25LC010A-E/ST EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25LC010A-E/ST is a 1Kbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Microchip Technology. This non-volatile memory device operates at 10 MHz clock frequency with a 128 x 8 memory organization in an 8-TSSOP surface mount package. The part is currently active in production status with 2400 units in stock inventory.

Substitute parts are necessary when the original 25LC010A-E/ST becomes unavailable, when alternative manufacturers are preferred for supply chain diversification, or when design requirements allow for enhanced performance specifications such as higher clock frequency or extended voltage supply ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 25LC010A-E/ST are classified based on strict electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Memory Size: 1Kbit (mandatory match)
• Memory Organization: 128 x 8 (mandatory match)
• Memory Interface: SPI (mandatory match)
• Package Type: 8-TSSOP (mandatory match)
• Voltage Supply Range: Must encompass or be compatible with 2.5V ~ 5.5V
• Operating Temperature: Must support -40°C minimum and 125°C maximum, or be acceptable for the intended application temperature range

Secondary Performance Parameters:

• Clock Frequency: 10 MHz or higher is acceptable
• Write Cycle Time: 5ms or faster is acceptable
• RoHS Compliance: ROHS3 Compliant (all substitutes meet this requirement)

All substitute parts listed maintain identical memory capacity, organization, interface protocol, and physical package dimensions. Variations in clock frequency and voltage supply range represent performance enhancements or design flexibility rather than functional incompatibilities.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications):

• BR25H010FVT-2CE2 (Rohm Semiconductor): Matches all electrical parameters of the 25LC010A-E/ST. Includes AEC-Q100 automotive qualification and operates across the full -40°C ~ 125°C temperature range. Suitable for applications requiring automotive-grade reliability.
• CAV25010YE-GT3 (onsemi): Matches all electrical parameters of the 25LC010A-E/ST. Includes AEC-Q100 automotive qualification and operates across the full -40°C ~ 125°C temperature range. Suitable for automotive and industrial applications.

Enhanced Performance Substitutes (Higher Clock Frequency):

• AT25010B-XHL-T (Microchip Technology): Offers 20 MHz clock frequency with extended lower voltage support (1.8V minimum). Highest inventory availability (10200 Pcs). Suitable when higher data transfer rates are beneficial. Operating temperature range is -40°C ~ 85°C.
• AT25010B-XHL-B (Microchip Technology): Identical specifications to AT25010B-XHL-T with Tube packaging. Suitable when higher clock frequency is required with alternative packaging format.
• M95010-RDW6TP (STMicroelectronics): Offers 20 MHz clock frequency with extended lower voltage support (1.8V minimum). Suitable when higher data transfer rates are beneficial. Operating temperature range is -40°C ~ 85°C.
• M95010-WDW6TP (STMicroelectronics): Offers 20 MHz clock frequency with voltage supply range 2.5V ~ 5.5V matching the original part. Highest inventory availability among all substitutes (29200 Pcs). Suitable when higher clock frequency is required with matching voltage specifications.

All substitute parts maintain ROHS3 compliance and identical memory capacity, organization, and SPI interface protocol. Selection should be based on application temperature requirements, required clock frequency, voltage supply constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can AT25010B-XHL-T replace 25LC010A-E/ST in all applications? A: AT25010B-XHL-T is electrically compatible for applications operating within -40°C ~ 85°C temperature range. The original 25LC010A-E/ST supports -40°C ~ 125°C. If your application requires operation above 85°C, use BR25H010FVT-2CE2 or CAV25010YE-GT3 instead.

Q: What is the difference between M95010-RDW6TP and M95010-WDW6TP? A: Both parts offer identical 20 MHz clock frequency and 1Kbit memory capacity. The primary difference is voltage supply range: M95010-RDW6TP supports 1.8V ~ 5.5V, while M95010-WDW6TP supports 2.5V ~ 5.5V. M95010-WDW6TP matches the original 25LC010A-E/ST voltage range exactly.

Q: Are automotive-qualified substitutes available? A: Yes. BR25H010FVT-2CE2 (Rohm Semiconductor) and CAV25010YE-GT3 (onsemi) both carry AEC-Q100 automotive qualification and match all electrical specifications of the 25LC010A-E/ST.

Q: What does the 8-TSSOP package designation mean? A: 8-TSSOP refers to an 8-pin Thin Shrink Small Outline Package with 0.173" width and 4.40mm total width. All listed substitute parts use identical 8-TSSOP packaging, ensuring mechanical compatibility with existing PCB layouts.

Q: Can I use a higher clock frequency part as a direct replacement? A: Yes. Parts with 20 MHz clock frequency (AT25010B-XHL-T, AT25010B-XHL-B, M95010-RDW6TP, M95010-WDW6TP) are backward compatible with applications designed for 10 MHz operation. The higher clock frequency provides additional performance headroom without affecting functionality at lower speeds.

Q: What is Moisture Sensitivity Level (MSL) and why does it matter? A: MSL indicates the maximum time a component can be exposed to moisture before soldering. MSL 1 (Unlimited) means no time restriction. MSL 3 (168 Hours) means the component must be soldered within 168 hours of package opening. For most applications, MSL 1 parts are preferred for manufacturing flexibility.
