I haven't bought things before for circuitry, but now I already completed my class for it in high school.
I'm trying to buy component parts for a certain schematic diagram that tells me I should get the following: AD8221
I'm pretty confused over model naming conventions. I've looked at the Analog Devices product list for these two and I found that there are several variations. For AD8221, what would be the difference between the AD8221ARZ and AD8221BR other than just cost and RoHS compliance for AD8221ARZ? The AD8221BR is about $1.30 greater in price (for a package of 1000). Wouldn't a type of compliance to something, RoHS for example, cost more? If so, then what the AD8221BR have that AD8221ARZ doesn't? I would also like to know what REEL and REEL7 is.
Here is the product search link:

Additionally, since the variation is on packaging(size, form, and composition), there wouldn't be in a circuit incompatibilities of different packagings of the same chip in terms of I/O right?
