Substitute Part Grouping Explanation

Substitution of the ASD3K22N-310-RC is determined by strict equivalence across the following critical parameters:

• Manufacturer: IDEC (same manufacturer ensures design compatibility)
• Circuit Configuration: 4PST-2NO/2NC (contact arrangement must match exactly)
• Number of Positions: 3 (functional requirement)
• Current and Voltage Ratings: 10A AC / 110V and 8A DC / 24V (electrical load capacity)
• Mounting and Termination: Panel mount with screw terminals (mechanical fit and installation method)
• Panel Cutout Dimensions: Circular 30.50mm diameter (physical installation compatibility)
• Actuator Type: Flat key (operational interface)

The substitute part ASD3K22NU-310-RC maintains equivalence across all critical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The ASD3K22NU-310-RC is a direct functional equivalent to the ASD3K22N-310-RC. Both components maintain identical electrical specifications, mechanical dimensions, and contact configurations. The primary distinction is product status: the original part is obsolete while the substitute remains in active production.

Selection of ASD3K22NU-310-RC is supported by:

• Identical circuit configuration and contact arrangement
• Equivalent electrical ratings for AC and DC applications
• Matching mechanical specifications and panel mount dimensions
• ROHS3 compliance maintained across both parts
• Active product status ensuring continued availability and supply chain reliability

Frequently Asked Questions (FAQ)

Q: Can ASD3K22NU-310-RC be used as a direct replacement for ASD3K22N-310-RC?

A: Yes. Both components share identical electrical ratings (10A AC / 110V, 8A DC / 24V), circuit configuration (4PST-2NO/2NC), and mechanical specifications including panel cutout dimensions and screw terminal termination.

Q: What is the primary reason for substitution?

A: The ASD3K22N-310-RC is obsolete. The ASD3K22NU-310-RC provides functional equivalence with active product status and current manufacturing availability.

Q: Are the panel mount dimensions identical?

A: Yes. Both parts feature a circular 30.50mm diameter panel cutout and 76.00mm depth behind flange, ensuring mechanical compatibility in existing panel installations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ASD3K22N-310-RC and ASD3K22NU-310-RC are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level).

Q: What is the difference in packaging?

A: The original part has unspecified packaging, while the substitute is supplied in bulk packaging. This does not affect functional or electrical compatibility.

Q: Are the contact materials the same?

A: The main part specifies silver (Ag) contact material. Contact material specifications for the substitute are not provided in the available data; however, electrical equivalence is maintained.
