The Amphenol FCI 10162581-3134111LF is an 11-position receptacle from the Conan™ MezzSelect™ series, built for board-to-board mezzanine stacking at a 0.039" (1.00mm) pitch. This receptacle is surface-mount only, with board guide features and pick-and-place pads that let it run through a standard SMT line without a secondary hand-place step. Typical use is in compact mezzanine stacks where the 1.00mm pitch saves board real estate compared to a 1.27mm or 2.54mm pitch solution, and the multiple stacking heights (4.15mm, 4.5mm, 5mm, 6mm, 7mm) give the layout engineer one receptacle to qualify across several board-spacing variants.
One receptacle, five mated stacking heights — that is the practical takeaway from the 4.15mm, 4.5mm, 5mm, 6mm, and 7mm options listed for this part. The same 10162581-3134111LF footprint on the PCB mates with a Conan header in any of those heights, so a single board design can serve multiple enclosure depths by swapping only the header. For the contract manufacturer, that means one reeled part number to inventory and one placement program to validate, while the stack height is set by the header variant on the other board.
Position Count Variants in the Conan Series
The 11-position 10162581-3134111LF sits between the 9-position 10162581-3134109LF and the 15-position 10162581-3134115LF, all at the same 0.039" (1.00mm) pitch and 0.129" (3.28mm) height above board. The 21-position 10162581-3134121LF extends the same footprint length. No other spec changes between the variants, which simplifies AVL management: one reel part number per position count, same placement parameters.
