KB15SKW01-CC Equivalent & Substitute Parts

Part Overview

The KB15SKW01-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 designed for standard panel mount applications with front-facing installation. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15SKW01-CC is determined by the following critical parameters:

Circuit configuration must remain SPDT to maintain electrical compatibility with existing designs. Switch function must be On-Mom (momentary action) to preserve operational behavior. Voltage ratings must meet or exceed the original specifications: 125V AC minimum and 30V DC minimum. Current rating must be equal to or greater than 1A to ensure safe operation under design load conditions.

Mounting type must be Panel Mount, Front to ensure mechanical compatibility with existing panel cutouts and installation procedures. Actuator type must be Square, Button to maintain user interface consistency. Operating temperature range must encompass or exceed -25°C to 70°C. RoHS3 compliance is required to meet current regulatory standards.

The YB15SKW01-CB qualifies as a substitute based on these criteria: it maintains SPDT circuit configuration, On-Mom function, meets voltage requirements (125V AC, 30V DC), exceeds current rating (3A versus 1A), and maintains Panel Mount, Front installation compatibility. However, mechanical and termination differences require evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-CB is available as an active product from NKK Switches, whereas the KB15SKW01-CC is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

The YB15SKW01-CB provides enhanced electrical and mechanical performance characteristics: 3A current rating (versus 1A), 1,000,000 mechanical cycles (versus 100,000), and 100,000 electrical cycles (versus 50,000). These improvements provide additional design margin for applications requiring extended component life or higher switching loads.

Key differences requiring evaluation: Panel cutout diameter increases from 12.30mm to 16.00mm, necessitating panel modification or adapter consideration. Termination style changes from Solder Lug to Solder with Quick Connect 0.110" (2.8mm) options, requiring circuit board redesign or connector adaptation. The YB15SKW01-CB includes tactile feedback feature not present in the original component.

For direct replacement in existing designs with minimal modification, the YB15SKW01-CB is suitable provided panel cutout and termination compatibility can be addressed. For new designs, the YB15SKW01-CB is the recommended selection due to active product status and superior performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-CB directly replace the KB15SKW01-CC without any modifications?

A: Electrical substitution is valid based on circuit configuration, voltage, and current ratings. However, mechanical modifications are required: the panel cutout diameter must be enlarged from 12.30mm to 16.00mm, and termination connections must be adapted from Solder Lug to the Quick Connect or Solder termination style of the YB15SKW01-CB.

Q: What are the critical parameters that determine substitution compatibility?

A: Circuit configuration (SPDT), switch function (On-Mom), voltage ratings (125V AC minimum, 30V DC minimum), current rating (1A or greater), mounting type (Panel Mount, Front), and operating temperature range (-25°C to 70°C) are the primary criteria. All must be maintained or exceeded in the substitute component.

Q: Why does the YB15SKW01-CB have a larger panel cutout diameter?

A: The YB15SKW01-CB is a different product series (YB versus KB) with different mechanical specifications. The 16.00mm diameter reflects the physical design of this component family and is not adjustable.

Q: Is the tactile feedback feature of the YB15SKW01-CB compatible with the original design?

A: Tactile feedback is an additional feature that does not negatively impact compatibility. It provides enhanced user feedback during switch actuation and is considered a performance improvement.

Q: Are both components RoHS compliant?

A: Yes, both the KB15SKW01-CC and YB15SKW01-CB are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the difference in electrical life between these components?

A: The KB15SKW01-CC has 50,000 electrical cycles, while the YB15SKW01-CB has 100,000 electrical cycles. The YB15SKW01-CB provides double the electrical life rating, offering extended operational durability for switching applications.
