Not really.
Both ХСЧКВ-19&34 are NIZH(if put into single layer). Duplet is tandem installation into 2+ layers.
Best way to say would be like that.
Duplet
Spoiler
Wasnt able to find similar type picture for nizh, so it would be bulat’s UFP(you still can see that it’s into single layer)

You still can put both ХСЧКВ19 and ХСЧКВ34 into K-1 case, but it will act like shitty Russian ERA.
Theyre both have their dedicated boxes, to be not useless, have armor(armor for ERA, right) from MG and other stuff. ХСЧКВ has quite sensetive explosive inside, so it needs protection.
Also theyre used on different locations(19&34) - 19 mostly on turret top due to impact angle, 34 on UFP, sides, turret front.
As I said in my post, there are changes between Duplet-2M and Nizh-1M, especially in the charges that they use.
The top charge is from Nizh-1M while the bottom is from Duplet-2M, which is significantly larger than the Nizh-1M charge. Already from this increase in the height of the tile from the bigger charge, we can tell Duplet-2M won’t fit into a standard Kontakt-1 case, Nizh-1M already barely fits.

ХСЧКВ-34 and 19 are charges. Duplet is installation in multiple plates, Nizh in single.
have you seen entire video, from which that picture(screenshot) was taken? that’s ХСЧКВ-19&34 as seen in video. ERA charges themselves(ХСЧКВ) doesnt have naming like nizh or duplet. nizh and duplet are installations of ХСЧКВ in different forms.
ХСЧКВ-34(which you try to call as duplet)
SR said so, i cant see any reason why it wouldnt. aswell as information about ХСЧКВ-34 - all block are 36 ±1.5mm. K-1 boxes can be different, but from quick google search it tells that UFP&TurretFront ones are 40+MM.
Keep in mind, that K-1 installation is quite… funny. and it’s not only ERA charge
