WR19AL/CUL Rocker Switch SPDT 15A 125V - Equivalent & Substitute Parts

Part Overview

The WR19AL/CUL is an active-status rocker switch manufactured by NKK Switches, designed for panel-mount, snap-in applications requiring SPDT (Single Pole Double Throw) switching functionality. This component operates at 15A (AC/DC) with a 125V AC / 30V DC voltage rating and features IP67 ingress protection for dust-tight, waterproof operation. The switch is suitable for industrial control, appliance, and equipment applications where reliable on-off-momentary switching is required. Identifying equivalent substitute parts is necessary when managing inventory constraints, ensuring supply chain continuity, or matching specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR19AL/CUL rocker switch is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPDT (Single Pole Double Throw)
• Current Rating: Must be 15A (AC/DC)
• Voltage Ratings: Must support 125V AC and 30V DC minimum
• Mounting Type: Must be Panel Mount, Snap-In
• Actuator Type: Must be Concave (Curved)
• Actuator Color: Must be Black
• Termination Style: Must be Wire Leads
• Ingress Protection: Must be IP67
• Panel Cutout Dimensions: Must be Rectangular - 34.20mm x 17.20mm
• Operating Temperature Range: Must support -25°C to 85°C
• Mechanical Life: Must be 30,000 Cycles minimum
• Electrical Life: Must be 10,000 Cycles minimum
• Compliance: Must maintain ROHS3 compliance and EN/UL approvals

Parts meeting all these criteria are classified as direct equivalents and may be substituted without circuit redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The WR19AL substitute part is a direct equivalent to the WR19AL/CUL main part. Both components are manufactured by NKK Switches, carry active product status, and maintain identical electrical specifications, mechanical characteristics, and compliance certifications. The WR19AL meets all substitution criteria and may be selected interchangeably in applications requiring SPDT rocker switch functionality at 15A / 125V AC operation with IP67 environmental protection and panel-mount snap-in installation.

Both parts maintain ROHS3 compliance and EN/UL regulatory approvals, ensuring suitability for industrial and commercial equipment applications. Inventory availability should be the primary selection criterion between these equivalent parts.

Frequently Asked Questions (FAQ)

Q: Can the WR19AL be used as a direct replacement for the WR19AL/CUL?

A: Yes. The WR19AL is a direct equivalent. All electrical ratings (15A, 125V AC, 30V DC), mechanical specifications (panel cutout dimensions, snap-in mounting), actuator characteristics (concave, black), and compliance certifications (ROHS3, EN, UL) are identical.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires matching: SPDT circuit configuration, 15A current rating, 125V AC / 30V DC voltage ratings, panel-mount snap-in mounting, concave black actuator, wire lead termination, IP67 ingress protection, 34.20mm x 17.20mm panel cutout dimensions, -25°C to 85°C operating temperature range, 30,000 mechanical cycles, 10,000 electrical cycles, and ROHS3 / EN / UL compliance.

Q: Are there any packaging or inventory differences between these parts?

A: Both parts are supplied in bulk packaging. The WR19AL/CUL has 885 pieces in stock, while the WR19AL has 700 pieces in stock. Packaging format and handling specifications are identical.

Q: What is the panel cutout requirement for installation?

A: Both parts require a rectangular panel cutout of 34.20mm x 17.20mm for snap-in mounting. This dimension is identical across all equivalent parts in this group.

Q: Are these switches suitable for outdoor or harsh environments?

A: Yes. Both parts feature IP67 ingress protection (dust tight, waterproof) and operate across the -25°C to 85°C temperature range, making them suitable for industrial control and equipment applications in challenging environmental conditions.
