KB26NKW01 Equivalent & Substitute Parts

Part Overview

The KB26NKW01 is a pushbutton switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 1A at 125V AC and 30V DC. This component features panel mount snap-in installation with solder lug termination and is designed for standard on-on switching applications. The KB26NKW01 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB26NKW01 is determined by the following critical parameters that must remain consistent or be upgraded:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Snap-In
• Operating temperature range: -25°C to 70°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Upgrade Parameters:

• Current rating: May be increased from 1A to higher ratings
• Electrical life: May be increased from 50,000 cycles
• Mechanical life: May be increased from 100,000 cycles
• Termination style: May differ if compatible with circuit board design

The YB26NKW01 qualifies as a substitute part because it maintains all mandatory parameters while providing enhanced electrical and mechanical life ratings, increased current capacity, and improved termination options.

Engineering Selection Recommendations

The YB26NKW01 is the qualified substitute for KB26NKW01 applications. Selection should be based on the following factors:

Product Status Consideration: The KB26NKW01 is obsolete, while YB26NKW01 maintains active product status with NKK Switches, ensuring continued availability and supply chain reliability.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Performance Enhancement: The YB26NKW01 provides doubled electrical life (100,000 cycles versus 50,000 cycles) and doubled mechanical life (200,000 cycles versus 100,000 cycles), supporting extended operational requirements.

Current Capacity: The YB26NKW01 supports 3A rating compared to the 1A rating of KB26NKW01. Applications requiring only 1A operation remain fully compatible with this upgrade.

Termination Compatibility: The YB26NKW01 offers dual termination options (Solder and Quick Connect 0.110"). Circuit board design must accommodate the selected termination method; solder lug compatibility is maintained.

Panel Cutout Consideration: The YB26NKW01 requires a 16.00mm circular panel cutout versus 12.30mm for KB26NKW01. Physical panel modifications may be necessary for direct replacement.

Frequently Asked Questions (FAQ)

Q: Can YB26NKW01 directly replace KB26NKW01 without circuit modifications?

A: Electrical compatibility is confirmed. The YB26NKW01 maintains identical voltage ratings, circuit configuration, and switch function. Termination style differences (solder lug versus solder/quick connect options) require verification against your circuit board design. Panel cutout diameter increase from 12.30mm to 16.00mm necessitates physical panel assessment.

Q: What is the significance of the current rating increase from 1A to 3A?

A: The YB26NKW01 supports higher current loads. Applications designed for 1A operation remain fully compatible and benefit from increased safety margin and reduced thermal stress on the component.

Q: Why does the YB26NKW01 have different panel cutout dimensions?

A: The larger 16.00mm circular cutout reflects the YB series design. Physical panel modifications are required if direct mechanical replacement is necessary. Electrical function remains unchanged.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both KB26NKW01 and YB26NKW01 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for equivalent applications.

Q: What is the practical difference between 100,000 and 200,000 mechanical life cycles?

A: The YB26NKW01 provides doubled mechanical life expectancy, extending component service intervals and reducing replacement frequency in high-cycle applications.

Q: Is the YB26NKW01 available for new designs?

A: Yes. The YB26NKW01 maintains active product status with NKK Switches, ensuring availability for both replacement and new design implementations.
