Indentifying a 6 pin IC

I have an IC- supposedly purchased as a ZXTC2045E6TA-6 pin SMD, but the markings on it show N4 99 t.
I use this IC to repair mobile mono blocks for KICKER. Normally the markings are 2045.

I've looked online and found a code list but cannot find a match between the two.
Can anyone tell me if they are the same part and where I can find a good code list?
 
It's just a PNP and an NPN in a single case. You could use the diode tester of a multimeter to make sure if they are ''electrically identical'', so to say. You'll have to test them in-circuit to see whether they perform as expected, but this way you can at least rule out that they're something totally different.
 
Diodes Inc data sheet says the markings on the ZXTC2045 are supposed to be '2045'. I suppose it could be a similar device by a different manufacturer, but who knows... Digikey shows 134k in stock for the ZXTC2045E6 (Digikey P/N: ZXTC2045E6CT-ND). Why not just buy from them and know you get legit parts? If you only need a couple you might even be able to get samples directly from Diodes Inc.

Number one this is not my first rodeo
Number two I know what the 2045 is
Number three I run the electronic repair dept and purchased thousands of parts including the 2045 from only reputable vendors

My plan is to check the device marked N4 99 t but wasn't able to yet. My hope was that someone on the parts sub forum might recognize the marking or knew where there might be a website with a comprehensive code list.

Yes, I considered the car audio forum and Perry Babin knowing the answer in short order and will post there as well.

It's possible the cut spool may have gotten put into the 2045 static bag, either in the shop or at the vendor. It's been awhile since I purchased this part.

Yes, I have ordered more ZXTC2045E6 from Arrow and have already shipped.

Thanks, Bill
 
This is the part in question. Maybe someone recognizes it.

Thanks, Bill
