DigiKey has information on UVR2G4R7MPD1TD, but what is the difference between this one and UVR2G4R7MPD1CA?
The TD and CA are codes that determine the style and length of the radial leads.
The only difference will be the length of the leads. CA will have leads cut to a 5mm length. TD will have longer leads so it can be mounted on a tape carrier for the Tape & Box packaging.
