Cross Reference Part Search

The Digi-Key Cross Reference Part Search allows a user to at a glance search for direct replacements, similar product and manufacturer recommended replacement parts. To try it out go to and enter a manufacturer part number in the search box. When you search it will compare that part out to the everything in our database and help you find a suitable replacement part with stock.

The “direct” match type are substitutes that have been verified to have a high probability of being a good replacement for the out of stock part. The green boxes in the results fields will highlight the parameters that match the original part numbers exactly. The results columns can be used to sort by attribute, and can also be repositioned by dragging to highlight the parameters of interest.
The “similar” match may be a good replacement, but will have minor differences that will need to be reviewed before confirmation that the part will work.
The “manufacturer recommended” cross type is one in which the manufacturer of the original part has recommended a replacement. The parametric differences will vary depending on the part itself.
To the left of the datasheet and materials icons you can select and compare specific product to each other.
By selecting multiple parts and comparing you will then be given the option to hide the shared attributes to easily be able to distinguish the differences in the parts.
As with any and all crosses, verification from looking at the datasheets is the only sure way to confirm the suitability of a parts status as a replacement, but the cross reference part search tool will allow the user to dial in quickly as to if a part will work for them or not.

The TechForum Cross Reference category is for parts that Digi-Key does not sell or parts that have gone obsolete. Our Engineers and Techs have reviewed the specifications for these parts and made a recommendation for a replacement. Please review the suggested part to ensure it will work for your application.
