Key Parameters

Substitute Part Grouping Explanation

Substitution for the WR12AS/V is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT (Single Pole Double Throw)
• Switch Function: On-On operation
• Current Rating: 15A (AC/DC)
• Voltage Rating: 125V AC / 30V DC minimum
• Mounting Type: Panel Mount, Snap-In
• Panel Cutout Dimensions: Rectangular - 34.20mm x 17.20mm
• Termination Style: Solder Lug
• Ingress Protection: IP67 minimum
• Operating Temperature Range: -25°C to 85°C
• Mechanical Life: 30,000 Cycles minimum
• Electrical Life: 15,000 Cycles minimum

The WR12AS (without the /V suffix variant designation) from NKK Switches meets all specified parameters and serves as a direct equivalent. This part maintains identical electrical ratings, mechanical specifications, and physical dimensions while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The WR12AS serves as the direct substitute for the obsolete WR12AS/V. Both parts are manufactured by NKK Switches and maintain identical electrical and mechanical specifications. The WR12AS offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The WR12AS carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Both parts hold EN and UL approvals, confirming suitability for applications requiring recognized safety certifications.

For applications where the WR12AS/V is currently deployed, direct replacement with WR12AS is electrically and mechanically compatible without circuit modification or panel redesign. The identical panel cutout dimensions (34.20mm x 17.20mm) and snap-in mounting mechanism ensure drop-in compatibility.

Frequently Asked Questions (FAQ)

Q: Can WR12AS directly replace WR12AS/V without modification?

A: Yes. The WR12AS is electrically and mechanically equivalent to the WR12AS/V. Both parts share identical SPDT circuit configuration, 15A/125V AC ratings, panel cutout dimensions, and mounting specifications. No circuit or panel modifications are required.

Q: What is the difference between WR12AS/V and WR12AS?

A: The primary difference is product status. WR12AS/V is obsolete, while WR12AS is active. The WR12AS also carries ROHS3 compliance and REACH unaffected certification. All electrical and mechanical parameters remain identical.

Q: Are the panel cutout dimensions identical?

A: Yes. Both WR12AS/V and WR12AS require a rectangular panel cutout of 34.20mm x 17.20mm. Existing panel designs require no modification for substitution.

Q: What certifications apply to the substitute part?

A: The WR12AS holds EN and UL approvals, matching the WR12AS/V. Additionally, the WR12AS is ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Is the solder lug termination identical?

A: Yes. Both parts use solder lug termination, ensuring compatibility with existing PCB layouts and wiring harnesses.

Q: What is the operating temperature range?

A: Both WR12AS/V and WR12AS operate across -25°C to 85°C, suitable for industrial and commercial applications.
