The purpose of Counterfeit Part Investigation is to ensure that parts going into critical applications are of a known or traceable pedigree which have not been subjected to prior use. Counterfeit are parts that have been purposely altered to give a false indication of the parts function or pedigree. The steps of this plan are necessary to ensure complete verification of the parts from an unknown lot or if parts are bought outside of the manufacturers approved network of distributors.
Counterfeit testing is performed to the following industry adopted standards: SAE AS5553 and IDEA-STD-1010A.

Traceable Paperwork When at all possible, parts should have traceability back to the manufacturer. This insurance is the ultimate proof of pedigree. This being said, this paperwork can easily be modified and in most cases is not available through parts brokers who may supply the parts. In the absence of this paperwork it is the responsibility of the user to ensure that parts are genuine.
Electrical Test When electrical test is properly performed, parts can be screened to ensure functionality is within specifications over temperature. While this test does provide information about the functionality of the part it does not provide proof of pedigree. This may pose some issues if one part out of the suspect lot is from an original lot known to have issues. In addition, it may not identify parts that have been previously used or have dormant failures that would shorten the useful life span of the part.
External Visual Inspection External visual inspection is a non-destructive method used to identify evidence which indicates purposeful alterations of the parts. This investigation looks at every aspect of the external package and leads to ensure no evidence of remarking or prior use exist. While this step is considered non-destructive, some parts markings will be tested utilizing solvents appropriate to test the permanency and quality of the part markings. In addition solvent may be used to verify if blacktopping has occurred as a precursor for remarking parts. The following steps are utilized during this step to ensure full investigation of the parts in question.
Photo documentation of parts as received.
- External Visual Inspection of all aspects of the part at a magnification of 10X minimum.
- Looking for Blacktopping
- Looking for scaring on the leads indicating prior use
- Looking for any damage to the package that would indicate prior use
- Looking for ACID etch of the surface of the part
- Looking for any evidence of sanding of the surfaces of the part
- Utilizing solvents to ensure marking permanency
- Acetone Swab
- MIL-STD-883 Method 2015 Resistance to Solvents
- Heated 1-Methyl 2-Pyrrolidinone (180C for 2-5 minutes)
