Product details

0.100" Pitch, Dual-Row, Right-Angle Breakaway Header

The 77317-103-12LF: Mating contacts are gold GXT™ over nickel, 30 µinch thick — rated for 500+ mating cycles without wear-through. The UL94 V-0 thermoplastic housing suits equipment inside enclosures requiring flame-rated components.

Unshrouded Design and Breakaway Construction

The mating receptacle must provide those features. Push-pull fastening — no locking latch. In vibration-prone environments, the mating connector should have its own retention (e.g., a locking ramp or friction lock) to prevent backed-out terminals.

Board Layout and Footprint Notes

Right-angle orientation means the header body sits perpendicular to the board edge.

Frequently asked questions

Is 77317-103-12LF shrouded or unshrouded?

Unshrouded — no plastic shroud around the pins. The mating receptacle must provide keying and polarization.

Are there pin-compatible alternatives to 77317-103-12LF in the BERGSTIK® series?

The 77317 series includes multiple breakaway headers with the same 0.100" pitch, dual-row, right-angle footprint, but with different plating (tin vs gold) and position counts. For a direct gold-plated replacement, the 77317-103-12LF is the listed variant; other 77317-103-xxLF parts differ only in position count.
