KB26CKG01-6F-JB Equivalent & Substitute Parts

Part Overview

The KB26CKG01-6F-JB is a pushbutton switch manufactured by NKK Switches, featuring DPDT (Double Pole Double Throw) circuitry with illuminated panel mount design. This component operates at 28V AC/DC with a 0.4VA current rating and includes green LED illumination at 3.3VDC nominal. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB26CKG01-6F-JB is determined by the following critical parameters:

• Circuit configuration (DPDT required)
• Switch function (On-On operation)
• Electrical ratings (0.4VA at 28V AC/DC)
• Illumination specifications (LED, green, 3.3VDC)
• Mounting configuration (Panel Mount, Front)
• Actuator type (Round Button)
• Operating temperature range (-25°C to 50°C minimum)
• Regulatory compliance (ROHS3, REACH status)

The YB26CKG01-6F-JB meets all core electrical and functional requirements. Differences in panel cutout dimensions, termination style, and mechanical life rating represent design variations within the same functional category and do not preclude substitution in applications where these parameters are compatible with the target system.

Parameter Comparison

Engineering Selection Recommendations

The YB26CKG01-6F-JB is an active production equivalent for the obsolete KB26CKG01-6F-JB. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current applications.

Selection of the YB26CKG01-6F-JB is appropriate when:

• Panel cutout diameter of 16.00mm accommodates the larger mechanical footprint
• Termination compatibility with Quick Connect 0.110" (2.8mm) terminals is acceptable or preferred over solder lug configuration
• Extended mechanical life rating of 200,000 cycles provides design margin for high-cycle applications

The KB26CKG01-6F-JB should be retained only for existing inventory applications where panel cutout dimensions and solder lug termination are fixed design constraints.

Frequently Asked Questions (FAQ)

Q: Can the YB26CKG01-6F-JB directly replace the KB26CKG01-6F-JB in existing designs?

A: Direct replacement requires verification of two mechanical parameters: panel cutout diameter (16.00mm vs. 12.30mm) and termination style compatibility (Quick Connect vs. Solder Lug). Electrical and functional specifications are identical.

Q: What is the significance of the different mechanical life ratings?

A: The YB26CKG01-6F-JB provides 200,000 mechanical cycles versus 100,000 for the KB26CKG01-6F-JB. This represents extended durability and is not a limitation for substitution; applications requiring only 100,000 cycles remain fully supported.

Q: Are there compliance differences between these parts?

A: Both components maintain identical RoHS3 compliance and REACH unaffected status. No regulatory barriers exist to substitution.

Q: What termination style should I select for new designs?

A: Termination selection depends on PCB design and assembly process. Solder Lug (KB26CKG01-6F-JB) requires manual soldering; Quick Connect 0.110" (2.8mm) (YB26CKG01-6F-JB) supports automated assembly with standard quick-connect receptacles.

Q: Is the YB series a direct successor to the KB series?

A: The YB26CKG01-6F-JB shares identical electrical specifications and illumination characteristics with the KB26CKG01-6F-JB. The YB series represents an active production line with enhanced mechanical durability and alternative termination options.
