Key Parameters

Substitute Part Grouping Explanation

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

• Panel cutout shape and dimensions (round, 0.48" / 12.19mm)
• Lens color and transparency (red, diffused)
• Mechanical form factor (round lens with flat top, 11.60mm diameter)
• Compliance certifications (RoHS3, REACH Unaffected, EAR99)
• Moisture sensitivity rating (MSL 1)

The substitute part YB02KW01-5C28-JC from NKK Switches shares the manufacturer lineage and maintains compatibility with the mechanical panel interface requirements of the KB02KW01-28-CB, while offering active product status and modern component technology.

Parameter Comparison

Engineering Selection Recommendations

The YB02KW01-5C28-JC is available as an active product with current manufacturing support, addressing the obsolescence status of the KB02KW01-28-CB. Both components maintain identical moisture sensitivity ratings and export classification codes. The substitute part incorporates integrated LED and resistor technology while maintaining NKK Switches manufacturing standards and compliance certifications. Selection should be based on specific application requirements regarding indicator technology (incandescent versus LED-based operation) and electrical interface compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the YB02KW01-5C28-JC directly replace the KB02KW01-28-CB in existing assemblies?

A: Mechanical panel interface compatibility is maintained through identical round cutout dimensions (0.48" / 12.19mm). Electrical interface verification is required, as the substitute incorporates integrated LED and resistor technology compared to the original incandescent design.

Q: What is the primary reason for seeking a substitute for the KB02KW01-28-CB?

A: The KB02KW01-28-CB is classified as obsolete. The YB02KW01-5C28-JC provides an active product alternative from the same manufacturer with current production availability.

Q: Are both parts compliant with the same regulatory standards?

A: Both components share EAR99 export classification and MSL 1 moisture sensitivity rating. RoHS3 compliance is confirmed for the KB02KW01-28-CB; compliance status for the substitute should be verified with the manufacturer for specific application requirements.

Q: What is the primary functional difference between these components?

A: The KB02KW01-28-CB uses incandescent lamp technology. The YB02KW01-5C28-JC integrates LED and resistor technology within the panel indicator assembly, offering different operational characteristics and power consumption profiles.
