Gives guidance on the substitution of electronic components used in the manufacture of electronic equipment. Intended for use by both procurement personnel and design personnel. Includes guidance on those components for which it is safe to use "better than" characteristics, as well as on those for which it is not safe. Also gives guidance on how to deal with changes in the quality approval systems applicable to electronic components.

This Published Document gives guidance on the substitution of electronic components used in the manufacture of electronic equipment. It is intended for use by both procurement personnel and design personnel. It includes guidance on those components for which it is safe to use “better than?? characteristics, as well as on those for which it is not safe. Examples of each type of component family are given (e.g. resistors, integrated circuits). Guidance is also given on how to deal with changes in the quality approval systems applicable to electronic components.

Annex A gives details of organizations which are currently considering the subject of obsolescence.

Possible sources of supply for some semiconductors which are no longer available from the original manufacturers are given in Annex B.

This Published Document is not intended for use by maintenance personnel for replacement of defective components in the field, although some of the guidance may be helpful.
