## Frequently asked questions about ADI µModule replacement

### Which ADI modules do you replace?

LTM46xx (21 part numbers) and LTM80xx (8 part numbers), mapped to HGCHIPS equivalents named HG46xx and HG80xx. Send the exact LTM part number and we confirm the match.

### Do you also supply original ADI stock?

Yes. Original ADI stock, for example LTM3605, is supplied as the original part, not as a replacement.

### How is compatibility confirmed for a power module?

Per original part number: we confirm the pin-out, the package and the electrical comparison, and quote the matching HGCHIPS part.
