Suitable FPC Connector for SD Card Contacts Teensy 4.0

Hello, I am looking for a connector to solder on to the bottom of the new Teensy to enable me to use the SD card pins. The recommended connector AFAIK is this - https://www.digikey.co.uk/product-detail/en/amphenol-icc-fci/609-1788-1-ND. However, this is discontinued (although still in stock for now) so does anyone know of a suitable replacement?

Thanks,
Louis

Edit - I'm confused some websites (like Mouser) say it is end of life but the manufacturer and Digikey says it isn't.

For those of us in awkward places (like anywhere outside the US :) it would be great if the connector could be an option in the shop here when you buy a T4... I'll be getting a few to use and replace some 3.5's for a racing logger... I currently have "enough" cpu but I have a predictive lap time function that currently can't be comfortably done in realtime. An SD card is a requirement for me for the logging, so I am waiting until it becomes apparent what the smallest, supported Micro SD, (Or SD even) solution looks like.

That's exactly why I didn't delete my question after finding that the connectors aren't discontinued (I think), these connectors are a pain to get hold of outside of the US. If there was a UK distributor or a suitable alternative, that would be great!

Edit - TallDog's flex PCB looks great (https://forum.pjrc.com/threads/57122-Teensy-4-0-Breakout-Kit) but once again it will be a pain to get hold of outside of the US unless you are willing to pay for expensive shipping!
 
Farnell has then in stock but only in the US which means you have to pay an extra £15.95, even if you only buy one!
 
Sorry to resurect this thread, but this information may be useful to the people in the UK.

uk.rs.online have free postage and sells these FPC connectors:

The first fits the solder pad layout on the teensy 4 but the lock tabs are a little too wide to fit between the header pins if used. The tabs are only plastic though and can be trimmed with a sharp knife/scalpel. The second is narrow enough to fit between the header pins, but the body ground pads don't match those on the teensy. This means that the electrical connections take all the cable movement strain. Overall, I think the first type is better.

RS also sells this locking SD card holder which is good:
