First, I'll suggest the term "aircraft quality" is
without definition but in answer to your question,
there's a major difference between auto-parts-store
versus environmentally qualified terminals recommended
for use on airplanes.
The major feature of a solderless terminal for single
wire termination is the inclusion of a metal liner
inside the plastic sleeve that is supposed to support
the insulation of a crimped wire. The premier terminal
maker (AMP Incorporated) offers both pre-insulated, diamond
grip (PIDG) and all plastic (PlastiGrip) terminals.
Virtually all major terminal manufacturers offer equivalent
parts.
Anyone who goes to the trouble to include this sleeve
has probably taken the time and effort to become a
qualified supplier under one or more of the military
specifications describing the better terminals. When in
doubt, look inside the wire end of the un-crimped
terminal . . . you should see two pieces of metal
inside the plastic insulator. One is the butt end of
the terminal where the stripped end of the wire will
go . . . the other is a thin metal liner inside the
insulator that will extend almost to the open end
of the plastic.
