Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD3K22N-RC is determined by the following critical parameters:

• Circuit configuration (4PST-2NO/2NC)
• Number of positions (3)
• Current and voltage ratings (10A AC / 110V, 8A DC / 24V)
• Actuator type (Flat Key)
• Mounting type (Panel Mount)
• Termination style (Screw Terminal)
• Panel cutout dimensions (Circular - 30.50mm Dia)
• Depth behind flange (76.00mm)

The substitute part ASD3K22NU-RC maintains compatibility with these core electrical and mechanical parameters, enabling direct replacement in applications requiring the ASD3K22N-RC.

Parameter Comparison

Engineering Selection Recommendations

The ASD3K22NU-RC is the designated substitute for the obsolete ASD3K22N-RC. Both components are manufactured by IDEC and maintain ROHS3 compliance with identical moisture sensitivity ratings. The substitute part carries active product status, ensuring continued availability and supply chain reliability. Selection of the ASD3K22NU-RC eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing installations.

Frequently Asked Questions (FAQ)

Q: Can the ASD3K22NU-RC directly replace the ASD3K22N-RC in existing applications?

A: Yes. Both components share identical electrical ratings (10A AC / 110V, 8A DC / 24V), circuit configuration (4PST-2NO/2NC), mechanical dimensions, and mounting specifications. Direct substitution is supported without circuit modification.

Q: What is the primary advantage of using the ASD3K22NU-RC over the obsolete ASD3K22N-RC?

A: The ASD3K22NU-RC maintains active product status with IDEC, ensuring ongoing availability, supply chain support, and compliance with current regulatory standards. The obsolete ASD3K22N-RC faces inventory depletion and potential discontinuation of technical support.

Q: Are there any differences in packaging between these components?

A: The ASD3K22N-RC packaging specification is not provided. The ASD3K22NU-RC is supplied in bulk packaging. Packaging differences do not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ASD3K22N-RC and ASD3K22NU-RC are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting identical environmental and regulatory requirements.

Q: What are the critical parameters for confirming substitution compatibility?

A: Verify that your application requires a 3-position keylock switch with 4PST-2NO/2NC configuration, 10A AC / 110V or 8A DC / 24V ratings, panel mount installation with screw terminals, and a 30.50mm circular panel cutout. Confirmation of these parameters ensures the ASD3K22NU-RC is suitable for your specific application.
