How to find an electronic component cross reference
Updated 2026-10-26 · Compiled with AI and reviewed against the linked sources.
A replacement search starts with an exact identity. Record the complete part number, its suffixes and the specific manufacturer or business division. Similar-looking codes can describe different products.
Enter the part number in ExactCross, then inspect the recorded alternatives and their source notes. Manufacturer names help distinguish identical codes used by different suppliers. Use the original source and current manufacturer documentation to understand what the reference actually claims.
A recorded cross reference is a research candidate. It does not by itself establish current stock, identical specifications, safety approval or suitability for your application. Some references describe a series rather than a fully specified orderable part.
Before selecting a replacement, compare the requirements that matter to your application against current documents. Preserve any stated differences and unresolved checks. An empty notes field does not prove that the specifications match.
If ExactCross has no recorded alternative, use Request a cross and provide the exact code, manufacturer and public documentation where available. Research requests are first checked for public part identity. Research has a target turnaround rather than a guarantee of finding an equivalent.
