Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB01KW01-05-JC is determined by the following critical parameters that must remain constant across equivalent components:

• Series designation (LB)
• Voltage rating (5V)
• Lamp color and lens color (Red)
• Lens transparency (Clear)
• Panel cutout shape and dimensions (Round, 0.64"/16.26mm)
• Lens size and style (13.20mm, Square with Flat Top)
• Termination style (Quick Connect - 0.110"/2.8mm)
• Ratings classification (AC)

The LB01KW01-5C05-JC qualifies as a direct substitute based on identical mechanical and electrical interface parameters. The primary difference is the transition from incandescent to LED technology, which affects current consumption and product status but maintains full compatibility with the mechanical mounting and electrical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

The LB01KW01-5C05-JC is the designated substitute for the obsolete LB01KW01-05-JC. Both components maintain identical mechanical interfaces and electrical voltage specifications, ensuring direct compatibility in panel mounting applications.

The transition from incandescent to LED technology reduces current consumption from 115mA to 52mA, resulting in lower power dissipation and extended operational life. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system replacements.

The active product status of the LB01KW01-5C05-JC ensures ongoing availability and supply chain continuity, addressing the obsolescence constraint of the original component.

Frequently Asked Questions (FAQ)

Q: Can the LB01KW01-5C05-JC be used as a direct replacement for the LB01KW01-05-JC?

A: Yes. Both components share identical panel cutout dimensions, lens specifications, and quick connect termination. The mechanical mounting interface is fully compatible.

Q: What is the primary difference between these two components?

A: The main difference is the light source technology. The LB01KW01-05-JC uses incandescent illumination at 115mA, while the LB01KW01-5C05-JC uses LED technology at 52mA. Both operate at 5V with identical red lamp and lens coloring.

Q: Are there compliance or regulatory differences?

A: No. Both components are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status.

Q: Why is the original part listed as obsolete?

A: The LB01KW01-05-JC is no longer in active production. The LB01KW01-5C05-JC represents the current active equivalent within the LB series.

Q: Does the lower current rating of the substitute affect circuit design?

A: The reduced current consumption of the LED variant (52mA versus 115mA) may allow for simplified power supply design and reduced thermal management requirements. Existing circuits designed for the incandescent version will operate the LED substitute without modification, though power budget calculations should be updated to reflect the lower current draw.

Q: Are the lens appearance and brightness characteristics identical?

A: Both components feature identical lens size (13.20mm), lens style (square with flat top), and red coloring. Brightness characteristics differ due to the technology transition from incandescent to LED, but both are designed for the same visual indication application within the LB series.
