200mA is equivalent to 0.2A if you throw a 2.0A adapter on the box, you will likely fry it.



NO.

It is the VOLTAGE requirement that must not be exceeded.

The unit will only draw the amount of amperage it needs to run properly at the required voltage, and since the 2.0A adaptor is certainly able to supply 0.2A or 200milliAmps, as long as its voltage rating is not exceeded, it will be happy.

BUT -- there are some other considerations that are very important. POLARITY of the connector may or may not be the same as the Polarity needed for the device. That is the little marking of + and - next to the jack on the target device. If you use a Walwart supply that has the correct Voltage limit and supplies enough or more Current, it still could instantly damage your device if the + and - Polarity of the power is switched around. Most Wallwart supplies are marked as to the plug polarity wiring, make certain that it is the same as the markkings on the target device.

One last item, the only supply out of the two that *might* work here would be the 2.4v DC @ 2.0A -- BUT it does not deliver the full 3VDC requirement. The device may operate, but you are taking the chance that some components may be running in a brownout condition, because there is 0.6VDC difference between the supplied 2,4VDC and the required 3.0VDC. If the unit uses motors for such things a tape transport, it will likely be running too slow at this voltage.

My answer would then be that, out of the two possible walwarts given by the OP, NEITHER would be a proper choice for this device.

The good news is that you can probably find a generic supply at places like Radio Shack, etc.
