Product details

Board-to-Board Header for Dense Parallel Routing

The 77317-812-64LF: Operating temperature spans -65°C to 130°C, covering automotive, telecom, and military thermal profiles.

Right-Angle Through-Hole Fit and Board Layout

The 0.268" (6.80 mm) mating pin length provides sufficient engagement depth for standard box headers or IDC receptacles. Insulation height of 0.190" (4.83 mm) above the board leaves clearance for trace routing under the header body.

The tin-plated solder posts (78.7 µinch) and gold GXT mating finish are lead-free per EU directive.

Frequently asked questions

What is the pitch and position count of 77317-812-64LF?

The pitch is 0.100" (2.54 mm) on both the row-to-row and pin-to-pin spacing. It has 64 positions loaded in a dual-row configuration.

What is the closest pin-compatible alternative to 77317-812-64LF?

No official cross-reference or direct replacement is listed. Other BERGSTIK headers with the same 0.100" pitch, dual-row, 64-position, right-angle through-hole configuration may be functionally similar, but pinout and footprint should be verified against the original.
