Issue with Balance Data Distributor dll

I have a package with BDD component. I have tried to run this package in SQL Server 2012 after placing the TxBDD.dll (belongs to SQL Server 2014) in pipeline components. It shows error as "The managed pipeline component "Microsoft.BDD" could not be loaded.  The exception was: Could not load type 'Microsoft.BDD' from assembly 'Microsoft.SqlServer.PipelineHost, Version=11.0.0.0, Culture=neutral, PublicKeyToken"

Now I replaced the TxBDD.dll with SQL Server 2012 TxBDD.dll still getting the same error.

I have compared this package with one of my working package. The difference is "componentClassID". The failing package contains componentClassID="Microsoft.BDD" and working package contains componentClassID="DTSTransform.BalancedDataDistributor.2"

So I have replaced my failing package's classid with DTSTransform.BalancedDataDistributor.2 and run with SQL Server 2012 TxBDD.dll this time the package executed successfully but not working with SQL Server 2014 TxBDD.dll.

Please clarify the following if anyone knows.

1. Is BDD require specific version of TxBDD.dll to run in different SQL Server ? 
2. What is the purpose of componentClassID.
3. Why the classid is differs like Microsoft.BDD and DTSTransform.BalancedDataDistributor.2 for same component?

Thanks in advance.
