Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-28-JC is determined by the following critical parameters:

• Manufacturer: NKK Switches
• Indicator Type: Incandescent panel indicator
• Lamp and Lens Color: Red
• Lens Transparency: Diffused
• Voltage Rating: 28V
• Panel Cutout Dimensions: 0.48" (12.19mm) round
• Termination Style: Solder lug
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part YB02KW01-5C24-JC is manufactured by the same supplier (NKK Switches) and shares the same mechanical interface requirements. However, this part represents a different product category (panel indicator with integrated LED and resistor) and operates under different electrical specifications, requiring careful evaluation of application requirements before substitution.

Parameter Comparison

Engineering Selection Recommendations

The KB02KW01-28-JC is obsolete and no longer in active production. The YB02KW01-5C24-JC is an active product from the same manufacturer and maintains compliance with ECCN EAR99 and Moisture Sensitivity Level 1 classifications.

Selection between these parts must be based on:

• Electrical compatibility: The main part operates at 28V with incandescent technology. The substitute part uses LED technology with integrated resistor, requiring verification of voltage and current specifications for the target application.
• Mechanical fit: Both parts are manufactured by NKK Switches and may share compatible panel cutout dimensions, but this must be confirmed against the specific application requirements.
• Compliance requirements: Both parts meet ECCN EAR99 classification. RoHS3 compliance status of the substitute part must be verified for applications requiring this certification.

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5C24-JC directly replace the KB02KW01-28-JC in existing applications?

A: Direct replacement requires verification of electrical specifications. The main part is incandescent technology operating at 28V, while the substitute is LED-based with integrated resistor. Voltage rating, current draw, and light output characteristics must be confirmed for compatibility with the target circuit and application requirements.

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

A: The KB02KW01-28-JC is an incandescent indicator with red diffused lens and solder lug termination. The YB02KW01-5C24-JC is a panel indicator with integrated LED and resistor. These represent different technology platforms with different electrical operating characteristics.

Q: Why is the KB02KW01-28-JC listed as obsolete?

A: The KB02KW01-28-JC is classified as obsolete by the manufacturer, indicating it is no longer in active production. Existing inventory may be available through authorized distributors, but long-term availability cannot be guaranteed.

Q: Are both parts RoHS3 compliant?

A: The KB02KW01-28-JC is confirmed ROHS3 Compliant. RoHS3 compliance status for the YB02KW01-5C24-JC must be verified through the manufacturer or authorized distributor.

Q: What is the panel cutout requirement for the KB02KW01-28-JC?

A: The panel cutout is round with dimensions of 0.48" (12.19mm). Mechanical compatibility of substitute parts must be confirmed against this specification.
