LM98640QML-SP: Reliability reports

Fiorella Vargas

Part Number: LM98640QML-SP

Hello,

I'd like to better understand what criteria P/N LM98640W-MLS meets to be classified as "Flight RHA (non-SMD part" Grade level? I was not able to find a reliability report or further information about what makes this "flight".

Thank you

    Hello Fiorella,

    TI's space grade products that end in "-MLS" fully meet the space grade QML-V requirements of MIL-STD-38535 with one or two exceptions usually having to do with the lack of a mil standard.  

    In the case of the LM98640, at the time of release of the product there were no standards for testing and qualifying the capacitors used on the product.   The capacitors were qualified per MIL-STD-123, but at the time MIL-STD-123 did not cover that type of capacitor.  For this reason, the LM98640 could not be listed on an SMD.  Otherwise, it fully met the standards.  

    Since then, standards have been developed for the capacitors and the LM98640 has been released on an SMD, fully compliant to QML-V of MIL-STD-38535.   The SMD part number is:  5962R1820301VXC

    Please see the latest copy of the datasheet for more information.
