KB02KW01-05-FF Equivalent & Substitute Parts

Part Overview

The KB02KW01-05-FF is an incandescent panel indicator manufactured by NKK Switches, designed for illuminated pushbutton applications with a green diffused lens. This component operates at 5V with 115mA current consumption and features a round panel cutout of 0.48" (12.19mm) diameter. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB02KW01-05-FF is determined by the following critical parameters:

• Voltage Rating: 5V operation is mandatory for direct electrical compatibility
• Panel Cutout Dimensions: Round 0.48" (12.19mm) cutout ensures mechanical fit in existing panel installations
• Lens Color and Transparency: Green diffused lens maintains visual consistency and functional indication
• Current Rating: 115mA establishes the electrical load requirement
• Compliance Standards: RoHS3 and REACH compliance ensure regulatory alignment

The identified substitute part YB02KW01-5F05-JF represents an alternative from the same manufacturer (NKK Switches) with active product status. However, this substitute employs a different technology platform (LED with resistor versus incandescent), which introduces functional differences that must be evaluated against the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The KB02KW01-05-FF is classified as obsolete, necessitating evaluation of alternatives for new designs or system replacements. The YB02KW01-5F05-JF is currently active in production and manufactured by the same supplier, providing supply chain continuity.

Selection between these components must account for:

• Product Status: The main part is obsolete; the substitute is active and available
• Regulatory Compliance: Both components meet RoHS3 requirements based on available data
• Technology Transition: The substitute employs LED technology with integrated resistor, representing a shift from incandescent illumination

Direct substitution requires confirmation that the substitute part meets the specific voltage, current, and mechanical requirements of the target application, as complete electrical specifications for the YB02KW01-5F05-JF are not provided in this reference.

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5F05-JF directly replace the KB02KW01-05-FF in existing installations?

A: Direct mechanical replacement is possible if panel cutout dimensions are compatible. Electrical compatibility requires confirmation of voltage rating, current consumption, and LED color specifications for the substitute part, which are not fully documented in this reference.

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

A: The main part uses incandescent illumination technology, while the substitute uses LED technology with integrated resistor. This represents a fundamental change in light source, affecting power consumption, thermal characteristics, and light output properties.

Q: Are both parts RoHS3 compliant?

A: The KB02KW01-05-FF is confirmed RoHS3 compliant. RoHS3 compliance status for the YB02KW01-5F05-JF is not specified in the provided data and should be verified with the manufacturer.

Q: What is the panel cutout requirement for these components?

A: The KB02KW01-05-FF requires a round panel cutout of 0.48" (12.19mm) diameter. Panel cutout specifications for the YB02KW01-5F05-JF are not provided and must be confirmed before installation.

Q: Why is the KB02KW01-05-FF obsolete?

A: Product obsolescence is determined by the manufacturer. Obsolete status indicates the part is no longer in active production, making the active substitute part YB02KW01-5F05-JF a viable option for ongoing supply requirements.
