WR19ASN/V Equivalent & Substitute Parts

Part Overview

The WR19ASN/V is a rocker switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with a 15A rating at 125V AC. This panel-mount, snap-in switch features a concave black actuator with solder lug termination and IP67 ingress protection. The WR19ASN/V is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing maintenance, repair, and new design applications where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WR19ASN/V is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC, 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Termination style (Solder Lug)
• Panel cutout dimensions (34.20mm x 17.20mm)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications

The WR19ASN (without the /V suffix) from NKK Switches meets all these parameters and qualifies as a direct substitute. The primary distinction is product status: WR19ASN/V is obsolete, while WR19ASN is active in production.

Parameter Comparison

Engineering Selection Recommendations

The WR19ASN is the direct substitute for the obsolete WR19ASN/V. Both parts are manufactured by NKK Switches and share identical electrical, mechanical, and dimensional specifications. The WR19ASN is currently in active production status, ensuring availability for new designs and replacement applications.

The WR19ASN carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. Both parts maintain EN and UL approvals, confirming suitability for applications requiring these certifications.

For applications where the WR19ASN/V was originally specified, the WR19ASN provides full functional and physical compatibility without design modification or PCB rework.

Frequently Asked Questions (FAQ)

Q: Can WR19ASN directly replace WR19ASN/V without any modifications?

A: Yes. The WR19ASN is a direct substitute. All electrical ratings (15A at 125V AC, 30V DC), circuit configuration (SPDT), mechanical specifications (30,000 cycle life), panel cutout dimensions (34.20mm x 17.20mm), and termination style (solder lug) are identical. No circuit modifications or panel rework are required.

Q: What is the difference between WR19ASN/V and WR19ASN?

A: The primary difference is product status. WR19ASN/V is obsolete, while WR19ASN is active in production. The /V suffix on the original part number does not indicate a functional or electrical difference. The WR19ASN also carries ROHS3 compliance certification.

Q: Are there any compatibility concerns with panel mounting?

A: No. Both parts use identical panel mount, snap-in configuration with the same rectangular cutout dimensions (34.20mm x 17.20mm). Existing panel cutouts require no modification.

Q: Do both parts have the same ingress protection rating?

A: Yes. Both WR19ASN/V and WR19ASN maintain IP67 rating (dust tight, waterproof) with epoxy sealed terminals, suitable for the same environmental conditions.

Q: What certifications apply to the substitute part?

A: The WR19ASN carries EN and UL approvals, matching the original WR19ASN/V. Additionally, WR19ASN is ROHS3 compliant, meeting current environmental regulations.
