This has been discussed in the K3S FAQ. See the link to it on the main Elecraft.com web page. Here's the detailed answer from it.
Q: Can I move the KPA3 100-watt PA module from my K3 to a K3S, or do I need the new KPA3A module? A: A KPA3 can be used in a K3S. However, we recommend using the KPA3A PA module, because the K3S RF board was optimized for use with the KPA3A's MOSFET power transistors. In a K3S, a KPA3A will typically provide 1 to 3 dB better transmit IMD performance, on average, than a KPA3. Hope that helps.
