KB03KW01-5C-JB LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The KB03KW01-5C-JB is a red LED panel indicator manufactured by NKK Switches, designed for applications requiring a 1.9V, 30mA diffused red lens indicator with solder lug termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production support and design updates. The part features a round panel cutout of 0.48" (12.19mm) and a rectangular lens measuring 16.10mm x 11.60mm with a flat top design.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the KB03KW01-5C-JB is determined by the following critical parameters:

• Electrical Compatibility: Forward voltage (1.9V) and maximum current rating (30mA or higher)
• Optical Properties: Red lamp color and red diffused lens
• Mechanical Fit: Panel cutout shape (round) and cutout diameter tolerance
• Lens Geometry: Physical dimensions and lens style (rectangle with flat top)
• Termination Interface: Connection method compatibility
• Regulatory Compliance: RoHS3 and REACH status

The identified substitute YB03KW01-5C-JB shares the same electrical voltage (1.9V), lamp color (red), lens color (red), lens transparency (diffused), and regulatory compliance profile. However, differences in current rating, panel cutout dimensions, lens size, and termination style must be evaluated for specific application requirements.

Engineering Selection Recommendations

The YB03KW01-5C-JB is an active product from NKK Switches and maintains full compliance with ROHS3 and REACH requirements, matching the regulatory profile of the obsolete KB03KW01-5C-JB.

Substitution feasibility depends on application-specific constraints:

• Electrical Compatibility: The YB03KW01-5C-JB supports a higher maximum current (40mA vs. 30mA) while maintaining the same 1.9V forward voltage, providing electrical compatibility for applications operating at or below 30mA.

• Mechanical Considerations: The YB03KW01-5C-JB requires a larger panel cutout (0.63" / 16.00mm vs. 0.48" / 12.19mm) and features a larger lens assembly (21.00mm x 15.00mm vs. 16.10mm x 11.60mm). Panel redesign or mechanical adaptation may be necessary.

• Termination Interface: The KB03KW01-5C-JB uses solder lug termination, while the YB03KW01-5C-JB uses quick connect terminals (0.110" / 2.8mm). Wiring harness or PCB modifications are required.

• Product Status: Selection of an active product (YB03KW01-5C-JB) over an obsolete part ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the YB03KW01-5C-JB directly replace the KB03KW01-5C-JB without modifications?

A: Direct replacement is not possible without mechanical and electrical modifications. The YB03KW01-5C-JB requires a larger panel cutout diameter, accommodates a larger lens assembly, and uses a different termination interface (quick connect vs. solder lug). Panel redesign and wiring harness changes are necessary.

Q: Are the electrical characteristics compatible?

A: Yes, the electrical characteristics are compatible. Both parts operate at 1.9V forward voltage. The YB03KW01-5C-JB supports a higher maximum current (40mA), making it suitable for applications operating at the KB03KW01-5C-JB's 30mA specification or lower.

Q: What are the key differences between these parts?

A: The primary differences are panel cutout diameter (0.48" vs. 0.63"), lens dimensions (16.10mm x 11.60mm vs. 21.00mm x 15.00mm), termination style (solder lug vs. quick connect), and product status (obsolete vs. active). Optical properties (red diffused lens) and electrical voltage remain identical.

Q: Does the YB03KW01-5C-JB meet the same regulatory requirements?

A: Yes, both parts are ROHS3 compliant and REACH unaffected, maintaining identical regulatory compliance profiles.

Q: What packaging options are available?

A: The KB03KW01-5C-JB is supplied in standard packaging, while the YB03KW01-5C-JB is available in bulk packaging.
