Transistor Replacement Help

[stk_1994]

Hey guys. Long story short, I need some help finding a suitable replacement for a BC200Y Transistor for a circuit board I'm working on. I'm not familiar enough with Transistors to choose a replacement on my own quite yet. If someone knows a thread that can help me or if they can just tell me a good alternative, that'd be great. Thanks in advance!

P.S. I also need to replace a LM431BCZ, but I already found a TL431CLP Transistor which has a lot of the same values. Just wanted to run it by you guys before placing the order.

Re: Transistor Replacement Help

BC200Y is NTE 159 which is a PNP Silicon, Lo-Noise Audio Amp, Switch. It comes in a
TO-92 Case, Max Collector Current (Amps):1, Collector to Base (Volts):80, Collector to Emitter (Volts):80, Emitter to Base (Volts):5, Forward Current Gain:180, Max Collector Power Dissipation (Watts):0.625, Typical Freq (MHz):200.
With the flat side down and pins at the bottom, the pins are Emitter Base Collector.
Yes the LM431BCZ can replace TL431CLP as they both are NTE 999 which is an Adjustable Precision Shunt Regulator and not a Transistor. With the flat side down and pins at the bottom, the pins are Cathode Anode Reference.
Hope this helps.
