Engineering Selection Recommendations
The AT17F040-30CU is the direct substitute for the AT17F040-30CC. Selection between these parts should be based on the following factors:
Product Status: The AT17F040-30CC is obsolete, while the AT17F040-30CU maintains active product status with confirmed inventory availability (1193 pcs in stock versus 981 pcs for the main part). Active status ensures continued supply chain access and manufacturing support.
Compliance Posture: The AT17F040-30CU achieves ROHS3 compliance, whereas the AT17F040-30CC is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies compliance mandates.
Operating Temperature Range: The AT17F040-30CU supports an extended operating temperature range of -40°C to 85°C compared to the main part's 0°C to 70°C specification. This expanded range accommodates broader environmental conditions without functional degradation.
Electrical and Physical Compatibility: Both parts share identical supply voltage specifications (2.97V ~ 3.63V), memory capacity (4Mb), package configuration (8-TDFN), and mounting type (Surface Mount), ensuring direct functional interchangeability at the circuit board level.
Frequently Asked Questions (FAQ)
Q: Can AT17F040-30CU replace AT17F040-30CC in existing designs?
A: Yes. Both parts are electrically and physically compatible. They share identical supply voltage ranges, memory capacity, package type, and pin configuration. The substitute part operates across a wider temperature range and maintains the same MSL rating.
Q: What is the primary difference between these two parts?
A: The AT17F040-30CU has an extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), achieves ROHS3 compliance (versus RoHS non-compliant), and maintains active product status with higher inventory availability.
Q: Are there packaging differences between AT17F040-30CC and AT17F040-30CU?
A: No. Both parts use identical 8-TDFN packaging (8-LAP 6x6 supplier device package) with surface mount mounting type. Physical dimensions and pin layouts are identical.
Q: Does the AT17F040-30CU meet RoHS requirements?
A: Yes. The AT17F040-30CU is ROHS3 compliant, making it suitable for applications with RoHS regulatory requirements. The original AT17F040-30CC is RoHS non-compliant.
Q: What is the moisture sensitivity level for both parts?
A: Both the AT17F040-30CC and AT17F040-30CU have an MSL rating of 3 (168 Hours), indicating identical moisture handling and storage requirements.
Q: Is the AT17F040-30CU available for immediate use?
A: Yes. The AT17F040-30CU maintains active product status with 1193 pcs in stock, ensuring availability for current production and procurement needs.
