Procurement Notes

Verify availability status carefully as this specific part number may be classified as obsolete or end-of-life by the manufacturer. Confirm if replacement components are available through official Littelfuse substitution guides before finalizing procurement plans. Ensure compatibility with existing circuit designs when sourcing alternatives.

Selection Notes

Select this component for applications requiring precise high-voltage triggering thresholds between 220V and 250V. Consider the TO-92 package constraints for PCB layout and thermal management. Evaluate the 1A peak current rating against maximum expected surge conditions in the target circuit to ensure adequate safety margins during operation.

Part Context

This device belongs to the Kxxxzy Series SIDAC family from Littelfuse, specialized for high-voltage power control and circuit protection. These components function as bidirectional trigger devices, offering reliable performance in switching applications where rapid response to overvoltage events is critical for system safety and component longevity.

Replacement Considerations

Official substitutes include the K2400F1 model. Verify electrical parameter compatibility, specifically the breakover voltage and current ratings, before implementing any cross-reference solutions in existing designs.
