Difference between 66102-9 and 66103-4

Could you please tell me if there is any difference between the two parts?

66103-4 A1342TR-ND and A1342CT-ND 66102-9

To me, they seem identical. Please advise.

The difference between the parts 66103-4 and 66102-9 is the packaging from TE. The part 66102-9 comes on a reel and 66103-4 comes loose in bag.
