Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-5D05-JD qualifies as a direct functional substitute for the KB15CKW01-05-EB based on the following engineering criteria:

Compliance & Status: Both components maintain ROHS3 compliance and REACH unaffected status. The substitute part carries active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Electrical Compatibility: The substitute provides 3A current rating, exceeding the 1A requirement of the original part. Voltage ratings remain identical at 125V AC and 30V DC, maintaining full compatibility with existing circuit designs.

Mechanical & Operational Characteristics: Both switches feature identical SPDT circuit configuration, On-Mom switch function, and matching operating temperature range (-25°C to 50°C). The substitute demonstrates superior mechanical durability with 1,000,000 cycle life versus 100,000 cycles, and doubled electrical life at 100,000 cycles.

Installation Considerations: Panel cutout diameter increases from 12.30mm to 16.00mm. Panel modifications are required for mechanical accommodation. Termination options expand from solder lug to include quick connect capability.

Illumination Transition: The substitute transitions from incandescent yellow (5VAC) to LED amber (5VDC). This change requires verification of illumination voltage source compatibility in the host system.

Frequently Asked Questions (FAQ)

Q: Can YB15CKW01-5D05-JD directly replace KB15CKW01-05-EB without circuit modifications?

A: Electrical circuit compatibility is maintained. However, panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical panel modification. Illumination voltage changes from 5VAC to 5VDC, necessitating verification of the illumination power source in your system.

Q: What are the key differences in electrical performance?

A: The substitute provides 3A current rating compared to 1A in the original part. Both maintain 125V AC and 30V DC voltage ratings. Electrical life doubles from 50,000 to 100,000 cycles, and mechanical life increases from 100,000 to 1,000,000 cycles.

Q: Are both parts RoHS compliant?

A: Yes, both KB15CKW01-05-EB and YB15CKW01-5D05-JD are ROHS3 compliant with REACH unaffected status.

Q: What is the impact of changing from incandescent to LED illumination?

A: The illumination type changes from incandescent yellow to LED amber, and the voltage source changes from 5VAC to 5VDC. Color perception shifts from yellow to amber. LED illumination typically offers longer operational life and lower power consumption compared to incandescent technology.

Q: Does the substitute part support the same termination methods?

A: The original part uses solder lug termination. The substitute provides both solder and quick connect (0.110" / 2.8mm) termination options, offering greater installation flexibility.

Q: Why is the panel cutout diameter larger on the substitute part?

A: The YB series utilizes a 16.00mm panel cutout diameter compared to the KB series 12.30mm diameter. This is a mechanical design difference between the two product lines. Panel modification is required for installation.
