Device identity and key spec
The DS2401+T&R is a silicon serial number IC from Analog Devices, purpose-built to provide a unique, factory-lasered 64-bit registration number for equipment and network node identification. It is housed in a TO-226-3 / TO-92-3 (TO-226AA) package with formed leads, through-hole mount, making it a drop-in for legacy board layouts that already use this footprint.
Lifecycle and compliance
RoHS3 compliant, with no lead or restricted substances above the threshold — no special handling or exemption paperwork needed for EU-market equipment.
Sourcing and packaging options
No stock-holding claim — confirmed per RFQ.
