Product details

The 77313-401-70LF: The unshrouded design lets you snap the header to length for non-standard position counts, though this one ships fully loaded. For signal-level loads — logic, I/O, low-power distribution — the current ceiling is well within the housing's UL94 V-0 thermoplastic limit.

Through-Hole Mount and Board Fit

The solder posts measure 0.095" (2.41 mm) long — enough for a standard 0.062" PCB with good through-hole wetting.

The base product number 77313 covers the family; this specific variant carries the -401-70LF suffix indicating the tin-plated, 70-position, through-hole configuration. No official pin-compatible replacement is listed — the BERGSTIK series is broad, but each position count and plating option is a distinct order code.

Frequently asked questions

Is 77313-401-70LF RoHS compliant?

The LF suffix in the order code indicates lead-free / RoHS-compliant termination finish. The tin plating on the contacts and posts is consistent with RoHS requirements.

What is the closest pin-compatible alternative to 77313-401-70LF?

Within the BERGSTIK series, other 70-position dual-row unshrouded headers with the same 0.100" pitch are mechanically interchangeable, but the contact plating (tin vs gold) and post length vary by suffix. Confirm the mating-cycle requirement and board thickness before substituting.
