ECG/NTE/SK SEMI-CONDUCTORS

LOW EVERYDAY PRICES
OUR PRICES IN BOLD PRINT
The dealer net info comes from catalogs like Newark, Allied, Richardson, MCM , CEI etc.

These semi-conductors are actual ECG/NTE/SK or exact equivalents. They are listed by the ECG/NTE number. The 2nd column shows the actual brand & p/n and the 3rd column the SK (RCA & later Thomson) equivalent number. In cases where the GE, SK or Zenith has no ECG or NTE equivalent, they are listed at the end of the table by their GE, SK, Zenith or other major appropriate number.

Notes: Before Raytheon adopted the REN system, they used an RE numbering system that differed from the ECG/NTE system. Same with the old GE (GE, GEIC etc), Motorola (MRO & HEP series), Tung-Sol (TS), Sprague and Workman (WEP) replacement line series. Some WEP numbers are the same as HEP (Motorola) numbers. Thordarson-Meisner used the ECG system pre-fixed by TM and Zenith used a combination system with their own numbers and ECG style numbers. ELM used the ECG/NTE number system. They were from Elmira Electronics, a well-known supplier of Westinghouse tubes. The Westinghouse name was supposed to be tied to the ELM series, but it never happened, although the packages did use the W-house colors. Lindal (ER) used a different numbering system which was also used by several other smaller suppliers. Unfortunately, neither ECG or NTE (nor even SK) included the ER series in their xref books. I do have an xref to ECG supplied by Lindal. It's a very small list. Another supplier using the ECG/NTE numbers was Phyltron prefixing with LX. Another common prefix with the ECG number was TCG. This was actually the predecessor of NTE (Newtone Electronics). Sylvania protested that it was too close to their ECG. They won and Newtone changed to NTE for their prefix. In Feb of 2001 NTE bought ECG (another case of the upstart eventually gobbling the master) from Philips who had inherited it when they bought Sylvania. Since NTE swallowed ECG and Thomson allowed RCA/Thomson's SK series to fizzle, NTE reigns supreme in the semi-conductor aftermarket replacement world.

Unless otherwise noted, these are all in their original package.

To research your semi-conductor, go to this NTE cross reference. When you have found the replacement number, return to this page and find it in the left hand column. Simple as that!

Go here for Generic Semiconductors (mfgs part number) that are NOT exact equivalents of ECG or NTE numbers.

Check the Semi-conductor Accessories page for sockets, mounting kits, heat sinks and etc. There is also a link from the ECG/NTE number on this page to the appropriate socket etc. on that page.

SEARCH ENGINE HINT: When using your favorite search engine to find components or tubes, enter the part number (without ECG or NTE prefix), a space then "ECG" or "NTE" and followed by pax. (example: 102A ECG Pax). That will bring our pages up near the top of your list.
