where can i get a STP5N90 for a pace by prime

[astra 1D]

the power supply has failed on my pace by prime analog satellite receiver
the part i think i need is STP5N90 dose any one know were i can get one

thanks

Ebay is probably about your only hope. The vast majority of those receivers will ahve been scrapped over a decade ago.

yes i have bean looking on ebay but all it comes up with is DURACELL battery.

that is but the web site looks a bit sketchy have you use it before

Minimum order is Eu50 on that site.

ok i will look in to it
but the receiver only cost my 1£

Can you post a picture of the PSU and one of the connector ?

I have boards here that may be a close match though it may also highlight components that could bring the receiver alive if replaced.

It appears they can also be sourced from Aliexpress.

OTOH, the data sheet is here https://alltransistors.com/mosfet/transistor.php?transistor=5432 and
some equivalents/near equivalents are listed here: https://alltransistors.com/mosfet/c...uds=900&ugsth=4&id=5&qg=75&rds=4.8&caps=TO220

With that info you might then be able to find something that would do the job, and is more easily obtainable??.

Will this work,even though it’s not the exact part number:STP6NK90Z Marked P6NK90Z ST Trans MOSFET N-CH 900V 5.8A 3-Pin TO-220 | eBay

Have you compared the specification characteristics line-by-line - if so are they close &/or are there any significant substantial differences?

 

[astra 1D]

i am not sure if it will work i will look in to it

Here’s the picture of the psu

Looks like the Primary side of most simple Switched Mode Power Supplies and I assume that the required transistor fits on the board in the position marked "U1" - OTOH, doesn't really give any info that would help in choosing a replacement transistor as that would depend on the values of the components around it. And, of course, C3 & C4 should also be replaced as a matter of course (by High temp 105C components!) as well as VDR1.

NB: if not already done, you should check the Primary windings on T2, and whether D1 to D6 D8 are still OK (may be short-circuit). The diodes can be replaced (by same types, especially D5/D6 D7/D8 which may be High Speed types!) but if T2 is damaged then the PSU is probably unrepairable as it was probably a bespoke component that is unavailable (unless you could find another working receiver of the same/similar type!)

Thanks for the help
I will check T2 and see if that is to blame

does anyone know where i can get the manual and service manual for this receiver

Needs the exact model number for anyone to be able to help you with that !

pace mss1000 i think

Presumably the thread title refers to the Prima by Pace

Post a photo of the actual receiver.
