Key Parameters

Substitute Part Grouping Explanation

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

• Panel cutout shape and dimensions (round, 0.48" / 12.19mm)
• Lens color and transparency characteristics (yellow, diffused)
• Illumination type compatibility (incandescent technology)
• Manufacturer compatibility (NKK Switches product ecosystem)
• Environmental compliance certifications (RoHS3, REACH)
• Moisture sensitivity rating (MSL 1)

The substitute part YB02KW01-5D28-JD shares the same manufacturer and maintains compatibility with the mechanical panel interface requirements. However, this substitute represents a technology transition from incandescent to LED-based illumination with integrated resistor, reflecting the active product status and modern component availability.

Parameter Comparison

Engineering Selection Recommendations

Selection between the KB02KW01-28-EB and YB02KW01-5D28-JD is contingent upon application requirements and component availability constraints:

The KB02KW01-28-EB maintains obsolete status with 681 units currently in stock. This part satisfies applications requiring incandescent illumination technology and ROHS3 compliance verification.

The YB02KW01-5D28-JD is an active product with 809 units in stock, offering long-term availability and supply chain continuity. This substitute incorporates LED technology with integrated resistor, providing extended operational life and reduced power consumption compared to incandescent alternatives. Both parts maintain identical moisture sensitivity ratings and ECCN classifications, supporting equivalent environmental performance in sealed or controlled-humidity applications.

Frequently Asked Questions (FAQ)

Q: Can YB02KW01-5D28-JD directly replace KB02KW01-28-EB in existing assemblies?

A: Both parts share round panel cutout geometry compatible with 0.48" (12.19mm) openings. However, the technology transition from incandescent to LED with integrated resistor requires circuit-level evaluation. Voltage and current characteristics must be verified against application specifications before substitution.

Q: What is the primary difference between these two parts?

A: The KB02KW01-28-EB uses incandescent illumination technology, while the YB02KW01-5D28-JD employs LED technology with an integrated current-limiting resistor. This represents a functional upgrade path for obsolete component replacement.

Q: Are both parts compliant with environmental regulations?

A: The KB02KW01-28-EB is confirmed ROHS3 compliant and REACH unaffected. The YB02KW01-5D28-JD compliance status is not specified in available data and must be verified through the manufacturer for applications requiring regulatory certification.

Q: What is the inventory status for each part?

A: KB02KW01-28-EB has 681 units in stock as new original inventory. YB02KW01-5D28-JD has 809 units in stock as new original inventory. Both parts are currently available for procurement.

Q: Are there mechanical compatibility concerns with panel mounting?

A: Both parts feature round panel cutout requirements and are designed for NKK Switches panel-mount applications. Mechanical compatibility is maintained across the substitution, provided the panel opening dimensions conform to 0.48" (12.19mm) specifications.
