WR19AFN/V Rocker Switch SPDT 15A 125V - Equivalent & Substitute Parts

Part Overview

The WR19AFN/V is a panel-mount rocker switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with 15A AC/DC current rating at 125V AC / 30V DC. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The switch provides On-Off-Momentary functionality with IP67 ingress protection and epoxy-sealed terminals suitable for harsh environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR19AFN/V is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPDT
• Current Rating: Must be 15A (AC/DC)
• Voltage Rating: Must support 125V AC and 30V DC minimum
• Mounting Type: Must be Panel Mount, Snap-In
• Actuator Type: Must be Concave (Curved)
• Termination Style: Must be Quick Connect - 0.250" (6.3mm)
• Panel Cutout Dimensions: Must be Rectangular - 34.20mm x 17.20mm
• Ingress Protection: Must be IP67
• Operating Temperature Range: Must support -25°C to 85°C
• Approval Agencies: Must include EN and UL certifications

The WR19AFN (without the /V suffix) meets all substitution criteria and is classified as an active product, making it a direct equivalent for the obsolete WR19AFN/V.

Parameter Comparison

Engineering Selection Recommendations

The WR19AFN is the direct substitute for the obsolete WR19AFN/V. Both components are manufactured by NKK Switches within the WR series and maintain identical electrical and mechanical specifications across all critical parameters. The WR19AFN carries active product status, ensuring ongoing availability and supply chain continuity.

The substitute part provides additional compliance documentation: ROHS3 compliance and REACH unaffected status are explicitly confirmed for the WR19AFN, supporting regulatory requirements in modern applications. Both parts carry EN and UL approvals, meeting international safety standards.

For applications currently using WR19AFN/V, direct substitution with WR19AFN is electrically and mechanically compatible without design modification. Panel cutout dimensions, termination interfaces, and mounting requirements remain identical.

Frequently Asked Questions (FAQ)

Q: Can WR19AFN replace WR19AFN/V in existing designs? A: Yes. The WR19AFN is a direct equivalent. All electrical ratings (15A at 125V AC / 30V DC), circuit configuration (SPDT), mechanical mounting (Panel Mount, Snap-In), and panel cutout dimensions (34.20mm x 17.20mm) are identical. No design changes are required.

Q: What is the difference between WR19AFN/V and WR19AFN? A: The primary difference is product status. WR19AFN/V is obsolete, while WR19AFN is active. The WR19AFN also provides explicit ROHS3 compliance and REACH unaffected documentation. All functional and mechanical parameters are equivalent.

Q: Are the termination connectors compatible? A: Yes. Both parts use Quick Connect - 0.250" (6.3mm) termination style. Existing wiring harnesses and connector interfaces are compatible without modification.

Q: Does the substitute part meet the same environmental specifications? A: Yes. Both parts maintain IP67 ingress protection (dust tight, waterproof), operate across -25°C to 85°C, and provide epoxy-sealed terminals. Environmental performance is equivalent.

Q: What packaging options are available for the substitute? A: The WR19AFN is supplied in bulk packaging. The original WR19AFN/V packaging specification was not defined in available documentation.

Q: Are both parts certified to the same standards? A: Yes. Both WR19AFN/V and WR19AFN carry EN and UL approvals. The substitute part additionally documents ROHS3 compliance and REACH unaffected status.
