KB15CKW01-CC Equivalent & Substitute Parts
Part Overview
The KB15CKW01-CC is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The switch is designed for standard panel mount, front installation with a round button actuator and solder lug termination.

Engineering Selection Recommendations
The YB15CKW01-CB serves as a direct functional substitute for the obsolete KB15CKW01-CC. Both components maintain identical circuit configuration (SPDT), switch function (On-Mom), voltage ratings (125V AC / 30V DC), and operating temperature range (-25°C to 70°C). Both components are ROHS3 compliant and carry MSL 1 rating.
The YB15CKW01-CB provides enhanced performance characteristics, including increased current rating (3A versus 1A), extended mechanical life (1,000,000 cycles versus 100,000 cycles), and doubled electrical life (100,000 cycles versus 50,000 cycles). The substitute part is currently in active production status, ensuring long-term availability.
Physical installation requires consideration of panel cutout dimensions. The YB15CKW01-CB requires a 16.00mm diameter cutout compared to the original 12.30mm specification. Termination options differ, with the substitute offering both solder and quick connect configurations in addition to the original solder lug option. These differences necessitate mechanical redesign of the panel mounting interface.
Frequently Asked Questions (FAQ)
Q: Can the YB15CKW01-CB directly replace the KB15CKW01-CC without circuit modifications?
A: Electrical substitution is valid. Both components feature identical SPDT circuit configuration, momentary switch function, and voltage ratings. However, mechanical panel modifications are required due to the larger 16.00mm cutout diameter of the substitute part compared to the original 12.30mm specification.
Q: What is the significance of the increased current rating in the YB15CKW01-CB?
A: The YB15CKW01-CB is rated for 3A (AC/DC) compared to the original 1A rating. This higher current capacity provides design margin for applications requiring increased switching capacity. The substitute part remains fully compatible with circuits designed for the original 1A specification.
Q: Are there termination compatibility considerations?
A: The original KB15CKW01-CC uses solder lug termination exclusively. The YB15CKW01-CB offers solder and quick connect (0.110" / 2.8mm) termination options. Circuit board modifications may be necessary if the original design accommodates only solder lug connections.
Q: Does the packaging format affect substitution eligibility?
A: The KB15CKW01-CC is supplied without specified packaging, while the YB15CKW01-CB is supplied in tray packaging. This difference does not affect electrical or mechanical compatibility but may impact procurement and inventory management procedures.
Q: Why is the mechanical life specification significantly higher for the substitute part?
A: The YB15CKW01-CB demonstrates 1,000,000 cycle mechanical life compared to 100,000 cycles for the original part. This enhanced durability reflects design improvements in the active YB series and provides extended service life for replacement applications.
Q: Is panel cutout modification the only mechanical change required?
A: Panel cutout enlargement from 12.30mm to 16.00mm is the primary mechanical modification. The actuator color differs slightly (red with white filter/diffuser on the substitute versus plain red on the original), and stainless steel construction is featured on the substitute part. These differences do not affect functional compatibility.
