The FCI BERGSTIK® 93690-410-08LF is an 8-position, dual-row unshrouded breakaway header on the standard 0.100" (2.54mm) pitch. Key features include a press-fit and solder termination option, tin-plated mating contacts with a heavy 120.0µin (3.05µm) finish, and a UL94 V-0 thermoplastic housing. The 5A per-contact current rating and 110V voltage rating suit it for signal and light power duty inside enclosures.
The 0.100" (2.54mm) pitch is the classic breadboard-compatible spacing — it matches standard perfboard and legacy prototype layouts, and the dual-row format with 0.100" row spacing gives a square grid for routing. The 5A per-contact rating is the thermal limit at room temperature; in practice, the tin-plated contacts and 0.100" pitch mean this header is best used for signal lines or moderate power distribution where the total current per row stays under the derating curve. The 120.0µin gold-equivalent tin mating finish is a heavy plating that handles repeated mating cycles well, though tin is more prone to fretting corrosion in high-vibration environments than gold. The press-fit termination option means the header can be inserted into plated-through holes without solder, which is useful for backplane assemblies where rework or selective population is needed.
