The Amphenol FCI BERGSTIK 75844-117-72LF is a 72-position (2x36) unshrouded male pin header on a standard 0.100" (2.54mm) pitch. It is a breakaway-style header, meaning the pin strip can be snapped to shorter lengths for custom circuit counts — though this specific variant ships fully loaded with all 72 positions. The through-hole solder termination and dual-row layout make it a direct fit for legacy 0.100" grid boards, prototyping grids, and backplane-style interconnects where a high pin count is needed without a mating shroud.
Key features and ratings
Rated 5A per contact at 110V, the current capacity is moderate — enough for signal and moderate power distribution, but not for bus-level power rails. The 30.0µin (0.76µm) gold GXT plating on the mating surface is a hard gold alloy that handles repeated mating cycles and resists corrosion in industrial or outdoor environments. The phosphor bronze contact material provides good spring properties and conductivity. The operating temperature range of -65°C to 130°C covers most harsh-environment applications, from cold storage to hot industrial cabinets. The UL94 V-0 thermoplastic housing ensures the connector meets flame-retardancy requirements for equipment inside an enclosure.
Mating and board layout
As an unshrouded header, this part mates with any standard 0.100" (2.54mm) pitch dual-row female socket or IDC receptacle — the BERGSTIK series is widely used with matching ribbon-cable sockets and box headers. The 0.335" (8.51mm) mating pin length provides good wipe length for reliable contact. The overall contact length of 0.852" (21.64mm) includes a 0.417" (10.59mm) post for through-hole soldering, which suits standard 1.6mm PCBs. The 0.100" (2.54mm) row spacing mirrors the pitch, keeping the footprint on a uniform grid. No board lock or alignment feature is present — the through-hole solder joints provide the mechanical retention.
Sourcing and lifecycle
The 75844-117-72LF carries an Active lifecycle status from Amphenol FCI — full production, no end-of-life notice. No official replacement or cross-reference is recorded, but the BERGSTIK series includes many 72-position breakaway headers — verify the plating grade and pin length against your BOM before committing.
