Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD3K22N is based on strict electrical and mechanical compatibility within the IDEC keylock switch product family. The critical parameters determining substitutability are:

• Circuit configuration (4PST-2NO/2NC)
• Number of positions (3)
• Current ratings (10A AC / 8A DC minimum)
• Voltage ratings (110V AC / 24V DC minimum)
• Actuator type (Flat Key)
• Contact material (Silver)
• Mounting type (Panel Mount)
• Termination style (Screw Terminal)
• Panel cutout dimensions (Circular 30.50mm)
• Depth behind flange (76.00mm)
• Operating temperature range (-25°C to 50°C)
• Mechanical life (500,000 cycles minimum)
• RoHS compliance (ROHS3)

The ASD3K22NU is identified as a direct substitute based on its membership in the IDEC ASD3 base product family and active product status, indicating continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The ASD3K22NU is the appropriate substitute for the obsolete ASD3K22N. Both components share identical RoHS3 compliance and MSL ratings, ensuring regulatory and environmental compatibility. The ASD3K22NU maintains active product status with IDEC, providing assured availability and continued manufacturer support. Selection of the ASD3K22NU eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing system designs.
