KB16NKW01-6F-JB Equivalent & Substitute Parts

Part Overview

The KB16NKW01-6F-JB is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with a 1A current rating at 125V AC. This panel-mount, snap-in component is designed for standard switching applications with integrated LED illumination in green. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KB16NKW01-6F-JB is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Voltage rating: 125V AC minimum
• Mounting type: Panel Mount, Snap-In
• Illumination: LED, Green at 3.3 VDC
• Operating temperature range: -25°C to 50°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: May exceed 1A (higher current ratings are backward compatible for lower-current applications)
• Mechanical and electrical life: May exceed specified values
• Panel cutout dimensions: May differ if mechanical integration permits
• Termination style: May differ if electrical connection is maintained
• Product status: Active status preferred for ongoing availability

The YB16NKW01-6F-JB meets all mandatory compatibility parameters while providing enhanced specifications in current rating (3A), mechanical life (200,000 cycles), and electrical life (100,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

The YB16NKW01-6F-JB is a direct functional substitute for the obsolete KB16NKW01-6F-JB. Selection of this substitute is supported by the following engineering factors:

Product Status Advantage: The YB16NKW01-6F-JB maintains active product status with NKK Switches, ensuring continued availability and supply chain reliability compared to the obsolete KB16NKW01-6F-JB.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component deployment.

Enhanced Performance Specifications: The substitute provides superior mechanical life (200,000 cycles versus 100,000 cycles) and electrical life (100,000 cycles versus 50,000 cycles), delivering extended operational durability in equivalent applications.

Current Rating Compatibility: The increased current rating of 3A in the substitute accommodates the original 1A requirement with design margin, supporting applications with potential future current demand increases.

Mechanical Integration Consideration: Panel cutout dimensions differ (16.00mm diameter for YB16NKW01-6F-JB versus 12.30mm diameter for KB16NKW01-6F-JB). Mechanical integration assessment is required to confirm panel compatibility.

Frequently Asked Questions (FAQ)

Q: Can the YB16NKW01-6F-JB directly replace the KB16NKW01-6F-JB in existing designs?

A: Electrical and functional compatibility is confirmed. The substitute maintains identical SPDT circuit configuration, On-On switch function, 125V AC voltage rating, and 3.3 VDC green LED illumination. Mechanical integration must be verified due to panel cutout dimension differences (16.00mm versus 12.30mm diameter).

Q: What is the significance of the higher current rating in the substitute part?

A: The YB16NKW01-6F-JB 3A rating exceeds the original 1A requirement, providing design margin and supporting applications with higher current demands. This represents an enhancement rather than a limitation for the original 1A application.

Q: Are there termination differences between these parts?

A: Yes. The KB16NKW01-6F-JB uses solder lug termination, while the YB16NKW01-6F-JB provides solder and quick connect 0.110" (2.8mm) termination options. Electrical connection compatibility must be confirmed for your specific application.

Q: Why is product status relevant to component selection?

A: The KB16NKW01-6F-JB obsolete status indicates discontinued manufacturing and limited inventory availability. The YB16NKW01-6F-JB active status ensures ongoing production, supply chain availability, and long-term design support.

Q: Do both parts meet current environmental regulations?

A: Yes. Both the KB16NKW01-6F-JB and YB16NKW01-6F-JB maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component use.

Q: What mechanical life improvement does the substitute provide?

A: The YB16NKW01-6F-JB delivers 200,000 mechanical cycles compared to 100,000 cycles in the original part, representing a 100% increase in mechanical durability and extended operational lifespan.
