SS34 DIODE CAN BE REPLACE WITH M1 DIODE?

I have pcb board of bluetooth speaker.
It has ss34 diode.
The question is,it can be replace with m1 diode?
Ss34 diode is Schottky diode and
M1 diode is rectifier diode.

No.
SS34 is a Schottkt diode. M1 is not.

1N5822 is a possible replacement if it is available in SMD package

Short to ground.
In my case,i check first the schottky diode in directory diode app and test with multimeter set diode mode but seems good.The 3.7 voltage are present but in power rail on Schottky diode voltage is going droping... I check all resistors,resistors are good.after i check all smd caps but there's one short caps(ceramic capacitor)I remove it but badly dead....after I remove the bad caps logic board is power on....IMG_20210318_213703.jpg
