WR12ASN/V Rocker Switch SPDT 15A 125V - Equivalent & Substitute Parts

Part Overview

The WR12ASN/V is a panel-mount rocker switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a 15A AC/DC current rating at 125V AC / 30V DC. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and component procurement.

The WR12ASN represents the direct active equivalent, maintaining identical electrical and mechanical specifications while offering improved availability and current product status support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR12ASN/V is determined by strict equivalence across the following critical parameters:

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

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

Environmental Parameters: Ingress protection rating (IP67), operating temperature range (-25°C to 85°C), mechanical life (30,000 cycles), and electrical life (15,000 cycles) must be maintained.

The WR12ASN qualifies as a direct substitute based on complete parameter alignment across all electrical, mechanical, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The WR12ASN is the appropriate selection for applications currently using the WR12ASN/V. Both components maintain identical electrical performance and mechanical compatibility, with the WR12ASN offering the advantage of active product status and current manufacturing support.

The WR12ASN provides ROHS3 compliance and REACH unaffected status, meeting contemporary regulatory requirements. Both components carry EN and UL approvals, ensuring compliance with international safety standards.

For new designs or component replacement in existing systems, the WR12ASN should be specified to ensure long-term availability and compliance with current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can WR12ASN be used as a direct replacement for WR12ASN/V?

A: Yes. The WR12ASN provides complete electrical and mechanical equivalence. All critical parameters including circuit configuration, current and voltage ratings, mounting dimensions, and environmental specifications are identical.

Q: Are there differences in compliance or regulatory status?

A: The WR12ASN includes ROHS3 compliance and REACH unaffected status, whereas the WR12ASN/V does not specify these certifications. Both components maintain EN and UL approvals.

Q: Will the WR12ASN fit existing panel cutouts designed for WR12ASN/V?

A: Yes. Both components share identical panel cutout dimensions of 34.20mm x 17.20mm rectangular format and use the same snap-in mounting method.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both components are rated for 15A AC/DC at 125V AC / 30V DC with SPDT On-On switching function.

Q: What is the difference in packaging between these parts?

A: The WR12ASN/V is packaged in standard format, while the WR12ASN is supplied in bulk packaging. This does not affect component performance or compatibility.
