Part Number: UC1707-SP

Dear TI experts, 

According to SMD document(5962-87619), UC1707-SP have 4 class(M, Q, N,V) according to PIN.

But how can i tell them apart between Class M and Q? 

I want to know the class '5962-8761901EA'.

Best regards

sooyeon

    Sooyeon,

    the easiest way to see this, is to look at the SMD drawing.

    This information is in section 1.2.  Essentially device type 01 is M and Q, and device type 03 would be class  N or V.

    You can access the SMD from the DLA website.  Here is direct link to pdf.

    Sooyeon,

    I was able to get an answer.

    One Part – One Part Number System

     

    DLA allows marking of microcircuits under a One Part - One Part Number system.  Following is an excerpt from a Standard Microcircuit Drawing (SMD):

    One Part - One Part Number System: The one part - one part number system described below has been developed to allow for transitions between identical generic devices covered by the four major microcircuit requirements documents (MIL‑H‑38534, MIL‑I‑38535, and 1.2.1 of MIL‑STD‑883) without the necessity for the generation of unique PIN's. The three military requirements documents represent different class levels, and previously when a device manufacturer upgraded military product from one class level to another, the benefits of the upgraded product were unavailable to the Original Equipment Manufacturer (OEM), that was contractually locked into the original unique PIN. By establishing a one part number system covering all three documents, the OEM can acquire to the highest class level available for a given generic device to meet system needs without modifying the original contract parts selection criteria.

     

    Therefore a part previously released as Class M would now be built as Class Q without requiring a change to the orderable part number or the part marking.
