Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB15SKW01-05-CB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Voltage rating (125V AC minimum)
• Mounting type (Panel Mount, Front)
• Operating temperature range (-25°C to 50°C)
• Panel cutout dimensions (circular configuration)
• RoHS3 compliance status

Allowable Variation Parameters:

• Current rating (substitute may exceed 1A specification)
• Illumination technology (incandescent to LED conversion acceptable)
• Illumination voltage (5VAC to 5VDC conversion acceptable)
• Termination style (solder lug to solder/quick connect conversion acceptable)
• Mechanical and electrical life cycles (higher values acceptable)

The YB15SKW01-5C05-JC meets all mandatory compatibility criteria while providing enhanced electrical characteristics and modern LED illumination technology.

Parameter Comparison

Engineering Selection Recommendations

The YB15SKW01-5C05-JC is a direct functional substitute for the KB15SKW01-05-CB based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical SPDT circuit configuration, 125V AC voltage rating, and 30V DC voltage rating. The substitute's 3A current rating exceeds the original 1A specification, providing enhanced capacity for the same application envelope.

Mechanical Compatibility: Panel mount front installation is preserved. The substitute features a larger 16.00mm panel cutout diameter compared to the original 12.30mm specification, requiring panel modification for direct replacement.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Product Status Advantage: The substitute is classified as active product status, ensuring long-term availability and supply chain continuity compared to the obsolete original component.

Illumination Technology: The transition from incandescent to LED illumination provides improved reliability and reduced power consumption. Illumination voltage conversion from 5VAC to 5VDC requires circuit-level evaluation for compatibility with existing power supply infrastructure.

Frequently Asked Questions (FAQ)

Q: Can the YB15SKW01-5C05-JC directly replace the KB15SKW01-05-CB without panel modification?

A: No. The substitute requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Physical panel modification is necessary for installation.

Q: Are the voltage ratings identical between the two components?

A: Yes. Both components are rated for 125V AC and 30V DC operation, maintaining electrical compatibility within the original design envelope.

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

A: The illumination voltage changes from 5VAC to 5VDC. Circuit-level verification is required to confirm compatibility with existing illumination power supply configuration.

Q: Does the higher current rating of the substitute affect compatibility?

A: No. The 3A rating of the substitute exceeds the original 1A requirement. The substitute is suitable for applications requiring the original 1A specification.

Q: Are both components RoHS3 compliant?

A: Yes. Both the KB15SKW01-05-CB and YB15SKW01-5C05-JC maintain ROHS3 compliance status.

Q: What is the significance of the product status difference?

A: The original component is obsolete, limiting future availability. The substitute is active product status, ensuring continued supply chain access and manufacturer support.

Q: How do the mechanical life specifications compare?

A: The substitute provides 1,000,000 mechanical cycles compared to the original 100,000 cycles, representing a 10-fold improvement in mechanical durability.
