Hi,

If you are looking for a device with operating temperature range - 40 C to +125 C, then the recommended replacement will be CY15B128Q-SXE. Please see the datasheet for this device attached with this response.

CY15B128Q-SXA and FM25V01A are similar devices. But, CY15B128Q-SXA is qualified for Automotive applications within temperature range –40C to +85C (Automotive-A grade).

Thanks and Regards,

Sudheesh
