Substitute Part Grouping Explanation

Substitution of the EP3SL70F780C3 is determined by strict equivalence across the following critical parameters:

• Series and Base Product Number: Both parts belong to the Stratix® III L series with base product number EP3SL70
• Logic Density: Identical logic element count (67,500) and RAM capacity (2,699,264 bits)
• I/O Configuration: Both feature 488 I/O pins
• Electrical Specifications: Matching supply voltage range (0.86V ~ 1.15V) and operating temperature range (0°C ~ 85°C)
• Package Specification: Identical 780-FBGA (29x29) package geometry and 780-BBGA, FCBGA case designation
• Environmental Compliance: Both are RoHS Compliant with MSL rating of 3 (168 Hours)

The EP3SL70F780C3G differs from the main part only in packaging format (Tray versus unspecified) and product status (Active versus Obsolete), with no functional or electrical differences.

Parameter Comparison

Engineering Selection Recommendations

The EP3SL70F780C3G is a direct functional equivalent to the EP3SL70F780C3. Selection between these parts should be based on the following criteria:

For New Designs: The EP3SL70F780C3G is the appropriate choice due to its Active product status, ensuring continued manufacturer support, availability, and compliance documentation.

For Legacy System Maintenance: The EP3SL70F780C3 remains functionally equivalent and may be selected if existing inventory is available and design qualification has been completed.

Compliance Considerations: Both parts maintain RoHS Compliance and identical MSL ratings, satisfying environmental and reliability requirements for embedded applications.

Frequently Asked Questions (FAQ)

Q: Can EP3SL70F780C3G be used as a direct replacement for EP3SL70F780C3?

A: Yes. Both parts are electrically and functionally identical across all specified parameters, including logic element count, I/O configuration, supply voltage, operating temperature range, and package geometry. The only difference is product status and packaging format.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Product status indicates manufacturer support lifecycle. The Active status of EP3SL70F780C3G ensures ongoing availability, technical support, and compliance documentation. The Obsolete status of EP3SL70F780C3 indicates end-of-life status, though existing inventory may remain available.

Q: Are there any package or thermal considerations when substituting these parts?

A: No. Both parts use the identical 780-FBGA (29x29) package with matching thermal and mechanical specifications. PCB layout, thermal management, and mounting procedures remain unchanged.

Q: Does the packaging format (Tray) affect electrical performance?

A: No. Packaging format affects only handling, storage, and logistics. Electrical and functional performance is identical regardless of whether the part is supplied in Tray or other packaging formats.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of 0°C to 85°C (TJ), with matching MSL ratings of 3 (168 Hours).
