Capacitor physical size

Jay_que , 08-09-2022, 09:29 AM
Hi everyone,

I have started working on ISL6236A( altium essential course), I noticed,I have selected wrong capacitor size instead of 0805 1uF,50V I used 1206 1uF,50V.

Is it okay to use 1206 instead of 0805 capacitor if specific for both are same except physical size ?

I am new to Altium, could you please provide suggestions.

Thank you

Wrong in what sense?
- Footprint matching BoM?
- Does the bigger one fit the space?
- DC bias?
- Inductance?
- Power dissipation rating?
- etc.

I have not done the course so I do not know if it would be a physical problem there.
Often it is even possible to solder a 1206 on a 0805 footprint. Difficult, but possible. Just don't do it for mass production.

You can try to work with 1206 but it may be harder to follow the tutorial step-by-step.

PS: Personally, I would just create a new 0805 component and update the design. It is a 10min job.

Yes I’ll update so it’s bit easy to follow.
