What Is the 2227582-1 and Where Was It Used?
The TE Connectivity 2227582-1 is a SAS Mini HD receptacle in a 1x4 stacked configuration — four SAS ports in a single housing, each carrying 36 positions for a total of 144 circuits. This connector was designed for internal high-speed storage backplane interconnects in enterprise servers, storage arrays, and RAID controllers, where SAS (Serial Attached SCSI) signalling carries data at 3, 6, or 12 Gb/s per lane. The press-fit termination eliminates the need for wave soldering, making it suitable for high-reliability backplane assemblies where rework and field replacement matter.
Key Termination and Mounting Details
Press-fit termination means the compliant-eyelet pins are pressed into plated through-holes in the PCB — no solder joint, no heat stress on the backplane. The through-hole mounting provides mechanical retention during the press operation and under vibration in the installed system.
No direct drop-in replacement is listed in the evidence. Buyers should expect to work with surplus or broker channels for this specific order code.
