Press-Fit zSFP+ Receptacle with Integrated Cage — 912 Positions
The TE Connectivity 2227838-7 is a zSFP+ receptacle with a ganged (2x12) cage, carrying 912 positions arranged as 38x12. Press-fit termination means the connector presses into plated through-holes without solder — standard for backplane assemblies where rework access and high-reliability connections are required. The cage is EMI shielded, a built-in feature that contains radiated emissions from the high-speed signal paths inside the zSFP+ modules. This avoids the need for a separate shield can or gasket at the panel opening.
The 912-position count (38x12) is the sum of all signal and ground contacts across the 24 module ports (2 rows of 12). Each zSFP+ module position uses a 38-contact footprint. The press-fit tails require a plated through-hole per contact, so the PCB must have 912 drilled and plated holes within the footprint of the ganged cage. Compared to the 2227838-6, which is the same ganged 2x12 cage and 912-position count, the -7 variant may differ in plating finish or tail length — confirm the specific tail length against the board thickness before committing the BOM line.
