A Pb-Free version of Semtech’s base part number may be available under a new part number.
Semtech’s Pb-free parts are designated with a unique suffix. Devices with part number suffix ending in “T” or "LF" are Pb-free. Using Semtech’s base part number nomenclature you may locate the Pb-Free part number and information on the Pb-Free version of the device. To learn more, contact your Semtech sales rep.
Note: Do to size limitations of many of Semtech product packaging there is no Pb-free designator marked on the part itself [top]
When placing orders for Pb-Free devices use the Part Number listed in the Semtech Lead-Free Part Number column. [top]
Pb-Free: Semtech Corporation defines "Pb-Free" to mean semiconductor products meet the requirement that lead content not exceed 0.1% by weight in homogeneous materials unless exempt. [top]

Product identified and qualified for automotive application(s). Product qualified and tested to AEC Q100. Temperature grade is noted below:
· AEC-Q100 has following Automotive Grades;
Grade 0 (or A): -40°C to +150°C ambient operating temperature range
Grade 1 (or Q): -40°C to +125°C ambient operating temperature range
Grade 2 (or T): -40°C to +105°C ambient operating temperature range
Grade 3 (or I): -40°C to +85°C ambient operating temperature range
Grade 4 (or C): -40°C to +70°C ambient operating temperature range
Typically Commercial product would align with Grade 3 and Industrial product would align with Grade 2 and Grade 0 and 1 align with automotive.
More specifically with the automotive grades Grade 0 is usually used under the hood (due to harsher ambient conditions) whereas Grade 1 is used elsewhere in the vehicle (in the cab).
Refer to the product data sheet for aumotive application, AEC qualification and grade information. Refer to the product data sheet for automotive application, AEC qualification and grade information. AEC Q101: Applies only to automotive Grade 1 (or Q): -40°C to +125°C ambient operating temperature range grade 1 product. Refer to released product data sheet. [top]

Halogen Free or Low: According to the industry organizations, the term low-halogen has not been clearly defined in the industry and is not a regulatory requirement in any worldwide legislation, although it is being used in the industry.
To eliminate any confusion in terms of the definition of low-halogen, IEC 61249-2-21 and JS709 standards provides a concise definition to identify passive and solid-state devices containing low concentrations of bromine and chlorine, from brominated and chlorinated flame retardants (BFRs, CFRs) and polyvinyl chloride (PVC).
Although the halogen group contains fluorine, chlorine, bromine, iodine, and astatine, this document uses the term “low-halogen” to refer to only bromine and chlorine. [top]
Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. Proposition 65 also prohibits California businesses from knowingly discharging significant amounts of listed chemicals into sources of drinking water.
