Yes, though it depends on the circuit. Push Pull would be best as then the bias currents cancel on the transformer.

A pair of these on a heatsink would be suitable to replace the 12V DC converter of the FT101 series. The FT101Z, FT101ZD etc has the windings on the transformer, but lacks the connector.
