Questions

Is there a KiCad symbol and footprint for the NA555D?

Yes. The symbol is Timer:NA555D and the footprint Package_SO:SOIC-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 NA555D?

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

Where is the NA555D datasheet?

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

Where can I order the NA555D?

JLCPCB lists it as part C128415, with 4,662 in stock; the sellers' links on this page open their listings.

What can replace the NA555D?

Parts like it in the library: the NE555D by Texas Instruments, the NE555DR by UMW, the NE555DR-JSM by JSMSEMI and the LM555CM/TR by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the NA555D?

11 boards in 8 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
