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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eQ\u0026amp;A\u003c\/strong\u003e\u003cbr\u003eQ: What is included in this lot?
