KB15CKW01 Equivalent & Substitute Parts
Part Overview
The KB15CKW01 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC and 30V DC. This component is designed for standard panel mount, front installation applications with a plunger actuator and solder lug termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and redesign applications where this switch is specified in existing designs.

Substitute Part Grouping Explanation
Substitution of the KB15CKW01 is determined by the following critical parameters that must remain compatible:
Mandatory Compatibility Parameters:
- Circuit configuration (SPDT)
- Switch function (On-Mom momentary operation)
- Voltage ratings (125V AC minimum, 30V DC minimum)
- Mounting type (Panel Mount, Front)
- Actuator type (Plunger for Cap)
- Operating temperature range (-25°C ~ 70°C)
- Regulatory compliance (ROHS3, REACH Unaffected)
Allowable Variation Parameters:
- Current rating (substitute must equal or exceed 1A)
- Mechanical and electrical life cycles (substitute must equal or exceed specified values)
- Panel cutout dimensions (physical installation space constraints)
- Termination style (may differ if mechanical compatibility is maintained)
The YB15CKW01 meets all mandatory compatibility requirements while exceeding performance specifications in current rating (3A vs 1A), mechanical life (1,000,000 vs 100,000 cycles), and electrical life (100,000 vs 50,000 cycles).

Engineering Selection Recommendations
The YB15CKW01 is a direct functional substitute for the obsolete KB15CKW01 based on electrical and mechanical compatibility. Both components are manufactured by NKK Switches and maintain identical ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.
The YB15CKW01 provides enhanced performance specifications across all critical durability metrics while maintaining identical voltage and temperature operating parameters. The active product status of the YB15CKW01 ensures long-term availability and supply chain stability compared to the obsolete KB15CKW01.
Physical installation considerations include panel cutout diameter increase from 12.30mm to 16.00mm and termination style variation from solder lug to solder with quick connect options. These differences require mechanical design verification for existing panel layouts and circuit board connection methods.
Frequently Asked Questions (FAQ)
Q: Can the YB15CKW01 directly replace the KB15CKW01 in existing designs?
A: Electrical and functional compatibility is confirmed. Physical installation compatibility requires verification of panel cutout dimensions (12.30mm vs 16.00mm) and termination method compatibility (solder lug vs solder/quick connect).
Q: What are the key differences between these two switches?
A: The YB15CKW01 exceeds the KB15CKW01 in current rating (3A vs 1A), mechanical life (1,000,000 vs 100,000 cycles), and electrical life (100,000 vs 50,000 cycles). Panel cutout diameter and termination options differ. Both maintain identical voltage ratings, circuit configuration, and operating temperature range.
Q: Is the YB15CKW01 available in the same packaging as the KB15CKW01?
A: The KB15CKW01 is packaged in standard format, while the YB15CKW01 is available in bulk packaging. Packaging format should be confirmed with the supplier based on procurement requirements.
Q: Do both switches meet the same regulatory standards?
A: Yes. Both the KB15CKW01 and YB15CKW01 are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.
Q: What installation considerations apply when substituting the YB15CKW01?
A: The larger panel cutout diameter (16.00mm vs 12.30mm) requires verification that existing panel openings can accommodate the substitute. Termination style differences (solder lug vs solder/quick connect) require circuit board connection method compatibility assessment.
