Engineering Selection Recommendations

The YB16RKW01-5F24-JB is functionally equivalent to the obsolete KB16RKW01-5F24-JB for applications requiring SPDT illuminated pushbutton switches with identical electrical specifications and operating parameters.

Selection Basis:

The substitute part maintains all critical functional parameters: SPDT circuit configuration, on-on switch function, 125 V AC / 30 V DC voltage ratings, 24 VDC LED green illumination, and identical operating temperature range. The YB series provides enhanced performance through increased current rating (3A versus 1A) and doubled mechanical and electrical life ratings, making it suitable for higher-duty applications without electrical or functional compromise.

Implementation Considerations:

Panel cutout diameter increases from 12.30mm to 16.00mm, requiring mechanical accommodation in the mounting panel. Termination style changes from solder lug to solder with quick connect 0.110" (2.8mm) option, necessitating circuit board layout and connector verification. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the YB16RKW01-5F24-JB directly replace the KB16RKW01-5F24-JB without modifications?

A: Electrical and functional replacement is direct. Mechanical panel cutout modification is required due to diameter increase from 12.30mm to 16.00mm. Termination style differs; verify circuit board connector compatibility with the quick connect 0.110" (2.8mm) termination option.

Q: What are the key differences between these two parts?

A: The YB16RKW01-5F24-JB provides higher current rating (3A versus 1A), doubled mechanical life (200,000 versus 100,000 cycles), and doubled electrical life (100,000 versus 50,000 cycles). Panel cutout diameter is larger (16.00mm versus 12.30mm), and termination includes quick connect option in addition to solder.

Q: Is the substitute part RoHS compliant?

A: RoHS compliance status for the YB16RKW01-5F24-JB is not specified in available data. Verify compliance documentation with the manufacturer for regulated applications.

Q: Will the higher current rating of the substitute affect circuit operation?

A: No. The substitute part is rated for higher current capacity (3A) than the original (1A). This provides additional safety margin and does not affect circuit operation at original current levels.

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

A: The original part uses solder lug termination; the substitute offers solder with quick connect 0.110" (2.8mm) option. Circuit board layout and connector compatibility must be verified before implementation.

Q: Is the operating temperature range identical?

A: Yes. Both parts operate across the identical temperature range of -25°C to 50°C.
