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

Part Overview

The KB02KW01-5F-JF is a green LED panel indicator manufactured by NKK Switches, designed for applications requiring a 2.1V, 30mA illuminated status display with a 12.19mm round panel cutout. This component features a diffused green lens and solder lug termination. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-5F-JF is determined by the following critical parameters:

• Lamp and Lens Color: Both must be green to maintain visual indication consistency
• Lens Transparency: Diffused lens provides specific light diffusion characteristics; substitutes with clear lenses represent a functional change in light output distribution
• Electrical Ratings: Forward voltage (Vf) and maximum current (If) must be compatible with existing circuit design; the substitute operates at 2V/40mA versus the original 2.1V/30mA
• Panel Cutout Dimensions: The 12.19mm round cutout is a mechanical constraint; the substitute requires a 16.00mm cutout, necessitating panel modification
• Termination Style: The original uses solder lug termination; the substitute uses quick connect 0.110" (2.8mm) termination, requiring different connection methodology
• Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status

The YB02KW01-5F-JF represents a functional equivalent in lamp color and lens style but introduces mechanical and electrical differences that require design consideration.

Parameter Comparison

Engineering Selection Recommendations

The YB02KW01-5F-JF is an active product from NKK Switches and maintains equivalent regulatory compliance (ROHS3, REACH unaffected) to the obsolete KB02KW01-5F-JF. Selection of this substitute requires evaluation of the following design impacts:

• Mechanical Integration: Panel cutout diameter increases from 12.19mm to 16.00mm; existing panel designs require modification or replacement
• Electrical Compatibility: Forward voltage decreases from 2.1V to 2V (0.1V reduction); maximum current increases from 30mA to 40mA; circuit design must accommodate these parameter shifts
• Termination Change: Transition from solder lug to quick connect 0.110" (2.8mm) termination requires different connection hardware and assembly methodology
• Optical Characteristics: Lens transparency changes from diffused to clear, altering light distribution and perceived brightness

The substitute part is suitable for new designs or retrofit applications where mechanical panel modification and termination method changes are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5F-JF be used as a direct drop-in replacement for the KB02KW01-5F-JF?

A: No. The substitute requires panel cutout modification (12.19mm to 16.00mm), termination method change (solder lug to quick connect), and electrical parameter adjustment. Direct substitution without design modification is not possible.

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

A: The clear lens of the YB02KW01-5F-JF provides different light diffusion characteristics compared to the diffused lens of the original part. This affects light distribution and perceived brightness in the application.

Q: Are the electrical parameters compatible with existing circuits?

A: The forward voltage decreases by 0.1V (2.1V to 2V) and maximum current increases by 10mA (30mA to 40mA). Circuit design must be verified to ensure these parameter changes do not affect performance or reliability.

Q: What termination method does the substitute use?

A: The YB02KW01-5F-JF uses quick connect 0.110" (2.8mm) termination, replacing the solder lug termination of the original part. Different connection hardware is required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the KB02KW01-5F-JF and YB02KW01-5F-JF are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status.

Q: What is the availability status of each part?

A: The KB02KW01-5F-JF is obsolete with 990 pieces in stock. The YB02KW01-5F-JF is active with 653 pieces in stock, providing ongoing supply availability.
