KB15KKW01-CC Equivalent & Substitute Parts

Part Overview

The KB15KKW01-CC 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, snap-in applications with a red square button actuator and solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15KKW01-CC is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Switch function must be On-Mom (momentary)
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must support the application load (minimum 1A)

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Snap-In
• Actuator type must be Square, Button
• Panel cutout dimensions must be compatible with existing mechanical interfaces
• Operating temperature range must encompass -25°C to 70°C

Regulatory & Compliance Requirements:

• RoHS3 compliance required
• REACH unaffected status required

The substitute part YB15KKW01-CB meets these criteria with enhanced electrical and mechanical performance characteristics while maintaining functional equivalence for SPDT momentary switching applications.

Parameter Comparison

Engineering Selection Recommendations

The YB15KKW01-CB serves as a direct functional substitute for the obsolete KB15KKW01-CC. Both components maintain identical electrical specifications for voltage and circuit configuration, with the substitute offering enhanced current capacity (3A versus 1A) and significantly improved mechanical and electrical life ratings.

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. Both components maintain full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment.

Design Consideration: The panel cutout diameter increases from 12.30mm to 16.00mm with the substitute part. Mechanical integration requires verification that the larger cutout dimension is compatible with existing panel mounting interfaces. The termination style change from solder lug to solder with quick connect option provides enhanced installation flexibility while maintaining electrical integrity.

Frequently Asked Questions (FAQ)

Q: Can YB15KKW01-CB directly replace KB15KKW01-CC in existing applications?

A: Electrical and functional compatibility is confirmed. The substitute maintains identical SPDT circuit configuration, momentary switch function, and voltage ratings (125V AC / 30V DC). Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical interface verification before installation.

Q: What are the key differences between these two components?

A: The primary differences are current rating (1A to 3A), mechanical life (100,000 to 1,000,000 cycles), electrical life (50,000 to 100,000 cycles), panel cutout diameter (12.30mm to 16.00mm), and termination options. The substitute includes stainless steel construction and a white filter/diffuser on the red actuator.

Q: Are both components RoHS compliant?

A: Yes. Both KB15KKW01-CC and YB15KKW01-CB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the operating temperature range for these switches?

A: Both components operate across -25°C to 70°C, providing equivalent thermal performance for standard industrial and commercial applications.

Q: Does the termination style change affect circuit performance?

A: No. The change from solder lug to solder with quick connect termination does not affect electrical performance. The quick connect option provides installation flexibility while maintaining equivalent electrical integrity and current-carrying capacity.

Q: Why is the KB15KKW01-CC listed as obsolete?

A: The KB15KKW01-CC has been discontinued by the manufacturer. The YB15KKW01-CB represents the active production alternative with enhanced performance characteristics and improved lifecycle ratings.
