Engineering Selection Recommendations
The WR12BT is a direct equivalent substitute for the obsolete WR12BT/V. Both parts are manufactured by NKK Switches and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: WR12BT/V is obsolete while WR12BT maintains active status with current manufacturing support.
The WR12BT substitute offers additional compliance advantages. It carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements. The substitute part is available in bulk packaging with 837 units in current inventory, providing supply chain continuity for applications requiring SPDT 15A 125V rocker switches with panel-mount snap-in configuration.
Selection of WR12BT over the obsolete WR12BT/V is supported by maintained electrical performance, identical mechanical interface, active product status, and enhanced regulatory compliance documentation.
Frequently Asked Questions (FAQ)
Q: Can WR12BT be used as a direct replacement for WR12BT/V?
A: Yes. Both parts are manufactured by NKK Switches and meet identical specifications for circuit configuration (SPDT), current rating (15A AC/DC), voltage rating (125V AC, 30V DC), mounting type (panel mount snap-in), actuator type (concave ivory), termination style (screw terminal), ingress protection (IP67), and panel cutout dimensions (34.20mm x 17.20mm). No design modification is required.
Q: What is the primary reason to transition from WR12BT/V to WR12BT?
A: The WR12BT/V is classified as obsolete product status. The WR12BT maintains active manufacturing status with current inventory availability and enhanced regulatory compliance (ROHS3 compliant, REACH unaffected). This ensures long-term supply chain support and compliance with current environmental standards.
Q: Are there packaging differences between WR12BT/V and WR12BT?
A: Yes. WR12BT/V is supplied in standard packaging, while WR12BT is available in bulk packaging. Both configurations contain the identical component with no functional or mechanical differences.
Q: Do both parts meet the same approval standards?
A: Yes. Both WR12BT/V and WR12BT carry EN and UL approval agency certifications. The WR12BT substitute additionally documents ROHS3 compliance and REACH unaffected status.
Q: What are the mechanical and electrical life specifications?
A: Both parts are rated for 30,000 mechanical cycles and 15,000 electrical cycles, with operating temperature range of -25°C to 85°C. These specifications are identical between the main part and substitute.
