WR11AL/UCV Equivalent & Substitute Parts

Part Overview

The WR11AL/UCV is a rocker switch manufactured by NKK Switches, designed for panel-mount applications requiring SPST (Single Pole Single Throw) on-off switching. 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 compatible substitutes essential for ongoing maintenance and repair applications where this switch type is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR11AL/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 and panel cutout dimensions (Panel Mount, Snap-In; Rectangular 34.20mm x 17.20mm)
• Actuator type and color (Concave, Black)
• Termination style (Wire Leads)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications (30,000 and 15,000 cycles respectively)
• Regulatory approvals (EN, UL)

The WR11AL/CUL meets all these criteria and is classified as a direct manufacturer substitute. The primary distinction is product status: WR11AL/UCV is obsolete, while WR11AL/CUL is active, and packaging differs (bulk versus original packaging).

Parameter Comparison

Engineering Selection Recommendations

The WR11AL/CUL is the direct equivalent substitute for the WR11AL/UCV. Both components share identical electrical and mechanical specifications, including current and voltage ratings, circuit configuration, mounting dimensions, and environmental protection ratings. The WR11AL/CUL is the preferred selection due to its active product status, ensuring ongoing availability and support. Additionally, the WR11AL/CUL carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and procurement.

For applications where the WR11AL/UCV is currently specified, direct replacement with WR11AL/CUL is functionally and mechanically compatible without design modification.

Frequently Asked Questions (FAQ)

Q: Can WR11AL/CUL be used as a direct replacement for WR11AL/UCV?

A: Yes. Both parts are identical in electrical performance, mechanical dimensions, and environmental ratings. The WR11AL/CUL is the active production equivalent.

Q: What is the difference between WR11AL/UCV and WR11AL/CUL?
