    Wondering if the Sanyo STK-3062 can be replaced with the Sanyo STK-3062 III. any help will be appreciated.:)

    Hi Rickster
    welcome :)

    did you have a look at any data sheets ?
    any signif. differences are likely to be seen :)

    thanks for the reply

    Ive been unable to find data sheets on these devices that tell me more than applied voltages. I figured someone would know of the top of their heads to save me time research it futher. Thanks again.

    If you search here for 'STK3062' and 'STK-3062' you'll get the 2 variants. The one with a '-' is the old one.

    They look more or less equal, the only difference is a couple of capacitors drawn in the old one, maybe parasitic.

    TOK ;)

    Have you considered writing Sanyo and inquiring about any migration notes for the revisions?

    Yes, I emailed Sanyo twice a week ago and still no reply from them

    Usually a suffix is an improvement. For example a 2N2369A is an improvement of a 2n2369 (.20V vs .25V saturation voltage). And usually any 2N2369 can be substituted with a 2N2369A but less often the other way around. Your chips STK-3062 and STK-3062 III are maximum supply voltages off 55 volts vs 59 volts.

    Strictly correct. It is best to read "less often" with its exact meaning rather than to assume much less often, or rarely.

    It is only an issue where the change in specification is actually important to the operation of the circuit. Given the way people design circuits, it's more likely that the designer was familiar with part XYZ and just used the newer XYZA than he went looking and found that XYZ would not work and XYZA would (but that is what you seek to determine).

    What it does do is get you focussed on the differences and you can determine if they are significant in this application.

    For more sophisticated devices (like hybrid modules) the change in revision may require fewer (or more) bypass capacitors, or bias resistor changes, or extra functions on previously unused pins, etc. so looking at the datasheets for both parts and playing "spot the difference" is a good idea if you can do it.

    Then there is the pragmatic approach. If you don't have the datasheets, the part is inexpensive, and the consequences of it failing are not highly significant, just replace it and see what happens (and that applies either way XYZ with XYZA or XYZA with XYZ).

    I read that the 3082 is supposed to be a good sub. Check MCM Electronics.
