In general, any 10811 with an edge card type connector in interchangeable in any instrument, in terms of basic functionality. The only differences are that various part numbers in the 10811 family are selected for certain critical specs. Certainly, between the 5334 and 5335, they are interchangeable. OTOH, an instrument like the 8662A might not meet phase noise without the "official" version of 10811.
A 10811 also must work in any 10544 socket, although the reverse isn't necessarily true. The 5334A (as opposed to the 5334B that I was the project manager on) has a poorly regulated power supply that causes the oven power voltage to drop to only +12V during warmup, which is supposedly below the +15V minimum and the +20V nominal. It turns out that +12V is sufficient to cause the oven to warm up. It is not sufficient to operate the oven well in a steady state. However, once the oven current cuts back, the power supply voltage goes back up to over 15 volts so everything works. I fixed this problem in the 5334B. I don't know if the 5335 has a similar problem.
