Product details

The 77311-822-02LF: No official second-source cross-reference exists, but the BERGSTIK® series includes several 2-position variants with identical pitch and current rating.

Comparing the 2-Position BERGSTIK Options

The 77311-822-02LF shares its 0.100" pitch, 3A rating, gold mating finish, and unshrouded design with siblings 77311-824-02LF, 77311-802-02LF, and 77311-818-02LF. The difference is the overall contact length: 0.525" (13.34mm) for the 822, vs 0.480" (12.19mm) for the 824, 0.465" (11.81mm) for the 802, and 0.450" (11.43mm) for the 818. The 822's longer pin gives more reach through a thicker board or a taller mating receptacle.

Frequently asked questions

Is 77311-822-02LF a shrouded or unshrouded header?

It is unshrouded — the pins are exposed with no plastic shroud around them. This mates with a standard female receptacle housing and allows board-to-board stacking with a low profile.
