## Frequently asked questions about DDR3 replacement

### Which DDR3 densities and organizations do you cover?

1, 2, 4 and 8 Gbit across organizations from 64Mx16 to 1Gx8, speed grades DDR3-1066 to DDR3-2133, at 1.35 V and 1.5 V, in VFBGA-96.

### Can a 1.35 V DDR3L part replace a 1.5 V DDR3 part?

Not without checking the target design. Voltage is one of the fields we confirm before quoting, so tell us the rail of your board and we will tell you whether the substitute applies.

### How many DDR3 part numbers do you cross-reference?

57 DDR3 part numbers today. Use the [cross-reference table](https://hgchips.net/cross-reference.html) and filter to see them, or send your part number.
