KB26CKG01-05-FF Equivalent & Substitute Parts

Part Overview

The KB26CKG01-05-FF is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with incandescent illumination. This panel-mount component is rated for 0.4VA at 28V AC/DC and is designed for on-on switching applications with a green illuminated actuator. The product is currently obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB26CKG01-05-FF is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current rating must support 0.4VA minimum at 28V AC/DC
• Voltage rating must be rated for 28V AC and 28V DC operation

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Round Button
• Panel cutout diameter must accommodate the physical installation envelope

Operational Requirements:

• Operating temperature range must encompass -25°C to +50°C
• Mechanical and electrical life ratings must meet or exceed 100,000 cycles

Compliance Requirements:

• RoHS3 compliance status must be maintained

The YB26CKG01-5F05-JF meets all electrical and mechanical compatibility criteria while offering enhanced performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The YB26CKG01-5F05-JF is a functionally equivalent substitute for the obsolete KB26CKG01-05-FF based on matching electrical specifications (DPDT circuit, On-On function, 0.4VA at 28V AC/DC) and mechanical compatibility (panel mount, round button actuator, identical operating temperature range).

Key Advantages of Substitution:

• Active product status ensures long-term availability and supply chain continuity
• Enhanced mechanical life rating (200,000 cycles vs. 100,000 cycles) provides extended operational durability
• LED illumination technology replaces incandescent, offering improved reliability and reduced power consumption

Installation Considerations:

• Panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification
• Termination style changes from Solder Lug to Solder with Quick Connect option, requiring wiring harness adaptation
• Illumination voltage changes from 5 VAC to 2 VDC, requiring circuit modification to the illumination supply

The substitute part maintains full electrical and functional compatibility while requiring mechanical and electrical integration adjustments.

Frequently Asked Questions (FAQ)

Q: Can the YB26CKG01-5F05-JF directly replace the KB26CKG01-05-FF without any modifications?

A: The YB26CKG01-5F05-JF is electrically and functionally equivalent but requires three integration modifications: panel cutout enlargement from 12.30mm to 16.00mm diameter, termination harness reconfiguration from solder lug to quick connect terminals, and illumination supply voltage adjustment from 5 VAC to 2 VDC.

Q: What are the critical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: DPDT circuit configuration, On-On switch function, 0.4VA current rating at 28V AC/DC, panel mount front installation, round button actuator, and operating temperature range of -25°C to +50°C.

Q: Why does the panel cutout diameter differ between these parts?

A: The KB26CKG01-05-FF requires a 12.30mm circular cutout, while the YB26CKG01-5F05-JF requires a 16.00mm circular cutout. This dimensional difference reflects the physical envelope of each component design and necessitates panel modification for substitution.

Q: What is the impact of changing from incandescent to LED illumination?

A: The illumination voltage requirement changes from 5 VAC to 2 VDC. This requires modification to the illumination circuit supply. LED technology provides improved reliability, longer operational life, and reduced power consumption compared to incandescent illumination.

Q: Are there any compliance or certification differences between these parts?

A: The KB26CKG01-05-FF is specified as ROHS3 compliant. RoHS compliance status for the YB26CKG01-5F05-JF is not provided in the available data and should be verified with the manufacturer if RoHS compliance is a system requirement.
