can we create 2 model classes for single table in mvc

but i am not able to do it.. i am getting exception like
The type ****.Models.***** already contains a definition

I am getting error,
I have one table np_user_dtls with 4 fields in sql server

user_name
user_last_name
arabic_name
nationality
In mvc i created a model class as below

public partial class np_user_dtls
{


[Display(Name = "First Name*")]
[Required(ErrorMessage = "First name is required.")]
public string user_name { get; set; }


[Required(ErrorMessage = "last name is required.")]
public string user_last_name { get; set; }

[Required(ErrorMessage = "arabic name is required.")]
public string arabic_name { get; set; }

[Required(ErrorMessage = "nationality is required.")]
public string nationality { get; set; }
}
and in context model i define the relationship between model class and db table as follow

public System.Data.Entity.DbSet<****.Models.np_user_dtls> np_user__dtls { get; set; }
now i need an another class in which arabic name is not mandatory

so i create a model like below

public partial class np_user_dtls_1
{


[Display(Name = "First Name*")]
[Required(ErrorMessage = "First name is required.")]
public string user_name { get; set; }


[Required(ErrorMessage = "last name is required.")]
public string user_last_name { get; set; }


[Required(ErrorMessage = "nationality is required.")]
public string nationality { get; set; }
}
but when i create an entry for this in db context like below

public System.Data.Entity.DbSet<****.Models.np_user_dtls_1> np_user__dtls { get; set; }
its giving me an error

The type ****.Models.***** already contains a definition for np_user__dtls
is it not possible to define multiple model for a single table?
