Compatibility is doubtful: I just tried to register a D1680 handset to a D1580 base and it failed. Both the handset & base are "known good" but they will not pair together.
It does not hurt to try, be sure your handset is de-registered (hold the [END] and [ # ] keys at the same time until the screen displays the deregister instructions) and the battery well charged.
