TL331: Voltage follower OP to replace TL331

Part Number: TL331

Hi,

My customer needs a voltage follower OP, but incorrectly choose a comparator (TL331) on their board with schematics below.  Therefore, they need a pin-2-pin compatible OP to replace TL331, but I can't find an exact fit.  Can you check if we have such a drop-in replacement OP for them?  THanks!
