There is a good chance that this part is composed of partially recycled plastics, considering Panasonic's goal of increasing reuse of resins and other materials.

Unfortunately, significant reductions in mechanical properties occur after replacing virgin PC by recycled PC in the PC:ABS mixture. The Izod Impact strength drops off sharply once recycled PC is substituted into the PC-ABS blend, according to the linked research.

A 50:50 blend of recycledPC:ABS results in a 43.61 J/m impact strength, while a 50:50 pure PC-ABS blend has an impact strength of 253 J/m, 5.8x stronger. A table copied from the referenced study is included here for convenience.

Taking this information into account, it makes sense that the part did not fail FEA simulation. The included material properties did not accurately represent the part and the impact resistance and tensile strength of the analyzed part far exceeded the properties of a recycled PC:ABS part.
