broke a component :(

i was trying to remove a heatsink from my raspberrypi 4 and it sliped and knocked half the chip off i dont know what it is and was wundering if i can replace it myself ?? in the pic included its the one curcled in red

My guess is L5, but needs confirming.

Looks much to far away from the dc-dc converters IC to be one of the inductors around it.

gordon77's guess looks reasonable to me. dustdragon linked a Discord file upload and presumably its server doesn't like the referrer being this forum so it doesn't load. Press quote on their post to see the URL which you can copy paste.

It seems to fit the schematic.

My assumptions...

How many 5 legged devices and inductors like that on the board ?

Answers : 1 and 5, and it isn't L1-L4

sorry that the pic didont work i have just taken some pics myself and will uplaod them

it is between the usb and the audio jack

[gordon77]

Your pic did work, l still think it's L5.

[dustdragon]

i think you might be right but what is L5 ? some form of inductor ?

Have you tried booting your Pi?
To me, it just looks like the carbon core got chipped. I don't see any bare copper, so that inductor may still work.

I wrote that without looking at the schematic. Having now done so and seen that there is a second dc-dc converter IC (ie in addition to the one near the power input socket) I concur that the damaged component is very probably L5.

i found a component that might work as a replacement can ane one please conferm its right ?

part number "LPWI252010B2R2T"

https://www.littelfuse.com/products/ind ... b2r2t.aspx
its the right size and has what im gessing is the right stats

[dustdragon]

can some one conferm that this part " https://www.mouser.co.uk/ProductDetail/ ... BlHL6h73I= " will work to replace L5 ?

I can confirm that the spec appears correct, as far as it matches the info on the schematic.
Will it work? That depends on too many unknowns:

• Is any other part of the Pi damaged?
• How good is your soldering ability?
• How good is your soldering equipment?
• Is the phase of the moon correct?
• Is it your turn for a lucky day?

The operation was a success, but the patient died.
