Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB01KW01-5F-JB is determined by the following critical parameters:

• Lamp Color: Green (required match)
• Type: LED (required match)
• Forward Voltage (Vf): 2.1V nominal (acceptable range: 1.9V to 2.1V for circuit compatibility)
• Maximum Current (If): 30mA nominal (acceptable range: 30mA to 40mA for driver circuit tolerance)
• Panel Cutout Shape: Round (required match for mechanical fit)
• Lens Style: Square with Flat Top (required match for aesthetic and functional consistency)
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected (required match)

The YB01KW01-5F-JB qualifies as a substitute based on matching lamp color (green), LED type, compatible voltage and current ratings within acceptable operating ranges, identical panel cutout shape, matching lens style, and equivalent regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The YB01KW01-5F-JB is an active product from NKK Switches and maintains ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the obsolete KB01KW01-5F-JB.

Electrical compatibility is established through forward voltage and current ratings within acceptable operating ranges. The YB01KW01-5F-JB operates at 1.9V (0.2V lower) with a maximum current rating of 40mA (10mA higher), both parameters remaining within typical circuit design tolerances for LED driver circuits.

Mechanical considerations require evaluation: the YB01KW01-5F-JB requires a larger panel cutout (0.63" versus 0.48") and features a larger lens size (15.00mm versus 11.60mm). Panel modification may be necessary for physical installation. The substitute features a diffused lens with green coloring compared to the clear white lens of the original part, resulting in different light transmission and appearance characteristics.

The YB01KW01-5F-JB includes Quick Connect termination (0.110" / 2.8mm), whereas the original part termination style is not specified. Connector compatibility must be verified against the application circuit.

Frequently Asked Questions (FAQ)

Q: Can the YB01KW01-5F-JB directly replace the KB01KW01-5F-JB without circuit modification?

A: Electrical substitution is feasible due to compatible voltage and current ratings. However, panel cutout dimensions differ (0.48" versus 0.63"), requiring mechanical modification to the mounting panel. Termination style differences must also be evaluated for connector compatibility.

Q: What are the key differences in optical performance between these parts?

A: The KB01KW01-5F-JB features a clear white lens (11.60mm), while the YB01KW01-5F-JB has a diffused green lens (15.00mm). These differences affect light transmission characteristics, brightness distribution, and visual appearance. The diffused lens provides wider light dispersion compared to the clear lens.

Q: Are both parts compliant with current regulatory standards?

A: Both the KB01KW01-5F-JB and YB01KW01-5F-JB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

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

A: The KB01KW01-5F-JB is obsolete, indicating discontinued production and limited availability. The YB01KW01-5F-JB is active, ensuring ongoing availability and continued manufacturer support for future procurement.

Q: How do the current ratings affect circuit design?

A: The KB01KW01-5F-JB is rated for 30mA maximum current, while the YB01KW01-5F-JB is rated for 40mA. Existing circuits designed for 30mA operation remain compatible with the substitute. Circuits operating near the 30mA limit benefit from the higher 40mA rating of the substitute part.
