WR13AS/UCV Equivalent & Substitute Parts

Part Overview

The WR13AS/UCV is a rocker switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-Off-On functionality. This panel-mount, snap-in switch is rated for 15A at 125V AC and 30V DC, featuring a concave black actuator with solder lug termination and IP67 ingress protection. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR13AS/UCV is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-Off-On), current rating (15A AC/DC), voltage ratings (125V AC / 30V DC), and approval agencies (EN, UL).

Mechanical Parameters: Mounting type (Panel Mount, Snap-In), actuator type (Concave), actuator color (Black), termination style (Solder Lug), and panel cutout dimensions (34.20mm x 17.20mm).

Environmental Parameters: Ingress protection rating (IP67), operating temperature range (-25°C to 85°C), mechanical life (30,000 cycles), and electrical life (10,000 cycles).

Manufacturing Parameters: Base product number (WR13AS) and series designation (WR).

Parts meeting all these criteria are classified as direct equivalents and may be substituted without circuit or mechanical redesign.

Parameter Comparison

Engineering Selection Recommendations

The WR13AS/CUL is a direct equivalent substitute for the obsolete WR13AS/UCV. Both parts share identical electrical ratings, mechanical specifications, and environmental performance characteristics. The primary distinction is product status: WR13AS/UCV is obsolete, while WR13AS/CUL is active and currently in production.

For new designs or component replacement in existing systems, WR13AS/CUL is the appropriate selection due to its active status and continued availability. Both parts carry EN and UL approvals, ensuring compliance with applicable regulatory standards. The WR13AS/CUL additionally carries RoHS3 compliance certification, providing enhanced environmental compliance for applications subject to RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can WR13AS/CUL be used as a direct replacement for WR13AS/UCV?

A: Yes. Both parts are electrically and mechanically identical, with matching SPDT circuit configuration, 15A/125V AC ratings, panel cutout dimensions, and IP67 ingress protection. No circuit or mechanical modifications are required.

Q: What is the primary reason to substitute WR13AS/UCV with WR13AS/CUL?

A: WR13AS/UCV is obsolete and no longer manufactured. WR13AS/CUL is the active production equivalent from the same manufacturer and series, ensuring continued component availability and supply chain reliability.

Q: Are there any compliance differences between these parts?

A: Both parts meet EN and UL approval requirements. WR13AS/CUL additionally carries RoHS3 compliance certification, which may be required for applications subject to RoHS directives.

Q: Will the panel cutout dimensions remain the same after substitution?

A: Yes. Both parts require an identical rectangular panel cutout of 34.20mm x 17.20mm. No mechanical redesign of the mounting interface is necessary.

Q: Are the electrical and mechanical life ratings equivalent?

A: Yes. Both parts are rated for 30,000 mechanical cycles and 10,000 electrical cycles, with identical operating temperature ranges of -25°C to 85°C.
