I want to ask the difference between EL357 and LTV354. Can they be directly replaced?

If the pin packages are the same, you need to look at the manual to see what the difference is. They should be interchangeable.

Is it LTV-354T? Except for the package size and pin arrangement, no one can guarantee that they are interchangeable in details.

The biggest difference between the two is that EL357 is unidirectional drive, while LTV-354T is bidirectional and allows the drive current to be as low as ±1mA while still maintaining a CTR of ≧20%.
