What this connector is
The Amphenol FCI BERGSTIK® 75844-150-10LF is a dual-row, unshrouded breakaway header with 10 positions across two rows, designed for through-hole solder termination on 0.100" (2.54mm) pitch. Square male pins mate into the matching BERGSTIK® receptacle housing or IDC connector; the push-pull fastening type means there is no locking clip — the friction of the pin-to-socket interface holds the connection until the user pulls it apart. The style is listed as Board to Board or Cable — it seats in a PCB and receives a wire-to-board or cable-side connector on the mating face. Breakaway headers are valued in prototyping and production for their flexibility: individual pins can be broken off to create custom circuit counts without cutting traces or buying a different part number.
What the key ratings mean
Gold plating at 30.0 µin (0.76 µm) on the mating surface is a mid-thickness hard-gold deposit. Gold-over-nickel on the contact spring maintains low, stable contact resistance across the lifecycle. 5 A per circuit is the headline current rating; phosphor bronze handles the temperature rise without the contact spring relaxing. At 110 V rating, individual circuits carry 5 A in a board-to-board power rail or motor drive leg. Operating temperature spans -65°C to 130°C — wide enough for automotive under-hood zones and industrial process equipment, not just climate-controlled lab benches. UL94 V-0 thermoplastic housing will not support combustion and self-extinguishes, which matters in enclosed equipment where adjacent components could fail hot.
Sourcing posture
The BERGSTIK® 75844 series carries an Active lifecycle status — specified to order against BOM quantity on an RFQ. No official successor or cross-reference part number appears in the available record for this specific 10-position member, so the BERGSTIK® family parametric table is the primary path to a same-series alternative if the position count needs to change.
