KB15SKW01-5C-JB Equivalent & Substitute Parts

Part Overview

The KB15SKW01-5C-JB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with integrated LED illumination. This component is rated for 1A at 125V AC and 30V DC, with a square button actuator and red LED indicator. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this series is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-5C-JB is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain switching logic compatibility
• Switch Function: Must be On-Mom (momentary) to preserve operational behavior
• Voltage Ratings: Must support minimum 125V AC and 30V DC to ensure safe operation within specified electrical limits
• Mounting Type: Must be Panel Mount, Front to ensure mechanical compatibility with existing panel cutouts
• Illumination: Must feature LED illumination with red color and 1.9 VDC nominal voltage for visual consistency
• Actuator Type: Must be square button configuration for ergonomic and aesthetic consistency
• Operating Temperature Range: Must encompass -25°C to 50°C minimum to maintain performance across specified environmental conditions
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The YB15SKW01-5C-JB qualifies as a substitute part. While it features a higher current rating (3A versus 1A) and enhanced mechanical/electrical life specifications, these represent improvements that do not compromise compatibility. The higher current rating provides additional design margin without creating incompatibility. The larger panel cutout diameter (16.00mm versus 12.30mm) and modified termination style (Solder, Quick Connect versus Solder Lug) require mechanical and electrical interface verification during implementation.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C-JB is the identified substitute for the obsolete KB15SKW01-5C-JB. Selection of this alternative is supported by the following engineering factors:

Product Status Alignment: The YB15SKW01-5C-JB maintains active product status with NKK Switches, ensuring ongoing availability and supply chain continuity compared to the obsolete KB series.

Electrical Compatibility: Both parts maintain identical voltage ratings (125V AC, 30V DC) and circuit configuration (SPDT). The increased current rating of the YB series (3A versus 1A) provides enhanced electrical capacity without creating incompatibility with existing designs rated for 1A operation.

Mechanical Compatibility: Both parts feature identical mounting type (Panel Mount, Front), actuator configuration (Square, Button), and operating temperature range (-25°C to 50°C). The panel cutout diameter difference (16.00mm versus 12.30mm) requires mechanical interface assessment for existing panel installations.

Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent product substitution.

Performance Enhancement: The YB series provides superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), extending component reliability in high-cycle applications.

Interface Modification: The termination style change from Solder Lug to Solder with Quick Connect (0.110" / 2.8mm) requires electrical connection redesign. This modification is necessary to accommodate the YB series design and must be evaluated during implementation planning.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C-JB directly replace the KB15SKW01-5C-JB without any modifications?

A: Electrical and functional compatibility is confirmed. However, two interface modifications are required: (1) Panel cutout enlargement from 12.30mm to 16.00mm diameter, and (2) Electrical termination redesign to accommodate Quick Connect terminals instead of Solder Lugs. These modifications must be completed during implementation.

Q: What is the significance of the higher current rating (3A) on the YB15SKW01-5C-JB?

A: The 3A rating on the YB series represents increased electrical capacity compared to the 1A rating of the KB series. This enhancement does not create incompatibility with designs rated for 1A operation. The higher rating provides additional design margin and supports applications requiring higher current switching capacity.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts maintain identical compliance status: ROHS3 compliant and REACH unaffected. No regulatory barriers exist for substitution from a compliance perspective.

Q: What is the impact of the panel cutout diameter difference?

A: The YB15SKW01-5C-JB requires a 16.00mm diameter panel cutout compared to 12.30mm for the KB15SKW01-5C-JB. Existing panel installations with 12.30mm cutouts will require mechanical modification to accommodate the larger diameter. New panel designs should specify the 16.00mm cutout dimension.

Q: How do the mechanical and electrical life ratings affect component selection?

A: The YB15SKW01-5C-JB provides superior durability with 1,000,000 mechanical cycles and 100,000 electrical cycles compared to 100,000 and 50,000 cycles respectively for the KB series. This enhancement extends component service life in high-cycle applications and reduces replacement frequency.

Q: What is the difference in termination style, and how does this affect installation?

A: The KB15SKW01-5C-JB uses Solder Lug termination, while the YB15SKW01-5C-JB uses Solder with Quick Connect (0.110" / 2.8mm) termination. This requires redesign of electrical connections. Quick Connect terminals provide faster assembly and disassembly compared to solder lug connections.

Q: Is the YB15SKW01-5C-JB the only available substitute?

A: Based on the provided substitute list, the YB15SKW01-5C-JB is the identified equivalent part meeting all critical substitution parameters for the obsolete KB15SKW01-5C-JB.
