Grand oxygen sensor failure 1.6

Hello I need help ... I have a Grand Vitara 2007 1.6 3p and I threw an alarm of Chek Engine
I went to scan the car and throw that an oxygen sensor that is connected to the Catalitical did not work, the B2 or Bank 2 was not operational for which it throws me high level of gases ... the question is, can I change the sensor for one Bosch (alternative) or do I have to buy the original?

If you can replace it with an equivalent of any other brand since the Chevrolet brand is Acdelco. You just have to see that they coinsidate in cables, colors and the connector must be the same. There are two types of oxygen sensors, which is leaving the escape multiple to the catalyst and the one after the catalyst. They are of different characteristics. EYE.

Thanks for the help
