OPA340: OPN with NiPdAu finish

Alen Barisic
Intellectual 1300 points
Part Number: OPA340
Other Parts Discussed in Thread: INA193

Hi Team,

we are using the OPA340NA/250  in an existing design. According to the attached PCN we should add the “G4” suffix in order to ensure the NiPdAu finish (it is very important for us to get this part in “NiPdAu” finish and not it “Matte Tin”).

Is this PCN still in effect/valid? According to ti.com both OPA340NA/250 & OPA340NA/250G4 have NiPdAu finish. As the G4 variant is not listed at this time, can we be sure that the OPA340NA/250 will have NiPdAu finish?

Thanks,

Alen

    At the moment, there are two manufacturing sites for the OPA340NA/250, and both use NiPdAu finish. See ti.com/quality-reliability-packaging-download/report?opn=OPA340NA/250.

    Below is the inventory in TI E-store, where all OPA340 packages' lead frame finish is plating with NiPdAu coatings.  

    Clemens is correct, all current lead frame finish are with NiPdAu finish in OPA340NA products.

    Historically, G4 suffix indicates that devices were Pb-free, eco-friendly molding compounds with NiPdAu coatings in lead frames. I think that the posted PCN (INA193) may be sent a while ago. For instance, I do not see any Matte Sn finish in INA193AIDBVR/INA193AIDBVT products in the inventory currently. The standard lead frame finish currently are NiPdAu or NiPdAuAg coatings. 

    OPA340NA/250 lead frame finish and compositions are summarized below. 

     

    If you have additional questions, please let us know. 

    Best,

    Hi Raymond,

    thanks for clarifying.

    Our concern was about the PCN 20210915000.1, which mentioned OPA340NA/250.

    For example SN74AHC1G86DBVR was mentioned in this PCN and its lead plating now seems to be Sn|NiPdAu according to TI website.

    Which means that the PCN has been applied for this part.

    So, regarding the part number: OPA340NA/250, should we assume that the PCN 20210915000.1 was only about an additional assembly site which produces this part with NiPdAu finish, as well ?

    Thanks,

    Alen

    You get PCNs only for new/changed manufacturing sites, but not when an old one gets dropped.

    When you buy OPA340NA/250 (or 3K) now, you can be sure to get NiPdAu.

    Hi Allen,

    Clemens is correct. There are some previous inventory that may bear older lead frame plating configuration, but the latest and most of the lead frame plating design is adapting the NiPdAu or NiPdAuAg coating stacks. If the specific lead frame plating is required, please ask the questions and check with material content information over TI e-store website and/or engineers.
