Parameter Comparison

Engineering Selection Recommendations

The YB15KKW01-6F-JB is a qualified substitute for the obsolete KB15KKW01-6F-JB based on the following engineering criteria:

Functional Equivalence: Both components share identical circuit topology (SPDT), switch function (On-Momentary), voltage ratings (125V AC / 30V DC), illumination specifications (LED, Green, 3.3VDC), and mounting configuration (Panel Mount, Snap-In). Electrical and optical performance are directly compatible.

Performance Enhancement: The YB15KKW01-6F-JB provides superior reliability margins with 3A current rating (versus 1A), 1,000,000 mechanical cycle life (versus 100,000), and 100,000 electrical cycle life (versus 50,000). These enhancements reduce component stress and extend service life in equivalent applications.

Product Status Advantage: The YB15KKW01-6F-JB maintains active production status with documented inventory availability (1,109 units), ensuring supply chain continuity and long-term component sourcing compared to the obsolete KB15KKW01-6F-JB.

Mechanical Integration Consideration: The YB15KKW01-6F-JB requires a 16.00mm panel cutout diameter compared to the 12.30mm requirement of the KB15KKW01-6F-JB. Panel redesign or mechanical adapter implementation is necessary for direct retrofit applications.

Termination Compatibility: The YB15KKW01-6F-JB offers dual termination options (Solder and Quick Connect - 0.110" / 2.8mm) versus the solder lug termination of the KB15KKW01-6F-JB. Solder termination compatibility is maintained; quick connect termination provides additional flexibility for new designs.

Frequently Asked Questions (FAQ)

Q: Can the YB15KKW01-6F-JB directly replace the KB15KKW01-6F-JB in existing assemblies?

A: Electrical and functional compatibility is complete. Mechanical compatibility requires panel cutout modification from 12.30mm to 16.00mm diameter. Termination compatibility is maintained through solder lug connection method.

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

A: The primary differences are current rating (1A versus 3A), mechanical life (100,000 versus 1,000,000 cycles), electrical life (50,000 versus 100,000 cycles), panel cutout diameter (12.30mm versus 16.00mm), and product status (obsolete versus active). All electrical and optical specifications remain identical.

Q: Is the higher current rating of the YB15KKW01-6F-JB a concern for applications designed for 1A?

A: No. The 3A rating of the substitute component represents a performance margin that does not affect circuit operation in 1A applications. The component will operate within normal parameters with reduced stress.

Q: What termination options are available for the YB15KKW01-6F-JB?

A: The YB15KKW01-6F-JB supports both Solder and Quick Connect (0.110" / 2.8mm) termination styles. The solder lug method is compatible with existing KB15KKW01-6F-JB circuit board designs.

Q: Are there compliance or certification differences between these components?

A: Both components maintain MSL 1 (Unlimited) moisture sensitivity rating. RoHS3 compliance is confirmed for the KB15KKW01-6F-JB; compliance status for the YB15KKW01-6F-JB should be verified with the manufacturer for critical applications.

Q: What is the impact of the larger panel cutout diameter on retrofit applications?

A: The 16.00mm cutout diameter of the YB15KKW01-6F-JB requires mechanical panel modification or adapter implementation for direct retrofit into existing 12.30mm cutout openings. New designs can accommodate the larger diameter without additional considerations.
