General Information Relays produced after the specific date code that is indicated on each data sheet are lead-free now. Most of our signal and power relays are lead-free. Please refer to Lead-Free Status Info. (http://www.fujitsu.com/us/downloads/MICRO/fcai/relays/lead-free-letter.pdf) l Lead free solder paste currently used in relays is Sn-3.0Ag-0.5Cu. l All signal and most power relays also comply with RoHS. Please refer to individual data sheets. Relays that are RoHS compliant do not contain the 5 hazardous materials that are restricted by RoHS directive (lead, mercury, chromium IV, PBB, PBDE). l It has been verified that using lead-free relays in leaded assembly process will not cause any problems (compatible). l "LF" is marked on each outer and inner carton. (No marking on individual relays). l To avoid leaded relays (for lead-free sample, etc.) please consult with area sales office. l We will ship leaded relays as long as the leaded relay inventory exists. Note: Cadmium was exempted from RoHSon October 21, 2005. (Amendment to Directive 2002/95/EC) l DI SC ON TI 2. Recommended Lead Free Solder Profile l Recommended solder paste Sn-3.0Ag-0.5Cu.
