I have one of each lying in front of me. They are quite different. The 10811 
is 3 3/4" by 2" by 2 3/8". It has a PC edge connector with 15 contacts 
protruding from the case.
The 49-61C is 3 1/2" by 1 15/16" by 1 15/16". It has 6 individual thru-case 
pins to a short pigtail lead with a 5 pin mini connector at the end.
The physical mounting method for the two units is entirely different.
I have no info on the electrical specifications of the 49-61C (except those 
derived from the specs of the 8568B SA.
