USB 2.0 Mini B Plug for Cable Assemblies — 5000 Mating Cycles
What the 5000-Cycle Rating Means for the Build
The gold contact finish supports that cycle life without the galling or oxidation you'd see on tin-plated contacts after a few hundred cycles. The steel shell gives the body mechanical toughness, but note the connector is unshielded — if your cable run passes through a noisy environment, pair it with a shielded cable and add ferrite clamping rather than relying on the connector body for EMI containment.
Cross-Reference: UX40A-MB-5P
The UX40A-MB-5P carries identical specs — same 5 contacts, same 1 A / 30 VAC rating, same gold plating, same 5000-cycle life, same unshielded steel shell. The only difference is the base product number (UX40A vs UX40). If you're sourcing and the UX40-MB-5P lead time is long, the UX40A-MB-5P is a functional drop-in for the BOM line — confirm the physical outline matches your cable overmold tooling before committing.
