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.","metaTitle":"TE 1551920-1 ZQSFP+ Receptacle, 38 Pos, SMT Right Angle","metaDescription":"TE Connectivity 1551920-1 ZQSFP+ receptacle, 38 positions, SMT right-angle, gold 15.0µin contacts.

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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1551920-1","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/1551920-1 when reusing this data.
