scope:

The purpose of this standard is to:

a. Provide contractors, Original Equipment Manufacturers (OEM's), program offices and the acquiring activity with a substitution list between existing source or specification control drawing (SCD) numbers and standardized military drawing and military specification numbers covering microcircuits used in military applications.

b. Control and minimize the variety of microcircuits used by military activities in order to facilitate effective logistic support of equipment in the field.

This standard establishes a substitution list for microcircuits used in the manufacture and support of military equipment. This document reflects the OEM's and the Department of Defense's (DoD's) determination of substitutability and may be used on production contracts, follow-on contracts, production modifications, logistic support, etc., after parts control procedures (if required) have been followed. The standard military devices, JAN and SMD, listed herein are declared to be substitutable with the corresponding existing contractor or OEM source or specification control drawing (SCD) and the corresponding generic numbers. Program offices and users substituting devices from this list are advised to have their engineering staffs ensure the substitution is appropriate to the specific system or piece of equipment. These organizations are responsible for device performance/reliability verification, and must assume production and operational risks resulting from the substitution.
