Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB26CKG01-5C-JC is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Voltage Ratings: 28V AC/DC operation is mandatory
• Current Rating: 0.4VA (AC/DC) capacity
• Illumination: Red LED at 1.9VDC nominal
• Mounting: Panel mount, front configuration
• Actuator: Round button design
• Temperature Range: -25°C to +50°C operational envelope
• Compliance: RoHS3 compliance required

The YB26CKG01-5C-JC qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in mechanical life rating (200,000 vs. 100,000 cycles), panel cutout dimensions, termination style, and product status do not preclude substitution when the primary functional requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The YB26CKG01-5C-JC is the direct equivalent for KB26CKG01-5C-JC applications. The substitute part maintains identical electrical specifications, voltage ratings, current capacity, and illumination characteristics. Both components are RoHS3 compliant and operate within the same temperature envelope.

The YB26CKG01-5C-JC carries active product status, ensuring continued availability and supply chain reliability compared to the obsolete KB26CKG01-5C-JC. The enhanced mechanical life rating (200,000 cycles versus 100,000 cycles) provides additional operational margin in high-cycle applications.

Physical integration requires verification of panel cutout dimensions: KB26CKG01-5C-JC specifies a 12.30mm circular cutout, while YB26CKG01-5C-JC requires 16.00mm. Termination style differs (solder lug versus solder/quick connect 0.110"), necessitating PCB layout and connector compatibility assessment during implementation.

Frequently Asked Questions (FAQ)

Q: Can YB26CKG01-5C-JC directly replace KB26CKG01-5C-JC in existing designs?

A: Electrical and functional compatibility is confirmed across all critical parameters. Physical integration requires panel cutout modification (12.30mm to 16.00mm) and termination style verification (solder lug to solder/quick connect 0.110").

Q: What are the key differences between these parts?

A: Primary differences are product status (obsolete vs. active), mechanical life rating (100,000 vs. 200,000 cycles), panel cutout diameter (12.30mm vs. 16.00mm), and termination style (solder lug vs. solder/quick connect). All electrical and illumination parameters are identical.

Q: Are both parts RoHS3 compliant?

A: Yes, both KB26CKG01-5C-JC and YB26CKG01-5C-JC are RoHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity).

Q: What voltage and current specifications must be matched for substitution?

A: Substitution requires 28V AC/DC voltage rating and 0.4VA current capacity. Both parts meet these specifications.

Q: Does the enhanced mechanical life of YB26CKG01-5C-JC affect electrical performance?

A: No. Mechanical life rating indicates cycle durability only. Electrical life (100,000 cycles) and all electrical parameters remain equivalent between both parts.

Q: What is the impact of different termination styles?

A: KB26CKG01-5C-JC uses solder lug termination; YB26CKG01-5C-JC uses solder and quick connect 0.110" (2.8mm) termination. PCB layout and connector compatibility must be evaluated for each application.
