Substitute Part Grouping Explanation

Substitution of the ASD2K22N-111 is based on electrical and mechanical compatibility within the IDEC keylock switch product family. The substitute part ASD2K22NU-111 maintains compatibility through the following critical parameters:

• Circuit Configuration: Both parts support 4PST-2NO/2NC contact arrangement
• Current and Voltage Ratings: Electrical specifications remain within the same operational envelope (10A AC / 110V, 8A DC / 24V)
• Actuator Type: Flat key actuator design is preserved
• Mounting Interface: Panel mount configuration with identical cutout dimensions (30.50mm circular)
• Termination: Screw terminal connections are maintained
• Regulatory Compliance: Both parts are ROHS3 compliant with MSL 1 rating

The ASD2K22NU-111 represents an active production alternative within the IDEC component portfolio, providing functional equivalence for the obsolete ASD2K22N-111.
