AMC53MWST Card Edge Connector Equivalent & Substitute Parts

Part Overview

The AMC53MWST is a 106-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 product is currently classified as obsolete, necessitating identification of active substitute components to maintain design continuity and ensure procurement availability for new applications and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMC53MWST is based on the following critical parameters that define functional equivalence within the card edge connector category:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer maintains design consistency)
• Base Product Number: RMC53 series (direct product line evolution)
• Position Count: 106 positions (electrical interface requirement)
• Pitch: 0.100" (2.54mm) (mechanical compatibility with female edgecards)
• Connector Type: Card edge male connector (functional category)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1 (environmental and regulatory alignment)

The RMC53MWST represents the active production equivalent within the Sullins connector portfolio, offering the same core electrical and mechanical interface specifications while maintaining current manufacturing status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: RMC53MWST

The RMC53MWST is the direct active substitute for the obsolete AMC53MWST. Both components are manufactured by Sullins Connector Solutions and maintain identical regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1). The RMC53MWST is currently in active production status with confirmed inventory availability (1117 pieces in stock), ensuring reliable procurement for new designs and legacy system replacements.

The transition from the AMC53 series to the RMC53 series represents a standard product line evolution within the manufacturer's portfolio. Both components share the same fundamental card edge connector architecture and are designed for identical 0.100" (2.54mm) pitch edgecard interfaces.

Compliance Status:

Both the main part and substitute maintain equivalent environmental and regulatory standing:

• ROHS3 Compliant: Confirms restriction of hazardous substances compliance
• REACH Unaffected: Indicates no REACH substance of concern restrictions
• MSL 1 (Unlimited): Specifies unlimited moisture sensitivity level, eliminating moisture-related handling constraints

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the AMC53MWST?

A: The AMC53MWST is classified as obsolete. The RMC53MWST provides an active production alternative from the same manufacturer with equivalent electrical and mechanical specifications.

Q: Are the AMC53MWST and RMC53MWST mechanically compatible with the same female edgecards?

A: Both connectors are 106-position male card edge connectors with 0.100" (2.54mm) pitch designed for female edgecard interfaces. Mechanical compatibility is maintained across the product line transition.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the AMC53MWST and RMC53MWST are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) classification, ensuring equivalent environmental and regulatory standing.

Q: What is the difference between the AMC53 and RMC53 base product numbers?

A: The base product number change from AMC53 to RMC53 reflects the manufacturer's product line evolution. The RMC53 series represents the current active production generation while maintaining functional equivalence with the legacy AMC53 series.

Q: Is the RMC53MWST currently available for procurement?

A: Yes. The RMC53MWST is in active production status with 1117 pieces confirmed in stock, ensuring immediate availability for component selection and procurement.

Q: Can the RMC53MWST be used as a direct replacement in existing designs originally specified for the AMC53MWST?

A: The RMC53MWST maintains the same electrical interface (106 positions, 0.100" pitch, male gender) and mechanical form factor (card edge connector) as the AMC53MWST. Compatibility is determined by the specific application's mechanical mounting and electrical interface requirements.

Q: What is the operating temperature range for the substitute part?

A: The operating temperature range for the AMC53MWST is specified as -65°C ~ 200°C. Equivalent temperature specifications for the RMC53MWST should be confirmed through the manufacturer's current technical documentation.
