Frequently asked questions
- Is the XA3S400A-4FTG256Q still in production?
- No. The XA3S400A-4FTG256Q has been discontinued by the manufacturer. Discontinued parts can still be quoted — send a request with the quantity and any date-code requirements.
- Is there a direct replacement for the XA3S400A-4FTG256Q?
- No. The manufacturer's discontinuation notice states there is no direct replacement for the XA3S400A-4FTG256Q. Either the remaining supply is used, or the board is revised around a current device.
- What package is the XA3S400A-4FTG256Q?
- The XA3S400A-4FTG256Q comes in the FTG256 package (256-FTBGA, 17 × 17 mm).
- Which versions of the XA3S400A come in industrial temperature?
- The XA3S400A-4FTG256Q is an automotive-temperature part (-40 °C to 125 °C, junction), a wider range than industrial. 2 XA3S400A parts are industrial temperature. A different speed grade or package is not a drop-in replacement, so check it against your design.XA3S400A-4FTG256IXA3S400A-4FGG400I
