Procurement Notes
Verify the specific suffix TA indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official documentation. Check current lifecycle status as components may be discontinued or subject to limited availability. Ensure the manufacturer part number matches exactly to avoid pinout mismatches.
Selection Notes
Select this component for designs requiring surface mount isolation with NPN output. Verify that the 5000 Vrms isolation rating meets system safety requirements. Consider the operating temperature range and current transfer ratio specifications for circuit compatibility. Ensure the footprint matches the PCB layout design.
Part Context
This part belongs to the EL817 series of transistor output optocouplers from Everlight. The series offers various packaging options including DIP and SMD variants. The VG suffix typically denotes environmental compliance attributes. The S1 designation refers to the specific lead form geometry for surface mount applications.
Replacement Considerations
Direct substitutes include other EL817 variants with compatible pinouts such as EL817(S1)(C)(TU) or EL817(S1)(B)(TA). Verify isolation voltage and current transfer ratio specifications match before substitution. Ensure the replacement component supports the required surface mount package type.
