WR11AS/UCV Rocker Switch - Equivalent & Substitute Parts

Part Overview

The WR11AS/UCV is a panel-mount rocker switch manufactured by NKK Switches, designed for SPST (Single Pole Single Throw) on-off applications. This component operates at 15A (AC/DC) with a 125V AC / 30V DC rating and features IP67 ingress protection with epoxy sealed terminals. The WR11AS/UCV is classified as obsolete, making identification of equivalent active alternatives essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR11AS/UCV is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration: SPST
• Current rating: 15A (AC/DC)
• Voltage rating: 125V AC / 30V DC minimum
• Switch function: On-Off

Mechanical Compatibility Requirements:

• Mounting type: Panel Mount, Snap-In
• Panel cutout dimensions: Rectangular - 34.20mm x 17.20mm
• Actuator type: Concave (Curved)
• Termination style: Solder Lug

Environmental & Regulatory Requirements:

• Ingress protection: IP67 minimum
• Operating temperature range: -25°C to 85°C minimum
• Approval agencies: EN and UL certification

The WR11AS (base part number, active status) meets all substitution criteria as a direct equivalent to the obsolete WR11AS/UCV variant.

Parameter Comparison

Engineering Selection Recommendations

The WR11AS (active product) is the direct functional equivalent for the obsolete WR11AS/UCV. Both components share identical electrical ratings, mechanical dimensions, and environmental specifications. The active WR11AS variant provides the additional advantage of current product status with documented ROHS3 compliance and REACH unaffected designation, supporting modern regulatory requirements for new designs and production continuity.

Selection of the WR11AS for replacement applications is based on complete parameter equivalence and active manufacturing status, ensuring supply chain continuity and compliance with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the WR11AS directly replace the WR11AS/UCV in existing applications?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including circuit configuration, current/voltage ratings, mounting type, panel cutout dimensions, and ingress protection rating. The WR11AS is the active production equivalent.

Q: What is the difference between WR11AS/UCV and WR11AS?

A: The WR11AS/UCV is an obsolete variant. The WR11AS is the current active product from NKK Switches with identical functional specifications. The active variant includes ROHS3 compliance and REACH unaffected status documentation.

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both components require a rectangular panel cutout of 34.20mm x 17.20mm for snap-in mounting.

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

A: Both the WR11AS/UCV and WR11AS operate across a temperature range of -25°C to 85°C.

Q: Do these switches meet IP67 specifications?

A: Yes. Both components are rated IP67 (dust tight and waterproof) with epoxy sealed terminals.

Q: What certifications apply to these switches?

A: Both components carry EN and UL approvals. The active WR11AS additionally documents ROHS3 compliance and REACH unaffected status.
