WR11AF/UCV Equivalent & Substitute Parts

Part Overview

The WR11AF/UCV is a rocker switch manufactured by NKK Switches, designed for panel-mount applications requiring SPST (Single Pole Single Throw) on-off switching functionality. This component is rated for 15A at 125V AC and 30V DC, with IP67 ingress protection suitable for dust-tight and waterproof environments. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WR11AF/UCV is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC, 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Termination style (Quick Connect - 0.250")
• Panel cutout dimensions (Rectangular - 34.20mm x 17.20mm)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications

The WR11AF/CUL meets all these criteria and is classified as a direct substitute. This part maintains identical electrical and mechanical specifications while offering improved product status (Active vs. Obsolete) and enhanced compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The WR11AF/CUL is the direct equivalent substitute for the WR11AF/UCV. Both parts share identical electrical ratings, mechanical specifications, and dimensional requirements. The primary distinction is product status: WR11AF/UCV is obsolete while WR11AF/CUL is active in production.

Selection of WR11AF/CUL is supported by:

• Identical performance across all critical electrical parameters (15A, 125V AC, 30V DC)
• Matching mechanical specifications and panel cutout dimensions
• Equivalent ingress protection and operating temperature range
• Active product status ensuring ongoing availability and supply chain reliability
• Enhanced compliance documentation (ROHS3 Compliant, REACH Unaffected)
• Maintained EN and UL approvals

For applications currently using WR11AF/UCV, direct substitution with WR11AF/CUL requires no circuit modifications or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can WR11AF/CUL be used as a direct replacement for WR11AF/UCV?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The panel cutout dimensions, termination style, and electrical ratings are equivalent, enabling direct substitution without design changes.

Q: What is the difference between WR11AF/UCV and WR11AF/CUL?

A: The primary differences are product status and compliance documentation. WR11AF/UCV is obsolete, while WR11AF/CUL is active. WR11AF/CUL includes ROHS3 compliance and REACH unaffected status documentation.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a rectangular panel cutout of 34.20mm x 17.20mm, enabling mechanical interchangeability in existing panel designs.

Q: Do both parts use the same termination style?

A: Yes. Both parts use Quick Connect - 0.250" (6.3mm) termination, ensuring compatibility with existing wiring harnesses and connectors.

Q: What is the operating temperature range for these switches?

A: Both parts operate across -25°C to 85°C, suitable for industrial and commercial applications within this thermal envelope.

Q: Are there any compliance differences between the two parts?

A: Both parts maintain EN and UL approvals. WR11AF/CUL provides additional documentation confirming ROHS3 compliance and REACH unaffected status.
