Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT17F080-30TQC is determined by the following critical parameters:

• Memory type: FLASH
• Memory capacity: 8Mb
• Supply voltage range: 2.97V ~ 3.63V
• Base product number: AT17F080
• Mounting type: Surface Mount

The identified substitute, AT17F080-30JU, shares the same base product number, memory type, memory capacity, and supply voltage specifications. However, this substitute employs a different package configuration (20-PLCC versus 44-TQFP), which requires PCB layout and footprint redesign. The substitute also features an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C) and improved RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The AT17F080-30JU is the designated manufacturer-recommended substitute for the obsolete AT17F080-30TQC. This substitute maintains electrical compatibility through identical memory capacity, supply voltage specifications, and FLASH memory type. The substitute is currently in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

• The substitute operates across an extended temperature range, providing broader environmental tolerance than the original part.
• The substitute achieves ROHS3 compliance, whereas the original part is RoHS non-compliant.
• Package redesign is mandatory due to the transition from 44-TQFP to 20-PLCC configuration, requiring PCB layout modification and re-qualification.
• Both parts maintain identical moisture sensitivity classification and supply voltage parameters.

Frequently Asked Questions (FAQ)

Q: Can AT17F080-30JU be used as a direct pin-for-pin replacement for AT17F080-30TQC?

A: No. While both parts share identical electrical specifications for memory capacity and supply voltage, they employ different package configurations (44-TQFP versus 20-PLCC). PCB layout redesign and footprint modification are required.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by memory type (FLASH), memory capacity (8Mb), and supply voltage range (2.97V ~ 3.63V). Both the main part and substitute meet these criteria.

Q: Does the substitute support the same operating temperature range?

A: No. The AT17F080-30JU operates from -40°C to 85°C, which exceeds the original part's range of 0°C to 70°C. This extended range provides additional environmental flexibility.

Q: What is the significance of the RoHS compliance difference?

A: The substitute achieves ROHS3 compliance, while the original part is RoHS non-compliant. This difference may impact regulatory requirements and supply chain acceptance depending on application and regional standards.

Q: Are there any inventory considerations for this substitution?

A: The original AT17F080-30TQC is listed as obsolete. The substitute AT17F080-30JU is in active production with confirmed inventory availability, supporting long-term design continuity.
