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

Part Overview

The KB02KW01-5F-JB is an LED panel indicator manufactured by NKK Switches, classified as a green LED with clear lens transparency. This component is designed for panel-mount applications with a round cutout configuration. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where this indicator type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for LED panel indicators is determined by compatibility across the following critical parameters:

• Lamp color (green)
• Lens color (white)
• Panel cutout shape (round)
• Electrical ratings (voltage and current compatibility)
• Physical form factor (lens size and style)
• Compliance certifications (RoHS, REACH)

The YB02KW01-5F-JB meets the core functional requirements of lamp color, lens color, panel cutout shape, and lens style. However, this substitute introduces variations in lens transparency (diffused vs. clear), panel cutout dimensions (0.63" vs. 0.48"), lens size (15.00mm vs. 11.60mm), electrical ratings (2V/40mA vs. 2.1V/30mA), and termination style (quick connect vs. unspecified). These differences must be evaluated against specific application requirements before substitution.

Engineering Selection Recommendations

The YB02KW01-5F-JB is an active product from NKK Switches and maintains ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the obsolete KB02KW01-5F-JB. Selection of this substitute requires verification that:

• Panel cutout dimensions accommodate the larger 0.63" (16.00mm) opening required by the YB02KW01-5F-JB
• Lens size increase from 11.60mm to 15.00mm is acceptable for the application's visual and spatial requirements
• Lens transparency change from clear to diffused aligns with desired light distribution characteristics
• Electrical circuit design accommodates the voltage differential (2V vs. 2.1V) and increased current rating (40mA vs. 30mA)
• Termination interface compatibility with quick connect terminals is confirmed for the application

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5F-JB directly replace the KB02KW01-5F-JB without panel modifications?

A: No. The YB02KW01-5F-JB requires a larger panel cutout (0.63" vs. 0.48"). Panel drilling or modification is necessary for mechanical fit.

Q: What is the impact of changing from clear to diffused lens transparency?

A: Clear lenses provide direct light transmission with sharp visibility. Diffused lenses scatter light for broader viewing angles and softer appearance. Application requirements determine acceptability.

Q: Are the electrical ratings compatible?

A: The YB02KW01-5F-JB operates at 2V typical forward voltage versus 2.1V for the KB02KW01-5F-JB, with maximum current increased to 40mA versus 30mA. Circuit design must accommodate these specifications.

Q: What is the significance of the quick connect termination on the substitute?

A: The YB02KW01-5F-JB features 0.110" (2.8mm) quick connect terminals. Verify compatibility with existing wiring harnesses and connector interfaces in the application.

Q: Are both parts compliant with current regulations?

A: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Is the KB02KW01-5F-JB still available?

A: The KB02KW01-5F-JB is obsolete. The YB02KW01-5F-JB is listed as active with 1135 pieces in stock, providing supply continuity for new designs and replacements.
