The EP4CGX15BF14C8N is a Cyclone IV GX device with 72 I/O in a different package and 14400 logic elements. The EP4CE22E22C9L has 22320 LEs and 79 I/O in a 144-EQFP. They are not pin-compatible — do not attempt a board-level swap without a full pinout comparison.
The EP4CGX15BF14C8N (Cyclone IV GX) is not a functional second-source — it has fewer logic elements (14400 vs 22320), fewer I/O (72 vs 79), and includes transceivers that the E series lacks. The EP4CE6F17C8N (6272 LEs) and EP4CE40F29C8 (39600 LEs) are same-family density alternatives but require different package footprints. No pin-compatible second-source exists for the EP4CE22E22C9L.
No. The EP4CGX15BF14C8N is a Cyclone IV GX device in a different package with a different pinout. The EP4CE22E22C9L is a 144-EQFP; the GX part uses a different footprint. A board-level swap would require a new PCB layout.
