WR18AL/V Equivalent & Substitute Parts

Part Overview

The WR18AL/V is a rocker switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with a momentary-off-momentary (Mom-Off-Mom) switch function. This panel-mount, snap-in component is rated for 15A at 125V AC and 30V DC, featuring a concave black actuator and wire lead termination. The part is currently listed as obsolete, making identification of equivalent alternatives essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR18AL/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)
• Panel cutout dimensions (Rectangular - 34.20mm x 17.20mm)
• Actuator type and color (Concave, Black)
• Termination style (Wire Leads)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications

The WR18AL (without the /V suffix variant designation) from NKK Switches meets all these criteria and serves as the direct equivalent for the obsolete WR18AL/V.

Parameter Comparison

Engineering Selection Recommendations

The WR18AL serves as the direct functional equivalent to the obsolete WR18AL/V. Both components share identical electrical specifications, mechanical dimensions, and operational characteristics. The WR18AL is currently in active production status with confirmed inventory availability (1180 pcs in stock).

The WR18AL provides additional compliance advantages over the obsolete variant: it carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The moisture sensitivity level (MSL 1 - Unlimited) indicates superior handling flexibility compared to the original part designation.

For applications requiring the WR18AL/V, direct substitution with WR18AL is appropriate without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can WR18AL directly replace WR18AL/V in existing designs?

A: Yes. The WR18AL is electrically and mechanically identical to the WR18AL/V across all specified parameters. Panel cutout dimensions, mounting configuration, electrical ratings, and actuator specifications are equivalent. No circuit or mechanical redesign is required.

Q: What is the difference between WR18AL/V and WR18AL?

A: The /V suffix on the original part number indicates a variant designation that is no longer maintained by the manufacturer. The WR18AL represents the current production equivalent with identical functional specifications and improved regulatory compliance (ROHS3, REACH).

Q: Are there packaging differences between these parts?

A: The WR18AL/V was supplied in standard packaging, while the WR18AL is available in bulk packaging. Both use identical wire lead termination and panel-mount snap-in configuration.

Q: What compliance certifications apply to the substitute part?

A: The WR18AL carries EN and UL approvals (matching the original), with additional ROHS3 compliance and REACH unaffected status. These certifications meet current regulatory standards for electronic component use in industrial and commercial applications.

Q: Are the mechanical life and electrical life ratings the same?

A: Yes. Both the WR18AL/V and WR18AL are rated for 30,000 mechanical cycles and 10,000 electrical cycles, ensuring equivalent operational durability and reliability.
