Questions

Is there a KiCad symbol and footprint for the PCA9535PW?

Yes. The symbol is EasyEDA_Cloud:TCA9535PWR(UMW) and the footprint Package_SO:TSSOP-24_4.4x7.8mm_P0.65mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the PCA9535PW?

TSSOP-24, with 24 pins. Its footprint is drawn on this page.

Where is the PCA9535PW datasheet?

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

Where can I order the PCA9535PW?

JLCPCB lists it as part C3202154, with 6,223 in stock; the sellers' links on this page open their listings.

What can replace the PCA9535PW?

Parts like it in the library: the PCA9555PW by NXP Semiconductors, the TCA9535PW by Texas Instruments, the TCA9555PW by Texas Instruments and the PCA9539PW by NXP Semiconductors. Check their datasheets: a part that fits the footprint may still differ in its ratings.
