The TE Connectivity 2214574-3 is a QSFP+ receptacle with an integrated cage, configured as a ganged 1x4 assembly. It carries 152 positions arranged as 38 per port across four ports. This is the board-side interconnect for a 4-port QSFP+ module cage — the part that mounts to the PCB and receives the pluggable transceiver modules. The integrated light pipe routes the module's link-status LEDs to the faceplate, and the cage provides the EMI shielding required to keep the system within radiated-emission limits for 25 Gbps per-lane signaling.
Press-fit means the compliant pin tail is pressed into a plated through-hole — no solder, no reflow profile, no flux residue. The through-hole, right-angle mounting requires the PCB to have the correct hole diameter and finished-plating thickness for the press-fit zone, typically specified in the TE application drawing. The 152-position footprint is dense: four rows of 38 contacts per port, with the cage ground pins surrounding the signal array. The light pipe adds a secondary alignment feature on the faceplate side; the board keep-out zone must account for the pipe's exit path.
QSFP28 and 100G Compatibility
The 2214574-3 is a QSFP+ receptacle, which uses the same mechanical interface as QSFP28 and QSFP-DD modules. The cage and connector body are form-factor compatible with QSFP28 transceivers rated for 100G (4x25 Gbps) and QSFP+ modules rated for 40G (4x10 Gbps). The electrical performance of the receptacle itself — contact resistance, return loss, and crosstalk — must be verified against the module's link budget, but the mechanical fit is standard across the QSFP family. The press-fit termination and cage shielding are identical for both data rates; the limiting factor is the PCB trace design, not the connector.
Active lifecycle — no end-of-life notification or last-time-buy window. Tray packaging is standard for this cage assembly.
