Substitute Part Grouping Explanation

Substitution for the EP3SL70F484C4 is determined by strict equivalence across the following critical parameters:

• Logic Architecture: Identical number of logic elements (67,500) and LABs/CLBs (2,700)
• Memory Configuration: Matching total RAM bits (2,699,264)
• I/O Count: Equivalent number of I/O pins (296)
• Electrical Specifications: Identical supply voltage range (0.86V ~ 1.15V) and operating temperature range (0°C ~ 85°C)
• Physical Package: Same package type (484-BBGA, FCBGA 23x23) ensuring mechanical and thermal compatibility
• Compliance: RoHS compliance and MSL rating (3) maintained across all substitutes

The EP3SL70F484C4G qualifies as a direct substitute based on complete parameter alignment. The primary distinction is product status and packaging format, with the substitute part remaining in active production.

Parameter Comparison

Engineering Selection Recommendations

The EP3SL70F484C4G is the appropriate substitute for the EP3SL70F484C4 based on the following factors:

• Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete main part number.
• Functional Equivalence: All electrical, logical, and physical parameters are identical, guaranteeing pin-for-pin and functional compatibility in existing designs.
• Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings, supporting equivalent handling and storage requirements.
• Packaging Consideration: The substitute is supplied in tray format rather than tube format. This difference affects only logistics and handling procedures, not electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can EP3SL70F484C4G be used as a direct replacement for EP3SL70F484C4?

A: Yes. The substitute part is functionally and electrically identical. All logic elements, memory, I/O count, voltage specifications, and operating temperature ranges match exactly. The package type and physical dimensions are identical.

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

A: The primary differences are product status and packaging format. EP3SL70F484C4 is obsolete and supplied in tube packaging, while EP3SL70F484C4G is in active production and supplied in tray packaging. These differences do not affect electrical performance or board-level compatibility.

Q: Are there any handling or storage differences between these parts?

A: Both parts share identical Moisture Sensitivity Level (MSL 3, 168 hours) and RoHS compliance status. Handling and storage procedures are equivalent. The tray packaging of the substitute may offer improved protection during transport compared to tube packaging.

Q: Will the substitute part work in existing PCB designs?

A: Yes. The 484-FBGA (23x23) package dimensions, pin configuration, and electrical specifications are identical. No PCB redesign is required.

Q: Why is the main part number obsolete?

A: The EP3SL70F484C4 has reached end-of-life status. The EP3SL70F484C4G represents the active production equivalent, ensuring continued availability for system support and new designs.
