Substitute Part Grouping Explanation

Substitution eligibility for the 24LC04B-I/MC is determined by strict equivalence across the following critical parameters:

• Memory capacity: 4Kbit
• Memory organization: 256 x 8 x 2 configuration
• Interface protocol: I2C at 400 kHz
• Electrical performance: 900 ns access time, 5 ms write cycle time
• Supply voltage: 2.5V ~ 5.5V operating range
• Temperature rating: -40°C ~ 85°C
• Package: 8-DFN (2x3) with exposed pad
• Compliance: RoHS3 and REACH unaffected status

The 24LC04BT-I/MC qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the main part's standard packaging, and carries verified DiGi-Electronics programmable status.

Frequently Asked Questions (FAQ)

Q: Can 24LC04BT-I/MC be used as a direct replacement for 24LC04B-I/MC in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 24LC04BT-I/MC differs only in packaging format (Tape & Reel versus standard packaging). No circuit design changes are required.

Q: What is the significance of the "T" designation in 24LC04BT-I/MC?

A: The "T" indicates Tape & Reel packaging format, which is standard for high-volume automated assembly operations. The electrical device itself is identical to the non-T variant.

Q: Are both parts suitable for -40°C to 85°C operating environments?

A: Yes. Both the 24LC04B-I/MC and 24LC04BT-I/MC are rated for -40°C to 85°C operating temperature range.

Q: What does "DiGi-Electronics Programmable: Verified" mean for the 24LC04BT-I/MC?

A: This certification confirms that the 24LC04BT-I/MC has been tested and verified for compatibility with DiGi-Electronics automated programming and assembly equipment.

Q: Are there any supply voltage differences between these parts?

A: No. Both parts operate across the identical 2.5V to 5.5V supply voltage range.

Q: Which part should be selected for low-volume prototyping?

A: The 24LC04B-I/MC with standard packaging is appropriate for prototyping and low-volume applications. The 24LC04BT-I/MC is optimized for production-volume orders requiring Tape & Reel format.
