AT45DB021E-SHNHA-T Equivalent & Substitute Parts

Part Overview

The AT45DB021E-SHNHA-T is a 2Mbit FLASH memory IC manufactured by Renesas Electronics Corporation, designed for SPI interface applications operating at 70 MHz. This non-volatile memory device is configured as 264 Bytes × 1024 pages and is supplied in an 8-SOIC surface mount package. The part is currently in active production status and is ROHS3 compliant. Substitute parts are identified when packaging format or supplier device configuration differs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT45DB021E-SHNHA-T are identified based on matching all critical electrical parameters: memory capacity (2Mbit), memory format (FLASH), memory organization (264 Bytes × 1024 pages), interface protocol (SPI), clock frequency (70 MHz), write cycle times (8µs word, 3ms page), supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and physical package specification (8-SOIC, 0.209" × 5.30mm). Substitution is permitted when packaging format (Tape & Reel versus Tube) or supplier device package designation differs, provided all electrical characteristics and mechanical dimensions remain identical. The base product number AT45DB021 remains constant across all qualified substitutes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—AT45DB021E-SHNHA-T, AT45DB021E-SHN-B, and AT45DB021E-SHN-T—are manufactured by Renesas Electronics Corporation and maintain active product status. All parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The primary distinction between parts is packaging format: AT45DB021E-SHNHA-T and AT45DB021E-SHN-T are supplied in Tape & Reel format suitable for automated assembly processes, while AT45DB021E-SHN-B is supplied in Tube format suitable for manual handling or lower-volume applications. Selection should be based on assembly process requirements and inventory management practices rather than electrical performance, as all three parts deliver identical functional specifications.

Frequently Asked Questions (FAQ)

Q: Can AT45DB021E-SHN-B (Tube packaging) be used as a direct replacement for AT45DB021E-SHNHA-T (Tape & Reel packaging)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. AT45DB021E-SHN-B is suitable for applications where manual component handling or lower-volume assembly is employed, while AT45DB021E-SHNHA-T is optimized for high-volume automated pick-and-place assembly.

Q: Are there any functional differences between AT45DB021E-SHN-T and AT45DB021E-SHNHA-T?

A: No. Both parts are supplied in Tape & Reel format and share identical electrical specifications, memory organization, interface protocol, and operating parameters. They are functionally interchangeable.

Q: What determines substitutability for the AT45DB021E series?

A: Substitutability is determined by matching memory capacity (2Mbit), memory format (FLASH), memory organization (264 Bytes × 1024 pages), interface type (SPI), clock frequency (70 MHz), write cycle times, supply voltage range (1.65V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and physical package dimensions (8-SOIC, 0.209" × 5.30mm). Packaging format variation does not affect substitutability.

Q: Are all listed substitutes currently in active production?

A: Yes. AT45DB021E-SHNHA-T, AT45DB021E-SHN-B, and AT45DB021E-SHN-T are all in active production status with current inventory availability.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited) and regulatory classifications.
