3.2.2. Naming

The following conventions apply to Package names:

• We generally follow IPC-7351C when naming packages (e.g. “SOT23-5P95_280X145L60” instead of “SOT23-5”). Alternative names (like “SOT23-5”) should be added to the comma-separated keywords list and maybe to the description.

• For packages not covered by IPC-7351C, use following naming conventions:

  • Language must be American English (en_US), if applicable (many Packages have language-neutral names anyway).

  • Size information must use metric units, not imperial units.

  • For packages which are available with different pin counts, append the pin count with a hyphen as separator and omit leading zeros (e.g. “DIP-8” instead of “DIP08”).

• For packages which are well known by their size in imperial units (e.g. “0805” which is “2012” in metric), it’s recommended to write the well known name in parentheses. For example, a chip resistor could be named “RESC2012X70 (0805)”.

• The name of manufacturer-specific packages should start with the manufacturers name (e.g. “Molex 53261-06”). Note: Libraries do not act as namespaces for Package names, so you should start the Package name with the manufacturers name even if the Package is located in a manufacturer-specific library.
