Hello,

weirdly there is no ROHS indication (E3,E4 etc.) on the top mark of TPS53515RVE,as you can find in the attachment,we bought a lot of this part and all have E3 on the top mark.how to explain this?thx

The pictured device was assembled at a TI assembly site "I" and is NiPdAu and does not use E3 in symbolization.

If the device is assembled by our subcon partner there is a J or P after the 81 number (YMS year month site) and there would be E3 on package symbolization.

The RoHS information is here https://www.ti.com/lit/ds/symlink/tps53515.pdf#page=32

hello David,

thx for your prompt reply,but I found there is e4 printed on the label, shouldn't the device be printed with e4 accordingly? Do you indicate that all devices assembled at site "I" will not be printed with any ROHS symbolization?thx
