Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB03KW01-05-JC is determined by the following critical parameters:

Mechanical Compatibility:

• Panel cutout shape and dimensions (0.88" x 0.64" / 22.35mm x 16.26mm rectangle)
• Lens size (19.40mm x 13.20mm)
• Lens style (rectangle with flat top)
• Termination style (quick connect - 0.110" / 2.8mm)

Electrical Compatibility:

• Voltage rating (5V)
• Lamp color (red)
• Lens color (red)

Regulatory Compliance:

• RoHS3 compliance
• REACH unaffected status

The substitute part LB03KW01-5C05-JC shares the same series designation (LB), base product number (LB03), mechanical form factor, voltage rating, color specifications, and regulatory compliance. The primary difference is the technology transition from incandescent to LED, which affects current consumption and lens transparency characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LB03KW01-5C05-JC is the designated substitute for the obsolete LB03KW01-05-JC. Both components maintain identical mechanical interfaces, voltage specifications, and regulatory compliance certifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The transition from incandescent to LED technology results in reduced current consumption (52mA versus 115mA), which may require circuit-level evaluation in applications with current-limiting resistors or power supply constraints. The change in lens transparency from diffused to clear affects light diffusion characteristics and should be assessed for visual indication requirements in the target application.

Both parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can LB03KW01-5C05-JC be used as a direct replacement for LB03KW01-05-JC?

A: Yes. Both components share identical panel cutout dimensions (0.88" x 0.64"), lens size (19.40mm x 13.20mm), lens style (rectangle with flat top), termination style (quick connect - 0.110"), voltage rating (5V), and color specifications (red lamp and lens). Mechanical and electrical interfaces are compatible.

Q: What are the differences between these two parts?

A: The primary differences are technology type (incandescent versus LED), current consumption (115mA versus 52mA), and lens transparency (diffused versus clear). The substitute part is in active production, while the original is obsolete.

Q: Does the change from diffused to clear lens affect compatibility?

A: The lens transparency change alters light diffusion characteristics. Applications requiring specific light distribution patterns should evaluate whether the clear lens of the substitute part meets visual indication requirements.

Q: Are there any power supply considerations when switching to the substitute?

A: The substitute part consumes 52mA compared to the original 115mA. Existing power supply designs will operate within reduced current parameters. Applications with current-limiting resistors should be reviewed to ensure proper LED operation at 5V.

Q: Are both parts compliant with current regulations?

A: Yes. Both the LB03KW01-05-JC and LB03KW01-5C05-JC are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial applications.
