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

Part Overview

The KB02KW01-5C-JC is a red LED panel indicator manufactured by NKK Switches, designed for applications requiring a 1.9V, 30mA illuminated status display with a diffused lens. This component features a round panel cutout (0.48" / 12.19mm) and solder lug termination. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-5C-JC is determined by the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf) of 1.9V
• Red lamp color and red lens color
• Current rating compatibility (original: 30mA maximum)

Mechanical Compatibility:

• Round panel cutout shape
• Panel cutout diameter tolerance (original: 0.48" / 12.19mm)
• Lens style (round with flat top)
• Termination method compatibility

Regulatory & Environmental:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• REACH unaffected status

The substitute part YB02KW01-5C-JC maintains electrical equivalence (1.9V red LED) and mechanical form factor compatibility while offering active product status and enhanced current rating (40mA). Mechanical integration requires evaluation of panel cutout dimensions and termination style differences.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Electrical Equivalence): The YB02KW01-5C-JC maintains identical forward voltage (1.9V) and red LED color specification, ensuring electrical compatibility with existing circuit designs. Both components meet ROHS3 compliance and REACH unaffected requirements.

Mechanical Integration Considerations: The substitute part requires panel cutout modification due to increased diameter (0.63" vs. 0.48"). The lens size increase (15.00mm vs. 11.60mm) affects visual appearance and light distribution characteristics. The lens transparency change from diffused to clear alters the optical output profile.

Termination Method Change: The KB02KW01-5C-JC uses solder lug termination, while the YB02KW01-5C-JC uses quick connect terminals (0.110" / 2.8mm). Circuit board modifications or connector adaptation is required for substitution.

Current Rating Upgrade: The substitute part supports 40mA maximum current versus 30mA for the original, providing design margin for existing applications operating within the original 30mA specification.

Product Status Advantage: The YB02KW01-5C-JC is classified as active product status, ensuring long-term availability and supply chain continuity compared to the obsolete KB02KW01-5C-JC.

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5C-JC be used as a direct electrical replacement? A: Yes, both components share identical forward voltage (1.9V) and red LED color specification. Electrical circuit compatibility is maintained. However, mechanical integration and termination method differences require design evaluation.

Q: What are the key differences between these parts? A: The primary differences are panel cutout diameter (0.48" vs. 0.63"), lens size (11.60mm vs. 15.00mm), lens transparency (diffused vs. clear), termination style (solder lug vs. quick connect), and current rating (30mA vs. 40mA).

Q: Does the lens transparency change affect performance? A: The change from diffused to clear lens alters light distribution and brightness perception. The diffused lens provides wider viewing angle with softer light output, while the clear lens produces more concentrated, brighter illumination.

Q: What modifications are needed for panel integration? A: The panel cutout must be enlarged from 0.48" to 0.63" diameter to accommodate the larger lens assembly of the YB02KW01-5C-JC.

Q: Are both parts RoHS and REACH compliant? A: Yes, both KB02KW01-5C-JC and YB02KW01-5C-JC are ROHS3 compliant and REACH unaffected.

Q: What is the impact of the termination style change? A: The original part uses solder lug termination for direct PCB soldering. The substitute uses quick connect terminals (0.110" / 2.8mm), requiring either connector adaptation or circuit board redesign for compatibility.

Q: Is the higher current rating (40mA) of the substitute a concern? A: No. The substitute's 40mA rating is a capability increase. Existing designs operating at 30mA or below remain fully compatible and benefit from additional design margin.
