Invalid DB Instance class: db.t2.micro

Why can I not create a database of size db.t2.micro in CloudFormation? Here is my template:

Resources:
  Database:
    Type: AWS::RDS::DBInstance
    Properties: 
      AllocatedStorage: 20
      AllowMajorVersionUpgrade: No
      BackupRetentionPeriod: 7
      DBInstanceClass: db.t2.micro
      DBName: myDB
      DeletionProtection: no
      Engine: mysql
      MasterUsername: admin
      MasterUserPassword: superSecret
      MultiAZ: no
      PubliclyAccessible: yes
      VPCSecurityGroups:
        - !Ref SG

And the error that I am getting is:

Invalid DB Instance class: db.t2.micro (Service: AmazonRDS; Status Code: 400; Error Code: InvalidParameterValue; Request ID: ????; Proxy: null)

Any suggestions are appreciated.

You can use the following AWS CLI command to check whether a DB instance class is orderable in a particular AWS region:

aws rds describe-orderable-db-instance-options --engine mysql --db-instance-class db.t2.micro --region eu-north-1

In this case, it returns

{
    "OrderableDBInstanceOptions": []
}

This means that the db.t2.micro is not orderable in eu-north-1.
