44-Position Board-to-Board Receptacle for Dense Mezzanine Stacks
The 55510-344TRLF: This is a 44-position, 2-row receptacle from the Minitek® 2.00mm series, designed for board-to-board mezzanine connections.
Termination is solder-only, surface mount, with the part supplied on Tape & Reel and a Pick and Place feature — the vacuum pick area is flat and centred, compatible with standard nozzle sizes. The black insulation colour aids optical alignment during placement.
No official replacement or cross-reference exists; the 55510 base number covers the series. The Tape & Reel packaging suits volume SMT assembly. For prototype or low-volume needs, request cut tape or tube availability at quote time.
Mating Half and Application Fit
This receptacle mates with a 2-row, 2.00 mm pitch pin header from the same Minitek® 2.00mm series — typically the 55510 header family. Confirm the header's pin length and stack height match your board-to-board spacing; the 4.50 mm insulation height sets the minimum mated stack. Applications include general-purpose, industrial, and medical equipment where a reliable, mid-density board-to-board interconnect is needed. The 2 A per contact rating suits signal and low-power distribution.
