Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24C01CT-I/MC is determined by the following critical parameters:

Memory Specifications: Equivalent parts must provide 1Kbit capacity with 128 x 8 organization and I2C interface protocol at 400 kHz operation.

Physical Configuration: Substitute parts must use identical 8-DFN (2x3) surface mount package with 8-VFDFN exposed pad configuration to ensure PCB footprint compatibility.

Electrical Compatibility: Operating temperature range of -40°C to 85°C and supply voltage tolerance must be maintained or exceeded.

Compliance & Certification: Parts must maintain ROHS3 compliance, identical MSL rating (3, 168 Hours), and equivalent regulatory status (REACH Unaffected, EAR99 ECCN).

Manufacturing Status: Active production status ensures availability and long-term supply continuity.

The 24LC01BT-I/MC meets all substitution criteria as a direct equivalent part from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both the 24C01CT-I/MC and 24LC01BT-I/MC are active production parts from Microchip Technology with identical ROHS3 compliance and regulatory certifications. Selection between these parts should be based on application-specific requirements for supply voltage range and write cycle timing.

The 24C01CT-I/MC operates within a narrower supply voltage window (4.5V ~ 5.5V) compared to the 24LC01BT-I/MC (2.5V ~ 5.5V). Applications requiring operation at lower supply voltages should specify the 24LC01BT-I/MC.

The 24C01CT-I/MC provides faster access time (900 ns) and shorter write cycle time (1 ms) relative to the 24LC01BT-I/MC (4.6 µs access time, 5 ms write cycle time). Applications with timing-critical read or write operations should specify the 24C01CT-I/MC.

Both parts maintain identical MSL ratings and thermal operating ranges, ensuring equivalent reliability in standard manufacturing and field environments.

Frequently Asked Questions (FAQ)

Q: Can the 24LC01BT-I/MC be used as a direct replacement for the 24C01CT-I/MC?

A: Yes, the 24LC01BT-I/MC is a direct substitute for the 24C01CT-I/MC in applications where the extended lower supply voltage range (2.5V minimum) and longer write cycle time (5 ms) are acceptable. Both parts share identical memory capacity, I2C interface, clock frequency, package configuration, and operating temperature range.

Q: What are the key differences between these two parts?

A: The primary differences are supply voltage range and timing specifications. The 24C01CT-I/MC requires 4.5V minimum supply voltage and offers faster access time (900 ns) and write cycle time (1 ms). The 24LC01BT-I/MC operates at 2.5V minimum supply voltage with slower access time (4.6 µs) and write cycle time (5 ms).

Q: Are both parts available in the same package?

A: Yes, both the 24C01CT-I/MC and 24LC01BT-I/MC use the 8-DFN (2x3) surface mount package with 8-VFDFN exposed pad configuration, ensuring identical PCB footprint compatibility.

Q: Do these parts have the same moisture sensitivity rating?

A: Yes, both parts carry MSL rating 3 (168 Hours), indicating identical moisture sensitivity and requiring equivalent handling and storage protocols.

Q: Are both parts RoHS compliant?

A: Yes, both the 24C01CT-I/MC and 24LC01BT-I/MC are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
