Gold vs tin — contact finish choice
The 926902-3 carries gold contact finish, while the 926902-1 is the tin-finished sibling for the same 13-15 AWG wire gauge and split-pin design — gold suits higher mating-cycle or corrosive-environment duty. For a socket counterpart in the same wire range, the 926901-1 provides a tin-finished socket; the 926898-1 covers 14-20 AWG with tin finish.
