LED Panel Indicator KB02KW01-5F12-JB Equivalent & Substitute Parts

Part Overview

The KB02KW01-5F12-JB is an LED panel indicator manufactured by NKK Switches, designed for 12V DC applications with a 20mA current rating. This component features a green diffused lens with a round panel cutout measuring 0.48" (12.19mm) and employs solder lug termination. The product is classified as obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-5F12-JB is determined by alignment of the following critical parameters:

• Voltage rating (12V)
• Current rating (20mA)
• Lamp color (Green)
• Lens transparency (Diffused)
• Lens style (Round with Flat Top)
• Panel cutout shape (Round)
• Termination compatibility with circuit design

The YB02KW01-5F12-JB qualifies as a substitute based on matching voltage, current, lamp color, lens transparency, and lens style. However, differences exist in panel cutout dimensions, lens size, lens color, ratings type, and termination style. These differences require evaluation for mechanical fit and electrical integration in the target application.

Parameter Comparison

Engineering Selection Recommendations

The YB02KW01-5F12-JB is an active product from NKK Switches and maintains ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the obsolete KB02KW01-5F12-JB. Both components share identical voltage, current, lamp color, and lens transparency specifications.

Selection of the YB02KW01-5F12-JB as a substitute requires verification of the following conditions:

• Panel cutout dimensions must accommodate the larger 0.63" (16.00mm) opening required by the substitute part
• Mechanical mounting must be compatible with the increased lens diameter of 15.00mm
• Termination method must be compatible with circuit design; the substitute uses quick connect terminals rather than solder lugs
• Application voltage source must support AC ratings, as the substitute is rated for AC operation

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5F12-JB directly replace the KB02KW01-5F12-JB without modification?

A: Direct replacement is not possible without mechanical and electrical modifications. The substitute part requires a larger panel cutout (0.63" vs 0.48"), has a larger lens diameter (15.00mm vs 11.60mm), uses quick connect termination instead of solder lugs, and is rated for AC operation rather than DC. Panel drilling or enlargement and termination rewiring are necessary.

Q: What are the key electrical compatibility factors?

A: Both parts operate at 12V with 20mA current draw and feature green diffused lenses. The primary electrical difference is the ratings type: the original part is DC-rated while the substitute is AC-rated. Verify that your application voltage source matches the substitute's AC rating requirement.

Q: Are there mechanical fit considerations?

A: Yes. The substitute part has a significantly larger panel cutout requirement (0.63" diameter vs 0.48") and a larger lens diameter (15.00mm vs 11.60mm). Existing panel cutouts designed for the KB02KW01-5F12-JB will not accommodate the YB02KW01-5F12-JB without enlargement.

Q: What is the difference between solder lug and quick connect termination?

A: Solder lug termination on the KB02KW01-5F12-JB requires direct soldering to circuit board traces or wiring. Quick connect termination on the YB02KW01-5F12-JB uses 0.110" (2.8mm) spade connectors for push-on connection. Circuit design must be adapted to accommodate the termination method change.

Q: Why is the lens color different between the two parts?

A: The KB02KW01-5F12-JB has a green lens, while the YB02KW01-5F12-JB has a white lens. Both produce green light output due to the green lamp color. The white lens may produce different light diffusion and intensity characteristics compared to the green lens.

Q: Are both parts compliant with current regulations?

A: Yes. Both the KB02KW01-5F12-JB and YB02KW01-5F12-JB are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
