Questions

Is there a KiCad symbol and footprint for the LM5161PWP?

Yes. The symbol is Regulator_Switching:LM5161PWP and the footprint Package_SO:Texas_HTSSOP-14-1EP_4.4x5mm_P0.65mm_EP3.4x5mm_Mask3.155x3.255mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LM5161PWP?

HTSSOP-14-EP, with 15 pins. Its footprint is drawn on this page.

Where is the LM5161PWP datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the LM5161PWP?

JLCPCB lists it as part C468246, with 3,169 in stock; the sellers' links on this page open their listings.

What can replace the LM5161PWP?

Parts like it in the library: the LM3150MHX by Texas Instruments, the LM3150MH by Texas Instruments, the LM3150MHE by Texas Instruments and the LM5156HPWP by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
