WR13BS/V Equivalent & Substitute Parts

Part Overview

The WR13BS/V is a rocker switch manufactured by NKK Switches, classified as SPDT (Single Pole Double Throw) with On-Off-On functionality. This panel-mount, snap-in switch is rated for 15A at 125V AC and 30V DC, featuring a concave ivory actuator with solder lug termination and IP67 ingress protection. The WR13BS/V is currently listed as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR13BS/V is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Current rating: 15A (AC/DC)
• Voltage ratings: 125V AC and 30V DC
• Mounting type: Panel Mount, Snap-In
• Actuator type: Concave (Curved)
• Actuator color: Ivory
• Termination style: Solder Lug
• Ingress protection: IP67
• Panel cutout dimensions: Rectangular - 34.20mm x 17.20mm
• Operating temperature range: -25°C to 85°C
• Mechanical life: 30,000 Cycles
• Electrical life: 10,000 Cycles

The substitute part WR13BS meets all these criteria and is manufactured by the same supplier (NKK Switches) within the same WR series. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The WR13BS serves as a direct functional equivalent to the obsolete WR13BS/V. Both parts share identical electrical and mechanical specifications, including circuit configuration, current and voltage ratings, mounting dimensions, and operational characteristics. The WR13BS is currently in active production status with significantly higher inventory availability (29,088 pieces versus 1,067 pieces for the WR13BS/V).

The WR13BS carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and legacy system replacements. Both parts maintain EN and UL approval certifications. The substitution is electrically and mechanically transparent, requiring no design modifications or circuit board alterations.

Frequently Asked Questions (FAQ)

Q: Can WR13BS be used as a direct replacement for WR13BS/V in existing designs?

A: Yes. The WR13BS is electrically and mechanically identical to the WR13BS/V across all critical parameters: SPDT circuit, 15A/125V AC rating, 30V DC rating, On-Off-On function, panel mount snap-in configuration, and IP67 ingress protection. Panel cutout dimensions are identical at 34.20mm x 17.20mm.

Q: What is the difference between WR13BS/V and WR13BS?

A: The primary differences are product status and packaging. WR13BS/V is obsolete with limited inventory, while WR13BS is active production with bulk packaging. Both parts are manufactured by NKK Switches within the WR series and meet identical functional specifications.

Q: Are there any compliance differences between these parts?

A: The WR13BS includes ROHS3 compliance and REACH unaffected status documentation. Both parts maintain EN and UL approval certifications. The WR13BS is recommended for new designs requiring current regulatory compliance.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on matching: circuit configuration (SPDT), switch function (On-Off-On), current rating (15A AC/DC), voltage ratings (125V AC, 30V DC), mounting type (Panel Mount, Snap-In), actuator specifications (Concave, Ivory), termination style (Solder Lug), ingress protection (IP67), panel cutout dimensions (34.20mm x 17.20mm), and operating temperature range (-25°C to 85°C).

Q: Is the WR13BS suitable for applications requiring IP67 protection?

A: Yes. The WR13BS maintains IP67 ingress protection rating (dust tight, waterproof) with epoxy sealed terminals, identical to the WR13BS/V specification.

Q: What is the mechanical and electrical life expectancy?

A: Both parts are rated for 30,000 mechanical cycles and 10,000 electrical cycles under specified operating conditions within the -25°C to 85°C temperature range.
