Anderson SB120 Connectors

What’s the difference between the 6810G3 and the 6810G3-BK connector products? Also, what is the difference between the 1319 and the 1319-BK contact products? Looking at the descriptions, they seem to be identical, beside cost.

Thanks

Good evening, Tony. Welcome to Digi-Key TechForum.

“-BK” indicates thousand-piece bulk pack, while a blank suffix is 25-piece bulk pack. The connectors themselves are identical.
