Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKW01-5C-JC is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Voltage ratings (125V AC / 30V DC minimum)
• Mounting type (Panel Mount, Front)
• Actuator type (Round, Button)
• Illumination type and color (LED, Red)
• Illumination voltage (1.9 VDC)
• Operating temperature range (-25°C ~ 50°C)

Allowable Variation Parameters:

• Current rating (may be equal or higher)
• Mechanical and electrical life ratings (may be equal or higher)
• Panel cutout diameter (mechanical accommodation required)
• Termination style (application-dependent)
• Product status (active preferred for new applications)

The YB15CKW01-5C-JC qualifies as a substitute based on matching all mandatory parameters while providing enhanced performance specifications in current rating, mechanical life, and electrical life.

Engineering Selection Recommendations

The YB15CKW01-5C-JC is a qualified substitute for the KB15CKW01-5C-JC based on functional equivalence and enhanced performance characteristics. Key considerations for selection:

Product Status: The substitute part maintains active product status with NKK Switches, ensuring continued availability and supply chain reliability compared to the obsolete main part.

Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Performance Enhancement: The substitute provides superior mechanical life (1,000,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), supporting extended operational requirements.

Current Rating: The substitute accommodates higher current loads (3A versus 1A), providing design margin for applications requiring increased switching capacity.

Mechanical Integration: Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical accommodation in panel design. Termination style modification from solder lug to solder with quick connect option may require circuit board layout adjustment.

Frequently Asked Questions (FAQ)

Q: Can YB15CKW01-5C-JC directly replace KB15CKW01-5C-JC without modification?

A: Functional substitution is supported. However, mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination style differs (solder lug versus solder/quick connect), necessitating circuit board connection method evaluation.

Q: What are the key compatibility criteria for this substitution?

A: SPDT circuit configuration, On-Mom switch function, 125V AC / 30V DC voltage ratings, panel-mount front orientation, round button actuator, red LED illumination at 1.9VDC, and -25°C to 50°C operating temperature range must all be maintained.

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

A: No. The 3A rating of YB15CKW01-5C-JC is backward compatible with applications designed for 1A operation. The substitute accommodates the original design requirements while providing additional capacity margin.

Q: Are there packaging differences between these parts?

A: The main part KB15CKW01-5C-JC uses standard packaging, while the substitute YB15CKW01-5C-JC is supplied in tray packaging. This affects handling and storage procedures but does not impact functional performance.

Q: What mechanical modifications are required for panel integration?

A: The panel cutout diameter must be increased from 12.30mm to 16.00mm to accommodate the larger actuator assembly of the YB15CKW01-5C-JC. Verify panel material thickness compatibility with the substitute's mounting requirements.
