The Amphenol 95687-120HLF is a 20-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect applications. It uses a 0.100" (2.54mm) square pin grid on both pitch and row spacing, which is the standard footprint for legacy and new designs alike. Rated at 5A per contact with a 110V voltage rating, it handles typical signal and low-power distribution duties. The mating contact finish is gold or Gold GXT™ at 30.0µin (0.76µm), giving it good corrosion resistance and a solid mating cycle life for field-serviceable assemblies.
Key Specs and What They Mean for Fit
The 20 positions are fully loaded across two rows, so the BOM circuit count must match exactly — there are no unpopulated positions. The 0.100" pitch is the de facto industry standard for 2.54mm prototyping and production boards, meaning this header drops into a wide range of existing layouts without a footprint change. The unshrouded design (no plastic wall around the pins) means the mating receptacle must provide its own alignment; it also allows the header to sit flush against the board edge for tight stacking. The through-hole solder termination gives a strong mechanical anchor, preferred over SMT when the board sees vibration or repeated cable strain.
Plating and Current Rating
The 5A per-contact rating is typical for a 0.100" pitch pin header at room temperature. Derate above 25°C per the manufacturer's curve if the board runs hot. The gold or Gold GXT™ mating finish at 30.0µin is a mid-to-heavy plating grade — it supports hundreds of mating cycles without exposing the base phosphor bronze, making it suitable for test points, programming headers, or any interconnect that sees periodic disconnection in the field.
