1. What is the deadline for RoHS (lead-free) Compliance? EU: compliance has been required as of 1 July 2006. USA: Federal deadline not set as yet; California, Massachusetts, other States are in process. California required certain products to comply since 1 January 2007. Japanese firms usually require compliance. For China, regulations are pending. 2. Which regulatory standards do Scientific Conversion's parts comply with? RoHS, Directive on restriction of use of certain hazardous substances in electronic equipment. http://europa.eu.int/eur-lex/pri/en/oj/dat/2003/l_037/l_03720030213en00190023.pdf WEEE, Directive on waste electrical and electronic equipment. http://europa.eu.int/eur-lex/pri/en/oj/dat/2003/l_037/l_03720030213en00240038.pdf  Japanese Industry Chemical Regulation: JEITA, http://www.jeita.or.jp US standards are still being determined. Reflow Temperature Profile as per J-STD-020B, (large package) procedure for Pb-free soldering. Lead Free Finish Category: JEDEC e2 - Sn alloy. EU REACH Ver 4 June 2011 Our parts DO NOT contain substances of very high concern (SVHC), see EC 1907/2006 J-STD-020B Moisture/Reflow Sensitivity Classification (MSL) = level 1, not moisture sensitive. 3. When are your RoHS compliant transformers available? All our transformers are now only available RoHS compliant, LF suffix. Regular (non-compliant) types are no longer made. 4. How do they differ from the standard versions? Lead free solder used is industry standard SAC type, instead of tin/lead. Recommended peak reflow temperature is increased to 260C max, 10 sec. Electrical characteristics and mechanical footprint are identical. SC part number has LF suffix added;  i.e. old SC937-02 becomes SC937-02LF. IC tube Packages will be marked with the LF part number and have green end caps. 5. Are they backwards compatible i.e. can the LF version be used with tin/lead solder?  Yes, they are totally "form, fit and function" and pinout backwards compatible! 6. What about compliance documentation, ISO 9002 certification, Quality Supplier Survey, chemical analysis, or complete our spreadsheet? We provide a standard certificate of compliance (C of C) upon request. See the Industry Standard IPC175-2 forms at www.ipc.org. We can fill out your firm's special compliance and Quality Supplier Survey forms ONLY for orders exceeding 1,000 pc/year.
