KB15SKW01-5C24-JC Equivalent & Substitute Parts

Part Overview

The KB15SKW01-5C24-JC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with illuminated panel mount design. This component is rated for 1A at 125V AC and 30V DC, with red LED illumination at 24VDC nominal voltage. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this series is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

The YB15SKW01-5C24-JC qualifies as a functional substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: SPDT (identical)
• Switch function: On-Mom momentary operation (identical)
• Voltage ratings: 125V AC and 30V DC (identical)
• Illumination: LED, Red at 24VDC nominal (identical)
• Mounting: Panel Mount, Front (identical)
• Actuator type: Square, Button (identical)
• Operating temperature range: -25°C to 50°C (identical)
• Termination style: Solder connection (compatible, with extended options)
• RoHS and REACH compliance: ROHS3 Compliant, REACH Unaffected (identical)

Differing Parameters:

• Current rating: 3A (substitute) versus 1A (original) — higher rating provides design margin
• Panel cutout diameter: 16.00mm (substitute) versus 12.30mm (original) — requires panel modification
• Mechanical life: 1,000,000 cycles (substitute) versus 100,000 cycles (original) — enhanced durability
• Electrical life: 100,000 cycles (substitute) versus 50,000 cycles (original) — extended operational life
• Product status: Active (substitute) versus Obsolete (original) — ongoing availability
• Termination options: Solder with Quick Connect 0.110" (substitute) versus Solder Lug only (original)

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C24-JC is an active product with current manufacturer support and full ROHS3 compliance, addressing the obsolescence status of the KB15SKW01-5C24-JC. The substitute maintains electrical equivalence across all critical switching parameters: SPDT circuit, momentary function, 125V AC / 30V DC ratings, and 24VDC red LED illumination.

The higher current rating of 3A provides operational margin for the original 1A specification. Enhanced mechanical and electrical life ratings (1,000,000 and 100,000 cycles respectively) extend component durability beyond the original specifications.

Panel integration requires accommodation of the larger 16.00mm cutout diameter compared to the original 12.30mm specification. Termination flexibility in the substitute (solder with quick-connect option) offers installation advantages over the solder lug-only configuration of the original part.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C24-JC directly replace the KB15SKW01-5C24-JC without circuit modifications?

A: Electrical circuit compatibility is confirmed. The SPDT configuration, voltage ratings, current capacity, and illumination specifications are functionally equivalent. Panel cutout diameter modification is required due to the 16.00mm (substitute) versus 12.30mm (original) difference.

Q: What is the impact of the 3A current rating on a circuit designed for 1A?

A: The higher current rating of the substitute does not negatively affect circuits designed for 1A operation. The component will function within its rated parameters at lower current levels. Circuit design remains valid.

Q: Are there differences in mechanical durability between these parts?

A: The substitute provides enhanced mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles). These represent improvements over the original specification.

Q: What packaging considerations apply to the YB15SKW01-5C24-JC?

A: The substitute is supplied in bulk packaging. Termination options include both solder and quick-connect 0.110" (2.8mm) configurations, providing installation flexibility not available in the original solder lug-only design.

Q: Are compliance certifications maintained with the substitute part?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. The substitute is an active product with current manufacturer support, whereas the original is obsolete.
