AT17F080A-30QC Equivalent & Substitute Parts

Part Overview

The AT17F080A-30QC is a Flash memory integrated circuit manufactured by Microchip Technology, classified as a configurable memory device with 8Mb capacity. This part is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design requirements and component procurement. The original part is supplied in 32-TQFP surface mount packaging with a tray packaging option.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17F080A-30QC is determined by the following critical parameters:

• Memory Type and Capacity: Both parts must be FLASH memory with 8Mb capacity
• Supply Voltage Compatibility: Operating voltage range must support the 2.97V ~ 3.63V specification
• Mounting Technology: Surface mount configuration is required
• Base Product Compatibility: Parts sharing the AT17F080A base product number maintain functional equivalence

The AT17F080A-30JU qualifies as a substitute based on matching memory type (FLASH), capacity (8Mb), supply voltage range (2.97V ~ 3.63V), and mounting type (Surface Mount). The primary difference is packaging format: the substitute uses 20-PLCC (J-Lead) instead of 32-TQFP, which requires PCB layout redesign but maintains electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AT17F080A-30JU is the qualified substitute for the obsolete AT17F080A-30QC based on electrical parameter equivalence. Selection considerations are:

• Product Status: The substitute is Active, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the main part
• Compliance: The substitute achieves ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements
• Thermal Performance: The substitute supports an extended operating temperature range (-40°C ~ 85°C) compared to the main part (0°C ~ 70°C), providing greater operational flexibility
• Moisture Handling: The substitute has improved moisture sensitivity (MSL 2, 1 Year) versus the main part (MSL 3, 168 Hours)
• Package Redesign Required: PCB layout modification is necessary due to package format change from 32-TQFP to 20-PLCC

Frequently Asked Questions (FAQ)

Q: Can the AT17F080A-30JU be used as a direct pin-for-pin replacement?

A: No. While electrically equivalent, the AT17F080A-30JU uses a different package format (20-PLCC versus 32-TQFP). PCB footprint redesign and layout modification are required.

Q: What are the key electrical compatibility factors?

A: The substitute maintains identical memory capacity (8Mb), programmable type (FLASH), and supply voltage range (2.97V ~ 3.63V). These parameters ensure functional equivalence in circuit operation.

Q: Why is the operating temperature range different?

A: The substitute supports -40°C ~ 85°C versus the original 0°C ~ 70°C. This extended range is a design improvement and does not prevent substitution; applications operating within the original temperature window remain fully compatible.

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

A: The main part is RoHS non-compliant while the substitute is ROHS3 compliant. For new designs or applications subject to RoHS regulations, the substitute is the appropriate choice.

Q: Are there inventory considerations?

A: Both parts are currently in stock. The main part (1099 Pcs) is available in Tray packaging, while the substitute (924 Pcs) is supplied in Tube packaging.
