Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB25SKW01-5C05-JC is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT
• Switch function must be On-Mom
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must support the application load

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Illumination type must be LED with red color
• Actuator type must be Square, Button
• Operating temperature range must encompass -25°C to 50°C

Interface Requirements:

• Panel cutout dimensions must be compatible with the installation cavity
• Termination style must be compatible with the circuit board or wiring harness

The YB25SKW01-5C05-JC meets the core electrical and mechanical criteria for substitution, with enhanced performance characteristics in current rating, mechanical life, and electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

The YB25SKW01-5C05-JC is a functionally equivalent substitute for the obsolete KB25SKW01-5C05-JC. The substitute maintains identical electrical ratings (125V AC, 30V DC) and circuit configuration (DPDT, On-Mom), with enhanced current capacity (3A versus 1A) and extended mechanical and electrical life ratings. The substitute is classified as Active product status, ensuring ongoing availability and supply chain continuity.

Key differences requiring design consideration include panel cutout diameter (16.00mm for substitute versus 12.30mm for original) and illumination voltage (1.9 VDC for substitute versus 5 VDC for original). Termination style differs (Solder Lug for original versus Solder and Quick Connect for substitute), necessitating interface verification during implementation.

Frequently Asked Questions (FAQ)

Q: Can the YB25SKW01-5C05-JC directly replace the KB25SKW01-5C05-JC in existing installations?

A: Electrical and functional compatibility is confirmed. Physical installation requires verification of panel cutout dimensions. The substitute requires a 16.00mm diameter cutout compared to the original 12.30mm diameter. Termination interface compatibility must be confirmed with the circuit board or wiring harness design.

Q: What is the impact of the different illumination voltage specifications?

A: The substitute operates at 1.9 VDC nominal illumination voltage compared to the original 5 VDC. This difference requires verification that the power supply or LED drive circuit can accommodate the lower voltage specification. The red LED color and illumination type remain identical.

Q: Are there mechanical life implications when substituting?

A: The substitute provides enhanced mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles). These represent performance improvements over the original specification and do not present compatibility concerns.

Q: What termination options are available with the substitute?

A: The YB25SKW01-5C05-JC offers dual termination options: Solder and Quick Connect (0.110" / 2.8mm). The original KB25SKW01-5C05-JC uses Solder Lug termination exclusively. Installation method selection depends on the circuit board or harness design requirements.

Q: Is the substitute compliant with current regulatory standards?

A: The substitute is manufactured by NKK Switches and is classified as Active product status. RoHS compliance status for the substitute was not specified in the available data. Regulatory compliance verification should be confirmed with the manufacturer or distributor for the specific application and region.
