Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15CKG01-12-JC is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• SPDT circuit configuration (mandatory)
• 0.4VA current rating at 28V AC/DC (mandatory)
• On-Momentary switch function (mandatory)
• Operating temperature range -25°C to 50°C (mandatory)

Mechanical Compatibility Requirements:

• Panel mount, front-facing installation (mandatory)
• Round button actuator type (mandatory)
• Red illumination color (mandatory)

Regulatory & Compliance Requirements:

• ROHS3 compliance (mandatory)
• REACH unaffected status (mandatory)

The substitute part YB15CKG01-5C12-JC meets all electrical and mechanical compatibility criteria. However, differences exist in illumination technology (LED vs. incandescent), termination style (Quick Connect vs. Solder Lug), panel cutout diameter (16.00mm vs. 12.30mm), and mechanical life rating (1,000,000 vs. 100,000 cycles). These differences require engineering evaluation based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB15CKG01-5C12-JC qualifies as a functional substitute based on electrical and mechanical parameter equivalence. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

Selection between the main part and substitute requires consideration of application-specific factors:

Panel Integration: The substitute part requires a 16.00mm panel cutout diameter compared to the original 12.30mm specification. Panel modifications may be necessary for mechanical fit.

Illumination Technology: The substitute employs LED illumination at 12VDC versus incandescent illumination at 12VAC in the original. Existing illumination power supply circuits must be evaluated for voltage and current compatibility.

Termination Compatibility: The substitute offers Quick Connect termination in addition to solder connection, providing flexibility in installation methods. Original designs using solder lug termination require assessment of connection point compatibility.

Mechanical Durability: The substitute provides extended mechanical life (1,000,000 cycles) compared to the original (100,000 cycles), offering improved longevity in high-cycle applications.

The active product status of the substitute ensures ongoing availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can YB15CKG01-5C12-JC be used as a direct replacement for KB15CKG01-12-JC?

A: Electrical and functional compatibility is confirmed. However, panel cutout diameter differences (16.00mm vs. 12.30mm) and illumination voltage differences (12VDC vs. 12VAC) require mechanical and electrical assessment before implementation.

Q: What are the key differences between these two components?

A: Primary differences include illumination technology (LED vs. incandescent), illumination voltage (12VDC vs. 12VAC), termination options (Quick Connect addition), panel cutout diameter (16.00mm vs. 12.30mm), and mechanical life rating (1,000,000 vs. 100,000 cycles).

Q: Are both components RoHS compliant?

A: Yes, both KB15CKG01-12-JC and YB15CKG01-5C12-JC are ROHS3 compliant and REACH unaffected.

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

A: KB15CKG01-12-JC is classified as obsolete, indicating discontinued manufacturing. YB15CKG01-5C12-JC maintains active status, ensuring continued availability and supply chain support.

Q: Does the panel cutout diameter difference affect electrical performance?

A: Panel cutout diameter is a mechanical specification affecting physical installation only. Electrical performance remains equivalent across both components.

Q: Can the illumination voltage difference be accommodated in existing designs?

A: Illumination voltage conversion from 12VAC to 12VDC requires circuit modification. Power supply compatibility must be verified before substitution.
