Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB25CKG01-6G-JB is determined by the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Mom momentary operation)
• Voltage rating (28V AC/DC minimum)
• Current rating (0.4VA minimum)
• Illumination type and color (LED, Blue)
• Mounting configuration (Panel Mount, Front)
• Actuator type (Round Button)
• Operating temperature range (-25°C to 50°C minimum)

The YB25CKG01-6G-JB from NKK Switches meets all critical electrical and mechanical parameters required for functional equivalence. Both components share identical circuit topology, voltage/current specifications, illumination characteristics, and environmental operating ranges. Differences in panel cutout dimensions, termination style, and mechanical life cycles represent design variations within the same functional category rather than substitution limitations.

Engineering Selection Recommendations

The YB25CKG01-6G-JB is a direct functional equivalent for KB25CKG01-6G-JB applications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete KB series.

Key considerations for implementation:

• Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical redesign of panel mounting interfaces
• Termination style changes from solder lug to solder with quick connect 0.110" (2.8mm) option, necessitating PCB layout and harness connector modifications
• Illumination voltage specification decreases from 3.6 VDC to 3.3 VDC; verify LED current-limiting circuit compatibility within this voltage range
• Mechanical life rating improves to 1,000,000 cycles, providing enhanced durability for high-cycle applications
• Both components maintain ROHS3 compliance and MSL 1 moisture sensitivity classification

Frequently Asked Questions (FAQ)

Q: Can YB25CKG01-6G-JB directly replace KB25CKG01-6G-JB without circuit modifications?

A: Electrical and functional compatibility is confirmed. However, mechanical panel modifications are required due to the 3.70mm increase in panel cutout diameter (12.30mm to 16.00mm). Termination style differences require PCB layout and connector harness updates.

Q: What is the impact of the 0.3 VDC illumination voltage difference?

A: The YB series operates at 3.3 VDC versus the KB series at 3.6 VDC. Existing LED current-limiting resistor values must be recalculated to maintain proper LED brightness and current draw within the substitute component's specifications.

Q: Are both components RoHS compliant?

A: The KB25CKG01-6G-JB is explicitly ROHS3 compliant. RoHS compliance status for the YB25CKG01-6G-JB is not specified in available documentation.

Q: What are the termination compatibility implications?

A: The KB series uses solder lug termination, while the YB series offers solder with quick connect 0.110" (2.8mm) options. PCB pad design and connector specifications must be updated accordingly.

Q: Does the 10x increase in mechanical life affect circuit design?

A: No. The improved mechanical life (1,000,000 cycles versus 100,000 cycles) represents enhanced component durability and does not require circuit modifications. This improvement is beneficial for high-cycle applications.

Q: Are both components suitable for the same operating temperature range?

A: Yes. Both components operate across -25°C to 50°C, maintaining identical environmental specifications.
