KB15SKW01-BB Equivalent & Substitute Parts
Part Overview
The KB15SKW01-BB 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 square button actuator and solder lug termination. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation
Substitution eligibility for the KB15SKW01-BB is determined by the following critical parameters:
Mandatory Compatibility Parameters:
- Circuit configuration: SPDT
- Switch function: On-Mom
- Voltage rating: 125V AC minimum, 30V DC minimum
- Mounting type: Panel Mount, Front
- Actuator type: Square, Button
- Operating temperature range: -25°C to 70°C minimum
- RoHS compliance: ROHS3 Compliant
Allowable Variation Parameters:
- Current rating: May exceed 1A (higher current rating is acceptable for lower-current applications)
- Mechanical life: May exceed 100,000 cycles
- Electrical life: May exceed 50,000 cycles
- Panel cutout diameter: Larger diameter acceptable with mechanical redesign consideration
- Termination style: Alternative termination acceptable if circuit integration permits
- Packaging: Bulk or standard packaging acceptable
The YB15SKW01-BB meets all mandatory compatibility parameters while exceeding performance specifications in current rating (3A), mechanical life (1,000,000 cycles), and electrical life (100,000 cycles).

Engineering Selection Recommendations
The YB15SKW01-BB is a direct functional substitute for the obsolete KB15SKW01-BB. Both components are manufactured by NKK Switches and maintain identical SPDT circuit configuration, On-Mom switch function, and voltage specifications (125V AC / 30V DC).
The YB15SKW01-BB offers enhanced performance characteristics with 3A current rating (versus 1A), 1,000,000 mechanical life cycles (versus 100,000), and 100,000 electrical life cycles (versus 50,000). Both components maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating.
Design consideration: The YB15SKW01-BB requires a 16.00mm panel cutout diameter compared to the KB15SKW01-BB's 12.30mm diameter. Panel redesign or mechanical adaptation may be necessary for direct retrofit applications. The YB15SKW01-BB offers dual termination options (Solder and Quick Connect 0.110"), providing flexibility for circuit integration compared to the KB15SKW01-BB's solder lug termination.
Frequently Asked Questions (FAQ)
Q: Can the YB15SKW01-BB directly replace the KB15SKW01-BB in existing designs?
A: Functional replacement is possible. Electrical specifications are compatible. Panel cutout diameter differs (16.00mm versus 12.30mm), requiring mechanical panel modification. Termination style options differ; verify circuit integration compatibility.
Q: What are the key differences between these components?
A: Current rating increases from 1A to 3A. Mechanical life extends from 100,000 to 1,000,000 cycles. Electrical life extends from 50,000 to 100,000 cycles. Panel cutout diameter increases from 12.30mm to 16.00mm. Termination options expand from solder lug to solder and quick connect configurations.
Q: Are both components RoHS compliant?
A: Yes. Both KB15SKW01-BB and YB15SKW01-BB are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
Q: Why is the KB15SKW01-BB obsolete?
A: Product status reflects manufacturer discontinuation. The YB15SKW01-BB series represents the active product line from NKK Switches for this switch category.
Q: What packaging is available for the YB15SKW01-BB?
A: The YB15SKW01-BB is available in bulk packaging, compared to standard packaging for the KB15SKW01-BB.
