Substitute Part Grouping Explanation

Substitution for BR24C01-DW6TP is determined by strict alignment of the following critical parameters:

Memory capacity: 1Kbit with 128 x 8 organization
Interface protocol: I2C communication standard
Clock frequency: 400 kHz operation
Write cycle time: 5ms specification
Operating temperature range: -40°C to 85°C minimum
Package format: 8-TSSOP surface mount configuration
Supply voltage compatibility: Parts must support the 4.5V to 5.5V range or broader range that encompasses it

Substitute parts are grouped into two categories: manufacturer-recommended active alternatives and similar functionally equivalent devices from alternative manufacturers. All substitutes maintain identical memory organization, interface type, and thermal specifications while differing in supply voltage ranges, clock frequency capabilities, or packaging variants.

Engineering Selection Recommendations

For designs currently using BR24C01-DW6TP, the following selection criteria apply based on product status and compliance:

Rohm Semiconductor Active Alternatives: BR24G01FVT-3GE2, BR24L01AFVT-WE2, and BR24T01FVT-WE2 are manufacturer-recommended active substitutes. All three maintain ROHS3 compliance and identical memory specifications. BR24G01FVT-3GE2 and BR24T01FVT-WE2 extend supply voltage range to 1.6V minimum, providing broader operational flexibility. BR24L01AFVT-WE2 specifies 1.8V minimum supply voltage. BR24G01FVT-3AGE2 operates at 1 MHz clock frequency, exceeding the 400 kHz specification of the original part.

Microchip Technology Alternatives: The 24AA series devices (24AA01-I/ST, 24AA014-I/ST, 24AA014H variants, 24AA014HT-I/ST, 24AA014T-I/ST) are active products with identical 1Kbit capacity and 400 kHz I2C operation. All Microchip parts specify 1.7V minimum supply voltage, encompassing the original 4.5V to 5.5V range. Package variants include 8-TSSOP and 8-MSOP options. All listed parts maintain ROHS3 compliance and unlimited moisture sensitivity level rating.

Direct pin-compatible substitution is supported by parts maintaining 8-TSSOP package format. The 24AA014H-I/MS variant uses 8-MSOP package and requires PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can BR24G01FVT-3AGE2 substitute for BR24C01-DW6TP in existing designs?

A: BR24G01FVT-3AGE2 maintains identical memory capacity, organization, and I2C interface. The 1 MHz clock frequency exceeds the 400 kHz specification of the original part. I2C protocol backward compatibility supports operation at lower clock frequencies, allowing this part to function in designs specified for 400 kHz operation. Package format is 8-TSSOP-B, requiring verification of PCB footprint compatibility.

Q: What is the difference between 8-TSSOP and 8-TSSOP-B packages?

A: Both designations refer to 8-pin thin shrink small outline packages with 0.173" width and 4.40mm body dimension. The "-B" suffix indicates a package variant. Physical dimensions and pin assignments remain compatible for standard PCB layouts, though design verification is recommended.

Q: Are Microchip 24AA014 variants direct replacements for BR24C01-DW6TP?

A: Microchip 24AA014 series devices match the 1Kbit capacity, 128 x 8 organization, I2C interface, and 400 kHz clock frequency. Supply voltage range extends to 1.7V minimum, which encompasses the original 4.5V to 5.5V specification. Pin configuration and package format (8-TSSOP) are compatible. These parts are functionally equivalent for direct substitution.

Q: Does lower minimum supply voltage on substitute parts affect compatibility?

A: Substitute parts with lower minimum supply voltage (1.6V, 1.7V, or 1.8V) are compatible with designs operating at 4.5V to 5.5V. The lower minimum specification indicates broader operational range without affecting performance at the original voltage specification. No design modification is required.

Q: What packaging options are available for 1Kbit I2C EEPROM substitutes?

A: Standard packaging is 8-TSSOP (0.173", 4.40mm width). The 24AA014H-I/MS variant uses 8-MSOP (0.118", 3.00mm width) package, which requires PCB footprint modification. All other listed substitutes use 8-TSSOP or 8-TSSOP-B format, supporting direct PCB replacement.

Q: Are all listed substitute parts RoHS compliant?

A: All substitute parts listed maintain ROHS3 compliance status, matching the original BR24C01-DW6TP specification. REACH status is unaffected for all parts. Moisture sensitivity level is rated as 1 (Unlimited) across all alternatives.
