Extended Operational Life: Both mechanical life (200,000 cycles) and electrical life (100,000 cycles) exceed the original specifications, providing improved reliability and extended service intervals.

Maintained Compliance: Both parts are RoHS3 compliant and share identical voltage ratings, temperature operating range, and circuit configuration, ensuring direct compatibility in existing designs.

Panel Mounting Compatibility: Both parts utilize identical panel mount, snap-in mounting methodology with compatible actuator geometry, supporting direct mechanical substitution in panel assemblies.

Frequently Asked Questions (FAQ)

Q: Can the YB16NKW01-5F-JF directly replace the KB16NKW01-5F-JF in existing applications?

A: Yes. Both parts share identical SPDT circuit configuration, on-on switch function, 125V AC / 30V DC voltage ratings, LED green illumination, and panel mount snap-in mounting type. The substitute part meets all core electrical and mechanical requirements for direct substitution.

Q: What is the difference in current rating between these parts?

A: The KB16NKW01-5F-JF is rated for 1A (AC/DC), while the YB16NKW01-5F-JF is rated for 3A (AC/DC). Applications designed for 1A operation remain fully compatible with the higher-rated substitute part.

Q: Are there panel cutout dimension differences?

A: The KB16NKW01-5F-JF requires a 12.30mm diameter circular cutout, while the YB16NKW01-5F-JF requires a 16.00mm diameter circular cutout. Panel modifications may be necessary for mechanical installation of the substitute part.

Q: What is the illumination voltage difference?

A: The KB16NKW01-5F-JF operates at 2.1 VDC illumination voltage, while the YB16NKW01-5F-JF operates at 2.0 VDC. This 0.1V difference is within acceptable tolerance for LED illumination circuits and does not affect functional compatibility.

Q: Does the YB16NKW01-5F-JF maintain RoHS3 compliance?

A: RoHS3 compliance status is not specified for the YB16NKW01-5F-JF in the provided data. Verification with the manufacturer is recommended if RoHS3 compliance is a design requirement.

Q: What are the termination style differences?

A: The KB16NKW01-5F-JF uses solder lug termination, while the YB16NKW01-5F-JF offers solder and quick connect 0.110" (2.8mm) termination options. Circuit board modifications may be required to accommodate the different termination style.
