Description: Tektronix TDS500x exact functional replacement for DS1286. (Same amount of memory, registers, etc.), no slower than 150ns. Also confirmed to work and fit ok in a Haas CNC VF1 VF2 VF SL Lathe Mill. www.practicalmachinist.com/forum/threads/replacing-battery-in-a-haas-control.206311 The 1st 3 pictures show the Tektronix installation while the last 2 pictures show the Haas CNC installation. Last picture is the Haas CNC showing the original DS1286 chip that can no longer maintain the date/time. There is no oscilloscope included with this auction. Only one chip plus socket is included. QTY 1 DS1286 replacement. If you must program this chip manually, try not to overwrite address 0x00 thru 0x0d, which is the RTC area. If you have option 05 (video trigger) this chip is too tall to fit that application, but I have another auction that will work for this case. Refer to ebay Item ID: 304107400658.The 3rd picture shows there is a small gap between the DS1286 and the DS1650Y....the replacement DS1286 does not overhang the DS1650Y. This chip will be tested in a Tektronix TDS524A. Benefits vs old DS1286: 1) Battery easily replaceable. 2) Installed Battery can be larger than the original 3V 120mAh, BR1632. (Installed battery is 1000mAh) 3) Battery voltage easily measurable. 4) Battery not installed until part is ordered. 5) No more worries about Counterfeit parts from shady sources. 6) This part is not obsolete with no replacement like the original. You can kludge/bodge your existing DS1286 provided only the battery has failed. It’s not too hard to look around and find videos/pictures of how to do it. Drill in exactly the right place...solder...glue, etc. Pretty messy if you ask me and the exact definition of a bodge. And if you’re lucky you won't break a pin off the DS1286 when you’re pulling it out for re-work, which would mean game over on that DS1286. These parts were created after I received a batch of 10 DS1486 from an eBay seller and later determined all 10 parts were bad. The parts even had a date code of 2015 when the seller’s picture clearly showed a 2009 date code. I attempted to return those parts but the seller refused to provide the return to China shipping label and I had to eat the cost of those parts and shipping. So now my rotten experience results in a good solution for those honest eBay buyers. And yes I know we are talking about DS1286 here, but after the DS1486 China debacle, I did not bother trying the experience again on a DS1286. I am not accepting large quantity orders on this part. It’s only available to those hobbyist who really need the parts. If you are buying these for a Tektronix processor board repair, you will have to carefully unsolder your DS1286, then solder in the socket I provide, then insert the replacement part in the socket. If you have never unsoldered or soldered parts before, I would NOT recommend trying this for the first time on your Tektronix processor board. No testing done on other instruments other than the TDS524A. Up to 5 days handing time on this item. That will give me enough time to build and test your parts before shipment. Typical handling time is between 1 and 2 days.
