KB01KW01-5C-JB LED Panel Indicator Equivalent & Substitute Parts

Part Overview

The KB01KW01-5C-JB is an LED panel indicator manufactured by NKK Switches, classified as a red LED with white clear lens designed for illuminated push-button applications. This component operates at 1.9V forward voltage with a maximum current rating of 30mA and features a square lens with flat top design. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and redesign applications where this component is specified in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB01KW01-5C-JB is determined by the following critical parameters:

• Electrical Compatibility: Forward voltage (1.9V) and maximum current rating (30mA) must remain within the original specification to ensure proper operation in existing circuit designs
• Optical Properties: Lamp color (red), lens color (white), and lens transparency (clear) must match to maintain visual consistency and light output characteristics
• Mechanical Compatibility: Panel cutout shape (round) and dimensions (0.48"/12.19mm) must accommodate the physical mounting interface
• Lens Geometry: Lens size (11.60mm) and style (square with flat top) determine visual appearance and light distribution
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be maintained for environmental and regulatory requirements

The YB01KW01-5C-JB qualifies as a substitute based on matching electrical voltage (1.9V), optical properties (red lamp, white clear lens), and regulatory compliance (ROHS3, REACH unaffected). However, differences in current rating, panel cutout dimensions, lens size, and termination style must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The YB01KW01-5C-JB is an active product from NKK Switches and represents a viable substitute for the obsolete KB01KW01-5C-JB based on electrical and optical parameter alignment. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and replacements.

Selection of the YB01KW01-5C-JB requires evaluation of the following design considerations:

• Panel Cutout Compatibility: The substitute requires a 0.63" (16.00mm) round cutout versus the original 0.48" (12.19mm). Existing panel designs must accommodate this larger opening, or mechanical adaptation may be necessary.
• Lens Size Difference: The substitute features a 15.00mm lens compared to the original 11.60mm, resulting in a larger visual indicator footprint.
• Current Rating: The substitute supports 40mA maximum current versus 30mA for the original part. Existing current-limiting circuits designed for 30mA operation remain compatible.
• Termination Interface: The substitute incorporates quick connect termination (0.110"/2.8mm), whereas the original termination style is not specified. Connector compatibility must be verified for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the YB01KW01-5C-JB directly replace the KB01KW01-5C-JB in existing designs?

A: Electrical and optical compatibility is confirmed. However, mechanical compatibility depends on panel cutout dimensions. The substitute requires a larger 0.63" (16.00mm) opening compared to the original 0.48" (12.19mm). Panel modifications or mechanical adapters may be required.

Q: Are the forward voltage and color specifications identical?

A: Yes. Both components operate at 1.9V forward voltage and feature red lamps with white clear lenses, ensuring consistent electrical behavior and visual appearance in the circuit.

Q: What is the difference in current rating between these parts?

A: The KB01KW01-5C-JB is rated for 30mA maximum current, while the YB01KW01-5C-JB supports 40mA. Existing designs operating at or below 30mA are fully compatible. The higher rating on the substitute provides additional design margin.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, satisfying environmental and regulatory requirements for industrial and commercial applications.

Q: What is the significance of the quick connect termination on the substitute?

A: The YB01KW01-5C-JB features quick connect termination (0.110"/2.8mm), which differs from the original part's unspecified termination. Connector compatibility must be verified with the specific application's wiring harness or socket interface.

Q: Is the larger lens size of the substitute a concern?

A: The substitute's 15.00mm lens is larger than the original 11.60mm lens. This results in a more prominent visual indicator but may affect panel aesthetics or space constraints. Verify that the larger lens does not interfere with adjacent components or design requirements.
