Frequently asked questions
How does this compare to the 6ES7307-1KA01-0AA0?
The 6ES7307-1KA01-0AA0 is a different class of part — a power supply module for the S7-300 series, not a communication processor. They are not functionally interchangeable; one is for the S7-400 rack, the other for S7-300. If you are sourcing for an S7-400 backplane, the 6ES7443-5DX02-0XE0 is the correct fit.
