KB02KW01-5C12-JC LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The KB02KW01-5C12-JC is an LED panel indicator manufactured by NKK Switches, classified as a red LED with clear lens transparency designed for 12V AC applications at 20mA. This component is currently listed as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part features a round panel cutout of 0.48" (12.19mm) and an 11.60mm diameter round lens with flat top styling.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-5C12-JC is determined by the following critical parameters:

• Electrical Compatibility: Voltage (12V), current (20mA), and ratings type (AC/DC)
• Optical Properties: Lamp color (red) and lens color (red)
• Mechanical Fit: Panel cutout shape (round) and cutout dimensions
• Lens Characteristics: Lens size, lens style, and lens transparency

The YB02KW01-5C12-JC qualifies as a substitute based on matching voltage, current, lamp color, lens color, lens style, and panel cutout shape. However, differences exist in lens transparency (diffused vs. clear), panel cutout dimensions (0.63" vs. 0.48"), lens size (16.00mm vs. 11.60mm), ratings type (DC vs. AC), and termination style (quick connect vs. unspecified). These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB02KW01-5C12-JC is an active product from NKK Switches and maintains ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the obsolete KB02KW01-5C12-JC. Selection of this substitute requires evaluation of the following factors:

• Panel Cutout Compatibility: The substitute requires a 0.63" (16.00mm) round cutout versus the original 0.48" (12.19mm). Panel modification may be necessary.
• Lens Transparency Difference: The substitute features diffused lens transparency compared to the clear lens of the original. This affects light diffusion characteristics and may impact visual indication clarity.
• Ratings Type Difference: The substitute is rated for DC operation while the original is rated for AC. Application voltage source type must be confirmed.
• Termination Interface: The substitute includes quick connect termination (0.110" / 2.8mm), whereas the original termination style is not specified. Wiring interface compatibility must be verified.

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5C12-JC directly replace the KB02KW01-5C12-JC without panel modification?

A: No. The YB02KW01-5C12-JC requires a 0.63" (16.00mm) panel cutout, while the KB02KW01-5C12-JC uses a 0.48" (12.19mm) cutout. Panel drilling or modification is required for mechanical fit.

Q: What is the impact of the lens transparency difference between clear and diffused?

A: Clear lens provides direct light transmission with minimal diffusion, while diffused lens scatters light over a wider area. The diffused lens of the substitute will produce a broader light distribution pattern compared to the original clear lens.

Q: Are both parts suitable for the same voltage source?

A: No. The KB02KW01-5C12-JC is rated for 12V AC, while the YB02KW01-5C12-JC is rated for 12V DC. The application voltage source type must match the part rating.

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

A: The YB02KW01-5C12-JC features quick connect termination (0.110" / 2.8mm), which differs from the unspecified termination of the original. Wiring harness compatibility must be verified before substitution.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the KB02KW01-5C12-JC and YB02KW01-5C12-JC are ROHS3 compliant and REACH unaffected, meeting current regulatory standards.
