Is the Siemens 6ES7138-4CA01-0AA0 discontinued?

Source: ECS lifecycle assessment, based on ECS's internal lifecycle data in Command Centre. Last checked . Always confirm a specific part's status with the manufacturer before buying or planning a migration.
What Cancellation means for you
You can no longer order it as a normal product, and nothing new should be designed around it. If machines depend on it, you want spare stock you can rely on and a migration plan. Both start with knowing how many you run.
Before replacing it
A replacement decision starts with understanding how the existing machine uses the part, not simply finding something with a similar specification. We would document the electrical interfaces, configuration, software dependencies and surrounding components before choosing an alternative.
That establishes whether the part can genuinely be swapped or whether the change reaches into a wider section of the control system, and turns an obsolete-spare problem into a planned engineering task with a tested recovery route.
