24C01C-I/MC EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 24C01C-I/MC is a 1Kbit EEPROM memory integrated circuit manufactured by Microchip Technology. This non-volatile memory device operates via I2C interface at 400 kHz clock frequency and is housed in an 8-DFN (2x3) surface mount package. The part is currently in active product status and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter range for this EEPROM category.

Substitute Part Grouping Explanation

Substitution validity for the 24C01C-I/MC is determined by the following critical parameters:

Memory capacity (1Kbit) and organization (128 x 8 bits)
I2C interface protocol at 400 kHz operation
8-DFN (2x3) package footprint and surface mount compatibility
Operating temperature range of -40°C to 85°C
ROHS3 compliance and REACH unaffected status

Substitute parts must maintain identical values across these parameters. Variations in supply voltage range, access time, write cycle time, and moisture sensitivity level are permitted within the allowed electrical and mechanical specifications for this product category, provided all critical parameters remain unchanged.

Engineering Selection Recommendations

All three parts maintain active product status from Microchip Technology and are ROHS3 compliant with REACH unaffected designation. Selection between 24C01C-I/MC, 24C01CT-I/MC, and 24LC01BT-I/MC is based on packaging requirements and supply voltage constraints:

The 24C01C-I/MC is supplied in Tube packaging. The 24C01CT-I/MC and 24LC01BT-I/MC are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

The 24LC01BT-I/MC supports extended supply voltage range (2.5V ~ 5.5V) compared to the 24C01C-I/MC and 24C01CT-I/MC (4.5V ~ 5.5V). This wider voltage tolerance may be advantageous in applications requiring lower supply voltage operation.

Access time and write cycle time differ between parts. The 24C01C-I/MC and 24C01CT-I/MC specify 900 ns access time and 1ms write cycle time. The 24LC01BT-I/MC specifies 4.6 µs access time and 5ms write cycle time. These timing differences must be evaluated against application performance requirements.

Frequently Asked Questions (FAQ)

Q: Can 24C01CT-I/MC replace 24C01C-I/MC in production?

A: Yes. Both parts are electrically and mechanically equivalent. The primary difference is packaging format: 24C01C-I/MC uses Tube packaging while 24C01CT-I/MC uses Tape & Reel (TR) packaging. Selection depends on assembly process requirements.

Q: What is the key difference between 24LC01BT-I/MC and the other substitutes?

A: The 24LC01BT-I/MC supports lower minimum supply voltage (2.5V versus 4.5V) and has slower access time (4.6 µs versus 900 ns) and longer write cycle time (5ms versus 1ms). All other critical parameters remain identical.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 8-DFN (2x3) package with identical pinout and footprint, enabling direct PCB substitution.

Q: Do supply voltage differences affect substitution eligibility?

A: The 24LC01BT-I/MC's wider supply voltage range (2.5V ~ 5.5V) makes it compatible with applications using the narrower range (4.5V ~ 5.5V) of 24C01C-I/MC and 24C01CT-I/MC. However, applications designed for 2.5V operation cannot use 24C01C-I/MC or 24C01CT-I/MC.

Q: Which part should be selected for high-volume automated assembly?

A: 24C01CT-I/MC or 24LC01BT-I/MC are recommended for automated assembly due to Tape & Reel (TR) packaging format, which is standard for pick-and-place equipment.

Q: Are timing specifications critical for substitution?

A: Timing specifications (access time and write cycle time) must be evaluated against application requirements. If the application requires 900 ns access time and 1ms write cycle time, only 24C01C-I/MC or 24C01CT-I/MC are suitable. If slower timing is acceptable, 24LC01BT-I/MC is a valid substitute.
