Actually, the 5 pin insulated package was used by Samsung and continues in use at Fairchild for their integrated off-line switching regulators.
If it's the primary switch, you might find a functional equivalent there.

Power Integrations make some like that IIRC too.

The closest Power Integrations package (with a staggered switch drain pin) has six pins altogether, and has the drain pin on the right side of the TO-220 body.
The Samsung package has five pins, with the drain on the left side.
