Procurement Notes

Verify the specific manufacturer source as this component is produced by both Renesas Electronics and CEL. Confirm RoHS compliance status and packaging type (tube or reel) against your bill of materials. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this part when dual-channel isolation is required in a compact surface mount footprint. Ensure the input forward current and output collector current requirements align with the specified limits. Verify that the 5000 Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This component belongs to the PS2561 series of single and dual channel optocouplers. The 'L' suffix indicates a lead-bending type suitable for surface mount technology. It serves as a cost-effective solution for galvanic isolation between low-voltage control circuits and higher-voltage loads.

Replacement Considerations

Cross-reference with PS2561L2-1-F3-A from Renesas for equivalent specifications. Verify pinout compatibility and package dimensions before substitution.
