KB02KW01-5D-JD LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The KB02KW01-5D-JD is an LED panel indicator manufactured by NKK Switches, classified as an amber diffused lens indicator with 2V nominal voltage and 30mA maximum current rating. This component is designed for panel-mount applications with a round cutout and solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB02KW01-5D-JD is determined by the following critical parameters:

• Lamp Color & Lens Color: Must be amber to maintain visual indication consistency
• Voltage Rating: 2V nominal operation is required for circuit compatibility
• Current Rating: Maximum 30mA baseline; higher ratings (40mA) are acceptable if the circuit design permits
• Panel Cutout Shape & Dimensions: Round shape required; cutout diameter must accommodate mechanical fit
• Lens Transparency: Diffused or clear lenses are both acceptable for amber indicators, though diffused provides different light diffusion characteristics
• Termination Style: Solder lug is the primary termination; alternative termination styles require circuit board redesign
• Compliance: RoHS3 and REACH compliance must be maintained for regulatory continuity

The YB02KW01-5D-JD qualifies as a substitute based on matching lamp color, lens color, voltage rating, panel cutout shape, and compliance certifications. Differences in lens transparency, current rating, panel cutout dimensions, lens size, and termination style represent design trade-offs that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The KB02KW01-5D-JD is obsolete; the YB02KW01-5D-JD is the identified substitute from NKK Switches with active product status. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Selection of YB02KW01-5D-JD requires evaluation of the following design considerations:

• Panel Cutout Compatibility: The substitute requires a larger round cutout (0.63" vs. 0.48"), necessitating panel modification or acceptance of a larger lens footprint
• Lens Transparency: The clear lens of the substitute provides higher light transmission compared to the diffused lens of the original, affecting visual appearance and brightness perception
• Current Rating: The substitute's 40mA maximum rating exceeds the original 30mA specification; circuit design must confirm the power supply and current-limiting resistor accommodate this higher rating
• Termination Compatibility: The substitute uses quick connect termination (0.110" spade) instead of solder lug; circuit board redesign or connector adaptation is required

The active product status of YB02KW01-5D-JD provides supply chain continuity and ongoing manufacturer support compared to the obsolete KB02KW01-5D-JD.

Frequently Asked Questions (FAQ)

Q: Can YB02KW01-5D-JD be used as a direct replacement for KB02KW01-5D-JD without modifications?

A: No. The substitute differs in panel cutout dimensions (0.63" vs. 0.48"), lens transparency (clear vs. diffused), current rating (40mA vs. 30mA), and termination style (quick connect vs. solder lug). Panel cutout enlargement and termination adaptation are required.

Q: What is the primary advantage of substituting with YB02KW01-5D-JD?

A: The substitute has active product status, ensuring ongoing availability and manufacturer support. The KB02KW01-5D-JD is obsolete and subject to supply discontinuation.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both KB02KW01-5D-JD and YB02KW01-5D-JD are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: How does lens transparency affect indicator performance?

A: The diffused lens of the original part scatters light uniformly, while the clear lens of the substitute provides more concentrated light output. Visual brightness and viewing angle characteristics differ between the two designs.

Q: What circuit modifications are necessary for the substitute?

A: Verify that the power supply and current-limiting resistor accommodate the 40mA maximum rating. Confirm the circuit design accepts the quick connect termination or provide an adapter connector for solder lug compatibility.

Q: Is panel modification required for installation?

A: Yes. The substitute's larger lens diameter (15.00mm vs. 11.60mm) and panel cutout dimension (0.63" vs. 0.48") require panel cutout enlargement or acceptance of a larger visual footprint.
