ASAP Semiconductor customers can view our huge registry of both in-production and obsolete parts, catalogued by their respective National Stock Numbers, via our proprietary website ASAP Aerospace.
To regulate the acquisition process, U.S. Department of Defense created a system that distinctively and permanently identifies the items that it purchases. This system, called the National Stock Number (NSN), is made 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.
