Key Parameters

Substitute Part Grouping Explanation

Substitution for the WR12AT/V is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT only
• Switch Function: On-On operation
• Current Rating: 15A (AC/DC) minimum
• Voltage Ratings: 125V AC and 30V DC minimum
• Mounting Type: Panel Mount, Snap-In
• Actuator Type: Concave (Curved)
• Actuator Color: Black
• Termination Style: Screw Terminal
• Ingress Protection: IP67 or equivalent
• Panel Cutout Dimensions: Rectangular - 34.20mm x 17.20mm
• Operating Temperature Range: -25°C to 85°C minimum
• Mechanical Life: 30,000 Cycles minimum
• Electrical Life: 15,000 Cycles minimum

The substitute part WR12AT meets all these criteria and is manufactured by the same supplier (NKK Switches), ensuring full functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The WR12AT (without the /V suffix) is the direct substitute for the obsolete WR12AT/V. Both parts are manufactured by NKK Switches and share identical electrical, mechanical, and dimensional specifications. The substitute part WR12AT is currently in active production status, ensuring long-term availability and supply chain reliability.

The WR12AT substitute carries ROHS3 compliance certification, meeting current environmental and regulatory standards. Both parts maintain EN and UL approvals, confirming suitability for applications requiring these certifications.

For applications currently using the WR12AT/V, direct replacement with WR12AT requires no circuit modifications, panel cutout adjustments, or terminal reconfiguration. The identical panel cutout dimensions (34.20mm x 17.20mm) and screw terminal connections ensure drop-in compatibility.

Frequently Asked Questions (FAQ)

Q: Can WR12AT directly replace WR12AT/V without any modifications?

A: Yes. The WR12AT is a direct equivalent substitute. All electrical ratings (15A at 125V AC / 30V DC), mechanical specifications (30,000 cycle mechanical life, 15,000 cycle electrical life), mounting configuration (Panel Mount, Snap-In), panel cutout dimensions (34.20mm x 17.20mm), and terminal style (Screw Terminal) are identical. No circuit modifications or panel alterations are required.

Q: What is the difference between WR12AT/V and WR12AT?

A: The primary difference is product status and compliance certification. WR12AT/V is obsolete, while WR12AT is in active production. WR12AT carries ROHS3 compliance certification, meeting current environmental standards. The electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The WR12AT/V was supplied with specific packaging (indicated by the dash in the original data), while WR12AT is available in bulk packaging. This difference does not affect the component's electrical or mechanical performance.

Q: What certifications apply to both parts?

A: Both WR12AT/V and WR12AT carry EN and UL approvals. The substitute WR12AT additionally meets ROHS3 compliance requirements.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both parts operate across the identical temperature range of -25°C to 85°C, ensuring compatibility in equivalent thermal environments.

Q: Can I use WR12AT in applications originally designed for WR12AT/V?

A: Yes. The WR12AT meets or exceeds all specifications of the WR12AT/V. The identical SPDT On-On circuit configuration, 15A current rating, 125V AC / 30V DC voltage ratings, IP67 ingress protection, and mechanical life ratings (30,000 cycles) ensure full functional compatibility.
