Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-01-JC requires evaluation based on the following critical parameters:

Functional Equivalence Criteria:

• Lamp color and lens color (red)
• Panel cutout shape and dimensions (round, 0.48" / 12.19mm)
• Lens style (round with flat top)
• Regulatory compliance (RoHS3, REACH Unaffected)

Electrical Compatibility Considerations: The KB02KW01-01-JC operates at 110V with 1.5mA current draw. Substitute parts must accommodate the electrical characteristics of the host circuit while maintaining the same visual indication function and physical form factor.

Identified Substitute: YB02KW01-5C-JC (NKK Switches) — An active LED panel indicator with red lamp and lens, round panel cutout, and equivalent mechanical mounting characteristics. This substitute represents a technology transition from neon to LED while preserving the core functional requirements of the application.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The KB02KW01-01-JC is classified as obsolete. The YB02KW01-5C-JC is an active product, ensuring ongoing availability and supply chain continuity for new designs and maintenance applications.

Regulatory Compliance: Both the main part and substitute meet ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements for electronic component deployment.

Substitution Feasibility: Selection of YB02KW01-5C-JC as a substitute requires circuit-level evaluation due to differences in voltage rating (110V vs. 1.9V), current consumption (1.5mA vs. 40mA), panel cutout dimensions (0.48" vs. 0.63"), and termination style (solder lug vs. quick connect). These differences necessitate mechanical and electrical integration assessment within the host system.

Frequently Asked Questions (FAQ)

Q: Can YB02KW01-5C-JC directly replace KB02KW01-01-JC without circuit modifications?

A: No. The substitute part operates at significantly different electrical parameters (1.9V vs. 110V) and requires different termination connections (quick connect vs. solder lug). Circuit redesign and power supply adjustment are necessary.

Q: What are the mechanical compatibility considerations?

A: The panel cutout dimensions differ (0.48" vs. 0.63"). The substitute requires a larger panel opening. Lens size also increases from 11.60mm to 15.00mm diameter. Panel modification may be required.

Q: Are both parts compliant with current environmental standards?

A: Yes. Both KB02KW01-01-JC and YB02KW01-5C-JC are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements.

Q: Why is the lens transparency different between the main part and substitute?

A: The KB02KW01-01-JC features a diffused lens, while YB02KW01-5C-JC has a clear lens. This affects light diffusion characteristics and may impact visual appearance in the application.

Q: What is the primary reason to consider substitution?

A: The KB02KW01-01-JC is obsolete. YB02KW01-5C-JC is an active product offering equivalent functional indication with modern LED technology and assured supply availability.
