ECG

ECG cross-reference replacement semiconductors — house-numbered transistors and related devices used to replace original parts in legacy consumer, audio and industrial electronics. ECG-numbered devices are long discontinued, so remaining supply is new old stock and surplus. Many ECG numbers correspond directly to NTE equivalents. Always confirm the original device's ratings, package and pinout before substituting. Fast shipping from American Industrial Parts Group.
