Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AT45DB161E-MHD-T are determined by strict equivalence in the following core parameters:

• Memory capacity: 16Mbit
• Package type: 8-UDFN Exposed Pad (5x6)
• Memory organization: 528 Bytes x 4096 pages
• Operating temperature range: -40°C ~ 85°C
• RoHS compliance: ROHS3 Compliant
• Mounting type: Surface Mount

Substitutes are grouped by packaging format (Cut Tape vs. Tape & Reel vs. Tray) and memory interface capability (standard SPI vs. SPI with Quad I/O). All listed substitutes maintain electrical and mechanical compatibility with the original part within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

AT45DB161E-MHF-T is the primary substitute for AT45DB161E-MHD-T. Both parts are electrically equivalent with identical memory capacity, interface, and clock frequency. The AT45DB161E-MHF-T is in Active product status and offers an expanded voltage supply range (2.3V ~ 3.6V vs. 2.5V ~ 3.6V), providing greater design flexibility. The difference is packaging format: Tape & Reel (TR) versus Cut Tape (CT). This part is suitable for high-volume production environments.

AT45DB161E-MHF-Y provides identical electrical specifications to AT45DB161E-MHF-T with Tray packaging. This format is appropriate for lower-volume applications or manual assembly processes.

AT45DQ161-MHF-T is a functional substitute with enhanced capability. It maintains 16Mbit capacity and 8-UDFN package compatibility but implements SPI - Quad I/O interface instead of standard SPI. This part is suitable only for designs that support Quad I/O protocol. The page write cycle time differs (6ms vs. 4ms), which must be evaluated against application timing requirements.

All substitute parts maintain ROHS3 compliance and are manufactured by Renesas Electronics Corporation.

Frequently Asked Questions (FAQ)

Q: Can AT45DB161E-MHF-T directly replace AT45DB161E-MHD-T in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is packaging format (Tape & Reel vs. Cut Tape). AT45DB161E-MHF-T has an expanded voltage supply range (2.3V minimum vs. 2.5V minimum), which is backward compatible with designs specified for 2.5V ~ 3.6V operation.

Q: What is the difference between AT45DB161E-MHF-T and AT45DQ161-MHF-T?

A: Both parts share identical memory capacity (16Mbit), package (8-UDFN), and clock frequency (85 MHz). The key difference is memory interface: AT45DB161E-MHF-T uses standard SPI, while AT45DQ161-MHF-T uses SPI - Quad I/O. Additionally, AT45DQ161-MHF-T has a page write cycle time of 6ms compared to 4ms for AT45DB161E-MHF-T. AT45DQ161-MHF-T is suitable only for applications designed to support Quad I/O protocol.

Q: Why is AT45DB161E-MHD-T marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. Renesas Electronics recommends using active alternatives (AT45DB161E-MHF-T or AT45DB161E-MHF-Y) for new product development. Existing inventory remains available for legacy system support.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, consistent with the original AT45DB161E-MHD-T specification.

Q: What packaging formats are available for substitutes?

A: AT45DB161E-MHF-T is supplied in Tape & Reel (TR) format, suitable for automated assembly. AT45DB161E-MHF-Y is supplied in Tray format, appropriate for manual or semi-automated processes. Both are compatible with the 8-UDFN (5x6) package specification.
