    The former device requires a max of 5mA to operate, the latter 35mA. It may not work if the circuit does not provide sufficient gate drive. Try looking for a sensitive gate triac.

    And please don't cook your snake.

    edit: typically it requires 5mA in the most common quadrant (the one specified for the original device) so it may work, and it probably worth a try.
