Questions

Is there a KiCad symbol and footprint for the NE555D?

Yes. The symbol is Timer:NE555D 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 NE555D?

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

Where is the NE555D datasheet?

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

Where can I order the NE555D?

JLCPCB lists it as part C7593, with 126,413 in stock; the sellers' links on this page open their listings.

What can replace the NE555D?

Parts like it in the library: the NE555P by Texas Instruments, the SA555P by Texas Instruments, the NE556N by Texas Instruments and the LM555CMM by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the NE555D?

225 boards in 187 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
