Substitute Part Grouping Explanation

Substitute parts for the AT45DB041E-SSHNHC-T are qualified based on identical electrical and functional parameters: 4Mbit memory capacity, FLASH technology, SPI interface, 85 MHz clock frequency, 264 Bytes x 2048 pages organization, 8µs/3ms write cycle times, 1.65V–3.6V supply voltage range, -40°C to 85°C operating temperature, and 8-SOIC package footprint. The substitutes differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability, which do not affect functional or electrical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—AT45DB041E-SSHNHC-T, AT45DB041E-SSHN-T, and AT45DB041E-SSHNHA-T—are manufactured by Renesas Electronics Corporation and maintain active product status. Each part is ROHS3 compliant and carries MSL rating 1 (unlimited moisture sensitivity level), indicating equivalent reliability and environmental compliance. Selection between these parts is determined by packaging and supply chain requirements rather than functional or electrical differences. The AT45DB041E-SSHNHC-T and AT45DB041E-SSHNHA-T are supplied in Tape & Reel format suitable for automated assembly processes, while the AT45DB041E-SSHN-T is available in Cut Tape and Digi-Reel format for alternative distribution channels.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. All three parts share identical electrical specifications, memory capacity, interface protocol, clock frequency, voltage range, and operating temperature range. They are functionally equivalent in circuit applications.

Q: What is the difference between these substitute parts? A: The primary difference is packaging format. AT45DB041E-SSHNHC-T and AT45DB041E-SSHNHA-T are supplied in Tape & Reel (TR) format, while AT45DB041E-SSHN-T is supplied in Cut Tape (CT) and Digi-Reel format. The physical component and pin configuration remain identical.

Q: Can I use these parts interchangeably on the same PCB assembly? A: Yes. All parts use the same 8-SOIC package footprint (0.154", 3.90mm width) and surface mount configuration. PCB layout and solder pad design are identical across all three parts.

Q: Do packaging differences affect component performance? A: No. Packaging format affects only handling, storage, and supply chain logistics. Electrical performance, reliability, and functional characteristics are unaffected by the packaging format.

Q: Are all parts ROHS3 compliant? A: Yes. All three parts carry ROHS3 compliance certification and are suitable for applications requiring environmental compliance.

Q: What is the MSL rating and why does it matter? A: All parts carry MSL rating 1 (Unlimited), indicating unlimited shelf life without moisture bake-out requirements. This simplifies inventory management and reduces handling constraints.
