Questions
Is there a KiCad symbol and footprint for the CJA9451?
Yes. The symbol is Pinmap_Generic:Q_PMOS_1G_2D_3S and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CJA9451?
SOT-89-3L, with 3 pins. Its footprint is drawn on this page.
Where is the CJA9451 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the CJA9451?
JLCPCB lists it as part C24254, with 942 in stock; the sellers' links on this page open their listings.
What can replace the CJA9451?
Parts like it in the library: the UT3N06G-AB3-R by UTC, the NCE0103M-ES by ElecSuper, the 3401P-MS by MSKSEMI and the 3400Q by HL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
