Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT17F080-30JI is determined by strict equivalence across the following parameters: memory type (FLASH), memory capacity (8Mb), voltage supply specifications (2.97V ~ 3.63V), operating temperature range (-40°C ~ 85°C), package configuration (20-LCC J-Lead), and mounting methodology (Surface Mount). The AT17F080-30JU meets all these criteria and is classified as a direct substitute. Both parts share the same base product number (AT17F080) and are manufactured by Microchip Technology, confirming functional and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AT17F080-30JU is the direct equivalent substitute for the AT17F080-30JI. Both components are electrically and mechanically identical across all functional parameters. The primary distinction is product lifecycle status: the AT17F080-30JI is obsolete while the AT17F080-30JU maintains active production status. Additionally, the AT17F080-30JU achieves ROHS3 compliance, whereas the AT17F080-30JI is non-compliant. For new designs and ongoing system support, the AT17F080-30JU is the appropriate selection. The difference in Moisture Sensitivity Level (MSL 2 versus MSL 3) reflects standard handling and storage protocol variations between the two part revisions and does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Are AT17F080-30JI and AT17F080-30JU pin-for-pin compatible? A: Yes. Both components utilize the 20-LCC (J-Lead) package configuration with identical pinout and electrical characteristics. Direct substitution is possible without circuit modification.

Q: What is the significance of the product status difference (Obsolete vs. Active)? A: The AT17F080-30JI is no longer manufactured. The AT17F080-30JU is the current production equivalent. For new designs and long-term availability, AT17F080-30JU is the recommended selection.

Q: Does the RoHS compliance difference affect electrical performance? A: No. RoHS compliance pertains to material composition and environmental regulations, not electrical function. Both parts operate identically within specified parameters.

Q: What does the Moisture Sensitivity Level (MSL) difference indicate? A: MSL ratings specify maximum storage duration at specified humidity levels before component degradation. MSL 2 allows 1 year storage; MSL 3 allows 168 hours. This affects handling and storage procedures but not functional performance.

Q: Can AT17F080-30JI be used in new production designs? A: No. As an obsolete component, AT17F080-30JI is not recommended for new designs. AT17F080-30JU should be specified for all new applications.
