Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB26SKW01-05-JB is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: DPDT topology must be maintained
• Switch Function: On-On operation required
• Current Rating: 3A (AC/DC) minimum
• Voltage Ratings: 125V AC and 30V DC minimum
• Mounting Interface: Panel Mount, Snap-In with 16.20mm x 16.20mm square cutout
• Actuator Geometry: Square button actuator
• Operating Temperature: -25°C to 50°C range
• Mechanical and Electrical Life: 200,000 and 100,000 cycles respectively
• Regulatory Compliance: ROHS3 Compliant

The substitute part LB26SKW01-6B-JB maintains equivalence across all critical electrical and mechanical parameters. The primary distinction is the illumination technology: the substitute employs LED white illumination at 3.3VDC nominal voltage, whereas the original uses incandescent white illumination at 5VAC nominal voltage. This difference does not affect the core switching functionality or electrical ratings.

Parameter Comparison

Engineering Selection Recommendations

The LB26SKW01-6B-JB is a direct functional substitute for the obsolete LB26SKW01-05-JB. Both components maintain identical electrical specifications, mechanical interfaces, and lifecycle ratings. The substitute part carries Active product status, ensuring continued availability and supply chain reliability.

Both parts satisfy ROHS3 compliance requirements and possess unlimited moisture sensitivity level (MSL 1), indicating no special handling or storage constraints during manufacturing and assembly processes.

The primary consideration for selection is illumination technology compatibility. The substitute employs LED illumination requiring 3.3VDC nominal voltage, whereas the original requires 5VAC nominal voltage for incandescent illumination. Circuit design must accommodate this voltage and current source difference. LED illumination typically offers extended operational life and reduced power consumption compared to incandescent technology.

Frequently Asked Questions (FAQ)

Q: Can LB26SKW01-6B-JB be used as a direct replacement for LB26SKW01-05-JB?

A: Yes. Both components share identical DPDT circuit configuration, 3A current rating, 125V AC and 30V DC voltage ratings, panel mount snap-in interface with 16.20mm square cutout, and identical mechanical/electrical lifecycle specifications. The illumination technology differs (LED versus incandescent), requiring verification that the circuit power supply can accommodate 3.3VDC LED voltage instead of 5VAC incandescent voltage.

Q: What is the impact of switching from incandescent to LED illumination?

A: The substitute part uses LED white illumination at 3.3VDC nominal voltage, while the original uses incandescent white illumination at 5VAC nominal voltage. This requires circuit modification to supply the appropriate voltage and current source. LED illumination typically consumes less power and provides longer operational life than incandescent technology.

Q: Are the panel cutout dimensions identical between both parts?

A: Yes. Both LB26SKW01-05-JB and LB26SKW01-6B-JB require a square panel cutout of 16.20mm x 16.20mm. Mechanical installation is identical for both components.

Q: What is the difference in product status between these parts?

A: LB26SKW01-05-JB is classified as Obsolete, while LB26SKW01-6B-JB is Active. The Active status of the substitute ensures ongoing manufacturing availability and supply chain continuity.

Q: Are both parts RoHS compliant?

A: Yes. Both LB26SKW01-05-JB and LB26SKW01-6B-JB are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity level, requiring no special environmental controls during storage or assembly.
