TOP 223/224 substitude for TOP200

Posted by: hnyyee on

I am repairing a power supply and it uses a TOP200YN.
I have tried all usaul resources to buy one but can only find TOP223 and TOP224 at Farnell Components. So, could I buy the TOP223/224 to substitute the TOP200.

Thank you for your help.

Yes the TOP223 is a close match to TOP200. However the current limits and switching frequency if these parts do not match exactly. Please verify that the transformer flux density is below 3300 Gauss during operation and below 3900 Gauss worst case (transient and startup)
