The TE Connectivity 2227581-1 is a SAS Mini HD receptacle in a 1x2 connector style, carrying 72 positions arranged as 36 per row. This is the board-side half of a high-speed internal interconnect used in storage servers, RAID controllers, and enterprise backplanes where SAS 3.0 or Mini HD signal routing is required. The press-fit termination eliminates solder, which keeps the through-hole joints reliable in high-vibration environments and simplifies rework on multi-layer backplanes.
Board Layout and Assembly Fit
The 36 x 2 position grid defines the PCB footprint — the hole pattern and keep-out zone must match the TE recommended layout for the Mini HD series. Press-fit tails require a controlled plated-through-hole diameter; the board shop needs the TE application spec for the hole size and the press-in tooling anvil height. Tray packaging is standard for press-fit parts — the connector ships in a rigid tray that protects the compliant pins during handling and feeds into automated placement or manual insertion fixtures.
