An electrical connector having a leadframe housing, a first electrical contact fixed in the leadframe housing, a second electrical contact fixed adjacent to the first electrical contact in the leadframe housing, and a third electrical contact fixed adjacent to the second electrical contact in the leadframe housing is disclosed. Each of the first and second electrical contacts may be selectively designated, while fixed in the lead frame housing, as either a ground contact or a signal contact such that, in a first designation, the first and second contacts form a differential signal pair, and, in a second designation, the second contact is a single-ended signal conductor. The third electrical contact may be a ground contact having a terminal end that extends beyond terminal ends of the first and second contacts.
