Board-to-Board Breakaway Header, 10 Positions
The Amphenol 93690-404-10LF is a 10-position, dual-row unshrouded breakaway header from the BERGSTIK series. It sits on the standard 0.100" (2.54mm) pitch — the same grid as legacy perfboard and common 0.1"-center prototyping layouts — with a matching 0.100" row spacing. All 10 positions are loaded, so the BOM line matches the circuit count directly; no partial-population variant to track. Rated 5A per contact at 110V, the tin-plated contacts carry enough current for signal-level power distribution on a PCB — think logic-level supply rails, sensor inputs, or low-current actuator lines. The 120.0µin (3.05µm) tin plating on both mating and post surfaces is thick enough for occasional mating cycles in a permanent-install context, though gold-plated siblings in the BERGSTIK line would serve higher-cycle or corrosive-environment duty better. Termination is through-hole with a press-fit option — the press-fit tail allows solderless assembly into plated-through holes, which is useful for backplane builds or any board where rework access matters. The housing is molded from UL94 V-0 thermoplastic, so the header meets the flame-rating requirement for equipment inside an enclosure.
Mating and Orientation
This is an unshrouded male pin header with a push-pull fastening type — no locking ramp or polarization key on the header itself. The mating receptacle must provide its own alignment and retention; standard BERGSTIK socket housings or IDC receptacles on the same 0.100" pitch are the natural match. The overall contact length of 0.872" (22.15mm) splits into a 0.583" (14.81mm) mating section and a 0.187" (4.75mm) solder tail — the tail length suits standard 1.6mm PCBs. The header mounts vertically through-hole, so the pin axis is perpendicular to the board plane. Board-to-board or board-to-cable stacking height is set by the mating receptacle's insulation height — the header's own insulation height is 0.100" (2.54mm) above the board surface.
Sourcing and Lifecycle
The 93690-404-10LF carries an Active lifecycle status from Amphenol — full production, no end-of-life notice on record. It is RoHS compliant. No official replacement or cross-reference is listed — the BERGSTIK series is broad, and this exact 10-position, tin-plated, press-fit variant has no direct factory successor.
