Start from the canonical MPN
Cross-reference works best when you anchor on the exact ordering code from the design. Search it on mpn.cc, open the catalog entry, and review listed alternatives and parameters.

Find drop-in alternatives and cross-references
When an MPN is obsolete, allocated, or on long lead time, you need functionally similar parts — not random keyword matches. mpn.cc surfaces alternatives tied to the resolved part.
Validate before you swap
Pin-compatible does not always mean drop-in. Compare supply voltage, tolerance, temperature range, and package before changing a BOM line — use the spec table and datasheet link on the part page.
