for new requests it is suggested to open a new thread so that you get a response 

check the following link if this is helpful

-----------------------------------------------------------------------------------------------------------------

With reference to above suggestion, i have raised the following query:

https://china.xilinx.com/support/documentation/package_specs/pk156_fg680.pdf

I could find the material info for FG680 part, The query i have on this part is related to the RoHS compliance :

I do understand this part is not RoHS, when i go through the Lead content it is shown as 0.513 g ?

I would like to understand bit more on this device, like is this part RoHS compliant but not RoHS compatible ??

What i meant is : RoHS compliant( containing material within the permitted levels) & may not be RoHS compatible (cannot withstand per RoHS soldering profile)

Hi @vinaykattela,

RoHS compliant means that the component does not contain six hazardous substances: lead, mercury, cadmium, hexavalent chromium, PBB, & PBDE. In selecting alternate materials to plate the leads, component manufacturers will look at characteristics such as solderability and resistance to whiskers. It does not mean that these parts are compatible with the manufacturing process.

RoHS compatible means that the component can handle the higher solder temperatures used in RoHS board assembly. RoHS manufacturing requires at least 30º C higher soldering temperatures than Tin-Lead to ensure reliable connections between the board and components. Also, since lead-free solders have poorer wettability, the components and PCB are held at this higher temperature for much longer time than tin-lead solders. The issue is that some RoHS compliant components cannot handle these elevated temperatures.

From the RoHS compliance point of view : i understand there is a possibility of hazardous substance but within the permissible limit per the directive? 

My question was not on the definition of compliance & compatibility.

My question was whether the part XCV1000E-6FG680C - RoHS compliant but not Compatible ??

I do have one more question :

Can soldering profile be same for a specific part#, For example XCV1000E-6FG680C Vs XCV1000E-6FG680I : Can these both parts use same soldering profile ??
