Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB15CKW01/C-01-JC is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Current rating: 3A (AC/DC)
• Voltage rating: 125V AC / 30V DC minimum
• Mounting type: Panel Mount, Snap-In
• Panel cutout diameter: 22.00mm
• Termination style: Solder, Quick Connect - 0.110" (2.8mm)
• Mechanical life: 1,000,000 Cycles
• Electrical life: 100,000 Cycles

Allowable Variations:

• Illumination type and color (illuminated vs. non-illuminated)
• Actuator type and marking
• Operating temperature range (provided minimum specifications are met)
• Product status (active vs. discontinued)

The LB15CKW01/CUL qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while differing only in illumination configuration and actuator design.

Parameter Comparison

Engineering Selection Recommendations

The LB15CKW01/CUL is the manufacturer-recommended substitute for the discontinued LB15CKW01/C-01-JC. Both components share identical electrical ratings, circuit configuration, and mechanical specifications. The primary functional difference is the absence of integrated neon red illumination in the substitute part; the LB15CKW01/CUL features a standard non-illuminated design with a plunger-type actuator.

The substitute part offers an extended operating temperature range (-25°C to 70°C versus -25°C to 50°C), providing improved thermal performance. The LB15CKW01/CUL maintains active product status, ensuring continued availability and supply chain reliability compared to the discontinued original part.

Both components are manufactured by NKK Switches within the LB series and utilize identical panel cutout dimensions and termination configurations, enabling direct mechanical and electrical integration into existing designs without PCB or panel modifications.

Frequently Asked Questions (FAQ)

Q: Can the LB15CKW01/CUL replace the LB15CKW01/C-01-JC in all applications?

A: The LB15CKW01/CUL is electrically and mechanically compatible with the LB15CKW01/C-01-JC. The primary difference is the absence of integrated neon red illumination. If illumination is required, external illumination solutions must be implemented or an alternative illuminated switch model selected.

Q: What are the key differences between these two parts?

A: The main differences are: (1) illumination type and color—the original includes neon red illumination at 110VAC nominal, while the substitute is non-illuminated; (2) actuator design—the original has a round button with clear red filter/diffuser, the substitute uses a plunger-type actuator; (3) operating temperature range—the substitute supports -25°C to 70°C versus -25°C to 50°C for the original.

Q: Are the panel cutout dimensions identical?

A: Yes. Both parts require a circular 22.00mm diameter panel cutout and use identical snap-in mounting mechanisms. No panel modifications are necessary for substitution.

Q: Do both parts use the same termination style?

A: Yes. Both the LB15CKW01/C-01-JC and LB15CKW01/CUL use solder and quick connect termination with 0.110" (2.8mm) spacing, ensuring compatibility with existing PCB layouts and connector systems.

Q: What is the electrical performance difference?

A: There is no electrical performance difference. Both parts are rated for 3A at 125V AC and 30V DC, with identical mechanical life (1,000,000 cycles) and electrical life (100,000 cycles) specifications.

Q: Why is the original part discontinued?

A: The LB15CKW01/C-01-JC is discontinued at DiGi Electronics. The LB15CKW01/CUL is the active manufacturer-recommended alternative within the NKK Switches LB series.
