Hi.

Sorry, I don't know english well.
I wann fing longevity of this devices:
MT2800GS
CCR-1009-8g-1s-1s+
rb433ah
rb433gl
please help me.

What exactly do you mean?

lifetime (optimum age) of ccr-1009-8G-1s-1s+ ?
lifetime (optimum age) of RB433AH ?
lifetime (optimum age) of RB433GL ?

It works forever until it breaks. Keep it cold and feed it by quality electric energy and it will be working for ages.

Correct, If it does not break in the first 3-6 months it lasts for years.

Unless you're unlucky enough to get famous bulging capacitors. But it's only temporary showstopper, replace them and device is good as new.

Does Mikrotik products no have MTBF data?

No. But it is not important I would say. I am running some rb133 that work without any failure for more than 10 years.... Anyway to ask for mtbf is like to ask a car dealer how long will the car work... It will for the warranty period. If not then you will get new replacement for free. If it survives more, you have won in lottery... So. If you need to make a business decision, take the warranty period as the input for your calculation. Whatever else is guessing from a crystal sphere...

Well it is even worse, because it indicates a misunderstanding of what MTBF really is.
(in relation to "how long will it work")

Does Mikrotik products no have MTBF data?

a distributor in hungary annually shares RMA statistics - this is definitely not MTBF data - but all in all, MTBF is just a set lab values. you take the component's MTBF numbers and multiply them. there are big name vendors with peak MTBF values, and then sh*t just keeps breaking.

last year the notable things in AP's report were the following:
SXT 5nDr2: sold 7000+ pcs, RMA rate: 0.3%
SXT (other)> sold 1000+ pcs, RMA rate: 0.2%
RBLHG-5nD: sold ~1000 pcs, RMA rate: 0.3%
RouterBOARD 750r2: sold ~1000 pcs, RMA rate: 0%

again RMA rate does not necessarily indicate reliability, cause there's always user error in the picture.

during my last 5 years i had 2000pcs of various mikrotik stuff in my hands, most of them is still working as there were first installed, a little part of that was relocated/re-installed to some other place. now i can count on one of my hands the fatalities:

- 1pcs RB2011LS: broke after 1yrs, no way to restore, even routerboot doesn't load
- 1pcs RB250SW: broke after 5yrs of continuous operation w/o proper ventilation, the back of the device burned to yellow
- 2pcs RB850Gx2: DoA, will not boot, not even to routerboot

i'd say this is pretty much a great track record.

EDIT: attached actual report

I am running some rb133 that work without any failure for more than 10 years....

That RB133 was likely made before the RoHS directive (2006) required lead-free soldering that made electronics much less reliable. I too have many old devices still working, and many newer ones that failed. There are RoHS exemptions for telecommunication infrastructure where good old Sn-Pb solder is still allowed, but I don't know if any such equipment is still made at all. The new Pb-free solders have worse mechanical properties (crack more easily), higher melting temperatures (more stress on components during soldering), and the infamous "tin whiskers" that make short circuits.

Just replaced a cap in my RB750G. This is supposedly the better one (Suscon MG) but it's still crap. There is also yellowing on the case and PCB from the heat.
If you're concerned about longevity then after the warranty has expired change all crapcaps and arrange some ventilation. Caps should not fail so fast in these things, they should last at least 10-15 years.

There is your answer. Caps last longer if properly cooled. Sounds like your room is very hot, if the PCB has discoloring.
