Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASD3K02N is determined by strict alignment of the following critical parameters:

• Circuit configuration (DPST-NC)
• Number of positions (3)
• Current ratings (10A AC / 8A DC minimum)
• Voltage ratings (110V AC / 24V DC minimum)
• Actuator type (Flat Key)
• 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)

The substitute part ASD3K02NU meets these criteria and is classified as an active product, providing continuity for applications currently using the obsolete ASD3K02N.

Parameter Comparison

Engineering Selection Recommendations

The ASD3K02NU is designated as the direct substitute for the obsolete ASD3K02N. Both components are manufactured by IDEC and maintain ROHS3 compliance with identical MSL ratings. The ASD3K02NU's active product status ensures ongoing availability and support for replacement applications. Selection of the ASD3K02NU is appropriate for legacy system maintenance where the ASD3K02N is no longer procurable.
