WR12AL/UCV Rocker Switch SPDT 15A 125V - Equivalent & Substitute Parts

Part Overview

The WR12AL/UCV is a panel-mount rocker switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry rated for 15A at 125V AC and 30V DC. This component is classified as obsolete, making identification of compatible substitutes essential for ongoing system maintenance and new design implementations. The switch provides IP67 ingress protection with a concave black actuator and wire lead termination suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR12AL/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 (Wire Leads)
• Ingress protection rating (IP67)
• Panel cutout dimensions (34.20mm x 17.20mm)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications

The WR12AL/CUL meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: WR12AL/CUL is active production, whereas WR12AL/UCV is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The WR12AL/CUL is the direct equivalent for the obsolete WR12AL/UCV. Both components share identical electrical and mechanical specifications, including current and voltage ratings, circuit configuration, mounting dimensions, and environmental protection ratings. The WR12AL/CUL maintains active production status and carries ROHS3 compliance and REACH unaffected designation, making it suitable for new designs and replacement applications where regulatory compliance is required.

Frequently Asked Questions (FAQ)
