Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT45DB041E-SHNHT-B are qualified based on the following critical parameters that determine functional interchangeability:

• Memory Capacity & Organization: 4Mbit capacity with 264 Bytes × 2048 pages organization
• Interface Protocol: SPI serial interface at 85 MHz clock frequency
• Electrical Characteristics: Supply voltage range 1.65V – 3.6V and write cycle timing (8µs word, 3ms page)
• Physical Package: 8-SOIC surface mount package with 0.154" (3.90mm) width
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

Substitute parts maintain identical electrical and memory specifications. Variations in packaging format (Tube vs. Tape & Reel) and operating temperature range do not affect functional compatibility in applications designed for the base AT45DB041 series.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and functional compatibility with the AT45DB041E-SHNHT-B. Selection among equivalent parts should be based on:

Packaging Format Considerations: The main part (AT45DB041E-SHNHT-B) is supplied in Tube packaging, while AT45DB041E-SSHNHA-T and AT45DB041E-SSHNHC-T are supplied in Tape & Reel format. AT45DB041E-SSHN-B is supplied in Tube format. Packaging selection depends on assembly process requirements and volume specifications.

Operating Temperature Range: The main part supports -40°C to 125°C operation. Substitute parts AT45DB041E-SSHNHA-T, AT45DB041E-SSHNHC-T, and AT45DB041E-SSHN-B support -40°C to 85°C operation. Applications requiring operation above 85°C must use the main part AT45DB041E-SHNHT-B.

Manufacturer Source: Renesas Electronics Corporation manufactures AT45DB041E-SHNHT-B, AT45DB041E-SSHNHA-T, and AT45DB041E-SSHNHC-T. Adesto Technologies manufactures AT45DB041E-SSHN-B. All parts maintain ROHS3 compliance and MSL Level 1 rating.

Inventory Availability: Current stock levels vary across part numbers and packaging formats, which may influence procurement decisions for production schedules.

Frequently Asked Questions (FAQ)

Q: Can AT45DB041E-SSHNHA-T replace AT45DB041E-SHNHT-B in all applications?

A: AT45DB041E-SSHNHA-T is electrically and functionally equivalent for applications operating within -40°C to 85°C temperature range. Applications requiring operation above 85°C must use AT45DB041E-SHNHT-B, which supports up to 125°C. The primary difference is packaging format (Tape & Reel vs. Tube) and operating temperature specification.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging supplies individual components in a plastic tube, suitable for lower-volume assembly or manual handling. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly equipment. Both formats contain identical components with identical electrical specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—AT45DB041E-SSHNHA-T, AT45DB041E-SSHNHC-T, and AT45DB041E-SSHN-B—are ROHS3 compliant with MSL Level 1 rating, matching the compliance profile of the main part AT45DB041E-SHNHT-B.

Q: What determines if a part is a valid substitute for AT45DB041E-SHNHT-B?

A: Valid substitutes must match the following specifications: 4Mbit FLASH memory capacity, 264 Bytes × 2048 pages organization, SPI interface at 85 MHz, supply voltage 1.65V – 3.6V, 8-SOIC package, and ROHS3 compliance. Operating temperature range and packaging format may vary without affecting functional interchangeability in applications designed within the substitute part's temperature specification.

Q: Can I use AT45DB041E-SSHN-B (Adesto Technologies) as a direct replacement?

A: AT45DB041E-SSHN-B is functionally equivalent to AT45DB041E-SHNHT-B for applications operating within -40°C to 85°C. Both are supplied in Tube packaging. The primary difference is manufacturer source (Adesto Technologies vs. Renesas Electronics). All electrical specifications, memory organization, interface protocol, and compliance certifications are identical.
