25LC080DT-I/MS EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25LC080DT-I/MS is an 8Kbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Microchip Technology. This non-volatile memory device operates at 10 MHz clock frequency with a supply voltage range of 2.5V to 5.5V and is housed in an 8-MSOP surface mount package. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design specifications allow for compatible alternatives from qualified manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC080DT-I/MS is determined by the following critical parameters:

Primary Substitution Criteria:

Memory capacity: 8Kbit
Memory organization: 1K x 8
Interface protocol: SPI
Package compatibility: 8-MSOP or 8-TSSOP footprint
Supply voltage range: Must support minimum 2.5V operation
Write cycle time: 5ms maximum
RoHS compliance: ROHS3 Compliant

Secondary Considerations:

Clock frequency: 10 MHz minimum (higher frequencies are acceptable)
Operating temperature range: -40°C minimum and 85°C maximum (extended ranges acceptable)
Packaging format: Tape & Reel, Cut Tape, or Tube formats are interchangeable for component selection

Substitute parts are grouped into two categories: direct equivalents from Microchip Technology with identical electrical specifications but different packaging, and cross-manufacturer alternatives that meet all electrical and mechanical requirements while maintaining functional compatibility.

Engineering Selection Recommendations

Direct Microchip Technology Equivalents (Recommended for Pin-Compatible Replacement):

The 25LC080D-I/MS is a direct functional equivalent differing only in packaging format (Tube versus Tape & Reel). This part maintains identical electrical specifications and 8-MSOP package footprint, making it suitable for direct substitution when packaging format availability changes.

The 25LC080AT-E/MS offers extended operating temperature range (-40°C to 125°C) while maintaining the same 8-MSOP footprint and 2.5V minimum supply voltage. This variant is appropriate when thermal performance requirements exceed the standard -40°C to 85°C specification.

Microchip 25AA080 Series (Lower Voltage Operation):

The 25AA080AT-I/MS and 25AA080CT-I/MS variants support lower minimum supply voltage (1.8V versus 2.5V) while maintaining all other electrical parameters. These parts are suitable for applications requiring extended low-voltage operation and are available in 8-MSOP packaging with different tape formats.

Higher Clock Frequency Alternatives (Package Change Required):

The AT25080B-XHL-B and AT25080B-XHL-T operate at 20 MHz clock frequency (double the primary part) in 8-TSSOP packaging. These require PCB layout modification due to different package dimensions (0.173" versus 0.118" width) but provide performance headroom for timing-critical applications.

Cross-Manufacturer Alternatives:

The BR25H080FVM-2CTR from Rohm Semiconductor matches the 8-MSOP footprint with identical 10 MHz clock frequency and 2.5V minimum supply voltage. This part includes automotive-grade qualification (AEC-Q100) and extended temperature range (-40°C to 125°C), with 4ms write cycle time meeting the 5ms specification.

The CAV25080YE-GT3 from onsemi provides 20 MHz operation in 8-TSSOP packaging with automotive qualification and extended temperature range, suitable for high-performance automotive applications.

The M95080-DFDW6TP from STMicroelectronics operates at 20 MHz in 8-TSSOP packaging with 1.7V minimum supply voltage, offering the lowest voltage floor among available alternatives.

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can I use 25AA080AT-I/MS as a direct replacement for 25LC080DT-I/MS?

A: Yes, the 25AA080AT-I/MS is functionally compatible. Both devices share identical 8Kbit capacity, 1K x 8 organization, SPI interface, 10 MHz clock frequency, 5ms write cycle time, and 8-MSOP packaging. The 25AA080AT-I/MS supports lower minimum supply voltage (1.8V versus 2.5V), making it suitable for applications operating at or above 2.5V.

Q: What is the difference between 8-MSOP and 8-TSSOP packages?

A: Both are 8-pin surface mount packages with different physical dimensions. The 8-MSOP measures 0.118" width (3.00mm), while the 8-TSSOP measures 0.173" width (4.40mm). Substitution between these packages requires PCB layout modification and cannot be performed without design changes.

Q: Can I use AT25080B-XHL-T instead of 25LC080DT-I/MS?

A: The AT25080B-XHL-T is electrically compatible with 20 MHz clock frequency (exceeding the 10 MHz requirement) and identical memory capacity. However, it uses 8-TSSOP packaging instead of 8-MSOP, requiring PCB redesign. The part is suitable only if layout modifications are acceptable.

Q: What does the extended temperature range on 25LC080AT-E/MS provide?

A: The 25LC080AT-E/MS operates from -40°C to 125°C compared to the standard -40°C to 85°C range. This extended upper temperature limit is necessary for applications in high-temperature environments such as automotive engine compartments or industrial equipment.

Q: Are automotive-qualified parts (BR25H080FVM-2CTR, CAV25080YE-GT3) required for non-automotive applications?

A: Automotive qualification (AEC-Q100) is not required for non-automotive applications. These parts are suitable for general-purpose use but may have different pricing and lead times. Selection should be based on application requirements rather than qualification status alone.

Q: What is the significance of the write cycle time difference between BR25H080FVM-2CTR (4ms) and 25LC080DT-I/MS (5ms)?

A: The BR25H080FVM-2CTR write cycle time of 4ms is faster than the 5ms specification of the primary part. This represents improved performance and does not create compatibility issues, as the substitute part completes write operations within the time budget of the original design.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes, all listed substitute parts maintain ROHS3 compliance, identical memory capacity, SPI interface, and compatible electrical specifications. Manufacturing processes may source parts from different manufacturers based on availability without affecting system functionality, provided package footprints remain consistent.
