LM120: Need PDN (Part Discontinuation Notice) for obsolete LM120K-5.0 version of base part and also need its replacement or a cross

Daniel Rapp

Part Number: LM120
Other Parts Discussed in Thread: UA79

To TI Support Team:

The customer is interested in TI p/n  LM120K-5.0,  which appears to have been obsoleted. We need verification that it is obsolete -- we need its PDN (Part Discontinuation Notice) and we also need its replacement or a cross. I would offer p/n LM120H-5.0, but it looks to be only rated to 0.5A instead of 1.5A per the LM120 datasheet at the below link.

http://www.ti.com/lit/ds/symlink/lm120.pdf

Can you help us with this?  Can you verify LM120K-5.0 is obsolete by providing its PDN?  Also, can you provide its replacement or cross?  

Thanks,
Dan Rapp

    Hey Dan,

    LM120K-5.0/883 is indeed obsolete. I've attached the PDN. 

    We don't have an exact P2P replacement so I'd recommend the UA79 series as the closest alternatives.

    Hi Aaron ,

    This  [defense components]  customer  (Minh Tran, who posted above)  is interested in purchasing the DIE part to the obsolete

    p/n  LM120K-5.0/883. This customer really needs a 5.0V regulator with a 1.5A rating and that has the large temperature range

    from -55°C to +150°C. Also, the customer is interested in purchasing the DIE to the two similar part numbers  LM120H-5.0  and

    UA7905CKCS;  so we would need ordering part numbers to those two DIES as well. 

    Can you provide the ordering part number for the DIE to the obsolete p/n  LM120K-5.0/883?  Also, can you provide the ordering

    part number to the DIES for the two part numbers  LM120H-5.0  and  UA7905CKCS?

    Thanks,

    Hello Dan,

    LM120KG-5 MD8 is the die sale part number.

    For the UA79, there may be a wafer sale possible. For the LM120H, there is neither a wafer sale or die sale possible.

    Let me know what else I can provide and I'm sorry for the delay.

    Hi Dan,

    I got offer 3 parts for Die sale.

    1. LM120KG-5 MD8  Die Sale.

    2.  UA79 may be Wafer sale.

    3.  LM120H-5.0 Die sale or Wafer sale

    I did not get answer which one is /883 compliant?  Could you please confirm with them?

    can we have a quote and lead time for LM120KG-5 MD8 and LM120H-5.0 in quantities of 100, 500 and 1000 or wafer quote that fine?

    Thanks for your help.

    Hi Minh,

    You can see Aaron's response above your comment:

    1.   LM120K-5.0/883  (DIE p/n  =  LM120KG-5 MD8)

    2.   LM120H-5.0  (no DIE or Wafer available)

    3.   UA7905CKCS  (only Wafer available)  

    As Mouser does not quote DIEs and Wafers, you will need to contact TI to find a distributor who does. It looks like only the first p/n with "/883" suffix is compliant as such. Lastly, as this query has become long and drawn out, it is best that you also contact TI with further queries related to such parts. 

     

    Thanks,
