ROHS compatible product

What do you exactly mean? if the component is compliant with the ROHS rules then it can be used until the ROHS rules become more strict.

But as per SGS ROhs certification program the valid period is 5 years.

As well most of the semiconductor manufacturer Gives

Lead_free converted date for their product(ex.Philips(NXP)).

So wheather I have to check from whom they have taken the cetification for

checking validity? or shall I consider that product as Pb free product.

Or Do I need to ask them current declaration for ROhs compatibility?

I want clear explanation on it as I am making report for Rohs for the products in our company.

Actually When yu get certification from say SGS for ROHS compliant of your product then

they says that it is valid for 5 years . That mens yu need to do certification again.Suppose I am checking for electronics component in my product ,Then Some companies like Philips(NXP) or Onsemi gives the date saying that since what date that product is ROHS compliant.

Now if that date is 5 years before Then is it necessary to ask them that what is current situation?
Because right now I am collecting certificates for each component in my product.

Pls help me.

So if you buy a product from a ROHS compliant company and it is ROHS, then the product that you bought will still be ROHS complient after the supplier License expires. If you buy products after the 5 year period and the company has not re-newed it's license then those products are not ROHS Complient anymore

maybe this can help;
