KB26CKW01 Equivalent & Substitute Parts

Part Overview

The KB26CKW01 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, designed for standard panel mount front installation with solder lug termination. The product is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design applications where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26CKW01 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Front
• 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)
• Electrical life: May exceed 50,000 cycles
• Mechanical life: May exceed 100,000 cycles
• Panel cutout diameter: Variation acceptable if mechanical installation can be accommodated
• Termination style: Variation acceptable if electrical connection requirements are met

The YB26CKW01 qualifies as a substitute based on these criteria, offering enhanced electrical and mechanical performance characteristics while maintaining core functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The YB26CKW01 is suitable for applications currently using the KB26CKW01. The substitute part maintains identical voltage ratings (125V AC, 30V DC), circuit configuration (DPDT), and switching function (On-On), with identical operating temperature specifications (-25°C to 70°C).

The YB26CKW01 provides enhanced performance through higher current capacity (3A versus 1A) and extended mechanical and electrical life ratings (200,000 and 100,000 cycles respectively, compared to 100,000 and 50,000 cycles). Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The primary consideration is mechanical installation: the YB26CKW01 requires a 16.00mm panel cutout diameter compared to the KB26CKW01's 12.30mm diameter. Panel modifications may be necessary for direct substitution in existing installations.

Frequently Asked Questions (FAQ)

Q: Can the YB26CKW01 directly replace the KB26CKW01 in all applications?

A: Electrical compatibility is confirmed. The YB26CKW01 maintains identical voltage and circuit specifications. Mechanical compatibility depends on panel cutout dimensions: the YB26CKW01 requires a 16.00mm diameter opening versus the KB26CKW01's 12.30mm diameter. Existing panel installations may require modification.

Q: What is the significance of the higher current rating on the YB26CKW01?

A: The YB26CKW01 is rated for 3A compared to the KB26CKW01's 1A rating. This higher current capacity allows the substitute to handle applications with greater current demands while remaining suitable for lower-current applications originally designed for the KB26CKW01.

Q: Are there differences in termination between these parts?

A: Yes. The KB26CKW01 uses solder lug termination, while the YB26CKW01 offers solder and quick connect 0.110" (2.8mm) termination options. Termination style selection depends on circuit board design and assembly requirements.

Q: Do both parts meet the same regulatory standards?

A: Both the KB26CKW01 and YB26CKW01 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for electronic component applications.

Q: What is the practical difference in mechanical and electrical life ratings?

A: The YB26CKW01 provides doubled mechanical life (200,000 cycles versus 100,000 cycles) and doubled electrical life (100,000 cycles versus 50,000 cycles). This extended operational life may reduce maintenance frequency and component replacement cycles in high-duty applications.
