A/S system match/differences

I was trying to determine the difference between the A/S 4TTB3060D1000C and 4A7A3060D1000A.

Other than physical appearance, the only difference I noted was SOUND POWER LEVEL [dB(A)] of 80 for 4TTB3 and 75 for 4A7A3.

The quote I had is pairing the 4TTB3 with an AUH2D furnace and a 4TXCD061BC3HCB coil. Are these 3 components a proper match?

Thanks
