One table, both lines
This is the consolidated cross-reference we use most often: imported original on the left, in-stock alternative on the right, across the MCU and power-management families.

How to use this table
These are functional alternatives sourced from manufacturer cross-reference data. Treat every row as a candidate, then verify pinout, electrical limits and qualification for your specific design before substituting. The original part is listed for identification only.
Need a row that is not here? The full lists live in the MCU category and the power category, or send the part number through the BOM upload.
Frequently asked questions
Are these guaranteed drop-in replacements?
They are functional alternatives, not guaranteed pin-to-pin identical. Always verify the datasheet and re-validate the design.
How current is the cross-reference data?
It reflects the parts currently in stock on this store; stock and date code are shown on each product page.
Can you add a new cross-reference?
Yes — send us the original part number and we will map it to an in-stock alternative.
