Texas Instruments X suffix information

Looking for the difference between Texas Instruments part numbers LM358M and LM358MX.

The part number with the X is Tape & Reel packaging. The part number without the X is Tube packaging. So they are the exact same parts, just packaged differently.

Both of these part numbers contain Lead, and are Not Recommended For New Design. So the Lead-Free/RoHS compliant versions are LM358M/NOPB and LM358MX/NOPB
