KB02KW01-12-FF Equivalent & Substitute Parts

Part Overview

The KB02KW01-12-FF is an incandescent panel indicator manufactured by NKK Switches, designed for 12V applications with a 60mA current rating and green diffused lens. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part features a round panel cutout of 0.48" (12.19mm) and solder lug termination.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-12-FF is determined by the following critical parameters:

• Voltage rating: 12V DC
• Lamp color and lens color: Green
• Lens transparency: Diffused
• Panel cutout shape: Round
• Lens style: Round with Flat Top
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The substitute part YB02KW01-5F12-JF maintains compatibility across voltage, color, lens transparency, and panel cutout shape. However, differences exist in technology type (LED vs. Incandescent), current rating, panel cutout dimensions, lens size, and termination style. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB02KW01-5F12-JF serves as an active substitute for the obsolete KB02KW01-12-FF. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs.

Key considerations for selection:

• The substitute operates at 20mA versus the original 60mA, resulting in reduced power consumption and heat generation.
• Panel cutout dimensions differ: the substitute requires a 0.63" (16.00mm) opening compared to the original 0.48" (12.19mm). Panel modification may be necessary.
• Lens size increases from 11.60mm to 16.00mm diameter, affecting visual prominence and panel aesthetics.
• Termination changes from solder lug to quick connect 0.110" (2.8mm), requiring circuit board redesign or adapter implementation.
• LED technology replaces incandescent technology, providing extended operational life and improved reliability.

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5F12-JF directly replace the KB02KW01-12-FF without modifications?

A: Direct replacement is not possible without modifications. The substitute requires a larger panel cutout (0.63" vs. 0.48"), different termination connections (quick connect vs. solder lug), and operates at reduced current (20mA vs. 60mA). Panel redesign and circuit board modifications are necessary.

Q: What are the primary differences between these two parts?

A: The main differences are technology type (LED vs. Incandescent), current rating (20mA vs. 60mA), panel cutout dimensions (0.63" vs. 0.48"), lens size (16.00mm vs. 11.60mm), and termination style (quick connect vs. solder lug).

Q: Are both parts compliant with current regulations?

A: Yes. Both the KB02KW01-12-FF and YB02KW01-5F12-JF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the substitute an LED instead of incandescent?

A: The original incandescent part is obsolete. NKK Switches provides the LED equivalent as the active product in this category, offering improved reliability, longer lifespan, and lower power consumption.

Q: What voltage and color specifications are maintained?

A: Both parts operate at 12V DC with green lamp and lens colors featuring diffused transparency, maintaining functional compatibility in applications requiring these specifications.
