See there are two brands mentioned AMS and HTC. Both of these brand’s power IC is used for their different use cases.
Like for STB repairing AMS 117S ICs are used while for repairing of Digital Headend Devices H 1117S is used.
But Why So ?
First Reason :
Because HTC power ICs perform better than AMS power ICs. For digital headend devices like QAM , Encoder and IRD etc HTC is always used because these are heavy work device which runs 24*7 .
While on the other hand STB runs 5 to 6 hours in a day which does not have heavy load to run so people use AMS brand power ICs for it.
Second Reason :
AMS brand power ICs are cheaper than HTC power ICs. Like in india AMS brand power ICs cost around 4 INR after importing while on the other hand HTC power ICs cost around 8 INR per piece. That can be vary little bit.
NOTE : It does not mean you can not use HTC power ICs in repairing of STBs. While you can use HTC power IC in repairing of STB that is better solution.

If you repaired 100 STBs having same power IC problem. Then after some days you are getting near about 20 to 30 complaints then it means your power ICs are duplicate.
While on the other hand,
After repairing 100 stbs if you are getting 2 to 3 or less than that complaints then you are using original ICs.
