Procurement Notes
Verify availability status carefully as this specific part number has been marked as obsolete or discontinued by distributors. Confirm if replacement models are available through official channels. Ensure that any substitute components meet the original electrical specifications and physical footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component only if legacy compatibility is required. Due to its discontinued status, engineers should evaluate alternative inductors with similar inductance values and current ratings. Check datasheets for equivalent packages and thermal performance to ensure seamless integration into existing designs without redesigning the PCB layout.
Part Context
This component belongs to the HA65A series of surface mount power inductors produced by TT Electronics/BI Magnetics. The series was designed for high-current applications requiring shielded magnetic cores. The manufacturer has announced the end of life for this series due to material discontinuance, affecting long-term supply chain stability for these specific part numbers.
Replacement Considerations
The HA65A series has been officially discontinued. No direct public substitute part numbers are confirmed in the provided documentation. Engineers must identify equivalent components from other manufacturers or newer series within the same family that match the 3.3µH inductance and SMD package dimensions.
