Procurement Notes
Verify the specific suffix designation against the manufacturer's current datasheet to confirm pinout and packaging details. Ensure compliance requirements match project specifications. Confirm availability status as distribution channels may vary. Cross-reference part numbers with official Everlight documentation to avoid substitution errors.
Selection Notes
Select this component when surface-mount technology is required for optocoupler applications. Consider the 5000 Vrms isolation rating for safety-critical designs. Verify thermal management needs given the operating temperature range. Compare current transfer ratio specifications against circuit requirements for adequate signal transmission.
Part Context
This component belongs to the EL817 series of optocouplers from Everlight Electronics. The series includes various package options such as DIP and SMD configurations. The EL817(D)-VG specifically denotes the surface-mount variant within this family, maintaining the core electrical characteristics of the standard EL817 line while adapting to modern PCB assembly techniques.
Replacement Considerations
Consult official Everlight documentation for verified substitute part numbers. Generic equivalents may not match isolation ratings or safety certifications.
