New Century Components (NCC) has the most superior on-line catalog and resource site in the Aviation
and Defense Industry. Our Master Cross Reference Database (MCRD) and Master Cross Reference Library
(MCRL) will help you identify alternates to a National Stock Number (NSN) or to a Manufactures Part
Number (MPN).
We offer you multiple ways to search for part information. You may search by NSN, Part
Number, or use the NSN Drill Down function.
NSN Catalog
The NSN Catalog allows you to narrow down into the different Federal Supply Classes (FSC). The first column is the FSC Base number of an NSN. The second column is the number of items that are categorized under the FSC Base. And the last column is the title of the category for each of the FSC's.

The second column is the number of parts that are categorized under the FSC Base. And the last column is the title of the category for each of the FSC’s (FSC Base Title).
