Product details

Board-to-Board Header, 34 Positions, Breakaway Style

Termination is surface mount, so this header reflows with the board in a single pass. No through-hole solder tails to hand-solder or wave-solder — the SMT pads are on the bottom side only.

Mating contact finish is gold GXT at 15.0 µinch (0.38 µm) minimum — a hard gold alloy that handles 200+ mating cycles without exposing the phosphor bronze base metal. The tin-lead solder tails are a one-time joint — rework is possible but the post finish is not designed for multiple reflow cycles.

Sourcing and Lifecycle — Obsolete Status

The BERGSTIK series continues in production with other position counts and plating options, but this exact 34-position, SMT, gold GXT variant is discontinued.

Contact base metal is phosphor bronze — good spring properties for the breakaway retention beams, though the primary retention comes from the SMT solder joint, not the contacts themselves.

Frequently asked questions

Where can I buy 95278-801-34?

This part is obsolete and not stocked in volume. Submit a BOM quantity request for a sourcing check.

Is 95278-801-34 obsolete?

Yes, Amphenol ICC (FCI) lists this part as Obsolete. No direct pin-compatible replacement is published by the manufacturer. For a BOM that requires this exact footprint, the remaining inventory in the supply channel is the only option.

What is the pinout of 95278-801-34?

It is a 2-row, 34-position header with all positions loaded. Pin 1 is typically marked by a chamfer or notch on the insulator body — refer to the BERGSTIK series drawing for the exact pin numbering convention. The mating interface is standard 0.100" pitch, so any 34-position 0.100" IDC or box receptacle with 2 rows will align.
