Questions

Is there a KiCad symbol and footprint for the TF4953B?

Yes. 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 TF4953B?

SO-8L, with 5 pins. Its footprint is drawn on this page.

Where is the TF4953B datasheet?

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

Where can I order the TF4953B?

JLCPCB lists it as part C52287144, with 3,990 in stock; the sellers' links on this page open their listings.

What can replace the TF4953B?

Parts like it in the library: the MCQ07NP03A-TP by Micro Commercial Components, the MDD4407 by MDD, the AO4411(ES) by ElecSuper and the AO4419(ES) by ElecSuper. Check their datasheets: a part that fits the footprint may still differ in its ratings.
