WR18BT/V Equivalent & Substitute Parts

Part Overview

The WR18BT/V is a rocker switch manufactured by NKK Switches, configured as a Single Pole Double Throw (SPDT) momentary-off-momentary switch rated for 15A at 125V AC. The switch features a panel-mount snap-in design with screw terminals, concave ivory actuator, and IP67 ingress protection with epoxy sealed terminals.

The WR18BT/V is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support existing installations requiring component replacement or repair.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR18BT/V is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC, 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Termination style (Screw Terminal)
• Panel cutout dimensions (34.20mm x 17.20mm)
• Ingress protection rating (IP67)

Parts meeting all these criteria are classified as direct equivalents. Variations in product status, packaging, or compliance certifications do not affect functional substitutability when all electrical and mechanical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The WR18BT is a direct functional equivalent to the WR18BT/V. All electrical and mechanical parameters are identical, including circuit configuration, current and voltage ratings, mounting specifications, and ingress protection rating.

The primary distinction is product status: WR18BT/V is obsolete, while WR18BT is active. The WR18BT carries ROHS3 compliance certification, meeting current regulatory requirements for new designs and procurement. Both parts maintain EN and UL approvals.

For applications requiring component replacement or new procurement, the WR18BT is the appropriate selection due to active product status and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can WR18BT replace WR18BT/V in existing installations?

A: Yes. The WR18BT is a direct functional equivalent. All electrical ratings (15A at 125V AC, 30V DC), circuit configuration (SPDT Mom-Off-Mom), mounting type (panel mount snap-in), termination style (screw terminal), and mechanical specifications are identical. Panel cutout dimensions match exactly at 34.20mm x 17.20mm.

Q: What is the difference between WR18BT/V and WR18BT?

A: The WR18BT/V is classified as obsolete, while WR18BT is active. The WR18BT includes ROHS3 compliance certification. All functional and electrical parameters are identical.

Q: Are there packaging differences between these parts?

A: WR18BT/V is supplied with standard packaging. WR18BT is supplied in bulk packaging. This distinction does not affect component functionality or compatibility.

Q: What certifications apply to both parts?

A: Both WR18BT/V and WR18BT carry EN and UL approvals. The WR18BT additionally carries ROHS3 compliance.

Q: Can I use WR18BT in a design originally specified for WR18BT/V?

A: Yes. The WR18BT meets or exceeds all specifications of the WR18BT/V. The identical electrical ratings, mechanical dimensions, and mounting configuration ensure direct compatibility.
