I’m buying some RCM3700 and my supplier asks me wether to take the 20-101-0674 or the 20-101-1305.

At first sight, I don’t see any differences. Can you tell me if there are any of relevance?

20-101-1305 is the new part number instead of 20-201-0674, but the modules are same. If you want to buy the 20-201-0674, you will go for part number 20-101-1305.
