Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKW01-12-CB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Voltage rating (125V AC minimum)
• Mounting type (Panel Mount, Front)
• Actuator type (Round Button)
• Illumination color (Red)
• Operating temperature range (-25°C to 50°C)
• Termination compatibility with solder lug connections

Allowable Variation Parameters:

• Current rating (may exceed 1A specification)
• Mechanical and electrical life cycles (may exceed minimum values)
• Panel cutout diameter (mechanical accommodation required)
• Illumination technology (incandescent to LED transition acceptable with voltage compatibility)
• Illumination voltage (12V nominal, AC or DC acceptable)

The YB15CKW01-5C12-JC meets these substitution criteria while offering enhanced performance characteristics including higher current capacity (3A), extended mechanical life (1,000,000 cycles), and LED illumination technology.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKW01-5C12-JC is a functionally equivalent substitute for the obsolete KB15CKW01-12-CB. Both components maintain identical electrical specifications for circuit configuration, voltage ratings, and operating temperature range. The substitute part offers superior performance through increased current capacity (3A versus 1A) and extended mechanical life (1,000,000 versus 100,000 cycles), providing enhanced reliability for applications requiring this switch type.

Key considerations for implementation:

Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Illumination Technology Transition: The substitute employs LED illumination at 12 VDC in place of incandescent illumination at 12 VAC. This transition requires verification of illumination voltage supply compatibility within the host system. LED technology provides extended operational life and reduced power consumption compared to incandescent sources.

Mechanical Integration: The substitute part requires a larger panel cutout diameter (16.00mm versus 12.30mm). Panel modification or redesign may be necessary for direct mechanical substitution.

Termination Compatibility: The substitute provides both solder and quick-connect termination options (0.110" / 2.8mm), offering greater flexibility compared to the solder lug termination of the original part.

Product Availability: The substitute part maintains active product status with confirmed inventory availability, ensuring supply chain continuity for ongoing production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the YB15CKW01-5C12-JC directly replace the KB15CKW01-12-CB without modifications?

A: Electrical substitution is direct. Mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Illumination voltage supply must be verified for 12 VDC compatibility (substitute) versus 12 VAC (original).

Q: What is the impact of the current rating increase from 1A to 3A?

A: The higher current rating of the substitute part provides enhanced capacity for applications requiring greater switching current. This represents an upward-compatible specification change with no negative impact on systems designed for 1A operation.

Q: Are there compatibility concerns with the LED illumination change?

A: The illumination technology transition from incandescent to LED requires confirmation that the host system provides 12 VDC supply voltage. If the original system supplies only 12 VAC, a power supply modification is necessary. LED illumination offers extended service life and reduced power consumption.

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

A: The YB15CKW01-5C12-JC provides dual termination capability: solder connection and quick-connect terminals (0.110" / 2.8mm). This offers greater installation flexibility compared to the solder lug termination of the original part.

Q: Does the larger panel cutout diameter affect functional performance?

A: Panel cutout diameter is a mechanical accommodation parameter only. The larger cutout (16.00mm versus 12.30mm) does not affect electrical performance or switch function. Panel modification is required for physical installation.

Q: Are both parts compliant with current regulatory standards?

A: Both the KB15CKW01-12-CB and YB15CKW01-5C12-JC maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.
