Board-to-Board Mating Pair and Stack Height Finder
Find the mating plug / receptacle for a board-to-board part and its stack height, or find pairs for a required board gap.
Find the mating part
Type an LT code or ECT number, or pick from the list.
Find pairs by requirement
A pair is only listed when the plug and the receptacle in the same family state the same pitch, number of positions and height, belong to the same manufacturer series, and there is exactly one such combination. Anything less certain is left out. The height H is the value printed for both parts of the pair in the ECTCONN manual’s spec text; for these board-to-board families it is the mated stacking height. Confirm tolerances, floating range and PCB layout on the datasheet before design-in. Floating connectors list different heights for plug and receptacle and are therefore not paired automatically.
For preliminary assessment only — the final decision must follow the manufacturer’s datasheet and the applicable NEC / IEC / UL standards. Results are calculated from the standard formulas stated on this page and are for design estimates only. They are not a rating of any specific part — always confirm current, voltage, temperature and environment limits against the manufacturer’s datasheet for the part you intend to use.
