Procurement Notes
Verify the specific suffix (e.g., S, X, TA) to confirm package type and compliance status. Ensure the selected variant matches the required isolation voltage and current transfer ratio specifications. Confirm RoHS compliance and safety approvals such as UL or VDE are present in the datasheet for the exact part number. Check lead spacing requirements for PCB layout compatibility.
Selection Notes
Select based on required isolation voltage and current transfer ratio. Consider package type availability for manufacturing processes. Verify operating temperature range meets application demands. Ensure input forward current and output collector current ratings align with circuit design. Check for necessary safety certifications for end-product compliance.
Part Context
The EL816 belongs to the EL816 series of photo couplers manufactured by Everlight Electronics. This series includes various variants with different packaging and compliance markings. The devices are designed for general-purpose isolation applications. They utilize infrared LED technology for optical coupling. The series offers multiple package options to suit different assembly needs.
Replacement Considerations
Direct substitutes include other EL816 series variants with matching electrical characteristics. Variants may differ in package style or compliance markings. Verify pinout compatibility before substitution. Ensure isolation voltage and current transfer ratio meet original design requirements.
