I need assistance with two transistors and info if data sheets are available.
1. MJE3055 Data sheet and MJE3055T Data sheet to see if they are interchangeable.
2. MJE2955 Data sheet and MJE2955T Data sheet to see if they are interchangeable.
One other part a IC
1. L165 DATA sheet and L165H Data sheet to see if they are interchangeable.

I get datasheets from www.datasheetarchive.com . I can select a manufacturer.

A 2N3055 is in a steel case and has a max allowed internal temperature of 200 degrees C.
An MJE3055 is in a plastic case (T) and has a max allowed internal temperature of 150 degrees C.
Their max allowed currents are also different.

In most cases they are interchangable.

;D Tanks again I have the data althou  I can not find  a l165h part source yet.
Any ideas about thermistors and a Icl7107. the gage goes down with a 1k
thermistor and a 100ohm ntc thermistor and is supposed to go up instead.
