Recommended practice for the representation of component catalog data in STEP AP210 (ISO-10303:210)



Kevin G. Brady


The purpose of this document is to recommend a practice for the representation of electronic component catalog data in STEP AP210 (ISO-10303:210). Catalog data encompasses a wide variety of performance characteristics and specifications, rating limitations, operating recommendations, and ratings provided by component suppliers through product data sheets and catalogs. In current practice, the majority of this information is communicated between component suppliers and their customers through human readable .pdf documents containing a combination of tables, data plots, and technical drawings encompassing the necessary functional, physical, and performance characteristics of the device. The scope of this recommended practice is limited to the representation of component data that may be represented as individual characteristics or tables of characteristic values, and excludes detailed product model views such as the schematic symbol, footprint, and package, or mechanical outline. The majority of the data requires representing physical quantities with specified units.
