Overview
The HD40N03 is a MOSFET made by HL in a TO-252 package with 3 pins. -55℃~+175℃ 1 N-channel 108pF 17nC@10V 2.5V 22mΩ@5V 30V 40A 40W 800pF TO-252 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (Pinmap_Generic:Q_NMOS_1G_2D_3S, from PCBKit's generic symbols) and its footprint (EasyEDA_Cloud:TO-252-3_L6.5-W5.8-P4.60-LS9.9-BR, from EasyEDA), ready for a KiCad board. JLCPCB lists it (part C5187563).

Questions
Is there a KiCad symbol and footprint for the HD40N03?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-252-3_L6.5-W5.8-P4.60-LS9.9-BR, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HD40N03?
TO-252, with 3 pins. Its footprint is drawn on this page.
Where is the HD40N03 datasheet?
HL publishes it: the Datasheet link on this page opens it.
Where can I order the HD40N03?
JLCPCB lists it as part C5187563, with 0 in stock; the sellers' links on this page open their listings.
What can replace the HD40N03?
Parts like it in the library: the 1N60L by UMW, the AOD403 by TECH PUBLIC, the AGM14N10D by AGM-Semi and the IRFR024N-JSM by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
