WR11AT/V Rocker Switch SPST 15A 125V - Equivalent & Substitute Parts

Part Overview

The WR11AT/V is a panel-mount rocker switch manufactured by NKK Switches, designed for SPST (Single Pole Single Throw) on-off applications at 15A AC/DC and 125V AC rating. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and termination specifications to ensure direct compatibility in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR11AT/V is determined by strict equivalence across the following critical parameters:

• Circuit and Function: SPST on-off configuration only
• Electrical Ratings: 15A AC/DC current capacity and 125V AC / 30V DC voltage ratings
• Mechanical Interface: Panel mount snap-in mounting with rectangular cutout dimensions of 34.20mm x 17.20mm
• Actuator Specification: Concave (curved) black actuator without marking
• Termination: Screw terminal connection
• Environmental Protection: IP67 ingress protection rating
• Operating Conditions: -25°C to 85°C temperature range
• Regulatory Compliance: EN and UL approvals

Only parts matching all these parameters qualify as direct substitutes. Deviations in any parameter render a part incompatible for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The WR11AT (without the /V suffix) is the direct functional equivalent to the WR11AT/V. Both parts are manufactured by NKK Switches and share identical electrical ratings, mechanical dimensions, and environmental specifications. The primary distinction is product status: the WR11AT/V is obsolete, while the WR11AT is active and currently in production.

The WR11AT substitute carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. Both parts maintain EN and UL approvals, ensuring compliance with international safety standards. The active status of the WR11AT makes it the appropriate selection for new designs, maintenance applications, and component replenishment where the obsolete WR11AT/V is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the WR11AT directly replace the WR11AT/V in existing installations?

A: Yes. The WR11AT is a direct substitute. Both parts share identical electrical ratings (15A AC/DC, 125V AC, 30V DC), mechanical dimensions (34.20mm x 17.20mm panel cutout), mounting configuration (panel mount snap-in), and termination style (screw terminal). No circuit modifications or mechanical adjustments are required.

Q: What is the difference between WR11AT/V and WR11AT?

A: The WR11AT/V is an obsolete variant, while the WR11AT is the active production equivalent. The /V suffix designation on the obsolete part does not indicate a functional difference. The active WR11AT includes ROHS3 compliance certification, which the obsolete variant does not specify.

Q: Are there packaging differences between these parts?

A: The WR11AT/V was supplied in standard packaging (not specified), while the current WR11AT is available in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same environmental and safety standards?

A: Yes. Both the WR11AT/V and WR11AT carry EN and UL approvals. Both are rated for IP67 ingress protection (dust tight, waterproof) and operate across the identical temperature range of -25°C to 85°C. Both feature epoxy sealed terminals.

Q: What is the mechanical and electrical life expectancy?

A: Both parts are rated for 30,000 mechanical cycles and 15,000 electrical cycles under specified operating conditions.

Q: Is the WR11AT suitable for new designs?

A: Yes. The WR11AT is the active production part and carries current regulatory compliance (ROHS3, REACH unaffected). It is the appropriate choice for new designs and applications requiring SPST 15A 125V rocker switch functionality.
