Substitute Part Grouping Explanation

Substitution eligibility for the 5SEE9F45C4N is determined by strict equivalence across the following critical parameters:

• Logic Architecture: Identical logic element count (840,000) and LAB/CLB configuration (317,000)
• I/O Configuration: Matching I/O pin count (840 pins)
• Memory Capacity: Equivalent total RAM bits (53,248,000)
• Electrical Specifications: Identical supply voltage range (0.82V ~ 0.88V) and operating temperature range (0°C ~ 85°C)
• Physical Package: Same package designation (1932-BBGA, FCBGA) and footprint (45x45mm FC)
• Compliance: RoHS compliance and MSL rating (3, 168 Hours)

The substitute part 5SEE9F45C4G meets all these criteria while differing only in packaging format (Tray vs. unspecified) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The 5SEE9F45C4G is a direct functional equivalent to the 5SEE9F45C4N. Both parts are RoHS compliant and share identical electrical, thermal, and mechanical specifications. The primary distinction is product status: the 5SEE9F45C4G maintains Active status with higher current inventory availability (1,091 pcs vs. 760 pcs), making it the preferred selection for new designs and ongoing procurement. The 5SEE9F45C4N remains suitable for legacy system maintenance where existing stock is available, though long-term sourcing should transition to the Active variant.

Frequently Asked Questions (FAQ)

Q: Can the 5SEE9F45C4G directly replace the 5SEE9F45C4N in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including logic element count, I/O configuration, supply voltage, operating temperature range, and package footprint. No design modifications are required.

Q: What is the difference between the two part numbers?

A: The primary difference is product status and packaging format. The 5SEE9F45C4G is Active with Tray packaging, while the 5SEE9F45C4N is Obsolete with unspecified packaging. All functional and electrical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5SEE9F45C4N and 5SEE9F45C4G are RoHS compliant with identical Moisture Sensitivity Level ratings (MSL 3, 168 Hours).

Q: What is the significance of the 1932-FBGA, FC (45x45) package designation?

A: This specifies a Fine-pitch Ball Grid Array package with 1932 balls in a 45mm × 45mm footprint. Both substitute parts use this identical package, ensuring PCB layout and assembly compatibility.

Q: Should new designs use the 5SEE9F45C4G instead of the 5SEE9F45C4N?

A: Yes. The 5SEE9F45C4G is the recommended selection for new designs due to its Active product status and superior availability. The 5SEE9F45C4N should be reserved for legacy system support where existing inventory exists.
