WR19AS/V Equivalent & Substitute Parts

Part Overview

The WR19AS/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 WR19AS/V is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing maintenance, repair, and design continuity in applications requiring SPDT rocker switch functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WR19AS/V is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Current and Voltage Ratings: 15A (AC/DC) at 125V AC and 30V DC
• Mounting Specification: Panel mount with snap-in installation
• Actuator Characteristics: Concave curved profile in black
• Termination Method: Solder lug connections
• Environmental Protection: IP67 rating with epoxy sealed terminals
• Mechanical and Electrical Life: 30,000 mechanical cycles and 10,000 electrical cycles
• Panel Cutout Compatibility: Rectangular 34.20mm x 17.20mm opening

The WR19AS (bulk packaging variant) qualifies as a direct substitute based on identical electrical specifications, mechanical configuration, and environmental protection ratings.

Parameter Comparison

Engineering Selection Recommendations

The WR19AS serves as the direct substitute for the obsolete WR19AS/V. Both parts are manufactured by NKK Switches and maintain identical electrical, mechanical, and environmental specifications. The primary distinction is product status: WR19AS/V is obsolete while WR19AS is active and currently in production.

Selection of WR19AS is supported by:

• Regulatory Compliance: Both parts carry EN and UL approvals
• Active Production Status: WR19AS is actively manufactured, ensuring supply chain continuity
• RoHS3 Compliance: WR19AS meets RoHS3 requirements
• Identical Functional Parameters: No electrical or mechanical compromises in substitution
• Inventory Availability: WR19AS maintains higher stock levels (1139 pcs vs. 885 pcs)

For applications currently using WR19AS/V, transition to WR19AS presents no functional or compliance risks.

Frequently Asked Questions (FAQ)

Q: Can WR19AS directly replace WR19AS/V in existing designs?

A: Yes. WR19AS is a direct equivalent with identical circuit configuration (SPDT), current rating (15A AC/DC), voltage specifications (125V AC, 30V DC), mounting type (panel mount, snap-in), actuator profile (concave black), termination method (solder lug), ingress protection (IP67), and mechanical/electrical life ratings. Panel cutout dimensions are identical at 34.20mm x 17.20mm.

Q: What is the difference between WR19AS/V and WR19AS?

A: The primary difference is product status and packaging. WR19AS/V is obsolete, while WR19AS is active. WR19AS is supplied in bulk packaging, whereas WR19AS/V was supplied with different packaging specifications. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: Both parts carry identical approvals (EN, UL). WR19AS additionally carries RoHS3 compliance certification, which is advantageous for modern applications subject to RoHS regulations.

Q: Is the panel cutout dimension identical for both parts?

A: Yes. Both WR19AS/V and WR19AS require a rectangular panel opening of 34.20mm x 17.20mm, ensuring mechanical compatibility without panel modification.

Q: What is the operating temperature range for these switches?

A: Both parts operate across -25°C to 85°C, suitable for industrial and commercial applications within this thermal envelope.

Q: How many mechanical and electrical cycles are rated for these switches?

A: Both parts are rated for 30,000 mechanical cycles and 10,000 electrical cycles, providing equivalent service life expectations.
