Product details

The solder termination suits it for overmoulded cable assemblies or direct wire attachment in a harness build. Rated for 30 V and a multi-rate current profile — 0.5A, 1A, and 1.8A — the three-tier current rating reflects the standard USB 2.0 power delivery scheme: 0.5A for low-power devices, 1A for charging ports, and 1.8A for higher-drain peripherals. The 10,000 mating cycle rating is well beyond the typical USB micro-B spec (usually 5,000 to 10,000 cycles), making this plug a candidate for applications where the cable is frequently plugged and unplugged — field-service tools, test fixtures, or portable equipment. The shell is steel and stainless steel, providing the mechanical strength to withstand repeated insertion into a receptacle without cracking the housing.

If a drop-in replacement is needed, the buyer should verify the mating receptacle and board footprint before substituting; no pin-compatible alternative is documented in the available records.

Frequently asked questions

What is the replacement for 1-1939054-2?

Any substitution must be validated against the mating receptacle and board layout — the 5-contact micro B form factor is standard, but pin assignment and shell dimensions vary by manufacturer.
