KB02KW01-01-JB Equivalent & Substitute Parts

Part Overview

The KB02KW01-01-JB is a neon panel indicator manufactured by NKK Switches, designed for 110V applications with a white diffused lens and 1.5mA operating current. This component features a round panel cutout (0.48" / 12.19mm) and solder lug termination. The product is classified as obsolete, making identification of suitable alternatives essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB02KW01-01-JB requires evaluation based on the following critical parameters:

Mechanical Compatibility:

• Panel cutout shape and dimensions must accommodate the physical form factor
• Lens size and style determine visual integration into the panel assembly
• Termination style affects circuit connection methodology

Electrical Compatibility:

• Operating voltage must match or be compatible with the circuit design
• Operating current must be within acceptable limits for the power supply and circuit protection
• Indicator type (neon vs. LED) represents a fundamental technology change with different electrical characteristics

Regulatory Compliance:

• RoHS and REACH compliance status must meet application requirements
• Product status (active vs. obsolete) affects long-term availability and supply chain considerations

The identified substitute YB02KW01-5F24-JB represents a technology transition from neon to LED technology with different electrical parameters and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Mechanical Replacement: The KB02KW01-01-JB cannot be directly replaced by YB02KW01-5F24-JB due to significant differences in panel cutout dimensions (0.48" vs. 0.63"), lens size (11.60mm vs. 16.00mm), and termination style (solder lug vs. quick connect). Panel modification would be required.

For Functional Equivalence: The YB02KW01-5F24-JB provides active product status with ROHS3 compliance and REACH unaffected certification, matching the regulatory profile of the main part. However, this substitute operates at 24V DC rather than 110V AC, requiring circuit redesign and power supply modification.

Compliance Considerations: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can YB02KW01-5F24-JB be installed in the same panel cutout as KB02KW01-01-JB? A: No. The substitute requires a 0.63" (16.00mm) cutout versus the original 0.48" (12.19mm) specification. Panel modification is necessary.

Q: What are the primary electrical differences between these parts? A: The main part operates at 110V with 1.5mA current using neon technology. The substitute operates at 24V DC with 10mA current using LED technology. Circuit redesign is required for voltage and current compatibility.

Q: Are the termination styles compatible? A: No. The main part uses solder lug termination while the substitute uses quick connect 0.110" (2.8mm) termination. Connection methodology must be adapted.

Q: Do both parts meet the same regulatory standards? A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements.

Q: Why is the main part classified as obsolete? A: Product status reflects manufacturer discontinuation. The active status of YB02KW01-5F24-JB indicates ongoing availability and support.

Q: What factors determine substitution feasibility? A: Mechanical compatibility (panel cutout and lens dimensions), electrical compatibility (voltage and current ratings), termination style compatibility, and regulatory compliance status are the primary determining factors.
