Unkown smd part D14JL

neo2000:
Hello, I need help identifying 2 blown parts from a Li-Ion battery charger. It has slots for 8 batteries charging up to 2A. I removed the blown parts in the picture already, but they are ale the same on this side of the pcb. It's a sot-23 housing with the label D14JL as they are used to drive the coil, they might be mosfets, but the internet gave no hint. I would be pleased if someone has any glue with part this could be.
Thanks in advance. Regards Timo

wraper:
Could be Si2321DS. D1 device code and total number of symbols do match.

neo2000:
Ok, I tried another type of p-Type Mosfet as the SI2321DS. I used a SI2301 P-Type 20V 2.8A. My immediate problem was a dead short when powering up. In my opinion these should be N-Type as the drain has +9V and +5V on both sitting next to the coil?

fzabkar:
Can you show us the complete photo to provide some context? Which part drives the gate/base of the MOSFET/BJT?

neo2000:
Now, I have done what I should have done first  |O. I removed a working part and put it in the device tester. The result is shown in the picture. Any advice which replacement part I can use to replace the blown ones?
I also measured the drain of both near the coil, one is 5V, this should be for charging NiMH and the other one has 9V this should be for charging Li-Ion as on the source are 4.2V when charging Li-Ion.
