The 6ES7314-1AE02-0AB0: The official successor is the 6ES7314-1AE03-0AB0. That part carries the same S7-300 form factor and 24 V DC supply but with updated firmware and a higher working memory — 48 KB instead of 24 KB. If your application can absorb the memory bump and the firmware revision, that is the cleanest drop-in replacement. If not, the EOL unit remains available through the surplus channel.
