Similarly, my company just redesigned a product after running out of an IC that's been on order for many months, still without an estimate on delivery by the distributor. We redesigned it to use another chip we had in-house, intended for another product, but that product sells for much less and is in less demand, so... We initially thought we could move pins around in firmware, and the parts have the same footprint, so it seemed possible, but they were different enough that we had to rev the PCB. Now we're waiting for PCBs and crossing our fingers that they will test out.
