compatible with Single and Double build copper magnet wire 18 through 34 AWG (1.02 through 0.16
mm). Unless otherwise specified on the Tyco Electronics Customer drawing, connection is to be made
to an individual magnet wire or solid bare copper wire.
1.2. Qualification
When tests are performed on the subject product line, procedures specified in Figure 1 shall be used.
All inspections shall be performed using the applicable inspection plan and product drawing.
1.3. Successful qualification testing on the subject product line was completed on 04Dec09. The
Qualification Test Report number for this testing is 501-723. This documentation is on file at and
available from Engineering Practices and Standards (EPS).

4. QUALITY ASSURANCE PROVISIONS
4.1. Qualification Testing
A. Specimen Selection
Specimens shall be prepared in accordance with Application Specification 114-13166 and shall be
selected at random from current production. Each test group shall consist of 30 terminals (15
interconnected bobbin assemblies) with the smallest and largest magnet wire size.
B. Test Sequence
Qualification inspection shall be verified by testing specimens as specified in Figure 2.
4.2. Requalification Testing
If changes significantly affecting form, fit or function are made to the product or manufacturing process,
product assurance shall coordinate requalification testing, consisting of all or part of the original testing
sequence as determined by development/product, quality and reliability engineering.
