Substitute Part Grouping Explanation

The LB15CKW01-5C12-JC qualifies as a direct substitute for the LB15CKW01-12-JC based on the following critical parameters:

Matching Parameters:

• Manufacturer: NKK Switches (same manufacturer ensures design compatibility)
• Series: LB (same product family)
• Circuit Configuration: SPDT (identical electrical switching topology)
• Switch Function: On-Mom (identical operational behavior)
• Current Rating: 3A (AC/DC) (identical load capacity)
• Voltage Rating - AC: 125 V (identical AC specification)
• Voltage Rating - DC: 30 V (identical DC specification)
• Mounting Type: Panel Mount, Snap-In (identical mechanical interface)
• Panel Cutout Dimensions: Circular - 22.00mm Dia (identical installation footprint)
• Actuator Type: Round, Button (identical user interface)
• Color - Actuator/Cap: Clear (Red Filter/Diffuser) (identical visual appearance)
• Termination Style: Solder, Quick Connect - 0.110" (2.8mm) (identical electrical connection)
• Operating Temperature: -25°C ~ 50°C (identical thermal range)
• Mechanical Life: 1,000,000 Cycles (identical mechanical durability)
• Electrical Life: 100,000 Cycles (identical electrical durability)
• RoHS Status: ROHS3 Compliant (identical compliance)

Distinguishing Parameter:

• Illumination Type: Incandescent, Red (main part) vs. LED, Red (substitute)
• Illumination Voltage: 12 VAC (main part) vs. 12 VDC (substitute)

The substitution is valid because the illumination type and voltage differ only in technology (incandescent to LED) and supply polarity (AC to DC), while all functional switching parameters remain identical.

Engineering Selection Recommendations

The LB15CKW01-5C12-JC is the appropriate substitute for the obsolete LB15CKW01-12-JC. The substitute maintains active product status with NKK Switches, ensuring continued availability and manufacturer support. Both components carry identical ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

The primary consideration for selection is the illumination technology transition from incandescent to LED and the corresponding voltage supply change from 12 VAC to 12 VDC. This change requires verification that the system's illumination power supply can accommodate DC voltage delivery. All switching parameters—circuit topology, current capacity, voltage ratings, mechanical interface, and operational life specifications—remain unchanged, ensuring functional equivalence in the switching circuit.

Frequently Asked Questions (FAQ)

Q: Can LB15CKW01-5C12-JC directly replace LB15CKW01-12-JC in existing installations?

A: Direct mechanical and electrical replacement is possible for the switching function. However, the illumination circuit requires modification: the substitute requires 12 VDC supply instead of 12 VAC. Verify that your system can provide DC voltage to the illumination circuit before implementation.

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

A: The illumination technology differs. The original uses incandescent illumination powered by 12 VAC; the substitute uses LED illumination powered by 12 VDC. All switching characteristics (SPDT, 3A/125V, On-Mom function) are identical.

Q: Are the mechanical interfaces identical?

A: Yes. Both components feature identical panel-mount snap-in installation with a 22.00mm circular cutout, round button actuator, and 0.110" (2.8mm) quick-connect termination.

Q: Why is the original part obsolete?

A: The LB15CKW01-12-JC is classified as obsolete by NKK Switches. The LB15CKW01-5C12-JC represents the active product line continuation with LED illumination technology.

Q: Do both parts meet current compliance standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the inventory status of the substitute?

A: The LB15CKW01-5C12-JC is actively stocked with 1079 pieces available as new original inventory, compared to 655 pieces of the obsolete original part.
