24LC512T-I/MF Equivalent & Substitute Parts

Part Overview

The 24LC512T-I/MF is a 512Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface communication at 400 kHz with 900 ns access time. This non-volatile memory device operates across a supply voltage range of 2.5V to 5.5V and is housed in an 8-VDFN Exposed Pad surface mount package. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when electrical specifications, memory organization, interface protocol, and physical packaging remain functionally equivalent across different packaging formats or voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 24LC512T-I/MF are qualified based on the following critical parameters that determine functional equivalence:

• Memory capacity and organization (512Kbit, 64K x 8 configuration)
• Communication protocol (I2C at 400 kHz)
• Electrical performance metrics (900 ns access time, 5ms write cycle)
• Physical package specification (8-VDFN Exposed Pad, 6x5mm)
• Supply voltage compatibility
• Operating temperature range
• Surface mount capability

The identified substitutes maintain identical memory specifications and package geometry. Variations in packaging format (Tape & Reel versus Tube versus Cut Tape) and voltage supply floor specifications do not affect functional interchangeability in circuit design.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with ROHS3 compliance and identical moisture sensitivity ratings. The 24LC512T-I/MF and 24LC512-I/MF are functionally equivalent with identical voltage supply specifications (2.5V ~ 5.5V), differing only in packaging format. The 24AA512T-I/MF offers extended lower voltage operation (1.7V minimum) while maintaining all other electrical and physical specifications. Selection between these parts depends on supply voltage requirements of the target application and packaging format availability. The 24AA512T-I/MF carries verified DiGi-Electronics programmability status, whereas the other variants show unverified status.

Frequently Asked Questions (FAQ)

Q: Can 24LC512-I/MF replace 24LC512T-I/MF in production?

A: Yes. Both parts share identical electrical specifications, memory organization, I2C interface, access timing, and 8-VDFN package geometry. The difference is packaging format: 24LC512T-I/MF uses Tape & Reel while 24LC512-I/MF uses Tube. Circuit functionality remains unchanged.

Q: What is the key difference between 24AA512T-I/MF and 24LC512T-I/MF?

A: The 24AA512T-I/MF supports lower minimum supply voltage (1.7V versus 2.5V). All other electrical parameters, memory capacity, interface protocol, and physical package specifications are identical. Use 24AA512T-I/MF when applications require operation 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). Direct PCB footprint compatibility is confirmed.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel, Tube, and Cut Tape formats are distribution methods only. Electrical specifications, memory performance, and interface characteristics remain identical across all packaging options.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification. Moisture sensitivity level is 1 (Unlimited) for all variants.
