Procurement Notes
This component is scheduled for obsolescence and will be discontinued by the manufacturer. Availability may be limited or restricted to specific regions depending on distributor inventory. Verify end-of-life status and final purchase dates through authorized channels before integration into new designs.
Selection Notes
Select this part only if legacy compatibility or existing design constraints require the #A921CY series. Due to its discontinuation status, alternative components should be evaluated for future-proofing. Ensure that the 2524 footprint and electrical parameters meet the system requirements without relying on obsolete supply chains.
Part Context
The #A921CY series represents Murata's metal alloy power inductors, characterized by low DC resistance and high current handling capabilities. This specific model belongs to the line choke category, offering shielding to reduce magnetic field emissions. It is distinct from the DFE series due to its specific winding and core material composition.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Given the obsolescence status, engineers must identify cross-reference components based on matching electrical specifications and mechanical dimensions independently.
