The DS2401+ comes in a TO-226-3 / TO-92-3 through-hole package, a three-lead inline format that is a standard footprint for board-level identification. Through-hole mounting suits prototyping, retrofit, or environments where vibration resistance is less critical than ease of hand-assembly and rework.
For BOM planning, the active status means standard lead times apply through distribution channels, with no last-time-buy pressure.
The DS2401+ is the ROHS3-compliant variant of the base DS2401. Both share the same Silicon Serial Number function and TO-92-3 package; the + suffix indicates lead-free / RoHS compliance.
The DS2401+ provides a factory-programmed 64-bit serial number that is read over a single-wire interface. It is designed for applications such as PCB identification, network node registration, and equipment authentication, where each instance must have a unique, non-volatile identifier.
