Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR15AS/UCV is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT only
• Current Rating: 15A (AC/DC)
• Voltage Ratings: 125V AC / 30V DC minimum
• Mounting Type: Panel Mount, Snap-In
• Panel Cutout Dimensions: Rectangular - 34.20mm x 17.20mm
• Termination Style: Solder Lug
• Ingress Protection: IP67 minimum
• Operating Temperature Range: -25°C to 85°C minimum
• Mechanical Life: 30,000 Cycles minimum
• Electrical Life: 10,000 Cycles minimum
• Approval Agencies: EN and UL certification required

The WR15AS/CUL meets all substitution criteria as a direct equivalent within the NKK Switches WR series, with identical electrical and mechanical specifications.
