Excellent electrical upgrade with higher current and lower DCR in a compact SMD package. Requires board redesign.
Finding a replacement for the PDPTAT0608-4R7M 4.7µH power inductor involves considering SMD alternatives, as direct DIP replacements are uncommon. Key parameters to match are the 4.6A current rating and 4.8A saturation current.
Requires PCB redesign from DIP to SMD.
Multiple candidates offer superior current handling and similar or better DCR.
No direct drop-in replacement exists due to the target's DIP package. All alternatives are SMD and require a board redesign.
FEXL0660A-4R7M offers a full electrical upgrade in a smaller SMD footprint, ideal for new designs or revisions.
Package mismatch (DIP vs. SMD) is the main risk, making a board redesign mandatory.
