Is there a KiCad symbol and footprint for the 2SD1664-R?
Yes. The symbol is Pinmap_Generic:Q_NPN_1B_2C_3E_4C and the footprint EasyEDA_Cloud:SOT-89-4_L4.5-W2.5-P1.50-LS4.2-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 2SD1664-R?
SOT-89, with 4 pins. Its footprint is drawn on this page.
Where is the 2SD1664-R datasheet?
KEXIN publishes it: the Datasheet link on this page opens it.
Where can I order the 2SD1664-R?
JLCPCB lists it as part C489328, with 123 in stock; the sellers' links on this page open their listings.
What can replace the 2SD1664-R?
Parts like it in the library: the 2SB1188-R by KEXIN, the BCX5616QTA by Diodes Incorporated, the FCX1047ATA by Diodes Incorporated and the H8050D by KEXIN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
