KB25RKG01-5C-JC Equivalent & Substitute Parts

Part Overview

The KB25RKG01-5C-JC 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 red LED illumination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

The YB25RKG01-5C-JC qualifies as a functional substitute based on the following critical parameters that determine electrical and mechanical compatibility:

Matching Parameters:

• DPDT circuit configuration
• On-Mom switch function
• 0.4VA current rating (AC/DC)
• 28V AC and DC voltage ratings
• Rectangular button actuator with no marking
• Red LED illumination at 1.9 VDC nominal
• Panel mount, front installation
• Operating temperature range (-25°C to 50°C)
• ROHS3 compliance and REACH unaffected status

Allowable Variations:

• Series designation (KB vs. YB) reflects manufacturer product line evolution
• Product status transition (obsolete to active) indicates continued availability
• Termination style differs (solder lug vs. solder quick connect 0.110")
• Panel cutout dimensions vary (12.30mm vs. 16.00mm circular)
• Mechanical life rating increased (100,000 to 1,000,000 cycles)
• Packaging format (standard vs. bulk)

These variations are acceptable for substitution purposes as they do not affect the core electrical function or voltage/current specifications required for circuit operation.

Parameter Comparison

Engineering Selection Recommendations

The YB25RKG01-5C-JC is electrically and functionally equivalent to the KB25RKG01-5C-JC for applications requiring DPDT pushbutton switch operation at 28V with 0.4VA current capacity and red LED illumination. Both components maintain ROHS3 compliance and identical electrical specifications.

Selection of the YB25RKG01-5C-JC is supported by:

• Active product status ensuring continued availability and supply chain reliability
• Identical electrical ratings and circuit configuration
• Enhanced mechanical life rating (1,000,000 cycles vs. 100,000 cycles)
• Equivalent environmental compliance certifications

Physical integration considerations apply: the larger panel cutout diameter (16.00mm vs. 12.30mm) requires panel modification, and the termination style change (quick connect vs. solder lug) requires installation method adjustment. These are mechanical implementation factors, not electrical compatibility issues.

Frequently Asked Questions (FAQ)

Q: Can YB25RKG01-5C-JC directly replace KB25RKG01-5C-JC in existing assemblies?

A: Electrical substitution is valid. Physical installation requires assessment of panel cutout dimensions and termination method compatibility. The YB series uses a 16.00mm circular cutout versus the KB series 12.30mm cutout, and employs quick connect termination instead of solder lug.

Q: Are the voltage and current ratings identical between these parts?

A: Yes. Both components operate at 28V AC/DC with 0.4VA current rating. Illumination voltage is 1.9 VDC for both models.

Q: What is the difference in mechanical life between these switches?

A: The KB25RKG01-5C-JC is rated for 100,000 mechanical cycles, while the YB25RKG01-5C-JC is rated for 1,000,000 mechanical cycles. The YB series provides extended mechanical durability.

Q: Are both parts RoHS compliant?

A: Yes. Both KB25RKG01-5C-JC and YB25RKG01-5C-JC are ROHS3 compliant and REACH unaffected.

Q: Why is the KB25RKG01-5C-JC listed as obsolete?

A: Product status reflects manufacturer discontinuation. The YB25RKG01-5C-JC represents the active equivalent in the NKK Switches product line.

Q: What termination differences exist between these models?

A: KB25RKG01-5C-JC uses solder lug termination. YB25RKG01-5C-JC uses solder quick connect 0.110" (2.8mm) termination. Installation method must be selected based on circuit board design.
