Now that you have finally given us more information I would be inclined to
suggest that you replace the bridge with a "like and kind" exact OEM part or
a possibly upgraded voltage and current version.
Since this is in a commercially designed overhead projector and used in a
school, you would be best advised NOT to CHANGE the original design or use
anything other than a "factory" part.
Bridges of this nature and rating are readily available so stop wasting time
posting to the newsgroup and get online and order the proper part.... get
the proper and safe part that was originally installed.

The one word that comes to my mind is "liability".

I have to replace a KBPC602 bridge rectifier. It is rated 200VRMS at
6.0 A. It is wired into the circuit using only the + and - terminals.
The AC connections are not used. If I were to build a bridge out of
four 6.0 amp 100V diodes, would I be able to directly replace this
device? Does the circuit basically require a 12.0A 200V device?
Conversely if I were to place four 3.0 amp 200V diodes in parallel
would that arrangement work also? Thanks. Lenny Stein, Barlen

I talked to a tech at Elmo this morning and asked about the use of the
bridge as opposed to using a large single diode. He said that the
engineers found that the DC when looked at with a scope from the
bridge was cleaner than the output of just a single diode. Does that
sound possible? As far as wasting anyones time, if I was I appoligize.
I thought we were having an interesting discussion. Lenny

Lenny:
We were and are having an interesting discussion and thread and no,
you are NOT wasting anyone's time.
Instead of trying to find ways to jury rig a substitute for a common
and readily available bridge rectifier you should have just procured
one and installed it and be done with it.... saying that, perhaps the
only person's time "wasted" was your own.
Until your later posting that revealed it was for a commercially
manufactured overhead projector being used in a school environment you
had everyone guessing about how the bridge was being used in the
circuit, in fact, you never revealed the circuit in any kind of detail
as it related to equipment, configuration, voltage, amps, etc... even
after several reply posts asked you for details about it.
As you know, none of us can read minds and no one has a working
crystal ball on the newsgroup so the more information an OP can give,
the better and more straight forward will be the answers.
The best answer for fixing the overhead projector is to replace the
bridge with an OEM part..... obviously other parts and configurations
will work, BUT if something goes wrong and the projector malfunctions
and causes smoke and fire damage... particuarly in a school
environment.... your LIABILITY will be much more exposed if you
DIDN'T use replacement parts that were used in the original
manufacture. Enough said.
Lenny, please feel free to start up more "interesting"
conversations... it sure beats the spammers and the trolls and their
filthy subject matter. Electronics discussions are much more
enjoyable than that crap.
