Identification – Identifying Lenovo W530 Fan Connector Type

I have been trying to identify the black connector in the picture. It is from an older Lenovo W530 laptop fan made by Delta. Unfortunately it appears Delta doesn't have a data sheet (I asked them) and the same part number comes with different connectors (or Lenovo custom ordered, modified, etc…). It doesn't appear to be the normal fan connector type I've seen before.

I obtained a Delta fan with the same Delta part number, but it has the white connector which is not a fit. I've gone through some of the connector id sites, but there are sooo many different ones and I haven't been able to find it. Hoping someone sees the black connector in the pic and can identify the family it belongs to?
Black connector is ~ 6mmx2.5mm and 3mm tall (not sure what the right terminology is…3mm from where the wires are inserted to the face that inserts into the board)

Have done a bunch of JST type connections in the past, so not a novice on crimping and such, but I need to identify the black connector type so I can get the materials to switch the new fan from white to black.

Thanks so much for any help you can provide.
