Collection: NTE & ECG Cross-Reference Semiconductors

NTE and ECG cross-reference replacement semiconductors — aftermarket house-numbered devices used to replace hard-to-find original parts in legacy electronics. ECG-numbered devices are long discontinued, and NTE Electronics ceased operations in 2024, so remaining stock of both lines is new old stock and surplus. Cross-reference information does not guarantee suitability for every circuit: always confirm the original device's ratings, package and pinout before substituting.
