uP0109: 2A Ultra Low Dropout Linear Regulator equivalent substitute

[bilux]

Hello everyone,
I want to find a replacement for uP0109 8pins, and i found this parts:

uP0109 is "2A Ultra Low Dropout Linear Regulator"
RT9199 is "Cost-Effective, 2A Peak Sink/Source Bus Termination Regulator"
FP6137C is "2A BUS TERMINATION REGULATOR"

can replace uP0109 by RT9199 or FP6137C ?

I replaced the uP0109 with FP6137C and it worked just fine for future references (I'm not sure how long it will work though)

uP0109 appears to be manufactured by https://www.upi-semi.com

This motherboard has a DDR VTT Power section that identifies the IC as "NCT3103S co-lay NCT3102S/UP0109":

Thanks for your compatibility info. However, note that there is possibly a difference in pins 5, 7, 8.

Thank you truclacicr for this information, and you are correct the uP0109 is supposed to provide termination voltage for DDR memory system, but in my case the uP0109 is generating the +3V3_DUAL for H61MGV3 motherboard and all the pins 5,6,7 and 8 are connected together. So you are correct and this my not work in different scenario.
