Are 10CX105YF672I6G and 10CX105YF672I6GSP the same device?

Are **10CX105YF672I6G and 10CX105YF672I6GSP the same device?**

**Yes, they are essentially the same device, but with subtle differences.** Both are **Intel (formerly Altera) Arria 10 GX** series FPGAs, specifically the **10CX105** (same density, approximately 105K logic cells), packaged in a **672-ball FineLine BGA** (YF672), with a **speed class** of **I6** (industrial grade, -40°C to 100°C), and the G indicating RoHS compliance.

**The meaning of the "SP" suffix (based on Intel's official community and product support information):**

"SP" is a **special suffix** added by Intel for certain devices. - This indicates that the batch of devices has undergone **additional qualification tests** or **silicon fix for an issue**.

- These modifications are typically to address specific issues (such as reliability, timing, power consumption, or edge cases in specific applications) or to meet additional customer/certification requirements.

- **Functionality, specifications, pin layout, and performance are completely identical** (pin-to-pin and drop-in compatible), and will not affect normal design use.

- The "SP" version is typically a **production-optimized or patched version**, considered an equivalent part within the same device family, and often appears in the supply chain or specific batches.

**Summary Comparison**:

**10CX105YF672I6G**: Standard production version (no special suffix).

**10CX105YF672I6GSP**: Standard version + additional qualification/patch batch (SP stands for Special Processing or Silicon Patch). - **Interchangeability:** **Absolutely**, direct replacement is risk-free (Intel community confirms that similar suffixes like SP indicate the same device, requiring only additional testing or repair).

**Recommendation:**

- If you see the SP version when purchasing or replacing, you can use it with confidence (it's usually more reliable because it has undergone additional verification).

- Verification method: Refer to the Intel Arria 10 device datasheet or the ARK website (search for 10CX105YF672I6G), or contact Intel support/distributors (such as DigiKey, Mouser) to verify the batch.

- If it's for a production design, prioritize the version with SP (indicating optimization), but there is no difference in specifications between the two.

If you have specific application scenarios (such as high-speed transceivers, power consumption requirements), I can help you compare them further!
