Questions

Is there a KiCad symbol and footprint for the KA2903D?

Yes. The symbol is EasyEDA_Cloud:LM293AM_TR and the footprint Package_SO:SO-8_3.9x4.9mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the KA2903D?

SOIC-8, with 8 pins. Its footprint is drawn on this page.

Where is the KA2903D datasheet?

onsemi publishes it: the Datasheet link on this page opens it.

Where can I order the KA2903D?

JLCPCB lists it as part C3658686, with 0 in stock; the sellers' links on this page open their listings.

What can replace the KA2903D?

Parts like it in the library: the LM293DR-HXY by HXY MOSFET, the TSX3702IYDT by STMicroelectronics, the AS393AMTR-E1 by Diodes Incorporated and the MAX922ESA+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
