LB03KW01-01-JB Neon Panel Indicator - Equivalent & Substitute Parts

Part Overview

The LB03KW01-01-JB is an illuminated rectangular neon panel indicator manufactured by NKK Switches. This component is designed for AC applications requiring visual status indication in industrial control panels and equipment. The unit features a white neon lamp with a clear lens, rated for 110V AC operation at 1.5mA, and utilizes quick connect termination for standard panel mounting. The part maintains Active product status with full RoHS3 and REACH compliance, ensuring continued availability and regulatory alignment for new designs and legacy system maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the LB03KW01-01-JB is determined by strict equivalence across the following critical parameters:

Voltage and current ratings must match exactly (110V AC, 1.5mA) to ensure safe operation within the host equipment's electrical design.

Panel mounting geometry must be identical, including cutout shape (rectangle), cutout dimensions (0.88" x 0.64"), lens size (19.40mm x 13.20mm), and lens style (rectangle with flat top) to guarantee mechanical fit without panel modification.

Termination style must be consistent (Quick Connect - 0.110") to maintain compatibility with existing wiring harnesses and connection infrastructure.

Lamp type and optical characteristics (neon, white lamp color, white lens color, clear transparency) must remain constant to preserve the intended visual indication function and brightness characteristics.

Regulatory compliance status (RoHS3, REACH) must be maintained to satisfy current procurement and environmental standards.

The substitute part LB03GW01-01-JB meets all these criteria, differing only in the bezel color (gray versus black), which is a cosmetic variation that does not affect electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the LB03KW01-01-JB and LB03GW01-01-JB maintain Active product status with full RoHS3 compliance and REACH unaffected designation, confirming their suitability for current procurement cycles and regulatory requirements. Selection between these parts should be based on panel aesthetic requirements and bezel color specification. The black bezel variant (LB03KW01-01-JB) and gray bezel variant (LB03GW01-01-JB) are electrically and mechanically interchangeable. Inventory availability may also influence selection, as both parts are maintained in stock by the manufacturer. No additional testing or validation is required when substituting between these variants, provided the bezel color change is acceptable within the equipment design specification.

Frequently Asked Questions (FAQ)

Q: Can LB03GW01-01-JB be used as a direct replacement for LB03KW01-01-JB?

A: Yes. The parts are electrically and mechanically equivalent. The only difference is bezel color (gray versus black). All electrical ratings, panel cutout dimensions, lens specifications, termination style, and regulatory compliance are identical.

Q: What is the primary difference between these two part numbers?

A: The bezel color distinguishes these parts. LB03KW01-01-JB features a black bezel, while LB03GW01-01-JB features a gray bezel. This is a cosmetic variation with no impact on electrical performance or mechanical fit.

Q: Will the substitute part fit the same panel cutout?

A: Yes. Both parts have identical panel cutout dimensions (0.88" x 0.64") and lens size (19.40mm x 13.20mm). No panel modification is required when substituting between these variants.

Q: Are the termination connections compatible?

A: Yes. Both parts use identical Quick Connect - 0.110" (2.8mm) termination. Existing wiring harnesses and connection infrastructure require no modification.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both LB03KW01-01-JB and LB03GW01-01-JB are ROHS3 compliant and REACH unaffected, satisfying current environmental and procurement standards.

Q: What voltage and current ratings apply to both parts?

A: Both parts are rated for 110V AC operation at 1.5mA. Electrical specifications are identical.

Q: Can these parts be used interchangeably in existing equipment?

A: Yes, provided the bezel color change is acceptable within the equipment design specification. No electrical or mechanical modifications are required.
