Part number/source for the RTC Battery holder

So - even after all the warnings, I managed to snap the plastic on my 11th Gen motherboard’s RTC battery holder. Anybody have an idea for a part number of what I’d use to replace it?

I realize that referb 11th gen boards are <$200, but throwing this one out over a $1 surface part without at least trying would rub me the wrong way.

Browsing the website got me to the ‘connectors’ repository and the Interface schematics GitHub page, but I don’t see a BOM anywhere in there - If anybody’s got one, or can at least get me a part number, it’d save me hours of squinting at Mouser’s website.

I’ve currently got a folded-up piece of post-it holding the battery in place, but I doubt that’s very durable or particularly good long-term.

Contact support and they may be able to send you a replacement battery holder.

No response from support as far as I know, so I’m doing the bomb-squad thing and making notes as I stumble to my own answer.
This image of an 11th gen MB shows ‘ML 1220’ markings - and Maxell’s ML1220 data sheet shows it’s 12.5mmx2mm in size., which gives us a starting point.

Keystone Electronics 1056 doesn’t look anything like it, but fits the cell.
Renata SMTU1220-LF looks like a closer match, but it’s apparently out of stock everywhere?

…but if we drop down to 12mm in rated size, we get
Keystone Electronics 1072-TR… which is a perfect visual match.

I feel like an idiot for kicking myself about breaking the socket now, when it’s under size for the flipping battery!

Did support respond to your request at all or do you mean that they refused to send you the RTC cradle?

No response as far as I can tell. But I’ve got an answer - I’m probably going to order all of them (<$10?) and reinstall the 1072-TR only if none of the ones actually meant to take a ML1220 will fit under the keyboard.

Did you create a support ticket recently and when creating it, did you receive an autoresponse?

I created one back when you previously suggested, and upon reviewing my email, I realize I did not receive an autoresponse.

Are you using a major email provider to contact support (e.g. Gmail, Outlook)? In the past, people have had issues contacting support due to the use of custom/self-hosted email services. Also ensure that @frame.work and @framework.kustomerapp.com are whitelisted.

I’ve interacted with tech support in the past fine, but it’s no longer required with this issue.

For anybody that comes after me:

I used the Keystone Electronics 1072-TR(Above) - The other connectors were physically too large for the space.

Cut the damaged socket’s plastic out with snips, desolder and clean up: I used a suction tool, use whatever you’re quickest with. Plenty of other stuff on the board to knock loose if you overheat.

Very light coating of solder on the new part contacts - You want the new part’s pins to sit in the anchor/alignment holes cold. I used flux.

The top contact (above) is under the part - set the iron to about 400 and heat the connector from the inside of the holder - The plastic will take the heat, but probably not forever - get out as soon as you’ve got a good joint.

The bottom one is straightforward because it’s external and exposed at the edge of the case.

Good luck, have fun, and use a microscope and a pick to ease the bottom edges of the holder onto your CMOS battery replacement.
