• Switch function: On-Mom (On-Momentary)
• Mounting type: Panel Mount, Front
• Illumination type: LED, Red
• Illumination voltage: 1.9 VDC
• Operating temperature range: -25°C to 50°C
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: May be equal to or greater than 1A
• Voltage ratings: Must meet or exceed 125V AC and 30V DC
• Mechanical and electrical life: May exceed specified values
• Panel cutout diameter: Mechanical accommodation required
• Termination style: Alternative termination acceptable if circuit integration permits
• Packaging format: May differ from original

The YB25SKW01-5C-JB qualifies as a substitute based on compliance with all mandatory matching parameters while providing enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB25SKW01-5C-JB is qualified as a direct substitute for the KB25SKW01-5C-JB based on functional equivalence and regulatory compliance. Both components are ROHS3 compliant and maintain identical circuit configuration, switch function, and illumination specifications.

The substitute part provides enhanced electrical performance with a current rating of 3A compared to the original 1A specification, and extended mechanical life of 1,000,000 cycles versus 100,000 cycles. These improvements represent upward compatibility without functional degradation.

The YB25SKW01-5C-JB maintains active product status, ensuring continued availability and supply chain reliability. The substitute is suitable for direct replacement in applications where the original KB25SKW01-5C-JB component is no longer obtainable.

Frequently Asked Questions (FAQ)

Q: Can the YB25SKW01-5C-JB be used as a direct replacement for KB25SKW01-5C-JB?

A: Yes. Both components share identical DPDT circuit configuration, on-momentary switch function, LED red illumination at 1.9 VDC, and panel-mount front installation. Voltage and temperature specifications are equivalent. The substitute provides higher current capacity (3A vs. 1A) and extended mechanical life, representing upward compatibility.

Q: What is the primary difference between these two parts?

A: The YB25SKW01-5C-JB provides enhanced electrical performance with 3A current rating versus 1A, and 1,000,000 cycle mechanical life versus 100,000 cycles. The substitute also features active product status compared to the obsolete KB25SKW01-5C-JB. Panel cutout diameter differs (16.00mm vs. 12.30mm), requiring mechanical accommodation in panel installations.

Q: Are there packaging differences between the main part and substitute?

A: Yes. The KB25SKW01-5C-JB uses standard packaging, while the YB25SKW01-5C-JB is supplied in tray packaging. Termination style also differs: the original uses solder lug termination, while the substitute offers solder and quick connect 0.110" (2.8mm) termination options.

Q: What compliance certifications apply to both parts?

A: Both the KB25SKW01-5C-JB and YB25SKW01-5C-JB are ROHS3 compliant. The YB25SKW01-5C-JB additionally carries REACH Unaffected status. Both components are classified under ECCN EAR99 and HTSUS 8536.50.9031.

Q: Are there any mechanical installation considerations when substituting?

A: Yes. The panel cutout diameter requirement differs: the original KB25SKW01-5C-JB requires a 12.30mm circular cutout, while the YB25SKW01-5C-JB requires a 16.00mm circular cutout. Panel modifications may be necessary to accommodate the larger diameter of the substitute component.
