J James Lundmark New Member Jul 27, 2017 #1 Trying to id a part on a controller board for an irrigation system. The part is cylindrical, silver, no markings, 5.8 mm x 1.7 mm. Might be a crystal or oscillator. Board has marking Y2 on it. Any ideas, cannot find a diagram. Thanks, photo attached Attachments 20170725_132451.jpg 781.8 KB · Views: 262

P Pommie Well-Known Member Most Helpful Member Jul 27, 2017 #2 Try adding a photo of where it came from. The board might give us a better clue as to what it is. Mike.

Nigel Goodwin Super Moderator Most Helpful Member Jul 28, 2017 #3 It looks most like a crystal, probably a 32KHz clock crystal.
J James Lundmark New Member Jul 28, 2017 #4 Tried to add Picture of board, located at Y2, message file too large, how do i attach, thanks

You probably have a very large picture. Try editing (crop) the file to make it smaller. Most editors also have a way to reduce the file size.

DerStrom8 Super Moderator Jul 28, 2017 #8 'Y' is often used as a PCB designator for a crystal, so I am agreeing with Nigel on this one.

DerStrom8 Super Moderator Jul 28, 2017 #10 What's on the other side of the board? Do you see an IC connected directly to the pins of Y2?
J James Lundmark New Member Jul 28, 2017 #11 This is backside of board, terminals circled in red Attachments 20170728_223333.jpg 1,022.5 KB · Views: 242
K KeepItSimpleStupid Well-Known Member Most Helpful Member Jul 28, 2017 #12 Yep, crystal. the next step is what are all of the numbers on the big chip? One corner of the chip should be "different" than the other 3. That's pin 1. Start counting CCW and what pins are Y1 connected to?

To clarify, one of the corners may be flattened rather than coming to a point, or perhaps there is a dot on the plastic. That is the pin 1 designator.

J James Lundmark New Member Jul 30, 2017 #14 Not sure which corner is different. Photo of chip attached. Cannot locate Y1. Advise, thanks Attachments 20170730_142349.jpg 1.8 MB · Views: 243
Nigel Goodwin Super Moderator Most Helpful Member Jul 30, 2017 #15 I don't really see what you're asking any more?, your broken part is a 32KHz clock crystal.

J James Lundmark New Member Jul 30, 2017 #17 Sorry, i guess i missed something. My board is for an irrigation control. I didnt make the conne tion witb a clock crystal. Thanks

J James Lundmark New Member Jul 30, 2017 #18 I see several different 32khz crystals. Will any work or should i be looking at a specific series or other parameter. Thanks

They all seem pretty well the same, I usually get mine out of old equipment A good source is old VCR remote controls, which have an LCD display on them - it's easier to find them inside the remote, rather than inside the VCR.
