Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB01KW01-12-EB is determined by the following critical parameters:

• Voltage Rating: 12V AC operation
• Current Rating: 60mA maximum current draw
• Panel Cutout Compatibility: 0.48" (12.19mm) round opening
• Lens Characteristics: Yellow color with diffused transparency for visual indication
• Regulatory Compliance: RoHS3 and REACH status for environmental standards

The identified substitute part YB01KW01-5D12-JD represents an active product alternative from the same manufacturer. While this substitute maintains compatibility with the electrical specifications and panel mounting requirements, it operates as a panel indicator with integrated resistor design, representing a functional evolution from the original incandescent technology.

Engineering Selection Recommendations

The KB01KW01-12-EB is an obsolete product with active inventory availability. For new designs or system replacements, the YB01KW01-5D12-JD from NKK Switches is classified as an active product, ensuring long-term supply chain viability and manufacturer support.

Selection between these parts must account for the following compliance and operational factors:

• RoHS3 Compliance: The main part meets ROHS3 requirements; substitute part compliance status requires verification against specific application requirements.
• REACH Compliance: The main part is REACH Unaffected; substitute part status should be confirmed for regulated substance applications.
• Voltage Operation: The main part operates on 12V AC; the substitute operates on 12V DC, requiring circuit design compatibility assessment.
• Moisture Sensitivity: Both parts maintain MSL 1 (Unlimited) rating, suitable for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can the YB01KW01-5D12-JD directly replace the KB01KW01-12-EB in existing circuits?

A: Direct replacement requires verification of voltage supply compatibility. The KB01KW01-12-EB operates on 12V AC, while the YB01KW01-5D12-JD operates on 12V DC. Circuit redesign may be necessary if the existing power supply cannot accommodate this change.

Q: What are the key differences between these two panel indicators?

A: The KB01KW01-12-EB is an incandescent indicator rated for 12V AC at 60mA. The YB01KW01-5D12-JD is a panel indicator with integrated resistor design operating on 12V DC. Both are manufactured by NKK Switches and maintain identical moisture sensitivity ratings.

Q: Are both parts suitable for the same panel cutout dimensions?

A: Panel cutout compatibility information for the YB01KW01-5D12-JD is not provided in the available technical data. Physical dimensions and mounting specifications must be verified before installation.

Q: What is the inventory status of these parts?

A: The KB01KW01-12-EB has 907 pieces in stock as new original inventory. The YB01KW01-5D12-JD has 775 pieces in stock as new original inventory.

Q: Are both parts compliant with environmental regulations?

A: The KB01KW01-12-EB is ROHS3 Compliant and REACH Unaffected. The YB01KW01-5D12-JD compliance status for these regulations is not specified in the provided technical data and should be confirmed with the manufacturer for regulated applications.
