It carries 76 positions laid out as 38 per port, the standard pinout for QSFP and QSFP28 modules. The press-fit termination means the compliant pins cold-deform into the PCB plated through-holes during assembly, eliminating the solder step and making rework straightforward.
Why the Press-Fit and Shielding Matter for Signal Integrity
At the data rates ZQSFP+ handles — 25 Gbps per lane and above — every discontinuity in the signal path costs you eye height. The press-fit pin gives a gas-tight mechanical connection without the thermal stress of reflow, and the EMI shielding integrated into the cage keeps crosstalk between adjacent ports and radiated emissions from the board under control. The light pipe routes port-status indication to the front bezel without needing separate board-level LEDs, which simplifies the PCB layout and reduces the component count on the line card.
If your application calls for frequent module swaps in a lab or test environment, this plating grade will hold up. The tin-on-solder-tail interface (typical for press-fit pins) is a separate surface; the gold is only on the contact beam that wipes the module pad.
Packaging and Sourcing
The 2227669-3 ships in tray packaging, which is the standard for press-fit connectors that need to be kept aligned for automated placement. Lifecycle status is Active — the part is a current catalog item from TE, not a phase-out or last-time-buy situation.
