Tab width and wire range
The 5-160491-2: It accepts 13-17 AWG wire and terminates with a crimp, using tin-plated brass contacts for the mating interface.
Comparing tab widths across the Faston series
Within the Faston series the 5-160491-2's 0.187" tab width sits between the 0.205" of the 170180-2 and the 0.250" of the 1-160304-0 — the tab thickness, contact finish, and insulation are shared across the three, so the tab width and wire gauge range are the selection axis.
