KB26RKW01 Equivalent & Substitute Parts

Part Overview

The KB26RKW01 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 panel-mount front configuration 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 where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB26RKW01 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Voltage rating (125V AC minimum, 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Operating temperature range (-25°C to 70°C)
• RoHS compliance status

Allowable Variation Parameters:

• Current rating: The substitute may exceed the original 1A rating, provided it meets or exceeds the minimum requirement
• Mechanical and electrical life: The substitute may exceed the original cycle ratings
• Panel cutout diameter: Mechanical accommodation must be verified during integration
• Termination style: May differ if electrical connection requirements are satisfied
• Product status: Active status preferred for ongoing availability

The YB26RKW01 satisfies all mandatory compatibility parameters while providing enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB26RKW01 is a direct functional substitute for the KB26RKW01. Both components are manufactured by NKK Switches and maintain identical circuit configuration, switching function, and voltage ratings. The YB26RKW01 provides enhanced electrical performance with 3A current capacity versus the original 1A rating, and doubled mechanical and electrical life specifications.

Both parts maintain ROHS3 compliance and operate within the identical temperature range. The YB26RKW01 carries active product status, ensuring continued availability and supply chain reliability compared to the obsolete KB26RKW01.

Physical integration requires consideration of the increased panel cutout diameter (16.00mm versus 12.30mm) and the modified termination style, which includes quick-connect options in addition to solder capability. These differences are mechanical in nature and do not affect electrical compatibility within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can the YB26RKW01 directly replace the KB26RKW01 in existing designs?

A: Electrical compatibility is confirmed. The YB26RKW01 maintains identical circuit configuration (DPDT), switch function (On-On), and voltage ratings (125V AC, 30V DC). Physical integration requires verification of panel cutout accommodation, as the YB26RKW01 requires a 16.00mm diameter opening compared to the KB26RKW01's 12.30mm diameter.

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

A: The YB26RKW01 provides enhanced performance with 3A current rating (versus 1A), doubled mechanical life (200,000 cycles versus 100,000), and doubled electrical life (100,000 cycles versus 50,000). Termination options differ, with the YB26RKW01 offering both solder and quick-connect configurations. The YB26RKW01 maintains active product status.

Q: Are both parts RoHS compliant?

A: Yes. Both the KB26RKW01 and YB26RKW01 are ROHS3 compliant and REACH unaffected.

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

A: Both components operate within -25°C to 70°C, providing identical thermal performance specifications.

Q: Does the increased current rating of the YB26RKW01 affect compatibility?

A: No. The higher current rating (3A) of the YB26RKW01 is a performance enhancement that does not compromise compatibility with circuits designed for the original 1A rating. The substitute will operate safely in applications requiring 1A or less.
