KB15SKW01-6F-JB Equivalent & Substitute Parts

Part Overview

The KB15SKW01-6F-JB 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 green LED illumination at 3.3VDC nominal. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-6F-JB is determined by the following critical parameters:

• Circuit configuration must remain SPDT
• Switch function must be On-Mom (momentary)
• Illumination type and color must be LED, Green at 3.3VDC
• Mounting type must be Panel Mount, Front
• Actuator type must be Square, Button
• Operating temperature range must encompass -25°C ~ 50°C
• RoHS3 compliance must be maintained

The YB15SKW01-6F-JB qualifies as a substitute based on matching all core functional and electrical parameters. Differences in current rating, mechanical life, electrical life, panel cutout dimensions, and termination style represent design enhancements rather than functional incompatibilities, provided the application circuit can accommodate the higher current rating and alternative termination method.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-6F-JB is an active product with ROHS3 compliance and REACH unaffected status, providing regulatory continuity with the obsolete KB15SKW01-6F-JB. The substitute maintains identical voltage ratings, illumination specifications, and operating temperature range. The higher current rating (3A versus 1A) and extended mechanical/electrical life cycles represent design improvements compatible with applications originally specified for the KB15SKW01-6F-JB, provided circuit design accommodates the higher current capacity. Panel cutout dimension increase from 12.30mm to 16.00mm requires mechanical panel modification. Termination style change from Solder Lug to Solder with Quick Connect requires circuit board redesign for the alternative connection method.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-6F-JB directly replace the KB15SKW01-6F-JB without circuit modifications?

A: Electrical substitution is feasible due to matching voltage ratings, circuit configuration, and illumination specifications. However, the panel cutout dimension increase (12.30mm to 16.00mm) requires mechanical panel modification, and the termination style change necessitates circuit board redesign.

Q: What is the impact of the higher current rating on the KB15SKW01-6F-JB application?

A: The YB15SKW01-6F-JB's 3A rating exceeds the original 1A specification. This represents a design margin increase and does not create incompatibility, provided the application circuit is designed to handle the higher current capacity without adverse effects.

Q: Are there compliance differences between the two parts?

A: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence for applications subject to these standards.

Q: What mechanical considerations apply to panel integration?

A: The panel cutout diameter must be increased from 12.30mm to 16.00mm to accommodate the YB15SKW01-6F-JB. This requires panel modification or redesign.

Q: How do the mechanical and electrical life ratings differ?

A: The YB15SKW01-6F-JB provides extended life ratings: 1,000,000 mechanical cycles versus 100,000 for the KB15SKW01-6F-JB, and 100,000 electrical cycles versus 50,000. These improvements support higher-duty-cycle applications.
