Equivalent & Substitute Parts for 25LC010AT-E/ST

Part Overview

The 25LC010AT-E/ST is a 1Kbit EEPROM memory IC manufactured by Microchip Technology, featuring SPI interface operation at 10 MHz with 8-TSSOP surface mount packaging. This non-volatile memory device operates across a supply voltage range of 2.5V to 5.5V and temperature range of -40°C to 125°C, with a 5ms write cycle time. The part is currently in active product status and ROHS3 compliant.

Substitute parts are necessary when the original part becomes unavailable, when packaging requirements differ, or when enhanced performance specifications (such as higher clock frequency or extended voltage range) are required for system optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC010AT-E/ST is determined by the following critical parameters:

Core Compatibility Requirements:

• Memory Size: 1Kbit (128 x 8 organization)
• Memory Interface: SPI
• Package Type: 8-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Memory Format: EEPROM, Non-Volatile

Performance Compatibility Parameters:

• Clock Frequency: 10 MHz minimum (higher frequencies are acceptable)
• Write Cycle Time: 5ms maximum (faster cycles are acceptable)
• Voltage Supply Range: Must encompass or exceed 2.5V ~ 5.5V
• Operating Temperature: Must support -40°C ~ 125°C range or be suitable for the intended application temperature window

All substitute parts listed maintain identical memory capacity, organization, interface protocol, and physical package dimensions. Variations in clock frequency, voltage range, temperature rating, and write cycle time represent performance enhancements or application-specific optimizations rather than functional incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

Direct Functional Equivalents (Identical Performance Profile): BR25H010FVT-2CE2 and CAV25010YE-GT3 provide direct substitution with matching clock frequency (10 MHz), voltage range (2.5V ~ 5.5V), and temperature rating (-40°C ~ 125°C). Both parts carry AEC-Q100 automotive qualification and are ROHS3 compliant. BR25H010FVT-2CE2 offers marginally faster write cycle time (4ms vs 5ms).

Enhanced Performance Substitutes (Higher Clock Frequency): AT25010B-XHL-T, AT25010B-XHL-B, M95010-RDW6TP, and M95010-WDW6TP operate at 20 MHz, providing doubled clock frequency capability. These parts maintain identical memory organization and SPI interface. All are ROHS3 compliant and in active product status. Temperature rating is reduced to -40°C ~ 85°C, and voltage range extends to 1.8V minimum (except M95010-WDW6TP which maintains 2.5V minimum).

Packaging Considerations: AT25010B-XHL-T offers Cut Tape & Digi-Reel packaging with unlimited moisture sensitivity level (MSL 1), suitable for high-volume automated assembly. AT25010B-XHL-B is supplied in Tube packaging. All other substitutes are supplied in Tape & Reel format matching the original part's packaging type.

Frequently Asked Questions (FAQ)

Q: Can AT25010B-XHL-T replace 25LC010AT-E/ST in all applications? A: AT25010B-XHL-T is functionally compatible at the memory interface level. The 20 MHz clock frequency is backward compatible with 10 MHz system designs. However, the reduced operating temperature range (-40°C ~ 85°C vs -40°C ~ 125°C) must be verified against application requirements. The extended voltage range (1.8V ~ 5.5V) provides broader supply compatibility.

Q: What is the difference between M95010-RDW6TP and M95010-WDW6TP? A: Both parts are STMicroelectronics M95010 EEPROM devices with identical 20 MHz clock frequency, 5ms write cycle time, and 8-TSSOP packaging. The primary difference is voltage supply range: M95010-RDW6TP operates from 1.8V ~ 5.5V, while M95010-WDW6TP operates from 2.5V ~ 5.5V. Selection depends on minimum supply voltage requirements in the target application.

Q: Are BR25H010FVT-2CE2 and CAV25010YE-GT3 suitable for automotive applications? A: Both parts carry AEC-Q100 automotive qualification and are suitable for automotive-grade applications. BR25H010FVT-2CE2 is manufactured by Rohm Semiconductor, and CAV25010YE-GT3 is manufactured by onsemi. Both maintain the full -40°C ~ 125°C operating temperature range required for automotive environments.

Q: What packaging format should be selected for high-volume production? A: AT25010B-XHL-T (Cut Tape & Digi-Reel) is optimized for automated pick-and-place assembly with unlimited moisture sensitivity level. For lower-volume applications or manual assembly, Tape & Reel format (25LC010AT-E/ST, BR25H010FVT-2CE2, CAV25010YE-GT3, M95010-RDW6TP, M95010-WDW6TP) or Tube packaging (AT25010B-XHL-B) may be more cost-effective.

Q: Can I use a 20 MHz substitute in a system designed for 10 MHz operation? A: Yes. The 20 MHz parts (AT25010B-XHL-T, AT25010B-XHL-B, M95010-RDW6TP, M95010-WDW6TP) are backward compatible with 10 MHz system designs. The SPI interface operates at the clock frequency specified by the host controller, so a 20 MHz-capable device will function correctly in a 10 MHz system without modification.
