Is there a KiCad symbol and footprint for the 1N4148W?
Yes. The symbol is Diode:1N4148W and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the 1N4148W?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the 1N4148W datasheet?
HT publishes it: the Datasheet link on this page opens it.
Where can I order the 1N4148W?
JLCPCB lists it as part C179717, with 2,585 in stock; the sellers' links on this page open their listings.
What can replace the 1N4148W?
Parts like it in the library: the 1N4148W-T4 by ZRE, the BAS21GW by Nexperia, the 1N4148W by powersilicon and the 1N4148W by YFSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
