Product details

Board-Layout Fit: 2.54 mm Pitch, 2 Positions

The 77311-819-02LF: That pitch matches standard perf-board, DIP sockets, and prototype grids — no custom footprint needed for a quick breadboard or a production run. The through-hole tails are 0.119" (3.02 mm) long, which clears most 1.6 mm PCBs with room for a wave-solder fillet. Use a mating housing with a polarisation key or a strain-relief clip if the assembly will see frequent reconnects.

Current and Contact Grade

That thickness is the industry standard for moderate-cycle applications — think 100–500 mates over the product life. In a field-service connector that gets cycled quarterly, that is decades of reliable contact.

Sibling Comparison: 77311-819-03LF

The 77311-819-03LF is the same BERGSTIK® unshrouded header, same pitch, same plating, same current rating — but with 3 circuits instead of 2. No other parametric difference between the two.
