KB26CKW01-CC Equivalent & Substitute Parts

Part Overview

The KB26CKW01-CC is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with On-On switching function. This component is rated for 1A at 125V AC and 30V DC, with a round red button actuator and solder lug termination. The product is 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 of the KB26CKW01-CC is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain DPDT
• Switch function must remain On-On
• Voltage ratings must meet or exceed the original specification (125V AC minimum, 30V DC minimum)
• Current rating must meet or exceed 1A

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Round, Button
• Panel cutout dimensions must accommodate the replacement component or allow for mechanical adaptation

Environmental & Compliance Requirements:

• Operating temperature range must encompass -25°C to 70°C
• RoHS3 compliance required
• Moisture Sensitivity Level 1 preferred for unlimited shelf life

The YB26WCKW01-CB qualifies as a substitute because it maintains DPDT On-On configuration, exceeds the voltage and current ratings of the original part, and meets all environmental and compliance criteria. However, differences in panel cutout diameter (16.00mm vs. 12.30mm), termination style, and ingress protection rating must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB26WCKW01-CB is an active product from NKK Switches and represents a direct functional upgrade path from the obsolete KB26CKW01-CC. Both components maintain identical voltage ratings and circuit topology, ensuring electrical compatibility in existing designs.

The substitute part provides enhanced performance characteristics: current rating increased from 1A to 3A, mechanical life doubled from 100,000 to 200,000 cycles, and electrical life doubled from 50,000 to 100,000 cycles. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Physical integration requires evaluation of the panel cutout diameter increase from 12.30mm to 16.00mm. The termination style differs (solder lug versus solder with quick connect option), and the substitute includes IP65 ingress protection rating not present in the original specification.

Frequently Asked Questions (FAQ)

Q: Can YB26WCKW01-CB directly replace KB26CKW01-CC in existing applications?

A: Electrical substitution is valid due to matching DPDT On-On configuration and voltage ratings. Mechanical integration requires panel cutout modification to accommodate the larger 16.00mm diameter. Termination style differences must be addressed during installation.

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

A: The substitute part offers higher current capacity (3A vs. 1A), extended mechanical and electrical life ratings, IP65 ingress protection, and active product status. Panel cutout diameter and termination options differ between the two models.

Q: Are both components RoHS compliant?

A: Yes, both KB26CKW01-CC and YB26WCKW01-CB are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the significance of the panel cutout diameter difference?

A: The KB26CKW01-CC requires a 12.30mm circular cutout, while YB26WCKW01-CB requires 16.00mm. Existing panel designs must be modified or adapted to accommodate the larger diameter of the substitute component.

Q: Does the substitute part support the same voltage specifications?

A: Yes, both components are rated for 125V AC and 30V DC, maintaining identical voltage compatibility.

Q: What packaging options are available?

A: KB26CKW01-CC is supplied without specified packaging designation. YB26WCKW01-CB is supplied in Tray packaging.
