Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB03KW01-6B-JB is determined by the following critical parameters:

Electrical Compatibility:

• Voltage rating: 3.6V
• Current rating: 30mA
• LED type and lamp color: White

Mechanical Compatibility:

• Panel cutout shape: Round
• Lens color: White
• Lens style: Rectangle with Flat Top

Regulatory & Environmental:

• RoHS3 Compliance
• Moisture Sensitivity Level 1
• REACH Unaffected status

The substitute part YB03KW01-6B-JB maintains identical electrical ratings (3.6V, 30mA) and lamp color (white). However, this substitute introduces differences in lens transparency (Diffused vs. Clear), panel cutout dimensions (0.63" vs. 0.48"), lens size (21.00mm x 15.00mm vs. 16.10mm x 11.60mm), and termination style (Quick Connect vs. standard). These differences require mechanical and optical evaluation for panel integration.

Parameter Comparison

Engineering Selection Recommendations

The KB03KW01-6B-JB is classified as Obsolete, making the identification of active alternatives essential for continued supply and design support.

YB03KW01-6B-JB Substitution Considerations:

The YB03KW01-6B-JB is an Active product from the same manufacturer (NKK Switches) with matching electrical specifications (3.6V, 30mA, white LED). Both components maintain ROHS3 Compliance, Moisture Sensitivity Level 1, and REACH Unaffected status, ensuring regulatory alignment.

Mechanical differences exist: the YB03KW01-6B-JB requires a larger panel cutout (0.63" vs. 0.48") and features a larger lens assembly (21.00mm x 15.00mm vs. 16.10mm x 11.60mm). The lens transparency differs (Diffused vs. Clear), which affects light distribution characteristics. The YB03KW01-6B-JB includes Quick Connect termination (0.110" / 2.8mm), whereas the main part does not specify termination style.

Substitution of the KB03KW01-6B-JB with the YB03KW01-6B-JB requires mechanical redesign of the panel cutout and lens cavity, as well as evaluation of the optical diffusion effect on system visibility requirements.

Frequently Asked Questions (FAQ)

Q: Can the YB03KW01-6B-JB be used as a direct drop-in replacement for the KB03KW01-6B-JB?

A: No. While both components share identical electrical ratings (3.6V, 30mA) and lamp color (white), mechanical differences prevent direct substitution. The YB03KW01-6B-JB requires a larger panel cutout diameter (0.63" vs. 0.48") and accommodates a larger lens assembly. Panel modification is necessary.

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

A: The KB03KW01-6B-JB features a Clear lens transparency, providing direct light transmission. The YB03KW01-6B-JB features a Diffused lens transparency, which scatters light for a broader viewing angle and softer appearance. This affects optical performance and should be evaluated against application requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the KB03KW01-6B-JB and YB03KW01-6B-JB are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Regulatory compliance is maintained across both components.

Q: What is the significance of the product status difference?

A: The KB03KW01-6B-JB is Obsolete, indicating discontinued production and limited availability. The YB03KW01-6B-JB is Active, ensuring ongoing manufacturing, supply chain availability, and long-term support. For new designs or production continuity, the Active status of the YB03KW01-6B-JB provides supply security.

Q: Does the Quick Connect termination of the YB03KW01-6B-JB affect electrical performance?

A: No. The Quick Connect termination (0.110" / 2.8mm) is a mechanical interface feature and does not alter electrical performance. Both components operate at identical voltage and current ratings. Termination style selection depends on circuit board design and connector compatibility requirements.
