Questions
Is there a KiCad symbol and footprint for the DP2121KM?
Yes. The symbol is Pinmap_Generic:Q_PMOS_1G_2S_3D and the footprint Package_TO_SOT_SMD:SOT-723, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the DP2121KM?
SOT-723, with 3 pins. Its footprint is drawn on this page.
Where is the DP2121KM datasheet?
Doeshare publishes it: the Datasheet link on this page opens it.
Where can I order the DP2121KM?
JLCPCB lists it as part C2931704, with 0 in stock; the sellers' links on this page open their listings.
What can replace the DP2121KM?
Parts like it in the library: the CJ3134K KF by Jiangsu Changjing Electronics Technology (CJ), the BM3134KE by BORN, the SP2004KT7 by Siliup and the RUM001L02-TP by TECH PUBLIC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
