Substitute Part Grouping Explanation

Substitute parts for the AT45DB081E-SHNHA-T are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

  • Memory capacity: 8Mbit
  • Memory interface protocol: SPI
  • Operating frequency: 85 MHz
  • Supply voltage range: 1.7V ~ 3.6V
  • Operating temperature range: -40°C ~ 85°C
  • Package type: 8-SOIC with 5.30mm width
  • Surface mount configuration
  • RoHS3 compliance
  • Moisture sensitivity level: 1 (Unlimited)

The identified substitutes differ only in packaging format (Tape & Reel, Tube, or Cut Tape & Digi-Reel), which does not affect electrical performance or mechanical compatibility in the end application.

Engineering Selection Recommendations

All three parts—AT45DB081E-SHNHA-T, AT45DB081E-SHN-B, and AT45DB081E-SHN-T—are manufactured by Renesas Electronics Corporation and maintain active product status. Each part carries ROHS3 compliance and identical electrical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

  • AT45DB081E-SHNHA-T: Tape & Reel packaging, 976 units in stock
  • AT45DB081E-SHN-B: Tube packaging, 3883 units in stock
  • AT45DB081E-SHN-T: Cut Tape & Digi-Reel packaging, 24121 units in stock

All parts are suitable for direct substitution in applications requiring 8Mbit SPI FLASH memory with 85 MHz operation and -40°C to 85°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can AT45DB081E-SHN-B replace AT45DB081E-SHNHA-T in production?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: AT45DB081E-SHNHA-T uses Tape & Reel while AT45DB081E-SHN-B uses Tube. PCB assembly compatibility is maintained across both formats.

Q: What is the difference between Tape & Reel, Tube, and Cut Tape & Digi-Reel packaging?

A: These are supply chain packaging formats that do not affect the component itself. Tape & Reel is used for automated pick-and-place assembly. Tube packaging is used for manual handling or lower-volume applications. Cut Tape & Digi-Reel is a flexible format suitable for both automated and manual processes. All three formats contain the same 8-SOIC component.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. AT45DB081E-SHNHA-T, AT45DB081E-SHN-B, and AT45DB081E-SHN-T are all ROHS3 compliant with unlimited moisture sensitivity level rating.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. All three parts have identical electrical specifications, pin configurations, and operating parameters. No circuit modifications are required when substituting between these part numbers.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -40°C to 85°C (TC), making them suitable for industrial and commercial temperature environments.
