WR19BS/V Equivalent & Substitute Parts

Part Overview

The WR19BS/V is a rocker switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with 15A capacity at 125V AC. This panel-mount, snap-in switch features a concave ivory actuator with solder lug termination and IP67 ingress protection. The WR19BS/V is currently listed as obsolete, making identification of equivalent and substitute parts essential for ongoing maintenance, repair, and system continuity in applications requiring SPDT rocker switch functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WR19BS/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)

The WR19BS (without the /V suffix) from NKK Switches meets all specified electrical and mechanical parameters. This part maintains identical circuit configuration, current and voltage ratings, mounting specifications, and environmental protection characteristics. The primary distinction is product status: WR19BS/V is obsolete, while WR19BS is active in production.

Parameter Comparison

Engineering Selection Recommendations

The WR19BS is the direct substitute for the obsolete WR19BS/V. Both parts are manufactured by NKK Switches and share identical electrical specifications, mechanical dimensions, and environmental ratings. The WR19BS is currently in active production status with confirmed inventory availability (1,061 pieces in stock versus 725 pieces for the obsolete variant).

The WR19BS carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and system updates. Both parts maintain EN and UL approval agency certifications, ensuring compliance with international electrical safety standards.

For applications currently using WR19BS/V, direct replacement with WR19BS requires no circuit redesign, panel modification, or termination changes. The identical panel cutout dimensions (34.20mm x 17.20mm) and solder lug termination ensure mechanical and electrical compatibility without additional engineering work.

Frequently Asked Questions (FAQ)
