Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB15NKW01-6G-JB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary operation)
• Mounting type: Panel Mount, Snap-In
• Actuator type: Rectangular Button
• Illumination: LED, Blue
• Operating temperature range: -25°C to 50°C
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: Must meet or exceed 1A
• Voltage ratings: Must meet or exceed 125V AC and 30V DC
• Illumination voltage: Nominal 3.3VDC to 3.6VDC acceptable
• Mechanical life: Must meet or exceed 100,000 cycles
• Electrical life: Must meet or exceed 50,000 cycles
• Panel cutout diameter: Mechanical fit requirements apply

The YB15NKW01-6G-JB qualifies as a direct substitute based on these parameters, with enhanced electrical and mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The YB15NKW01-6G-JB is the qualified substitute for the obsolete KB15NKW01-6G-JB. Both components are manufactured by NKK Switches and maintain identical compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 classification).

The substitute part offers superior electrical and mechanical performance: current rating increased from 1A to 3A, mechanical life extended from 100,000 to 1,000,000 cycles, and electrical life doubled from 50,000 to 100,000 cycles. The illumination voltage nominal specification differs slightly (3.3VDC versus 3.6VDC), remaining within acceptable operating parameters for LED illumination circuits.

The YB15NKW01-6G-JB maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete KB15NKW01-6G-JB.

Frequently Asked Questions (FAQ)

Q: Can the YB15NKW01-6G-JB directly replace the KB15NKW01-6G-JB in existing designs?

A: Yes. Both components share identical circuit configuration (SPDT), switch function (On-Mom), mounting type (Panel Mount, Snap-In), actuator type (Rectangular Button), illumination specification (LED, Blue), and operating temperature range (-25°C to 50°C). The substitute meets or exceeds all electrical and mechanical performance requirements of the original part.

Q: What is the difference in panel cutout diameter between these parts?

A: The KB15NKW01-6G-JB requires a 12.30mm circular cutout, while the YB15NKW01-6G-JB requires a 16.00mm circular cutout. Panel modifications may be necessary for mechanical installation of the substitute part.

Q: How do the illumination voltage specifications differ?

A: The KB15NKW01-6G-JB operates at 3.6VDC nominal illumination voltage, while the YB15NKW01-6G-JB operates at 3.3VDC nominal. Both specifications are compatible with standard LED illumination circuit designs operating in the 3.3V to 3.6V range.

Q: What are the termination differences between these parts?

A: The KB15NKW01-6G-JB uses Solder Lug termination, while the YB15NKW01-6G-JB offers Solder and Quick Connect 0.110" (2.8mm) termination options. Circuit board modifications may be required to accommodate the different termination style.

Q: Why is the KB15NKW01-6G-JB classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by NKK Switches. The YB15NKW01-6G-JB represents the active product line continuation with enhanced performance specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the KB15NKW01-6G-JB and YB15NKW01-6G-JB are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory requirements.
