KB16SKW01-05-FB Equivalent & Substitute Parts

Part Overview

The KB16SKW01-05-FB 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 component is designed for panel-mount front installation with incandescent green illumination. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications where continued functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB16SKW01-05-FB is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPDT
• Switch function must be On-On
• Voltage ratings must meet or exceed: 125V AC and 30V DC
• Current rating must support the application load

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Front
• Actuator type must be Square, Button
• Panel cutout dimensions must accommodate the physical installation

Operational Requirements:

• Operating temperature range must encompass -25°C to 50°C
• Illumination color must be Green to maintain visual consistency
• Termination style must be compatible with existing circuit board or wiring

The YB16SKW01-5F05-JF qualifies as a substitute based on matching SPDT circuit configuration, On-On function, equivalent voltage ratings, compatible panel-mount front installation, square button actuator, green illumination, and overlapping operating temperature range.

Engineering Selection Recommendations

The YB16SKW01-5F05-JF is an active product from NKK Switches and serves as the designated substitute for the obsolete KB16SKW01-05-FB. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Key Considerations for Selection:

The substitute part provides enhanced electrical life (100,000 cycles versus 50,000 cycles) and mechanical life (200,000 cycles versus 100,000 cycles), offering improved durability for extended-use applications. The current rating increase from 1A to 3A provides additional operational margin for applications with variable load conditions.

Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical modification to the mounting panel. Termination style changes from solder lug to solder with quick connect options, necessitating circuit board or wiring adaptation. Illumination transitions from incandescent to LED technology with voltage change from 5 VAC to 5 VDC, requiring illumination circuit modification.

The substitute part is currently in active production with confirmed inventory availability (1162 pieces), ensuring supply chain continuity for new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-5F05-JF directly replace the KB16SKW01-05-FB without modifications?

A: Direct replacement requires three modifications: panel cutout enlargement from 12.30mm to 16.00mm diameter, termination style adaptation from solder lug to solder/quick connect, and illumination circuit modification from 5 VAC incandescent to 5 VDC LED.

Q: What is the significance of the current rating increase from 1A to 3A?

A: The higher current rating of the substitute part provides operational margin for applications with load variations or future design modifications. The original 1A rating remains the limiting factor for the circuit unless the downstream load is redesigned.

Q: Are both parts electrically compatible in terms of voltage?

A: Yes. Both parts maintain identical voltage ratings of 125V AC and 30V DC, ensuring electrical compatibility at the circuit level.

Q: What are the implications of the illumination technology change?

A: The transition from incandescent to LED illumination reduces power consumption and extends illumination component life. However, the illumination circuit must be modified to supply 5 VDC instead of 5 VAC, and LED polarity must be observed during installation.

Q: Why is the panel cutout diameter different?

A: The YB series uses a larger 16.00mm cutout diameter compared to the KB series 12.30mm diameter. This is a mechanical design difference between product families and requires panel modification for installation.

Q: Are there any compliance or certification differences?

A: Both parts maintain ROHS3 compliance and REACH unaffected status. No compliance barriers exist for substitution from a regulatory perspective.

Q: What is the inventory status for the substitute part?

A: The YB16SKW01-5F05-JF is in active production with 1162 pieces currently in stock, ensuring availability for immediate procurement.
