I am replacing all electrolytic capacitors in an old CB radio but can't find a local source for this capacitor. Is there another type I can use in its place? Does it have to be an electrolytic type? Thanks.

\$\begingroup\$ Yeash...You can buy bags of 1,000 for a few dollars from Digikey/Mouser/Allied, etc. Stay with ceramic SMD for such low values. \$\endgroup\$– user105652Commented Mar 21, 2018 at 0:21

0.1 uF electrolytic caps are already or are almost obsolete
The lower cost solid Radial 0.1uF Tantalums have poor ESR (12~26 ohm)
Radial ceramics are fine. https://www.digikey.ca/product-detail/en/vishay-bc-components/K104K15X7RF53L2/BC3324-ND/2820506 $10 / 100pc
