Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR12AF/UCV is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC / 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Actuator type and color (Concave, Black)
• Termination style (Quick Connect - 0.250")
• Panel cutout dimensions (Rectangular - 34.20mm x 17.20mm)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C ~ 85°C)
• Mechanical and electrical life specifications
• Approval agencies (EN, UL)

The substitute part WR12AF/CUL meets all these criteria, with the distinction that it carries Active product status and includes RoHS3 compliance and REACH unaffected designation.
