ODROID XU4 REV 0.2 20191126 defectuous L15 Inductor

Post by antonio.valbuena »

Hello,

I have various ODROIDs XU4 REV 0.2 20191126 with a defectuous L15 Inductor.

I desire to repair this boards removing the L15 Inductor and installing a new one.


I succesfully performed this repair with ODROID XU4 REV 0.1 20151201 back in 2018.
L15 inductor installed on ODROID XU4 REV 0.1 20151201 is Part.Number:LQH44PN100MP0L OEM:Murata but I noticed ODROIDs XU4 REV 0.2 20191126 installs new inductor (new inductor has a noticeable height increase)


The value of L15 Inductor is the same as previous version: 10uH (checked schematics) but I desire to know Part.Number and OEM to assure the performance


Does anyone know ODROIDs XU4 REV 0.2 20191126 L15 Inductor's Part.Number and OEM?

Thank you,

Antonio Valbuena

You already asked it 2~3 years ago.

Can you take a picture of the defective L15 inductor and show us?

Anyway, we will get back to you the day after tomorrow since tomorrow is our national holiday.

Dear Sir/Madam,

Thank you very much for your supports.

Correct, I asked back in 2018 ODROID XU4 REV 0.1 20151201 inductor L15 Part.Number and OEM.
Thanks to ruppi's reply, I succesfully performed the repair.


But I noticed ODROIDs XU4 REV 0.2 20191126 installs new inductor.
New inductor has a noticeable component height increase.

New L15 iductor is SWPA4030S100MT and manufacturer is Sunloard.
This part is sold at Digikey.

You can also use the existing Murata inductor since they have the same foot print as well as the same characteristics.

Hello ruppi,

Once more, thank you very much for your support.

Will buy the inductors and proceed with the repair.
