Position count across the USB-A series
Within the USB-A series the USB-A-S-F-W-SM2 (4 contacts, tray) sits alongside the USB-A-S-F-W-SM2-R-TR and USB-A-S-F-W-SM2-TR — all share the same 4-contact count, gold plating, 1500 mating cycles, and USB 2.0 specification; the difference is packaging: the -R-TR and -TR versions ship in Tape & Reel, while the -SM2 ships in a tray.
