KB16RKW01-6F-JB Equivalent & Substitute Parts

Part Overview

The KB16RKW01-6F-JB is an illuminated pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 125V AC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The switch combines panel-mount installation with LED illumination (green, 3.3VDC) and solder lug termination, serving applications requiring low-current switching with visual feedback.

Substitute Part Grouping Explanation

The YB16RKW01-6F-JB qualifies as a functional substitute based on the following alignment of critical parameters:

Matching Parameters:

SPDT circuit configuration and On-On switch function
125V AC voltage rating (primary operating specification)
30V DC voltage rating
Panel mount, front installation geometry
LED green illumination at 3.3VDC
Rectangular button actuator
Operating temperature range (-25°C to 50°C)
ROHS3 compliance and REACH unaffected status

Differing Parameters:

Current rating increased from 1A to 3A
Panel cutout diameter: 12.30mm (KB16) vs. 16.00mm (YB16)
Termination style: Solder lug (KB16) vs. Solder/Quick Connect 0.110" (YB16)
Mechanical life: 100,000 cycles (KB16) vs. 200,000 cycles (YB16)
Electrical life: 50,000 cycles (KB16) vs. 100,000 cycles (YB16)
Product status: Obsolete (KB16) vs. Active (YB16)

The higher current rating of the YB16RKW01-6F-JB provides design margin for applications originally specified at 1A, while maintaining voltage and circuit compatibility.

Engineering Selection Recommendations

The YB16RKW01-6F-JB is an active product with current manufacturing support from NKK Switches, addressing the obsolescence status of the KB16RKW01-6F-JB. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

Selection of the YB16RKW01-6F-JB introduces the following design considerations:

Mechanical Integration: The panel cutout diameter increases from 12.30mm to 16.00mm, requiring panel modification or redesign of mounting hardware.

Electrical Termination: Transition from solder lug to solder/quick connect 0.110" termination necessitates wiring harness reconfiguration.

Current Capacity: The 3A rating (versus 1A original specification) provides operational margin and extended component life through reduced thermal stress.

Lifecycle Performance: Doubled mechanical and electrical life ratings (200,000 and 100,000 cycles respectively) extend maintenance intervals and system reliability.

Frequently Asked Questions (FAQ)

Q: Can the YB16RKW01-6F-JB directly replace the KB16RKW01-6F-JB without modifications?

A: Electrical substitution is valid for applications operating at or below 1A. Physical installation requires panel cutout enlargement from 12.30mm to 16.00mm diameter. Termination wiring must be adapted from solder lug to quick connect 0.110" configuration.

Q: What is the significance of the increased 3A current rating on the YB16RKW01-6F-JB?

A: The higher current rating indicates increased contact capacity and thermal performance. Applications originally specified at 1A operate within the YB16 design margin, reducing contact wear and extending electrical life from 50,000 to 100,000 cycles.

Q: Are both components suitable for the same voltage applications?

A: Yes. Both components share identical voltage ratings: 125V AC and 30V DC. Voltage compatibility is maintained across the substitution.

Q: What termination differences exist between these components?

A: The KB16RKW01-6F-JB uses solder lug termination for direct wire attachment. The YB16RKW01-6F-JB provides dual termination options: solder and quick connect 0.110" (2.8mm) spade terminals, offering installation flexibility.

Q: Does the panel cutout size difference affect circuit functionality?

A: Panel cutout diameter is a mechanical specification only. The larger 16.00mm cutout on the YB16RKW01-6F-JB does not affect electrical circuit operation but requires physical panel modification for installation.

Q: Are regulatory certifications equivalent between the two components?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for equivalent applications.
