Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT45DB021E-SSHNHC-T are qualified based on identical electrical performance parameters and mechanical compatibility. The substitution criteria are:

• Memory capacity: 2Mbit
• Interface protocol: SPI
• Operating frequency: 70 MHz
• Memory organization: 264 Bytes x 1024 pages
• Write cycle timing: 8µs (word) / 3ms (page)
• Supply voltage: 1.65V ~ 3.6V
• Temperature range: -40°C ~ 85°C
• Package type: 8-SOIC surface mount
• Compliance: ROHS3, REACH Unaffected

Variations in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) do not affect electrical or functional compatibility and are determined by supply chain and procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with Renesas Electronics Corporation and are fully compliant with ROHS3 and REACH regulations. Selection between AT45DB021E-SSHNHC-T, AT45DB021E-SSHN-T, and AT45DB021E-SSHNHA-T is determined by packaging format requirements and inventory availability rather than electrical performance differences.

AT45DB021E-SSHN-T offers the highest current inventory (24,098 pcs) and is available in Cut Tape & Digi-Reel format, suitable for automated pick-and-place assembly operations. AT45DB021E-SSHNHC-T and AT45DB021E-SSHNHA-T are supplied in Tape & Reel format with lower inventory levels (1,225 pcs and 1,110 pcs respectively), appropriate for high-volume production runs.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. AT45DB021E-SSHNHC-T, AT45DB021E-SSHN-T, and AT45DB021E-SSHNHA-T share identical electrical specifications including memory capacity, interface protocol, operating frequency, voltage range, and temperature range. Direct substitution is supported at the circuit level.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging? A: Packaging format affects supply chain logistics and assembly processes. Tape & Reel (TR) is standard for high-volume production. Cut Tape (CT) & Digi-Reel format provides flexibility for lower-volume or mixed-component orders. Both formats contain identical components in 8-SOIC packages.

Q: Can I substitute AT45DB021E-SSHN-T for AT45DB021E-SSHNHC-T in production? A: Yes, provided your assembly process accommodates Cut Tape & Digi-Reel format. All electrical and mechanical parameters are identical. Verify your pick-and-place equipment compatibility with the packaging format before implementation.

Q: Are there any compliance or certification differences between these parts? A: No. All three parts carry identical RoHS3 compliance, REACH Unaffected status, MSL rating of 1 (Unlimited), and active product status. Compliance certifications are equivalent across all substitute options.

Q: What determines which substitute part to select? A: Selection is based on packaging format availability, inventory levels, and assembly process requirements. Electrical performance and reliability are identical across all three part numbers.
