25LC1024T-I/MF Equivalent & Substitute Parts

Part Overview

The 25LC1024T-I/MF is a 1Mbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Microchip Technology. This non-volatile memory device operates at 20 MHz with a supply voltage range of 2.5V to 5.5V and is housed in an 8-pin VDFN package with exposed pad. The device is actively produced and ROHS3 compliant, making it suitable for embedded systems requiring persistent data storage with SPI interface compatibility. Equivalent and substitute parts are identified based on matching electrical specifications, memory organization, interface protocol, and physical packaging to ensure functional interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC1024T-I/MF is determined by strict equivalence across the following critical parameters: memory capacity (1Mbit), memory organization (128K x 8), interface protocol (SPI), clock frequency (20 MHz), package type (8-VDFN Exposed Pad), and operating temperature range (-40°C ~ 85°C). Voltage supply range variations are permitted only when the substitute part's range encompasses or exceeds the main part's range. All identified substitutes maintain identical memory specifications and physical packaging, ensuring pin-compatible replacement without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The 25LC1024T-I/MF is the primary specification with verified programmability status and Cut Tape packaging. The 25LC1024-I/MF provides direct electrical equivalence with identical voltage and temperature specifications but differs in packaging format (Tube) and lacks programmability verification. The 25AA1024T-I/MF, designated as manufacturer recommended, extends the minimum supply voltage to 1.8V, providing broader voltage compatibility while maintaining all other electrical and physical specifications. Selection between these parts should be based on packaging requirements, supply voltage constraints of the target application, and programmability verification status as applicable to production workflows.

Frequently Asked Questions (FAQ)

Q: Can 25LC1024-I/MF replace 25LC1024T-I/MF in production? A: Yes. Both parts are electrically identical with matching memory capacity, interface, clock frequency, voltage range, and package type. The difference is packaging format (Tube versus Cut Tape). Verify packaging compatibility with assembly equipment before substitution.

Q: What is the key difference between 25LC1024T-I/MF and 25AA1024T-I/MF? A: The 25AA1024T-I/MF supports a lower minimum supply voltage of 1.8V compared to 2.5V for the 25LC1024T-I/MF. All other electrical specifications and physical packaging are identical. Use 25AA1024T-I/MF when the application requires operation at voltages below 2.5V.

Q: Are these parts pin-compatible? A: Yes. All three parts use the 8-VDFN Exposed Pad package with identical pinout and physical dimensions (6x5mm), enabling direct board-level substitution without layout modification.

Q: Does programmability verification affect functional compatibility? A: Programmability verification indicates DiGi-Electronics testing status and does not affect functional operation. It reflects internal quality assurance processes relevant to procurement workflows.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements for commercial and industrial applications.
