WR18BL/V Equivalent & Substitute Parts

Part Overview

The WR18BL/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 an ivory concave actuator and IP67 ingress protection. The WR18BL/V is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for repair, maintenance, and new production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR18BL/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 and panel cutout dimensions (Panel Mount, Snap-In; Rectangular 34.20mm x 17.20mm)
• Actuator type and color (Concave, Ivory)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications (30,000 cycles mechanical, 10,000 cycles electrical)
• Termination style (Wire Leads)
• Regulatory approvals (EN, UL)

The WR18BL (base product number without the /V suffix variant) meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The WR18BL serves as the direct substitute for the obsolete WR18BL/V. Both components are manufactured by NKK Switches and share identical electrical, mechanical, and dimensional specifications. The primary distinction is product status: the WR18BL/V is obsolete, while the WR18BL is active and currently in production.

The WR18BL offers the additional advantage of ROHS3 compliance, meeting current environmental and regulatory standards. Both parts maintain EN and UL approvals, ensuring compatibility with applications requiring these certifications.

For new designs or component replacement, the WR18BL is the appropriate selection due to its active production status and regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the WR18BL directly replace the WR18BL/V in existing applications?

A: Yes. The WR18BL is electrically and mechanically identical to the WR18BL/V across all specified parameters, including circuit configuration, current and voltage ratings, mounting dimensions, actuator specifications, and environmental ratings. Direct substitution is supported.

Q: What is the difference between WR18BL/V and WR18BL?

A: The /V suffix on the WR18BL/V denotes a specific variant designation. The base part number WR18BL represents the current production equivalent. Both share identical functional and physical characteristics. The WR18BL/V is obsolete; the WR18BL is active.

Q: Are there any compliance differences between these parts?

A: The WR18BL includes ROHS3 compliance certification, while the WR18BL/V does not specify this status. Both maintain EN and UL approvals. For applications requiring ROHS3 compliance, the WR18BL is the appropriate choice.

Q: Will the WR18BL fit the same panel cutout as the WR18BL/V?

A: Yes. Both components share identical panel cutout dimensions of 34.20mm x 17.20mm (rectangular), and both use snap-in mounting. Physical installation is identical.

Q: What is the inventory status of these parts?

A: The WR18BL/V has 949 pieces in stock (obsolete status). The WR18BL has 1,044 pieces in stock (active status). For new procurement, the WR18BL is recommended due to its active production status.
