Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB26SKW01-05-JC is determined by strict equivalence across the following critical parameters:

Circuit configuration must remain DPDT with On-On switching function. Current and voltage ratings must match or exceed the original specification: 3A (AC/DC), 125V AC, and 30V DC. Mounting type, panel cutout dimensions, and termination style must be identical to ensure mechanical and electrical compatibility within existing assemblies. Operating temperature range, mechanical life, and electrical life specifications must be maintained. RoHS and REACH compliance status must be preserved.

The substitute part LB26SKW01-5C05-JC meets all these criteria while offering the advantage of active product status and improved component availability.

Parameter Comparison

Engineering Selection Recommendations

The LB26SKW01-5C05-JC is the direct substitute for the obsolete LB26SKW01-05-JC. Both components are manufactured by NKK Switches within the LB series and maintain identical electrical and mechanical specifications across all critical parameters. The substitute part holds active product status, ensuring continued availability and supply chain reliability.

The primary difference between the two parts is the illumination technology: the original uses incandescent illumination powered by 5VAC, while the substitute employs LED illumination powered by 5VDC. This change does not affect the switch's core electrical performance or mechanical compatibility. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

Selection of the substitute part is appropriate for all applications where the original LB26SKW01-05-JC was specified, provided the system power supply can accommodate the change from 5VAC to 5VDC illumination voltage.

Frequently Asked Questions (FAQ)

Q: Can LB26SKW01-5C05-JC be used as a direct replacement for LB26SKW01-05-JC?

A: Yes. Both parts share identical DPDT circuit configuration, 3A current rating, 125V AC / 30V DC voltage ratings, panel mount snap-in design, and 16.20mm square panel cutout dimensions. Mechanical and electrical compatibility is maintained across all switching parameters.

Q: What is the difference between the two parts?

A: The illumination technology differs. LB26SKW01-05-JC uses incandescent red illumination at 5VAC, while LB26SKW01-5C05-JC uses LED red illumination at 5VDC. The switch circuitry and electrical ratings remain identical.

Q: Does the change from incandescent to LED illumination affect system design?

A: The illumination voltage changes from 5VAC to 5VDC. System power supplies must be capable of providing 5VDC to the illumination circuit. The switch's main circuit operation at 3A / 125V AC / 30V DC is unaffected.

Q: Are both parts RoHS compliant?

A: Yes. Both LB26SKW01-05-JC and LB26SKW01-5C05-JC are ROHS3 compliant and REACH unaffected.

Q: Why is the original part listed as obsolete?

A: LB26SKW01-05-JC is classified as obsolete by the manufacturer. LB26SKW01-5C05-JC is the active equivalent, offering the same functionality with improved component availability and supply chain continuity.

Q: Are the termination styles identical?

A: Yes. Both parts use solder and quick connect termination with 0.110" (2.8mm) connectors, ensuring compatibility with existing PCB layouts and connector systems.
