KB02KW01-5C-JB LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The KB02KW01-5C-JB is a red LED panel indicator manufactured by NKK Switches, designed for applications requiring a 1.9V, 30mA illuminated status display with solder lug termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. This reference provides engineering-grade substitution guidance based on electrical and mechanical compatibility parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB02KW01-5C-JB is determined by the following critical parameters:

• Lamp color and lens color (Red)
• Lens transparency (Diffused)
• Forward voltage rating (1.9V)
• Panel cutout shape (Round)
• Lens style (Round with Flat Top)
• Compliance certifications (ROHS3, REACH Unaffected)

The YB02KW01-5C-JB qualifies as a functional substitute based on matching electrical characteristics (1.9V forward voltage, red diffused lens) and mechanical compatibility (round panel cutout, round flat-top lens style). Differences in maximum current rating (40mA vs. 30mA), panel cutout dimensions, lens diameter, and termination style (quick connect vs. solder lug) represent design variations that may require circuit and mechanical redesign considerations.

Parameter Comparison

Engineering Selection Recommendations

The YB02KW01-5C-JB is an active product from the same manufacturer with matching electrical specifications (1.9V, red diffused lens) and mechanical form factor (round flat-top lens). Selection of this substitute requires evaluation of the following factors:

• Panel cutout diameter increase from 12.19mm to 16.00mm necessitates mechanical redesign of the mounting panel
• Lens diameter increase from 11.60mm to 16.00mm affects visual appearance and light distribution characteristics
• Termination change from solder lug to quick connect (0.110" / 2.8mm) requires circuit board redesign and connector compatibility assessment
• Maximum current rating increase from 30mA to 40mA provides additional operational margin within the same forward voltage specification
• Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5C-JB be used as a direct replacement for the KB02KW01-5C-JB without modifications?

A: No. While electrical specifications are compatible, the larger panel cutout diameter (16.00mm vs. 12.19mm), increased lens size (16.00mm vs. 11.60mm), and different termination style (quick connect vs. solder lug) require mechanical and electrical redesign.

Q: What is the significance of the current rating difference (30mA vs. 40mA)?

A: The YB02KW01-5C-JB supports higher maximum current at the same forward voltage. Existing circuits designed for 30mA operation remain compatible, as the substitute can operate at or below the original current specification.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status.

Q: What are the primary design considerations when switching from KB02KW01-5C-JB to YB02KW01-5C-JB?

A: Primary considerations are panel cutout enlargement, lens diameter increase affecting visual presentation, and termination method change requiring connector specification and circuit board layout modification.

Q: Is the YB02KW01-5C-JB the only available substitute?

A: Based on provided data, YB02KW01-5C-JB is the documented substitute. The YB02 series includes additional variants (YB02WKW01-5C-JB, YB02WKW01-5C-JC) that may offer alternative configurations.
