TPS61087-Q1: DRC0010R and DRC0010J

Part Number: TPS61087-Q1 Hi Team, What is the difference between DRC0010R and DRC0010J? If customer need to draw the package, which one should they draw, R or J? There are two types of thermal resistance, but there is indeed only one type of package VSON. Is there any difference between the two types of thermal resistance in the shape of chip?

Amelie, No big difference, either package is OK.

Hi Helen, Thanks for your reply. Which package do you recommend? It seems WDR has better thermal performance. So the 2nd one TPS61087QWDRCRQ1 is the better choice?

Amelie, I replied you by email. it depend on the customer. if they want to check the soldering by eye, then they can use WDRC, this is a new package generated last year. while the other is old one. WDRC is more expensive. Some high-level automotive customer likes it. While DRC is cheap and most customer choose this one.
