KB16SKW01-6B-JB Equivalent & Substitute Parts

Part Overview

The KB16SKW01-6B-JB is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuitry with illuminated panel mount design. This component is rated for 1A at 125V AC and 30V DC, with white LED illumination at 3.3VDC nominal. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications where continued supply cannot be guaranteed.

Key Parameters

Substitute Part Grouping Explanation

The YB16SKW01-6B-JB qualifies as a functional substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• SPDT circuit configuration and On-On switch function
• 125V AC and 30V DC voltage ratings
• White LED illumination at 3.3VDC nominal
• Panel mount, front installation orientation
• Square button actuator with clear white filter/diffuser
• Operating temperature range of -25°C to 50°C
• ROHS3 compliance and REACH unaffected status

Differing Parameters:

• Current rating increased from 1A to 3A
• Panel cutout diameter increased from 12.30mm to 16.00mm
• Termination style changed from Solder Lug to Solder with Quick Connect 0.110" (2.8mm)
• Mechanical life upgraded from 100,000 to 200,000 cycles
• Electrical life upgraded from 50,000 to 100,000 cycles
• Product status changed from Obsolete to Active
• Includes tactile feedback feature

The higher current rating and enhanced mechanical/electrical life of the substitute part provide superior performance margins. Panel cutout diameter and termination style differences require mechanical and electrical interface verification during integration.

Parameter Comparison

Engineering Selection Recommendations

The YB16SKW01-6B-JB presents a viable substitute for the obsolete KB16SKW01-6B-JB based on regulatory compliance alignment. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications subject to these requirements.

The substitute part's active product status provides supply chain stability and long-term availability, addressing the primary limitation of the original obsolete component. The enhanced electrical and mechanical life ratings offer extended operational reliability.

Integration of the YB16SKW01-6B-JB requires validation of two mechanical factors: the increased panel cutout diameter (16.00mm versus 12.30mm) must be accommodated in the panel design, and the termination style transition from Solder Lug to Solder with Quick Connect 0.110" (2.8mm) must be compatible with the PCB or wiring harness interface. The higher current rating (3A versus 1A) is backward compatible with applications designed for 1A operation.

Frequently Asked Questions (FAQ)

Q: Can the YB16SKW01-6B-JB directly replace the KB16SKW01-6B-JB without any modifications?

A: Electrical compatibility is confirmed across voltage and circuit specifications. However, mechanical integration requires panel cutout enlargement from 12.30mm to 16.00mm diameter, and termination interface modification from Solder Lug to Quick Connect 0.110" (2.8mm) style. These changes necessitate panel redesign and wiring harness adaptation.

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

A: The substitute part supports higher current loads. Applications designed for 1A operation remain fully compatible, as the 3A-rated component operates safely at lower current levels. This provides additional design margin and supports potential future current requirement increases.

Q: Are both parts compliant with the same regulatory standards?

A: Yes. Both the KB16SKW01-6B-JB and YB16SKW01-6B-JB are ROHS3 compliant and REACH unaffected, ensuring equivalent regulatory status for applications subject to these requirements.

Q: Why is the panel cutout diameter different between these parts?

A: The YB16SKW01-6B-JB features a larger actuator assembly (16.00mm versus 12.30mm), which provides enhanced tactile feedback and improved mechanical durability. This dimensional change is a design characteristic of the newer series and requires corresponding panel modification.

Q: What is the impact of the termination style change?

A: The KB16SKW01-6B-JB uses Solder Lug termination for direct PCB soldering. The YB16SKW01-6B-JB employs Solder with Quick Connect 0.110" (2.8mm) termination, enabling both soldered connections and quick-disconnect harness interfaces. PCB or wiring design must accommodate this termination style difference.

Q: Is the substitute part suitable for long-term production use?

A: Yes. The YB16SKW01-6B-JB carries Active product status, indicating current manufacturing and ongoing supply availability. This contrasts with the obsolete KB16SKW01-6B-JB and supports sustained production requirements.
