Matching Parameters (Substitution Basis):

• Circuit configuration: SPDT
• Switch function: On-Mom
• Current rating: 3A (AC/DC)
• Voltage rating - AC: 125V
• Voltage rating - DC: 30V
• Mounting type: Panel Mount, Snap-In
• Panel cutout dimensions: Square - 16.20mm x 16.20mm
• Actuator type: Square, Button
• Termination style: Solder, Quick Connect - 0.110" (2.8mm)
• Operating temperature range: -25°C ~ 50°C
• Mechanical life: 1,000,000 Cycles
• Electrical life: 100,000 Cycles
• RoHS compliance: ROHS3 Compliant

Differing Parameter:

• Illumination type and voltage: LB15SKW01-12-JB uses incandescent illumination at 12VAC, while LB15SKW01-6B-JB uses LED illumination at 3.3VDC

The substitute part maintains all critical electrical and mechanical specifications while offering an alternative illumination technology. The difference in illumination source and voltage reflects a design evolution within the LB series.

Parameter Comparison

Engineering Selection Recommendations

The LB15SKW01-6B-JB is the designated substitute for the obsolete LB15SKW01-12-JB. Both components maintain identical electrical ratings, mechanical specifications, and panel mounting characteristics. The substitute part is currently in active production status with higher inventory availability (1073 pcs vs. 893 pcs).

The primary design difference is the illumination technology: the substitute employs LED illumination at 3.3VDC instead of incandescent illumination at 12VAC. This change requires verification of the illumination circuit voltage supply in the target application. Both parts maintain ROHS3 compliance and identical lifecycle ratings.

For applications requiring the original incandescent illumination specification, the substitute part may require circuit modifications to accommodate the different illumination voltage and technology. For new designs or applications where LED illumination is acceptable, the LB15SKW01-6B-JB provides a direct functional replacement with improved component availability.

Frequently Asked Questions (FAQ)

Q: Can LB15SKW01-6B-JB directly replace LB15SKW01-12-JB without circuit modifications?

A: The substitute part maintains all electrical and mechanical switch specifications. However, the illumination circuit must be evaluated. The original part requires 12VAC illumination supply, while the substitute requires 3.3VDC. If the application circuit provides 12VAC illumination voltage, modifications are necessary to supply 3.3VDC to the LED illumination circuit.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a square panel cutout of 16.20mm x 16.20mm and use identical snap-in mounting mechanisms.

Q: What is the difference in illumination technology?

A: LB15SKW01-12-JB uses incandescent illumination (white) at 12VAC nominal voltage. LB15SKW01-6B-JB uses LED illumination (white) at 3.3VDC nominal voltage. LED technology typically offers longer operational life and lower power consumption compared to incandescent sources.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 3A at 125V AC and 30V DC, with identical SPDT circuit configuration and On-Mom switch function.

Q: What is the inventory status of each part?

A: LB15SKW01-12-JB (obsolete) has 893 pcs available. LB15SKW01-6B-JB (active) has 1073 pcs available.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
