Key Parameters

Substitute Part Grouping Explanation

The YB25CKW01-6B-JB qualifies as a substitute for the KB25CKW01-6B-JB based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-Mom
• Voltage rating: 125V AC / 30V DC
• Mounting type: Panel Mount, Front
• Illumination type: LED, White
• Illumination voltage: 3.3VDC
• Actuator type: Round, Button
• Operating temperature range: -25°C to 50°C
• RoHS compliance: ROHS3 Compliant
• Termination compatibility: Both use solder-based connections

Substitution Basis: The YB25CKW01-6B-JB maintains functional equivalence in circuit topology, voltage specifications, and illumination characteristics. The substitute part is manufactured by the same supplier (NKK Switches) and operates within identical environmental parameters. The primary differences—increased current rating (3A vs 1A), enhanced mechanical life (1,000,000 vs 100,000 cycles), and improved electrical life (100,000 vs 50,000 cycles)—represent performance enhancements rather than incompatibilities. The substitute part's active product status ensures ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The YB25CKW01-6B-JB is suitable as a direct substitute for the KB25CKW01-6B-JB in applications where the electrical and mechanical specifications align with system requirements. Both components maintain ROHS3 compliance and identical voltage/temperature operating parameters, ensuring regulatory and environmental compatibility.

The substitute part's active product status provides assurance of continued manufacturing support and supply chain availability, addressing the obsolescence of the original component. The enhanced current rating (3A) and extended mechanical/electrical life cycles of the substitute represent performance improvements that do not compromise backward compatibility in circuits designed for the original 1A specification.

Physical integration requires consideration of the panel cutout diameter difference: the substitute requires a 16.00mm circular opening compared to the original 12.30mm specification. Termination compatibility must be evaluated based on circuit board design; the substitute offers both solder lug and quick-connect options, providing flexibility for different assembly approaches.

Frequently Asked Questions (FAQ)

Q: Can the YB25CKW01-6B-JB directly replace the KB25CKW01-6B-JB in existing designs?

A: Electrical and functional compatibility is confirmed across all critical parameters: DPDT circuit, On-Mom function, 125V AC / 30V DC ratings, and LED illumination specifications. Physical integration requires panel cutout modification from 12.30mm to 16.00mm diameter. Termination options differ; the substitute provides solder and quick-connect alternatives to the original solder lug configuration.

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

A: The substitute part provides enhanced performance specifications: current rating increased from 1A to 3A, mechanical life extended from 100,000 to 1,000,000 cycles, and electrical life doubled from 50,000 to 100,000 cycles. The substitute maintains active product status versus the obsolete classification of the original. Panel cutout diameter increases from 12.30mm to 16.00mm.

Q: Are both components RoHS compliant?

A: Yes, both the KB25CKW01-6B-JB and YB25CKW01-6B-JB are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What packaging differences exist between these parts?

A: The original KB25CKW01-6B-JB is supplied with standard packaging. The substitute YB25CKW01-6B-JB is packaged in trays, which may affect inventory management and assembly line integration procedures.

Q: Does the increased current rating of the substitute create any compatibility issues?

A: No. The 3A rating of the substitute represents a performance enhancement. Circuits designed for the original 1A specification will operate within safe parameters when using the substitute, as the higher current capacity does not impose additional electrical demands on the circuit.

Q: What termination options are available with the substitute part?

A: The YB25CKW01-6B-JB offers both solder and quick-connect (0.110" / 2.8mm) termination styles, providing flexibility compared to the original solder lug configuration. Circuit board design and assembly processes should determine the appropriate termination selection.
