Reliability FAQs

Find answers to questions about defective parts per million (DPPM), mean time between failures (MTBF), FIT rate, moisture sensitivity level (MSL) ratings and qualification information.

Where is more information on DPPM/FIT / MTBF?

For a detailed definition on DPPM, FIT, and MTBF, please visit the reliability terminology page. For device-specific DPPM/FIT/MTBF data, please see TI’s DPPM/FIT/MTBF estimator.

Where is MSL rating information found?

Moisture sensitivity level (MSL) determines the floor life before the board mounting once its dry bag has been opened. For specific information regarding a device’s MSL rating, please visit the moisture sensitivity level tool.

Ex. Enter TI part number “OPA333” into the search box, and click search.

Click on the specific part number to see the moisture level of the part.

For more about MSL, please see our MSL ratings application note.


What is TI’s qualification approach?

The qualification process is how we confirm that the reliability of our designs, processes, products and packages meets industry standards. All TI products undergo qualification and reliability testing or qualification by similarity justification prior to release.
