Procurement Notes
Verify the specific suffix codes against official Everlight documentation to confirm pinout configuration and compliance status. Ensure the component matches the required isolation voltage ratings for the target application circuit. Cross-reference datasheet revisions to confirm parameter consistency before integration into production designs.
Selection Notes
Select this component when high isolation voltage is required for single-channel signal transfer. Consider the NPN output type and surface mount form factor for PCB layout constraints. Verify that the operating temperature range meets the environmental requirements of the final assembly.
Part Context
This part belongs to the EL816 series of transistor output optocouplers from Everlight Electronics. The series is characterized by high isolation capabilities and compact packaging options suitable for modern electronic assemblies. The specific model variant defines the package style and terminal configuration.
Replacement Considerations
Consult official Everlight documentation for confirmed substitute part numbers. Do not assume compatibility with generic optocouplers without verifying pinout and electrical specifications.
