KB03KW01-28-EB Equivalent & Substitute Parts

Part Overview

The KB03KW01-28-EB is an incandescent panel indicator manufactured by NKK Switches, designed for 28V applications with a yellow lamp and white lens. This component features a round panel cutout (0.48" / 12.30mm) and solder lug termination. The product is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance, repair, and redesign applications where continued availability cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB03KW01-28-EB is determined by the following critical parameters:

• Voltage Rating: 28V operation is mandatory for direct electrical compatibility
• Termination Style: Solder lug connection is required for circuit board integration
• Panel Cutout Dimensions: Round 0.48" (12.30mm) cutout ensures mechanical fit
• Lamp and Lens Colors: Yellow lamp with white lens provides visual indication consistency
• Manufacturer Compatibility: NKK Switches product line maintains design consistency

The substitute part YB03KW01-5D28-JD is classified as a panel indicator from NKK Switches with active product status. However, this part represents a different product category (switch with integrated incandescent/LED indicator) rather than a direct functional equivalent. Substitution requires verification of mechanical fit, electrical interface compatibility, and operational characteristics specific to the application.

Parameter Comparison

Engineering Selection Recommendations

The KB03KW01-28-EB is obsolete and no longer in active production. The YB03KW01-5D28-JD maintains active product status from the same manufacturer, ensuring ongoing availability and support. Both components are ROHS3 compliant and carry identical moisture sensitivity ratings, meeting environmental and regulatory requirements.

Selection of the YB03KW01-5D28-JD as a substitute requires confirmation that the integrated switch functionality does not conflict with the application circuit design. The main part functions as a passive indicator only, while the substitute incorporates switching capability. Mechanical compatibility must be verified against panel cutout specifications and lens dimensions, as these parameters are not provided for the substitute part in the available data.

Frequently Asked Questions (FAQ)

Q: Can the YB03KW01-5D28-JD directly replace the KB03KW01-28-EB?

A: Direct replacement requires verification of three factors: (1) mechanical fit within the 0.48" round panel cutout, (2) electrical interface compatibility with the circuit design, accounting for the integrated switch function, and (3) confirmation that termination style matches the solder lug requirement.

Q: What is the primary reason for seeking a substitute?

A: The KB03KW01-28-EB is classified as obsolete. The YB03KW01-5D28-JD is an active product from the same manufacturer, providing continued availability for new designs and replacement applications.

Q: Are both parts RoHS compliant?

A: The KB03KW01-28-EB is ROHS3 compliant. RoHS compliance status for the YB03KW01-5D28-JD is not specified in the provided technical data.

Q: What parameters must match for substitution?

A: Critical matching parameters are voltage rating (28V), panel cutout shape and diameter (round, 0.48"), termination style (solder lug), and color specifications (yellow lamp, white lens). The substitute part must accommodate these requirements within its mechanical and electrical design.

Q: Does the substitute part have the same moisture sensitivity rating?

A: Yes. Both the KB03KW01-28-EB and YB03KW01-5D28-JD carry Moisture Sensitivity Level 1 (Unlimited), indicating equivalent environmental performance characteristics.
