Procurement Notes
Verify the specific manufacturer part number against official TT Electronics/Optek Technology documentation to ensure authenticity. Confirm that the component meets required RoHS compliance standards for your region. Check datasheet revisions for any updates regarding pinout or electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when a single-channel isolation solution with a standard TO-72-4 footprint is required. Ensure the application demands a current transfer ratio between 30% and 200% and can accommodate a 10 mA forward drive current. Verify that the 30 V collector-emitter voltage rating aligns with the load requirements.
Part Context
This component belongs to the Optokoupler family produced by TT Electronics/Optek Technology. It is designed for general-purpose isolation tasks where space efficiency and reliable signal transfer are prioritized. The TO-72-4 package allows for easy integration into through-hole PCB designs common in legacy and industrial equipment.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Cross-reference electrical parameters such as CTR range and isolation voltage when evaluating alternative components.
