Substitute Part Grouping Explanation

Substitution eligibility for the AT17F040-30CI is determined by strict equivalence across the following critical parameters:

• Memory Size: 4Mb (exact match required)
• Programmable Type: FLASH (exact match required)
• Voltage - Supply: 2.97V ~ 3.63V (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)
• Package / Case: 8-TDFN (exact match required)
• Supplier Device Package: 8-LAP (6x6) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Moisture Sensitivity Level: 3 (168 Hours) (exact match required)

The AT17F040-30CU qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The AT17F040-30CU is the direct substitute for the AT17F040-30CI. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in all applications.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The AT17F040-30CI is obsolete, while the AT17F040-30CU maintains active product status with ROHS3 compliance. For new designs and ongoing production, the AT17F040-30CU is the appropriate selection. For legacy system maintenance where the original AT17F040-30CI specification is required, the AT17F040-30CU provides full electrical and mechanical equivalence.

Frequently Asked Questions (FAQ)

Q: Can the AT17F040-30CU replace the AT17F040-30CI in existing designs?

A: Yes. The AT17F040-30CU is electrically and mechanically equivalent to the AT17F040-30CI across all specified parameters, including memory size, voltage supply range, operating temperature range, package type, and pin configuration.

Q: What is the difference between AT17F040-30CI and AT17F040-30CU?

A: The primary differences are product status and regulatory compliance. The AT17F040-30CI is obsolete and RoHS non-compliant, while the AT17F040-30CU is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The AT17F040-30CI is supplied in standard packaging, while the AT17F040-30CU is supplied in tube packaging. Both use the same 8-LAP (6x6) device package and 8-TDFN case format. This packaging difference does not affect electrical performance or mechanical compatibility.

Q: Is the AT17F040-30CU suitable for applications requiring RoHS compliance?

A: Yes. The AT17F040-30CU is ROHS3 compliant, making it suitable for applications with RoHS requirements. The AT17F040-30CI is RoHS non-compliant.

Q: What is the moisture sensitivity level for these parts?

A: Both the AT17F040-30CI and AT17F040-30CU have a Moisture Sensitivity Level (MSL) of 3 with a 168-hour floor life rating. Standard moisture control procedures must be followed during storage and handling.
