I think for FPGA < gen10 it is easy to replace AS flash and then find other grades (and much lower prices).

EPCS replacement:

EPCQ replacement:

N25Q256A13ESF40G (EPCQ256 replacement) works fine for me with Arria V (ASx1 for me, but ASx4 probably works too).

Or S25FL164K0XMFI00 (EPCS64 replacement) with older FPGA.

I just disabled EPCX ID check and everything works.

But for gen 10 FPGAs, I don't know much yet about EPCQ-L.

In the past with SOIC packages it was easy to unsolder and try parts, but now with this FBGA24 package, it will be harder...

As EPCQ-L models cost ~40€ to 170€, I guess alternatives already exists !
