Pro Electron
Pro Electron/EECA is the European type designation and registration system for active components (such as semiconductors, liquid crystal displays, sensor devices, electronic tubes and cathode ray tubes).
Pro Electron was set up in 1966 in Brussels, Belgium. In 1983 it was merged with the European Electronic Component Manufacturers Association (EECA) and since then operates as an agency of the EECA.
The goal of Pro Electron is to allow unambiguous identification of electronic parts, even when made by several different manufacturers. To this end, manufacturers register new devices with the agency and receive new type designators for them.
Designation system
Examples of Pro Electron type designators are:
AD162 – Germanium power transistor for audio frequency use
BY133 – Silicon rectifier
BZY88C5V1 – Silicon 5.1 volt Zener diode
CQY97 – light emitting diode
ECC83 – 6.3 volt heater noval dual triode
A63EAA00XX01 – Color TV picture tube
SAA1300 – Digital integrated circuit
