• Operating temperature range (-25°C to 50°C)
• RoHS3 compliance and EAR99 ECCN classification

Differing Parameters:

• Current rating increased from 1A to 3A
• Panel cutout diameter increased from 12.30mm to 16.00mm
• Mechanical life extended from 100,000 to 200,000 cycles
• Electrical life extended from 50,000 to 100,000 cycles
• Termination style changed from solder lug to solder with quick connect 0.110" (2.8mm)
• Product status changed from obsolete to active

Parameter Comparison

Engineering Selection Recommendations

The YB16RKW01-5F-JB is a direct functional substitute for the obsolete KB16RKW01-5F-JB. Both components maintain identical voltage ratings, circuit topology, and illumination characteristics required for equivalent electrical performance.

The YB16RKW01-5F-JB offers enhanced reliability through increased current capacity (3A vs. 1A), extended mechanical and electrical life cycles, and active product status ensuring continued availability. These improvements represent a design upgrade rather than a compromise.

Integration considerations include panel cutout diameter modification (16.00mm vs. 12.30mm) and termination style transition from solder lug to quick connect 0.110" (2.8mm). Both components maintain ROHS3 compliance and identical operating temperature specifications, supporting direct substitution in compliant applications.

Frequently Asked Questions (FAQ)

Q: Can the YB16RKW01-5F-JB directly replace the KB16RKW01-5F-JB in existing designs?

A: Electrical substitution is direct. Panel cutout diameter and termination style require mechanical redesign. The larger 16.00mm cutout and quick connect termination necessitate panel modification and wiring harness adjustment.

Q: What is the impact of the increased current rating (3A vs. 1A)?

A: The YB16RKW01-5F-JB supports higher current loads without derating. Existing circuits operating at 1A or below remain fully compatible. No circuit redesign is required for applications within the original 1A specification.

Q: Are the illumination voltages compatible?

A: Yes. The 2VDC nominal illumination voltage of the YB16RKW01-5F-JB is compatible with circuits designed for the 2.1VDC specification of the KB16RKW01-5F-JB. LED illumination performance remains equivalent.

Q: What are the mechanical life implications?

A: The YB16RKW01-5F-JB provides 200,000 mechanical cycles versus 100,000 for the KB16RKW01-5F-JB. This represents extended service life and reduced maintenance frequency in high-cycle applications.

Q: Does the termination style change affect compatibility?

A: Termination style differs fundamentally. The KB16RKW01-5F-JB uses solder lug termination; the YB16RKW01-5F-JB uses solder with quick connect 0.110" (2.8mm). Wiring harness and PCB connection points require modification.

Q: Are both components RoHS compliant?

A: Yes. Both the KB16RKW01-5F-JB and YB16RKW01-5F-JB are ROHS3 compliant, supporting use in regulated applications requiring hazardous substance restrictions.
