At 10000 cycles, this plug's gold finish is thick enough to survive twice that many matings — relevant if the cable is the daily connection for a field programmer or a diagnostic tool that gets plugged into a dozen units a shift. The steel and stainless shell/shielding material adds mechanical robustness; the stainless variant resists corrosion from hand oils and mild industrial atmosphere better than a plain nickel shell. If the design can tolerate a current-production USB micro-B plug from the same family, the pinout and footprint are standardised by the USB-IF, so a cross-check against an active TE or equivalent part is worth the time before committing to a last-time buy. Solder-termination plug — the five contacts are soldered to the cable conductors. Free-hanging (in-line) mount terminates the cable end.","metaTitle":"TE 1939054-2 USB micro-B Plug, 5 Contacts, Obsolete","metaDescription":"TE 1939054-2 USB micro-B plug, 5 contacts, USB 2.0, gold contacts, 10000 mating cycles.
