WR19AT/V Rocker Switch SPDT 15A 125V - Equivalent & Substitute Parts

Part Overview

The WR19AT/V is a panel-mount rocker switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with 15A AC/DC current rating at 125V AC / 30V DC. The switch employs a concave black actuator with screw terminal connections and IP67 ingress protection. The WR19AT/V is classified as obsolete, making identification of equivalent active alternatives essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR19AT/V is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-Mom)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC / 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Actuator type and color (Concave, Black)
• Termination style (Screw Terminal)
• Ingress protection rating (IP67)
• Panel cutout dimensions (Rectangular - 34.20mm x 17.20mm)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications

The WR19AT (active product status) qualifies as a direct substitute for the obsolete WR19AT/V, maintaining identical electrical and mechanical specifications while offering current availability and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The WR19AT represents the direct active equivalent for the obsolete WR19AT/V. Both parts maintain identical electrical performance specifications, mechanical dimensions, and environmental ratings. The WR19AT offers the additional advantage of active product status with current manufacturing support and documented compliance certifications including ROHS3 and REACH unaffected status. For applications requiring the WR19AT/V, the WR19AT provides functional and dimensional compatibility with enhanced regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can the WR19AT directly replace the WR19AT/V in existing applications? A: Yes. The WR19AT maintains identical electrical ratings (15A at 125V AC / 30V DC), circuit configuration (SPDT), mechanical dimensions (34.20mm x 17.20mm panel cutout), mounting type (Panel Mount, Snap-In), and environmental specifications (IP67, -25°C to 85°C operating range). No circuit modifications or mechanical adjustments are required.

Q: What is the difference between the WR19AT/V and WR19AT part numbers? A: The WR19AT/V is classified as obsolete, while the WR19AT is an active product. Both share identical specifications. The suffix designation reflects product lifecycle status rather than functional differences.

Q: Are there packaging differences between these parts? A: The WR19AT/V packaging is listed as dash (unspecified), while the WR19AT is supplied in bulk packaging. Electrical and mechanical specifications remain unchanged regardless of packaging configuration.

Q: What compliance certifications apply to the WR19AT substitute? A: The WR19AT carries ROHS3 compliance and REACH unaffected status. Both parts maintain EN and UL approval agency certifications.

Q: Are the screw terminal connections identical between both parts? A: Yes. Both the WR19AT/V and WR19AT employ screw terminal termination with epoxy sealed terminals, maintaining identical connection specifications and environmental protection.
