The useful distinction
Recognize it. Then verify it.
The SFF-TA-1002 2C connector variation is documented with 84 contacts and up to 26 differential data pairs. [C292A]
Source-scoped identification facts
Each value retains its exact example, role and measurement axis. Facts from different parts must not be combined into an invented component.

Recorded variant and source limits
- EDSFF, OCP, Gen-Z and other implementation contexts can use different logical assignments over related connector variations.
- Connector variation and pair capacity do not establish active lane count, protocol generation, power delivery, sideband wiring, host support or fabrication dimensions.

Specifications and limits
| Documented identification | SNIA REF-TA-1012 identifies the SFF-TA-1002 2C connector variation as an 84-contact connector with up to 26 differential pairs of data signals. [C292A] |
|---|---|
| Mechanical dimensions | No independently reviewed mechanical drawing in V50; do not use this page for fabrication, fit testing or tolerance work. |
| Engineering pinout | Source-checked engineering profile available; independent review pending. Open engineering profile → |
| Verified device list | Not included. Check exact device and accessory documentation. |
Use only the source-backed family, role or position count for identification. Resolve electrical ratings, protocol generation, lane wiring, signal assignment, cable construction and exact device support from the relevant equipment and component documentation.
Before you connect
What to check
- Identify the exact connector family and variant from the equipment or component documentation.
- Keep physical form, contact count, protocol, electrical rating and device support as separate facts.
- Do not force, rewire, adapt or install from this recognition record; resolve the remaining requirements first.
What is not established
This field note does not approve a connection, adapter, cable assembly, rewiring scheme, energized-work procedure or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
