Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB25RKW01-5C-JB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: DPDT
• Switch function: On-Mom
• Voltage rating: 125V AC minimum, 30V DC minimum
• Mounting type: Panel Mount, Front
• Illumination: LED, Red at 1.9VDC nominal
• Operating temperature range: -25°C to 50°C minimum
• RoHS3 compliance

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher current rating is acceptable for lower-current applications)
• Mechanical and electrical life: May exceed specified values
• Panel cutout diameter: Larger diameter acceptable with mechanical redesign consideration
• Termination style: Alternative termination acceptable if electrical connection is maintained
• Product status: Active status preferred for long-term availability

The YB25RKW01-5C-JB meets all mandatory compatibility parameters while exceeding performance specifications in current rating (3A), mechanical life (1,000,000 cycles), and electrical life (100,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB25RKW01-5C-JB is a direct functional substitute for the obsolete KB25RKW01-5C-JB. Both components maintain identical electrical specifications for voltage and circuit configuration, with the substitute offering enhanced performance characteristics in current capacity and operational life cycles. The substitute maintains full compliance with ROHS3 and REACH regulatory requirements.

The primary design consideration is the panel cutout diameter difference: KB25RKW01-5C-JB requires a 12.30mm circular cutout, while YB25RKW01-5C-JB requires a 16.00mm circular cutout. This dimensional change necessitates mechanical panel redesign or use of an adapter bezel if retrofitting into existing enclosures.

Termination style differs between the two components: the main part uses solder lug termination, while the substitute offers solder and quick-connect 0.110" (2.8mm) termination options. Electrical connection compatibility must be verified against the specific application's wiring harness configuration.

Frequently Asked Questions (FAQ)

Q: Can the YB25RKW01-5C-JB directly replace the KB25RKW01-5C-JB in existing designs?

A: Electrical substitution is valid. The higher current rating (3A vs. 1A) and extended operational life cycles of the YB25RKW01-5C-JB are compatible with applications designed for the KB25RKW01-5C-JB. However, mechanical panel modifications are required due to the larger 16.00mm cutout diameter compared to the original 12.30mm specification.

Q: What are the key differences between these two components?

A: The primary differences are current rating (1A to 3A), mechanical life (100,000 to 1,000,000 cycles), electrical life (50,000 to 100,000 cycles), panel cutout diameter (12.30mm to 16.00mm), and termination options. All electrical parameters including voltage ratings, circuit configuration, and illumination specifications remain identical.

Q: Is the YB25RKW01-5C-JB suitable for new product designs?

A: Yes. The YB25RKW01-5C-JB is classified as active product status, ensuring long-term availability and supply chain stability. It meets all current regulatory compliance requirements including ROHS3 and REACH.

Q: How do the termination styles affect compatibility?

A: The KB25RKW01-5C-JB uses solder lug termination exclusively. The YB25RKW01-5C-JB offers both solder and quick-connect 0.110" (2.8mm) termination options. Selection depends on the specific wiring harness and connection methodology of the target application.

Q: Are there any voltage or current limitations when substituting?

A: No. The YB25RKW01-5C-JB maintains the same voltage ratings (125V AC, 30V DC) and exceeds the current capacity of the original component. Applications operating within the original 1A specification will operate safely with the substitute.
