Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD2K20N-RL is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPST-NO)
• Number of positions (2)
• Switch function (Off-On)
• 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 Dia)
• Depth behind flange (53.00mm)
• Operating temperature range (-25°C to 50°C)
• RoHS compliance status

The substitute part ASD2K20NU-RL is identified as a direct equivalent within the IDEC product family, maintaining functional and mechanical compatibility with the obsolete ASD2K20N-RL.

Parameter Comparison

Engineering Selection Recommendations

The ASD2K20NU-RL is designated as the direct substitute for the obsolete ASD2K20N-RL based on manufacturer documentation. Both components maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.
