FSG 66 Instruments and Laboratory Equipment

Our clients know that we at ASAP Semiconductor pride ourselves in being able to uphold the federal standards of conducting business as a supplier for the Aerospace, Aviation, Military and Defense industries. Buyers 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, the 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).

For example, an existing actuator assembly we supply at ASAP Semiconductor has a 13-digit NSN of 6610-00-001-2516. The FSCG is represented by 6610, and the NIIN by 000012516.

Continuing on, the FSCG and NIIN can be broken down even further into the following classifying subcategories:

  1. Federal Supply Group - The first 2 digits of the FSCG identifies the Federal Supply Group (FSG).
  2. Federal Supply Code - The last 2 digits of the FSCG identifies the Federal Supply Code (FSC).

    For the above actuator assembly, the FSG is represented by 66, and the FSC by 10.

  1. National Codification Bureau - The first 2 digits of the NIIN identifies the National Codification Bureau (NCB) or NATO country code.
  2. Item Serial Number - The last 7 digits of the NIIN is merely an item serial number that does not follow an assignment pattern.

For the above actuator assembly, the NCB is denoted by 00, USA’s country code.
