Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR19BL/V is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT only
• Current rating: 15A (AC/DC)
• Voltage ratings: 125V AC and 30V DC minimum
• Mounting type: Panel Mount, Snap-In
• Panel cutout dimensions: Rectangular 34.20mm x 17.20mm
• Actuator type: Concave (Curved)
• Termination style: Wire Leads
• Ingress protection: IP67 minimum
• Operating temperature range: -25°C to 85°C minimum
• Mechanical life: 30,000 cycles minimum
• Electrical life: 10,000 cycles minimum
• Approval agencies: EN and UL certification

The WR19BL (base product number without the /V suffix variant) meets all substitution criteria as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The WR19BL serves as the direct substitute for the obsolete WR19BL/V. Both components are manufactured by NKK Switches and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: WR19BL/V is obsolete while WR19BL is active and currently in production.

The WR19BL offers additional compliance advantage through ROHS3 certification, meeting current environmental and regulatory requirements. For new designs or ongoing production requiring this rocker switch specification, WR19BL is the appropriate selection. For legacy system maintenance where WR19BL/V components are required, WR19BL provides full functional and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Can WR19BL replace WR19BL/V in existing applications?

A: Yes. WR19BL is a direct functional and physical equivalent. Both components share identical circuit configuration (SPDT), current rating (15A AC/DC), voltage ratings (125V AC / 30V DC), panel cutout dimensions (34.20mm x 17.20mm), mounting type (Panel Mount, Snap-In), and all electrical performance specifications. Physical installation and electrical integration are identical.

Q: What is the difference between WR19BL/V and WR19BL?

A: The components are electrically and mechanically identical. The primary difference is product status: WR19BL/V is obsolete, while WR19BL is active. WR19BL additionally carries ROHS3 compliance certification.

Q: Are the panel cutout dimensions identical?

A: Yes. Both WR19BL/V and WR19BL require a rectangular panel cutout of 34.20mm x 17.20mm. No mechanical redesign or panel modification is necessary when substituting between these parts.

Q: Do both parts meet the same approval standards?

A: Yes. Both WR19BL/V and WR19BL carry EN and UL approval certifications, meeting the same regulatory and safety standards.

Q: What is the inventory status for substitution?

A: WR19BL is currently in active production with 1,181 pieces available in stock. WR19BL/V is obsolete with 733 pieces remaining in inventory. For new procurement, WR19BL is the recommended selection.
