Hi,
As for now, the alternative part for EPCQL1024F24IN is Micron MT25QU01GBBB8E12-0SIT.
For your additional information, you need to enable MT25Q support into your quartus.ini file in order to have the selection of Micron parts in Quartus Prime. You can enable MT25Q support by adding the following variable into your quartus.ini file within the project directory:
pgm_allow_mt25q=on
For more details regarding to enable MT25Q support, please refer to following link:

Thank you.
