TMS570LS3137: Actual Part Number is TMS5703137CGWTQEP

Hi AJ,

There are three type of lead finishes for TMS570Lx parts.

1. For TMS570Lx EP parts: it is SnPb, which is not lead-free

2. For TMS570Lx  non-EP BGA parts: it is Tin-Silver-Copper (SnAgCu) which is lead-free (Pb-Free)

3. For TMS570Lx  non-EP PGE package: It is Nickel-Palladium-Gold (NiPdAu) which is lead-free too

Today TI's lead-free products use Ni/Pd/Au or annealed matte tin (Sn) for leadframe type packages and Tin/Silver/Copper (Sn/Ag/Cu) for ball grid array (BGA) types of products. 

Hi QJ,

I'm not sure you understood my question, my apologies about the miscommunication. Let me clarify this a bit below. 

Shouldn't the TI part that is calling out a mil-spec part be the same as what the mil-spec calls out? Clearly, there is a mismatch here that doesn't make a lot of sense. To my understanding, the TI part is suppose to be the same as V62/13629-01XE, like it's clearly called out on the TI datasheet. See image below, this is a snip-it taken from the TI product page. 

Your answer above does no address the question/concern that the "E" suffix is supposed to stand for Gold Flash Palladium, according to the mil-spec, but the TI datasheet calls this out as SNPB. Please take another look at my image above in my initial question. This doesn't match up and we would like some clarity on why this is. 

Thanks,

Hi AJ,

I am sorry I don't know the part numbering conventions for DLA parts. The snapshot you posted is pretty blurred, I am still not clear what do -01XE or -02XE mean in the DLA part numbers. 

The note #6 of packaging info in device datasheet says the devices may have multiple finish options. Don't know how those options are reflected in the part #.

(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width.

You may check with sales. Can you send me a private message? I will forward your question to our marketing team (and cc to you).

Hi QJ,

My apologies for the blurred picture. Please see below. The DLA calls out the "E" suffix specifically being Gold Flash Palladium. My concern is that TI calls out this same part number, claims that it is the same as the mil-spec part on the website, but it has the "E" suffix and the datasheet calls out SNPB. Clearly this is a mismatch.

Thank you,

Hi AJ,

There seems to be a mismatch. I am following up on this internally to get the correct information.

Any updates on this? My team is still looking for an answer.

Thanks,
