Procurement Notes
Verify the specific suffix requirements for your assembly line, as packaging variations exist within the EL817 family. Confirm that the S1 designation matches your PCB footprint requirements. Ensure compatibility with your reflow soldering profile if using the tape and reel variant. Check current lifecycle status as availability may vary by region.
Selection Notes
Select this component when a surface mount solution is required for signal isolation. The S1 type indicates specific lead bending suitable for surface mounting. Consider the CTR range and collector-emitter breakdown voltage to ensure it meets circuit switching requirements. Verify insulation voltage ratings against regulatory standards for your application environment.
Part Context
This part belongs to the EL817 series of photocouplers from Everlight Electronics. The series includes various package options such as DIP and SMD types. The S1 variant specifically denotes a surface mount configuration with bent leads. The TA suffix typically indicates tape and reel packaging for automated placement.
Replacement Considerations
Direct substitutes include other EL817 variants with compatible pinouts such as EL817(S1)(TU) or EL817(S1)(C)(TU). Verify that replacement parts match the surface mount footprint and electrical characteristics like CTR and isolation voltage before integration.
