Broken bed heating connector

Hello,

A few weeks ago my MK2.5S started to randomly display MINTEMP BED during printing or to heat the bed slowly than usual. Unfortunately, yesterday just didn't warm the bed anymore (LED does not light). Checked the fue and it was ok, but when I tried to take out the connector to the Rambo board, this what I've seen. Where can I find a replacement connector (both male and female), as I want to use only original parts.

RE: Broken bed heating connector

From the BOM:

"0395311002" "Conn - 5.08mm Pitch Fixed" "X13" "MSTBV2" "0395311002" "0395311002"

From a subsequent Web Search:

64, X13, Digi-Key, WM7837-ND, Molex, 0395311002, 2POS, 1, 0395311002MSTBV2Conn - 5.08mm Pitch Fixed, 2 Position Terminal Block Header, Male

From searching Digi-Key:

https://www.digikey.com/en/products/detail/molex/0395311002/1280688

From the product spec linked by DK:

PRODUCT SPECIFICATION FOR ESE EUROSTYLE TERMINAL BLOCKS
395XX PLUGS AND PCB HEADERS

And doing a bit of filtering on Digikey ...

https://www.digikey.com/en/products/filter/terminal-blocks-headers-plugs-and-sockets/370?s=N4IgjCBcoBw1oDGUBmBDANgZwKYBoQB7KAbXACYwBmcgNhAF0CAHAFyhAGVWAnASwB2AcxABfAgFoI0EMkjps%2BIqRDkqjFu0ggxo0UA

And digging a bit deeper one part at a time it sort of looks like this one:

https://www.digikey.com/en/products/detail/molex/0395200002/1280640

Which lead me to this datasheet:

https://www.molex.com/pdm_docs/sd/395200002_sd.pdf

Which makes it look like it is the correct part. But no warranty. Try Prusa support CHAT on their store. They should be able to help.
