EOL of our module series is normaly as long as Xilinx and Intel will offer the FPGA/SoC:
Passive components (resistors, capacitors) can be changed on the modules without notification. We use different manufacturer and best prices, but in any case the characteristics which are specified in the schematics are the same.
In case other active components will be not longer available, we will replace with footprint compatible equivalent alternatives or we update the PCB to support a equivalent alternatives variant. In case we change such a component, we will create also a new article number, so that you can directly see that something was be updated and we write a PCN
