Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17F080-30CI is determined by strict equivalence across the following critical parameters:

• Memory type classification (FLASH)
• Memory capacity (8Mb)
• Supply voltage range (2.97V ~ 3.63V)
• Operating temperature range (-40°C ~ 85°C)
• Physical package format (8-TDFN / 8-LAP 6x6)
• Mounting technology (Surface Mount)
• Moisture sensitivity rating (MSL 3)

The AT17F080-30CU meets all these criteria and is identified as a direct substitute. The primary distinction between these parts is product status and packaging format, with the substitute part remaining in active production status.

Parameter Comparison

Engineering Selection Recommendations

The AT17F080-30CU is the direct equivalent substitute for the AT17F080-30CI. Selection of the substitute part is supported by:

• Identical electrical specifications across all operating parameters
• Identical physical package and pinout configuration
• Active product status ensuring continued availability and supply chain reliability
• ROHS3 compliance of the substitute part, providing regulatory advantage over the non-compliant original part
• Equivalent moisture sensitivity classification maintaining assembly process compatibility

The transition from AT17F080-30CI to AT17F080-30CU requires no circuit redesign or layout modification.

Frequently Asked Questions (FAQ)

Q: Can AT17F080-30CU be used as a direct replacement for AT17F080-30CI in existing designs?

A: Yes. Both parts share identical electrical specifications, package geometry, and pinout configuration. No circuit or PCB layout changes are required.

Q: What is the primary reason for substitution?

A: The AT17F080-30CI is obsolete. The AT17F080-30CU remains in active production, ensuring supply availability and long-term component sourcing.

Q: Are there compliance differences between these parts?

A: Yes. The AT17F080-30CU is ROHS3 compliant, while the AT17F080-30CI is RoHS non-compliant. This provides regulatory and environmental compliance advantages with the substitute part.

Q: Do the parts have identical moisture sensitivity requirements?

A: Yes. Both parts are classified as MSL 3 (168 Hours), requiring identical handling and storage protocols during assembly and manufacturing.

Q: Is the 8-TDFN package format identical between both parts?

A: Yes. Both parts use the 8-TDFN package with 8-LAP (6x6) supplier device package specification, ensuring mechanical and electrical compatibility.
