KB15CKW01-01-JC Equivalent & Substitute Parts

Part Overview

The KB15CKW01-01-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 includes neon red illumination at 110VAC. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15CKW01-01-JC is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained for electrical compatibility
• Switch Function: On-Mom (momentary) operation is required
• Mounting Interface: Panel mount, front configuration with compatible cutout dimensions
• Voltage Ratings: AC and DC voltage ratings must meet or exceed the original specification
• Current Rating: Substitute must support the required load current
• Illumination Compatibility: Illumination type and voltage must be compatible with system design
• Termination Style: Connection method must be compatible with existing wiring or PCB layout
• Environmental Compliance: RoHS and REACH compliance status must be verified

The YB15CKW01-5C05-JC qualifies as a substitute based on matching SPDT circuit, On-Mom function, panel mount configuration, and equivalent voltage ratings. However, differences in current rating, illumination technology, panel cutout diameter, and termination style require engineering evaluation for specific applications.

Engineering Selection Recommendations

The YB15CKW01-5C05-JC is an active product from NKK Switches and maintains ROHS3 and REACH compliance, making it suitable for new designs and legacy system replacements where the KB15CKW01-01-JC is no longer available.

Selection of the YB15CKW01-5C05-JC requires verification of the following application-specific factors:

• Panel Cutout Compatibility: The substitute requires a 16.00mm diameter cutout versus the original 12.30mm specification. Mechanical panel modification may be necessary.
• Illumination System: The substitute uses LED red illumination at 5VDC instead of neon at 110VAC. Illumination circuit redesign is required.
• Termination Interface: The substitute provides solder and quick connect 0.110" (2.8mm) termination versus solder lug on the original. Wiring interface modification is necessary.
• Current Capacity: The substitute provides 3A rating, exceeding the original 1A specification, offering improved margin for load applications.
• Lifecycle Performance: The substitute offers extended mechanical life (1,000,000 cycles) and electrical life (100,000 cycles) compared to the original.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKW01-5C05-JC be used as a direct drop-in replacement for the KB15CKW01-01-JC?

A: No. While both switches share SPDT circuit configuration and On-Mom function, the substitute differs in panel cutout diameter (16.00mm vs. 12.30mm), illumination technology (LED 5VDC vs. Neon 110VAC), and termination style (solder/quick connect vs. solder lug). Panel and circuit modifications are required.

Q: What are the key compatibility criteria for substituting the KB15CKW01-01-JC?

A: The substitute must maintain SPDT circuit topology, On-Mom switch function, panel mount configuration, and equivalent or superior voltage ratings (125V AC / 30V DC). Illumination type, panel cutout dimensions, and termination style must be evaluated against specific application requirements.

Q: Is the YB15CKW01-5C05-JC suitable for applications requiring 1A current rating?

A: Yes. The YB15CKW01-5C05-JC is rated for 3A (AC/DC), which exceeds the original 1A requirement and provides additional design margin for the application.

Q: What compliance certifications apply to both the original and substitute parts?

A: Both the KB15CKW01-01-JC and YB15CKW01-5C05-JC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Are there mechanical life differences between these switches?

A: Yes. The KB15CKW01-01-JC is rated for 100,000 mechanical cycles, while the YB15CKW01-5C05-JC is rated for 1,000,000 mechanical cycles, providing significantly extended operational life in the substitute.
