AT17F080-30BJC Equivalent & Substitute Parts

Part Overview

The AT17F080-30BJC is a Flash memory integrated circuit manufactured by Microchip Technology, classified as a programmable memory device with 8Mb capacity. This component is designated as obsolete, which necessitates identification of equivalent or substitute parts for ongoing system support and new design implementations. The part operates within a supply voltage range of 2.97V to 3.63V and is housed in a 44-LCC (J-Lead) package configuration suitable for surface mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT17F080-30BJC is determined by the following critical parameters: identical memory type (FLASH), matching memory capacity (8Mb), compatible voltage supply range (2.97V ~ 3.63V), and manufacturer alignment (Microchip Technology). The AT17F080-30JU qualifies as a direct substitute based on these core electrical specifications. However, the substitute part exhibits differences in package configuration, operating temperature range, product status, and compliance certifications that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The AT17F080-30JU serves as the direct electrical substitute for the AT17F080-30BJC, maintaining identical memory capacity, type, and supply voltage specifications. The substitute part offers extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), supporting applications requiring broader thermal performance. The AT17F080-30JU holds active product status and achieves ROHS3 compliance, whereas the main part is obsolete and non-compliant with current RoHS standards.

Package configuration differs between the two parts: the main part uses a 44-LCC package while the substitute employs a 20-LCC package. This dimensional difference necessitates PCB layout modification and may impact pin count availability for system integration. The substitute part exhibits higher moisture sensitivity (MSL 3 versus MSL 2), requiring stricter handling protocols during storage and assembly.

Selection of the AT17F080-30JU is appropriate for new designs and systems where RoHS compliance is mandated. For legacy system maintenance where the original 44-LCC package configuration is required, alternative sourcing strategies or custom solutions may be necessary.

Frequently Asked Questions (FAQ)

Q: Can the AT17F080-30JU directly replace the AT17F080-30BJC without circuit modification?

A: Electrical substitution is valid based on matching memory type, capacity, and supply voltage. However, the package change from 44-LCC to 20-LCC requires PCB redesign and cannot be implemented as a direct pin-for-pin replacement.

Q: What is the significance of the different operating temperature ranges?

A: The main part operates from 0°C to 70°C, while the substitute operates from -40°C to 85°C. The substitute supports extended temperature applications. If the original system operates exclusively within 0°C to 70°C, both parts are functionally equivalent within that range.

Q: Why is RoHS compliance important for this substitution?

A: The AT17F080-30BJC is RoHS non-compliant, while the AT17F080-30JU achieves ROHS3 compliance. Current manufacturing and procurement standards increasingly require RoHS-compliant components. The substitute part aligns with modern regulatory requirements.

Q: What does the different Moisture Sensitivity Level (MSL) mean?

A: MSL 2 (main part) allows one year of storage under controlled conditions, while MSL 3 (substitute) allows 168 hours. The substitute requires more stringent moisture control during storage and assembly processes.

Q: Are there any other AT17F080 variants available?

A: Based on the provided data, the AT17F080-30JU is the documented substitute. Both parts share the AT17F080 base product number, indicating they are part of the same memory family with different package and specification variants.
