Product details

Board-edge ZQSFP+ receptacle for 28 Gbps lanes

The TE Connectivity 1551920-1 is a 38-position ZQSFP+ receptacle in a surface-mount, right-angle package. It sits at the board edge and accepts the standard QSFP+ / ZQSFP+ plug module — the 38 contacts map to the four high-speed differential lanes plus sideband signals defined by the QSFP MSA.

Active production — no obsolescence risk

There is no last-time-buy or end-of-life notice on this part number.

ZQSFP+ vs ZQSFP — what changed

The ZQSFP+ designation on this receptacle indicates it is built to the enhanced specification that supports higher data rates per lane compared to the original ZQSFP.

Termination is solder — surface-mount, right-angle — so the receptacle is reflow-soldered to the PCB in a standard SMT line. The Tape & Reel packaging (also available in Cut Tape) feeds into a pick-and-place machine for volume assembly.

Frequently asked questions

Is 1551920-1 a direct replacement for older ZQSFP connectors?

The 38-position pinout is identical, so it is a mechanical drop-in. The ZQSFP+ designation means the contact and footprint are tuned for higher data rates — it will work in a legacy ZQSFP layout but the signal-integrity benefit only matters if the PCB trace design supports the higher speed.
