Important information about replacing RoHS compliant FRUs
RoHS, the Restriction of Hazardous Substances in Electrical and Electronic
Equipment Directive (2002/95/EC) is a European Union legal requirement
affecting the global electronics industry. RoHS requirements must be
implemented on Lenovo products placed on the market and sold in the
European Union after June, 2006. Products on the market before June, 2006 are
not required to have RoHS compliant parts. If the parts are not compliant
originally, replacement parts can also be noncompliant, but in all cases, if the
parts are compliant, the replacement parts must also be compliant.
Note: RoHS and non-RoHS FRU part numbers with the same fit and function are
identified with unique FRU part numbers.
Lenovo plans to transition to RoHS compliance well before the implementation
date and expects its suppliers to be ready to support Lenovo’s requirements and
schedule in the EU. Products sold in 2005, will contain some RoHS compliant
FRUs. The following statement pertains to these products and any product Lenovo
produces containing RoHS compliant parts.
RoHS compliant ThinkCentre parts have unique FRU part numbers. Before or after
June, 2006, failed RoHS compliant parts must always be replaced using RoHS
compliant FRUs, so only the FRUs identified as compliant in the system HMM or
direct substitutions for those FRUs can be used.
Products marketed before June 2006 Products marketed after June 2006

Note: A direct substitution is a part with a different FRU part number that is
automatically shipped by the distribution center at the time of order.
