| MTBCF VS MTBF Can MTBCF (Mean Time Betwen Critical Failure) be greater than MTBF (Mean Time Between Failure) assuming same system, temperature and environment? |

| Joseph, Typically MTBCF is a subset of MTBF since every system failure is not considered critical. Therefore, the MTBCF value would be larger than the MTBF value. If every system failure has been defined as critical then MTBCF and MTBF would be the same. MTBF will never be greater than MTBCF |

| Thank you. That was my conclusion also. However someone told me MTBCF is looking at redundant circuitry whereas MTBF Take cares of series circuitry. Therefore MTBCF could sometime be greater than MTBF. I just could not think of any example that could make that statement true. |

| In Fact we Have 2 customers who sent us proposal with MTCBF lower than MTBF. Before correcting them i wanted to make sure there are no instances where MTBF could be larger than MTBCF. |

| This also holds true for MTTR (Mean Time To Repair); there will never be an instance when a Maintenance/Repair value is larger than the program level MTTR. |
