Substitute Part Grouping Explanation

Substitute parts for the 24LC01BHT-I/MNY are qualified based on the following critical parameters that determine functional interchangeability:

Core Electrical Parameters: Memory capacity (1Kbit), memory organization (128 x 8), interface protocol (I2C), and clock frequency (400 kHz) must be identical across all substitutes.

Timing Specifications: Access time and write cycle time define performance characteristics. The 24LC01BHT-I/MNY specifies 900 ns access time; substitutes may vary in this parameter while maintaining functional compatibility within I2C protocol constraints.

Voltage Specifications: Supply voltage range determines circuit compatibility. The main part operates at 2.5V ~ 5.5V. Substitutes with extended lower voltage ranges (1.7V ~ 5.5V) are compatible in applications using the 2.5V ~ 5.5V window.

Physical Packaging: All substitutes maintain the 8-TDFN (2x3) surface mount package and 8-WFDFN Exposed Pad case specification for PCB compatibility.

Compliance & Status: All parts maintain Active product status, ROHS3 compliance, MSL Level 1, and identical ECCN/HTSUS classifications.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, qualifying them for equivalent application use. Selection between the main part and substitutes depends on specific application requirements:

24AA014T-I/MNY: Extends supply voltage range to 1.7V ~ 5.5V, enabling operation in low-voltage applications. Maintains identical memory specifications and 900 ns access time. Available in Cut Tape packaging.

24AA01HT-I/MNY: Extends supply voltage range to 1.7V ~ 5.5V with identical memory and timing specifications. Supplied in Tape & Reel packaging format, suitable for high-volume production environments.

24LC01BT-I/MNY: Maintains the 2.5V ~ 5.5V supply voltage range of the main part. Access time specification differs at 4.6 µs versus 900 ns; this slower access time remains compatible with 400 kHz I2C protocol operation. Available in Cut Tape packaging.

All parts share identical ECCN (EAR99), HTSUS (8542.32.0051), and MSL Level 1 classifications.

Frequently Asked Questions (FAQ)

Q: Can 24AA014T-I/MNY replace 24LC01BHT-I/MNY in all applications?

A: Yes, within the overlapping supply voltage range of 2.5V ~ 5.5V. The 24AA014T-I/MNY extends operation to 1.7V, but this additional capability does not affect compatibility in circuits designed for the original part's voltage specifications.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Both formats contain identical die and electrical specifications. Cut Tape is supplied in individual strips suitable for small-quantity applications. Tape & Reel format is wound on reels for automated assembly processes in high-volume production.

Q: Does the 4.6 µs access time of 24LC01BT-I/MNY affect I2C communication?

A: No. Both 900 ns and 4.6 µs access times are well within I2C protocol timing requirements at 400 kHz clock frequency. The slower access time does not degrade system performance.

Q: Are all substitute parts manufactured by Microchip Technology?

A: Yes. All listed substitutes are Microchip Technology products, maintaining consistent quality and reliability standards.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All parts share identical 8-TDFN (2x3) package dimensions and pin configurations, allowing direct PCB footprint compatibility.
