Error at Data Flow Task[OLE DB Destination [36]]: Column "Name" cannot convert between unicode and non-unicode string data types

I am working on SSIS and i am importing excel data into tables. And i am using

Data flow task->Excel Source->Lookup->Multicast->OLE DB, OLE DB, OLE DB.

When i want to run the package, i am getting below error.

I cant use Data conversion.

Actually, When i used data coversion, its working fine. And in tables, i chnaged the data type into nvarcha(100). Then also its worked fine.

I need to solve this issue, when my database columns datatypes are in varchar and without using Data conversion.
