Please help me match a component (relay) - pics included

[beatbox]

Hi,
This is a very newbie question. Hope someone can help.
I have a Samson Studio Amp which has a problem with audio drop outs.
I've read that it's a known problem with the output relay. So I want
to replace the part.

There are pics of the relay and the relevant part of the amp schematic
here:
http://picasaweb.google.com/downlode/Relay?authkey=i9h4qlCCJXY

The spec for the part seems to be here:
http://hankukrelay.en.ecplaza.net/1.asp

It has six pins.

Can anyone suggest a part I can buy in the UK which matches the spec?
I saw a post in a forum where someone said they used the Finder 40.52,
here:
http://www.findernet.com/comuni/pdf/S40EN.pdf

But they had to snip off two of the pins. I notice it is rated at 8A,
while the original part seems to be 5A. Is that significant? If I was
to use that part, would I buy the 24VDC one?

Thanks for any help!
Mike

Hi, Mike. It looks like you're headed in the right direction for
finding a replacement for the Han Kuk relay (I don't think they've got
distributors -- they seem to be a Korean B2B manufacturer).

There aren't any datasheets available on the web for the Han Kuk
relay. Working with the picture and link you provided, the original
is a 24VDC coil relay with two "Form A" contacts. That means there
are two separate switches inside the relay. When the relay is
energized, both switches turn on. There are no extra contacts for the
switches so the common will make with another contact when the relay
is off, too. That would be a "Form C" contact.

Many times, the audio engineers will start development with a standard
product, and then try to wring savings out. If the board footprint of
your Han Kuk is a standard 5mm, it's very possible the engineers
decided to save money here. Two fewer PCB holes, and also a somewhat
less expensive relay if they only needed two normally open contacts.

Now your replacement *is* a two pole Form C, which means it's got
those two extra, unneded contacts. Cutting off the two extra pins
will not hurt the internals of the relay in any way. Apart from
making it useless for reuse, there's no problem there.

Now the relay contacts have a rating for how much current they can
switch on and off. The Han Kuk is apparently rated for 5 amps, and
the Finder is rated for 8. That means the Finder may have slightly
heavier, more durable contacts (silver alloy), which can switch a
slightly greater current. Either that, or the folks at Finder may
just be defining contact life a little differently -- there's no
absolute standard. Either way, there should be no problem with using
the Finder as a replacement once you cut off the extra pins -- that
is, assuming the PCB layout of the Han Kuk is the same.

Good luck
Chris

Thanks a lot Chris, I'll give it a go. I hope this one does have more
durable contacts that Han Kuk!
Best wishes,

Hello, When doing relay replacement, you can consider HONGFA's relay.
