Procurement Notes

Verify the specific suffix (TA-V) against the latest Everlight datasheet to confirm pinout and packaging details. Ensure compatibility with surface-mount assembly processes. Check for any recent product change notifications regarding material or process updates that may affect long-term supply or specifications.

Selection Notes

Select this component when high-speed digital isolation is required in a compact form factor. The 1 Mb/s speed suits most standard serial communication protocols. Consider the 5000 Vrms isolation rating for safety-critical applications. Verify that the phototransistor output type aligns with the receiving circuit's input requirements.

Part Context

This part belongs to Everlight's high-speed optocoupler series designed for reliable digital signal isolation. It serves as a surface-mount alternative to through-hole DIP variants like the EL4502. The family focuses on balancing speed, isolation voltage, and physical footprint for modern electronic designs.

Replacement Considerations

Cross-reference with EL4502S(TB)-V for different packaging options within the same functional family. Verify compatibility with other 1-channel, 1Mb/s SMD optocouplers if sourcing constraints exist.
