DESCRIPTION
ECG ECG199 silicon NPN bipolar transistor designed for low-noise preamplifier and small-signal industrial amplifier applications. This discontinued three-lead transistor features high current gain, low collector saturation voltage, and low-noise performance in a compact TO-92 through-hole package.
The ECG199 cross-references to the NTE199 replacement transistor. Compatibility should be confirmed by comparing the electrical ratings, lead arrangement, circuit requirements, and original equipment documentation before installation.

Quantity of One
This component is New Old Stock from long-term inventory. It has not been installed or placed into service. No functional testing has been performed. Cosmetic storage wear, surface marks, oxidation, discoloration, or slight lead irregularities may be present from age and handling. Please review all photographs for the exact condition and markings of the component being offered.
DISCLAIMER
This item is New Old Stock from long-term inventory and has not been functionally tested. Due to the age of this discontinued electronic component, compatibility and final testing are the buyer’s responsibility. Cross-reference information does not guarantee suitability for every circuit. Verify voltage, current, gain, power dissipation, package, pin configuration, and application requirements before purchasing or installing. Ships fast with tracking. 30-day returns accepted; buyer pays return shipping.

COMPATIBILITY & CROSS-REFERENCE
ECG and NTE are aftermarket cross-reference replacement house numbers, and the ECG199 corresponds directly to the NTE199. NTE's published datasheet specifies the NTE199 as a silicon NPN transistor in a TO-92 package designed for low-noise preamplifier and small-signal industrial amplifier applications, rated 50V collector-emitter, 70V collector-base, 5V emitter-base and 100mA collector current, with low collector saturation voltage and tight beta control — matching the ratings of this device. ECG-numbered devices are long discontinued and NTE Electronics ceased operations in 2024, so remaining stock of both lines is new old stock. Confirm the original device's ratings and the emitter-collector-base lead arrangement before substituting.
Q&A
Q: What is the ECG199? A: A silicon NPN low-noise, high-gain transistor in a TO-92 package, rated 50V collector-emitter and 70V collector-base with 100mA maximum collector current.
Q: What is the NTE equivalent? A: The NTE199 — NTE's published ratings match this device.
Q: Where is this transistor typically used? A: Low-noise preamplifier and small-signal amplifier stages in audio, radio and instrumentation service work.
