Replacement of component

jamesbooi · 24th May 2005, 06:42 AM

James from malaysia. I can't find a diode and transistor that i want, so if anyone can tell me which other model can be replace for below component, thank you.

1. replace for 1N457
2. replace for 1N3880
3. replace for 2N3792

James, here's some short data:

1N457: SI-Di, Uni, 75V, 0,075A, A: 0,2A
~=BA188..190, BAY45, BAY73, 1N484A,...
Uni = General purpose types

1N3880: SI-Di, Gl/S-L, 100V, 6A(Tc=100ø), <200ns
~=BYX 62/800
GI = Rectifier
S = Switching stages
L = Power stages

2N3792: SI-P, NF/S-L, 80V, 10A, 150W, >4MHz, B>50
~=BD546B, BD318, 2N6029..31, 2N6229..31,...
NF = AF applications

Hope this helps.

/Hugo

Thank you for your reply. I had view the datasheet and compare, and i found that replacement of 1N457 to 1N914A, and 1N3880 to MR751 is more suitable. You can go in to www.datasheetarchive.com to find the component i mention and compare, and give me a comment, maybe i found a wrong component? Anyway thanks alot for your reply.

James,
I'm sure that many more diodes can replace the 1N457 and the 1N914A is one of them.

As for the 1N3880, I would consider looking for the same case style, being D0-4, MR751 being 194-04. If this is not a issue, the MR751 is probably a good replacement.

And for europeans 1N914 = 1N4148

If you tell us where you will use thses parts I'm sure we will be able to find something. It's possible that some of the parts are very unsensistive when it comes to choice meaning it will work with just about anything.

Hmm.... actually i try to build a power supply, i use LM317K and those component that i couldn't find. I use the power supply for 13V, Imax= 3A supply, hmmm.... i do not have the schematic diagram with me now, but i will post online later.

Are u building a 12V battery charger??????

jamesbooi · 27th May 2005, 04:10 PM

Yes, i building a 12V (variable to 30V) power supply with 12V lead acid battery charger in separate circuit, and combine them up to build 1 complete circuit with battery charger. Still under construction, cause i can't find some component i need. Hmmm.... lately i will attach the schematic diagram on forum for comment.
