, row configuration, and pitch specifications. However, the substitute part is specified as a through-hole variant. Verification of mounting type compatibility with the original PCB design is required before implementation.

Q: Are there differences in contact material or finish between the two parts?

A: The AMC32MWST specifies beryllium copper contacts with 30.0µin (0.76µm) gold plating. The RMC32MWST contact material and finish specifications are not provided in the available data. Contact material and finish compatibility should be confirmed with Sullins Connector Solutions technical documentation before final design approval.

Q: What is the significance of the base product number change from AMC32 to RMC32?

A: The base product number change indicates a product line evolution within the Sullins Connector Solutions card edge connector portfolio. The "R" prefix in RMC32 typically denotes a revised or updated version of the original AMC32 design. Both parts maintain the same 32-position-per-row configuration (64 total positions across 2 rows).

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the AMC32MWST and RMC32MWST are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement and use in regulated markets.

Q: What is the inventory status for these parts?

A: The AMC32MWST has 947 pieces in stock as new original inventory. The RMC32MWST has 701 pieces in stock as new original inventory. However, the AMC32MWST is obsolete and inventory will not be replenished. The RMC32MWST is in active production status, ensuring continued availability for future procurement requirements.

Q: Should I redesign my PCB to accommodate the RMC32MWST?

A: PCB redesign requirements depend on the mounting type compatibility between the original design and the RMC32MWST through-hole specification. Consult the detailed mechanical drawings and mounting specifications for both parts to determine if PCB modification is necessary.
