Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-12-CB is determined by the following critical parameters:

• Voltage Rating: 12V DC operation
• Lamp Color and Lens Color: Red indication
• Lens Transparency: Diffused optical characteristics
• Panel Cutout Shape: Round configuration
• Lens Style: Round with Flat Top geometry
• Regulatory Compliance: ROHS3 and REACH status

The YB02KW01-5C12-JC qualifies as a substitute based on matching voltage rating, lamp color, lens color, lens transparency, panel cutout shape, and lens style. This substitute maintains functional equivalence for red 12V panel indication applications while meeting the same regulatory compliance standards.

Parameter Comparison

Engineering Selection Recommendations

The YB02KW01-5C12-JC is an active product substitute for the obsolete KB02KW01-12-CB. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new implementations and legacy system replacements.

Key considerations for selection:

• The substitute transitions from incandescent to LED technology, resulting in reduced current consumption (20mA versus 60mA)
• Panel cutout dimensions differ: the substitute requires a 0.63" (16.00mm) round opening versus the original 0.48" (12.19mm)
• Termination changes from solder lug to quick connect 0.110" (2.8mm) connector
• Both maintain 12V DC voltage rating and red diffused lens characteristics

Selection of the YB02KW01-5C12-JC requires mechanical panel modification to accommodate the larger cutout diameter and electrical interface adaptation for the quick connect termination.

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5C12-JC directly replace the KB02KW01-12-CB without modification?

A: Direct replacement requires mechanical and electrical adaptation. The substitute has a larger panel cutout diameter (16.00mm versus 12.19mm) and uses quick connect termination instead of solder lug. Panel drilling or enlargement and connector interface changes are necessary.

Q: What is the primary functional difference between these components?

A: The main part uses incandescent lamp technology, while the substitute uses LED technology. Both provide red 12V panel indication with diffused lens characteristics. The LED substitute operates at lower current (20mA versus 60mA).

Q: Are both components compliant with current regulatory standards?

A: Yes. Both the KB02KW01-12-CB and YB02KW01-5C12-JC are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: What termination options are available?

A: The original part uses solder lug termination for direct PCB soldering. The substitute uses quick connect 0.110" (2.8mm) termination, requiring a mating connector interface.

Q: How do the lens sizes compare?

A: The original lens measures 11.60mm diameter, while the substitute lens measures 16.00mm diameter. This difference affects panel cutout requirements and visual presentation.
