Guys, please help with advice. 1989 E34 525i.

My A/C compressor is shot, and I ordered a replacement one. The part that arrived Bosch P/N 64521377943 seems to be different to what is in the car. The original (now dead) unit is Seiko P/N 64521386948. I don't know if the new part is okay to install. Can someone tell me if all is good?

Also, do I need to match a different accumulator as well for this replacement?

Can the Bosch compressor above be used with R-134a? The a/c system has been converted, but it had the now dead Seiko unit.
