Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete AMC22MWST is based on alignment of the following critical parameters established for card edge connector compatibility:

Primary Substitution Criteria:

• Manufacturer: Sullins Connector Solutions (same manufacturer ensures design compatibility)
• Category: Card Edge Connectors (functional category match)
• Number of Positions: 44 (electrical interface requirement)
• Number of Rows: 2 (physical configuration requirement)
• Pitch: 0.100" (2.54mm) (contact spacing requirement)
• Gender: Male (connector orientation requirement)
• Read Out: Dual (signal access configuration)
• RoHS Status: ROHS3 Compliant (regulatory compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)
• REACH Status: REACH Unaffected (regulatory compliance requirement)

The substitute part RMC22MWST is classified as an active product from the same manufacturer within the same connector category. This part maintains the core electrical and mechanical specifications necessary for functional equivalence in card edge connector applications.

Parameter Comparison

Engineering Selection Recommendations

The RMC22MWST is the active equivalent substitute for the obsolete AMC22MWST. Both connectors are manufactured by Sullins Connector Solutions and maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production and field applications.

The transition from AMC22MWST to RMC22MWST is supported by:

• Active product status of the substitute part, ensuring ongoing availability and supply chain continuity
• Identical manufacturer source, maintaining design and quality standards
• Equivalent regulatory compliance certifications (ROHS3, REACH)
• Matching moisture sensitivity classification for consistent handling and storage protocols
• Same connector category and base product family (Sullins 22-position card edge connector series)

Selection of the RMC22MWST eliminates obsolescence risk while maintaining compatibility with existing card edge connector interface requirements.

Frequently Asked Questions (FAQ)

Q: Why is the AMC22MWST classified as obsolete?

A: The AMC22MWST has been discontinued by Sullins Connector Solutions. The RMC22MWST serves as the active equivalent product within the manufacturer's current product portfolio.

Q: Are the AMC22MWST and RMC22MWST mechanically compatible?

A: Both connectors are 44-position, 2-row card edge connectors manufactured by Sullins Connector Solutions at 0.100" (2.54mm) pitch. Mechanical compatibility is established through the same manufacturer and connector category classification.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the AMC22MWST and RMC22MWST are ROHS3 compliant and REACH unaffected, satisfying current regulatory standards for electronic component procurement.

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

A: Both connectors are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Can the RMC22MWST be used as a direct replacement in existing designs?

A: The RMC22MWST is the active substitute for the obsolete AMC22MWST within the Sullins card edge connector product line. Design verification should confirm compatibility with specific application requirements.

Q: What is the difference between the base product numbers AMC22 and RMC22?

A: The base product numbers indicate different product lines within the Sullins connector portfolio. The RMC22 series represents the current active generation of 22-position card edge connectors, while the AMC22 series is obsolete.

Q: Is inventory availability a consideration for part selection?

A: The RMC22MWST has 799 pieces in stock as new original inventory, providing immediate availability. The obsolete AMC22MWST has limited remaining inventory (654 pieces) and should not be specified for new designs.
