ASAP Semiconductors customers can browse our extensive stock of both current and obsolete parts though our proprietary website ASAP Aerospace, where parts are catalogued by their respective, federally assigned National Stock Numbers.
To ease the acquisition process, U.S. Department of Defense created a system that distinctively and permanently identifies the items that it purchases. This system, termed the National Stock Number (NSN), consists of 13 digits which are broken down into the 2 ensuing identifying subcategories :
1. Federal Supply Classification Group - The first 4 digits of the NSN identifies the Federal Supply Class code (FSCG).
2. National Item Identification Number - The last 9 digits of the NSN identifies the National Item Identification Number (NIIN).
The FSCG and NIIN can be broken down even further into the following classifying subcategories :
Federal Supply Group - The first 2 digits of the FSCG identifies the Federal Supply Group (FSG).
Federal Supply Code - The last 2 digits of the FSCG identifies the Federal Supply Code (FSC).
National Codification Bureau - The first 2 digits of the NIIN identifies the National Codification Bureau (NCB) or NATO country code.
Item Serial Number - The last 7 digits of the NIIN is merely an item serial number that does not follow an assignment pattern.
