## Frequently asked questions about the datasheet library

### What can I download here?

Datasheets and comparison sheets for the HGCHIPS parts in our portfolio. Each file is matched to the original part number it replaces, so you can compare the two side by side before quoting.

### My part number is not here — what should I do?

Send it to [our team](https://hgchips.net/datasheets/contact.html) or look it up in the [cross-reference table](https://hgchips.net/datasheets/cross-reference.html). If we have a matching part we share the sheet; if we do not, we say so rather than offer a part that does not fit.

### Are the specs the same as the original brand?

Density, organization, speed grade, voltage, package and temperature grade are listed per part so you can compare field by field. Tell us the rail and temperature of your board and we confirm whether the substitute applies.
