AT45DB041E-SHNHC-T Equivalent & Substitute Parts

Part Overview

The AT45DB041E-SHNHC-T is a 4Mbit FLASH memory IC manufactured by Renesas Electronics Corporation, designed for SPI interface applications operating at 85 MHz. This non-volatile memory device is packaged in 8-SOIC form factor and is currently in active production status. Substitute parts become necessary when the primary packaging format (Tape & Reel) is unavailable, when alternative packaging configurations are preferred for assembly processes, or when inventory constraints require sourcing from alternative stock positions while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT45DB041E-SHNHC-T is permissible with parts that maintain identical electrical specifications and mechanical compatibility. The critical parameters determining substitutability are: memory capacity (4Mbit), memory interface protocol (SPI), clock frequency (85 MHz), memory organization (264 Bytes x 2048 pages), write cycle timing (8µs word / 3ms page), supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and physical package format (8-SOIC with 5.30mm width). Packaging configuration (Tape & Reel versus Cut Tape & Digi-Reel) represents a logistics and assembly process variable rather than a functional or electrical constraint. All substitute parts listed maintain these core parameters without deviation.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with ROHS3 compliance and REACH unaffected classification. The AT45DB041E-SHN-T offers the highest current inventory availability (37,690 pcs) with Cut Tape and Digi-Reel packaging, suitable for mixed-volume assembly operations. The AT45DB041E-SHNHA-T provides Tape & Reel packaging identical to the main part with lower inventory levels (1,210 pcs). Selection between these substitutes should be based on assembly process requirements and packaging format compatibility rather than electrical performance, as all parts are functionally equivalent across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable with the AT45DB041E-SHNHC-T?

A: Yes. All substitute parts maintain identical electrical specifications including memory capacity, interface protocol, clock frequency, timing parameters, voltage range, and temperature operating range.

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

A: Tape & Reel (TR) provides continuous reel packaging for high-volume automated assembly. Cut Tape (CT) & Digi-Reel provides flexible packaging options suitable for mixed-volume or lower-volume production runs. Both formats contain identical components.

Q: Can I use AT45DB041E-SHN-T as a direct replacement in my assembly process?

A: Direct replacement is possible if your assembly equipment supports Cut Tape and Digi-Reel format. If your process requires Tape & Reel format specifically, AT45DB041E-SHNHA-T maintains the original packaging configuration.

Q: Are there any compliance or certification differences between these parts?

A: No. All parts share identical RoHS3 compliance status, REACH unaffected classification, and moisture sensitivity level ratings.

Q: Which substitute should I select based on inventory availability?

A: AT45DB041E-SHN-T provides the highest inventory position. Selection should prioritize your assembly process packaging requirements as the primary criterion.
