WR18AFN/V Rocker Switch SPDT 15A 125V - Equivalent & Substitute Parts

Part Overview

The WR18AFN/V is a rocker switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with momentary-off-momentary (Mom-Off-Mom) switch function. Rated for 15A at 125V AC and 30V DC, this panel-mount snap-in switch is designed for applications requiring sealed, waterproof operation in industrial and commercial environments.

The WR18AFN/V is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for existing applications and new production runs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR18AFN/V is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC, 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Actuator type and color (Concave, Black)
• Termination style (Quick Connect - 0.250")
• Ingress protection rating (IP67)
• Panel cutout dimensions (34.20mm x 17.20mm)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications

The WR18AFN substitute part maintains identical electrical and mechanical specifications while differing in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The WR18AFN substitute part is functionally and mechanically equivalent to the WR18AFN/V across all critical electrical and mechanical parameters. The primary distinction is product status: WR18AFN/V is obsolete while WR18AFN is active in production.

For new designs and ongoing production requiring this switch specification, WR18AFN is the appropriate selection. The active product status ensures continued availability and supply chain support. WR18AFN carries ROHS3 compliance certification, meeting current environmental regulatory requirements.

Both parts share identical EN and UL approvals, confirming compliance with applicable safety and performance standards.

Frequently Asked Questions (FAQ)

Q: Can WR18AFN be used as a direct replacement for WR18AFN/V?

A: Yes. WR18AFN meets all electrical and mechanical specifications of WR18AFN/V, including circuit configuration, current and voltage ratings, mounting dimensions, and operating temperature range. The primary difference is product status and packaging format.

Q: What is the significance of the product status difference?

A: WR18AFN/V is classified as obsolete, indicating discontinued production. WR18AFN is active, ensuring ongoing manufacturing and supply availability. For applications requiring long-term component sourcing, WR18AFN is the recommended selection.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a rectangular panel cutout of 34.20mm x 17.20mm, ensuring mechanical compatibility in existing panel designs without modification.

Q: Do both parts use the same termination style?

A: Yes. Both WR18AFN/V and WR18AFN use Quick Connect termination with 0.250" (6.3mm) connectors, maintaining electrical interface compatibility.

Q: What is the difference in packaging between these parts?

A: WR18AFN/V packaging is listed as unspecified, while WR18AFN is supplied in bulk packaging. Packaging format does not affect functional or mechanical compatibility.

Q: Are there compliance differences between the two parts?

A: WR18AFN carries ROHS3 compliance certification. Both parts maintain EN and UL approvals. For applications subject to environmental compliance requirements, WR18AFN meets current regulatory standards.
