i come to know this from that thread.

The 16F877A is a newer part. It's FLASH programming is faster (and different) than the 16F877.
The 16F877A also has a pair of comparators which must be disabled (on by default) if you want it to preform like a 16F877

As for ICD they are both the same, the A will program slightly faster and there is no need to use the non A version.

Both have been superseded by the new 16F887

its really helpful but i want to use 16f877 in place of 16f877A. can i use it as it is pin compatible?

Yes, as long as you don't need the extra comparator which is only in the 'A' version.
