Yes. You can get it for pretty cheap.
Just dont expect DIV quality on your image. It will downscale to VGA quality due to use of the adaptor. But it shouldn't be an issue.
Edited:
Just use this one instead.

DVI-D does not carry an analog signal, required for VGA. Rather than a simple adapter, you need an active converter to translate the digital signal for use by VGA.
You need something like this, rather than the cheaper adapters used by DVI-I (carries both digital and analog signals):

Pretty sure if the adapter is compatible with DIV-D to VGA as the ones we linked above. It should work as they have chips built in to do the conversion.
Even just to troubleshoot. If you want to save money, purchase the adapter we suggest above since it is only a few dollars. If it doesn't work. Then spend more and get the active adapter.

Then why sell an adapter that goes from DIV-D to VGA if it doesn't work? Sorry that doesn't make any sense.

The specs for that adapter specifically state that it is for a DVI-I port and will NOT work on a DVI-D port:

You are looking at the wrong link. Click on my original post link.
I saw it was DVI-I and changed it to DVI-D. Must have been just as you were quoting the original post.
The second post on google search for DVI-D to VGA stating that on the description, but takes you to the wrong adapter. Hence the link update.

They would have also been using it on a DVI-I port instead.
The thing works. They dont make the product if it doesn't function. There are many other adaptors out there, that was just linked as an example.

These cheap passive DVI-D to VGA adapters are only for specific signal convertering devices(not video cards), many of these adapters even state that in the specs, others mislead buyers to make a quick sale.
They are abundant because they are dirty cheap to make and idiots keep buying them because they don't know the difference. And return shipping usually costs more than the adapter so people don't return them.
I removed the BA so future readers who don't read the whole thread get misled and buy a worthless adapter.

I've personally used that one I linked in the past and it worked. Although it was for an older card and its older tech a few years ago. So who knows nowadays.
All I know is in the field I have replaced so many active adaptors I can't even count. They are pretty weak and susceptible to interference and surge issues. They tend to be the first thing on a PC go bad.
If you want to be 100% sure the device is compatible with your system. Then sure go with the active box type adaptor. If you want to spend a whole 4 dollars and test the one linked earlier. Then do that, if it doesn't work, oh no, you lost 4 dollars, if it does work, you just saved 20 dollars...
So its up to the OP.
I'm just speaking from experience. Active adaptors in general are pretty cheaply made and tend to fail pretty often. But they can do the job. Just keep that in mind as one of the first troubleshooting steps you do when you run into display issues. It's most likely the active adapter.

You obviously had a dvi-i port and were using a passive dvi-i to vga adapter(many cards use to come with these adapters). On older cards most dvi ports were dvi-i.
Vga is analog only.
Dvi-i carries an analog and digital signal so passive adapters work just fine.
Dvi-d is digital only.
Going from digital to analog(and vice versa) requires a converter also known as a passive adapter. Not everyone can afford to sent a few bucks on fire. Like every other electronic device if you buy the cheap you are likely going to have quality issues.

Yes. I know all that.
I'm just stating it has worked. and no I didn't have DIV-I. I know the pin layouts.
A straight connection would not work of course. But a lot of these adapters are not a straight conversion. Its not like plugging in two different ends of a cable together. Some of these adapters typically have components in them to do the conversions. Aka a chip.
It is obvious the active adapter with the box format has the chip. It is not obvious if the one I linked has an embedded chip or not.
Considering it is cheap as you stated. It is very possible it may not have it and may not work.
Wont know until you try.
All I can state is from what I have tried. I've used an adapter in that form factor that wasn't connected to a box adapter for DVI-D and it worked.
So again my above comment still stands. If he can't afford the 4 dollars or wants to ensure he gets one that will work the fastest. Then go for the active adapter.

An adapter with the conversion chip is considered an active adapter. There are 2 types of active dvi-d to vga adapters, ones that are powered from the port and ones that are external powered(usually powered via a usb cable). I have had the best luck with the usb powered adapters.
Adapters without the chip are passive/passthrough adapters are next to worthless and will not work for the OP.
The main issue I have is the adapter in your first post is obviously a cheap passive adapter, hence the flak you are receiving. It's not even sold or shipped by Newegg just a Chinese seller from the marketplace trying to ripoff the ignorant.

Fair enough. Then dont get it.
You get cheap expect cheap results.
But like I said, don't be surprised if the active adapter fails sooner then later. That is still cheapish and open to issues as I listed above.

Atleast the active adapter will work unlike the worthless passive adapter you posted that won't work at all.

So then just clear up the topic by removing the comments. No reason to confuse the OP.
