Is there a KiCad symbol and footprint for the RSFD2503C?
Yes. The symbol is EasyEDA_Cloud:SA0716122G65AT and the footprint EasyEDA_Cloud:FILTER-SMD_8P-L1.8-W1.4_RSFDXXXXC, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the RSFD2503C?
SMD,1.4x1.8mm, with 8 pins. Its footprint is drawn on this page.
Where is the RSFD2503C datasheet?
ROFS publishes it: the Datasheet link on this page opens it.
Where can I order the RSFD2503C?
JLCPCB lists it as part C2839253, with 0 in stock; the sellers' links on this page open their listings.
What can replace the RSFD2503C?
Parts like it in the library: the RSFD1702C by ROFS and the D5DA740M0K2L4-Z by Taiyo Yuden. Check their datasheets: a part that fits the footprint may still differ in its ratings.
