I'm trying to pin down this component
Googling has got me to these two but I can't work out the difference or if they match.
Really appreciate some help IDing it. Thanks

Since it's part of a rail gun, it's very likely to be a Thyristor (Silicon Controlled Rectifier), though since there isn't an obvious gate connection, it could be a diode as well. I'm guessing the package is TO-48 or TO-65, but it's tough to be sure.
The board designators seem to be following IEEE STD 315 (kind of).
CR or D: Crystal rectifier (Diode) T: Transformer.
My guess is that this is a common mode choke on the power supply lines.

According to the Texas Instruments datasheet, the only difference between the two part numbers is how the chips are packaged:
The actual chips themselves are identical. They're both octal transparent D-type latches in a 20-SOIC package.
If you are hand-soldering or doing a small-batch, they are completely interchangeable.
If you are doing a large-scale assembly using automated equipment, you'll choose the -DWR part if your assembler/machine expects the parts on tape-and-reel and -DW if the machine expects to be fed from a tube.
