Procurement Notes

Verify the specific suffix F4-A against official datasheets to confirm package type and performance characteristics. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Selection Notes

Select this component when a single channel of isolation with NPN output is required. Consider the 2500 Vrms isolation rating for safety applications. Verify that the 50 mA collector current and 180 mW power dissipation meet circuit load requirements. Check operating temperature limits for environmental suitability.

Part Context

This part belongs to the PS2801 series of optically coupled isolators. The series typically includes variants like PS2801-1 and PS2801-4. These devices are designed for compact applications requiring reliable electrical isolation between input and output circuits using optical transmission technology.

Replacement Considerations

Cross-reference with other PS2801 series variants from Renesas or CEL. Verify pinout compatibility and electrical parameter equivalence. Confirm package dimensions match the target footprint.
