In the DIN, EN and ISO datasheets (as well as other country standards) certain parts are often labelled "replaced".
These
sizes can be marked in the configuration file $CADENAS_DATA/datasetup/replace_std.cfg
(set for CADENAS standard parts and may be adjusted by customer
administratively).
This feature exists since version 8.1. It is continued in V9. It goes hand in hand with Avoid parts and Expiration date.
In the PARTdataManager in the directory tree, the affected parts are marked with a symbol.
