The Amphenol 75160-150-20LF is a 20-position, single-row, unshrouded male pin header from the BERGSTIK® series. It uses a 0.100" (2.54mm) pitch — the standard grid for legacy through-hole board-to-board interconnects — and terminates via solder to the PCB. Rated for 5A per contact, it carries a 30.0µin (0.76µm) Gold GXT™ finish on the mating surface, which gives it a solid cycle life for repeated matings in test, programming, or modular board stacks. The operating temperature range spans -65°C to 130°C, and the thermoplastic housing carries a UL94 V-0 flammability rating. This header is intended for board-to-board applications where the mating receptacle is not shrouded — the push-pull fastening type means it relies on the friction of the pin-receptacle interface for retention.
What the key ratings mean for your fit
The 0.100" (2.54mm) pitch is the defining footprint dimension — it places the through-hole solder tails on a standard grid that matches legacy BergStik receptacles and many other 0.100" pitch ribbon-cable or discrete-wire IDC connectors. The 20 positions are all loaded, so the BOM line count is exact. The 5A per-contact rating is generous for a signal header; at that current the limiting factor is usually the temperature rise in the harness or the PCB trace, not the pin itself. The 30.0µin gold GXT plating on the mating surface is the feature that distinguishes this from commodity tin-plate headers — it supports more mating cycles and resists corrosion in environments where the board stack is frequently separated and re-mated.
