Not all DB instance classes are available for all DB engines. Also, in most cases bringing your own license or using an open source engine will maximize the amount of savings related to Reserved pricing. Similar to EC2 Reserved, with RDS Reserved you save money by committing to a 1 year or 3 year period for a particular RDS DB instance class and database engine.

How to Reduce Amazon RDS Costs with Reserved Instances | Parquantix

Reserved instances are a billing construct only.
If you buy a reserved instance for a m1.small in us-west-2a, all that means is that one of your on-demand RDS instances that's an m1.small in us-west-2a receives that lower hourly price (and incidentally, if you delete that instance and make a new one, the reservation's lower hourly rate just shifts onto the new instance). No instance is launched by reserving one.
