WR12AFN/V Rocker Switch SPDT 15A 125V - Equivalent & Substitute Parts

Part Overview

The WR12AFN/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 maintenance and new design implementations. The WR12AFN represents the direct active equivalent, maintaining identical electrical and mechanical specifications while offering current availability and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR12AFN/V is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC / 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Actuator type and color (Concave, Black)
• Termination style (Quick Connect - 0.250")
• Panel cutout dimensions (Rectangular - 34.20mm x 17.20mm)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications (30,000 / 15,000 cycles)
• Approval certifications (EN, UL)

The WR12AFN qualifies as a direct substitute, maintaining complete parameter alignment with the obsolete WR12AFN/V while offering active product status and enhanced compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The WR12AFN is the appropriate selection for applications currently using or requiring the WR12AFN/V specification. As an active product from the same manufacturer and series, it provides:

• Complete electrical and mechanical parameter equivalence
• Identical panel mounting footprint and snap-in installation method
• Maintained EN and UL approval certifications
• Enhanced compliance status with ROHS3 and REACH documentation
• Current manufacturing and supply chain availability

The transition from WR12AFN/V to WR12AFN requires no circuit redesign, panel modifications, or functional requalification. Both components are interchangeable at the system level.

Frequently Asked Questions (FAQ)

Q: Can WR12AFN be used as a direct replacement for WR12AFN/V in existing assemblies?

A: Yes. The WR12AFN maintains identical electrical ratings (15A at 125V AC / 30V DC), circuit configuration (SPDT On-On), mechanical mounting specifications (Panel Mount, Snap-In with 34.20mm x 17.20mm cutout), and termination style (Quick Connect 0.250"). No circuit modifications or panel rework are required.

Q: What is the difference between WR12AFN/V and WR12AFN?

A: The primary difference is product status. WR12AFN/V is obsolete, while WR12AFN is active. The WR12AFN also includes documented ROHS3 compliance and REACH status, whereas the WR12AFN/V does not specify these certifications. All functional and mechanical parameters are identical.

Q: Are there packaging differences between these parts?

A: The WR12AFN/V packaging is listed as "-" (unspecified), while WR12AFN is supplied in Bulk packaging. This reflects current availability and supply chain practices but does not affect component functionality or compatibility.

Q: Does the WR12AFN meet the same environmental specifications as WR12AFN/V?

A: Yes. Both components operate across the same temperature range (-25°C to 85°C), maintain IP67 ingress protection (dust tight, waterproof), feature epoxy sealed terminals, and are rated for 30,000 mechanical cycles and 15,000 electrical cycles.

Q: What certifications apply to the WR12AFN?

A: The WR12AFN carries EN and UL approvals, matching the WR12AFN/V. Additionally, it is ROHS3 compliant and REACH unaffected, providing enhanced regulatory documentation for modern applications.
