Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the 24VL014T/SN are established based on the following critical parameters:

Core Compatibility Parameters:

• Memory capacity (1Kbit)
• Memory organization (128 x 8)
• Interface protocol (I2C)
• Package footprint (8-SOIC surface mount)
• Write cycle time (5 ms)

Performance Variation Parameters:

• Clock frequency (400 kHz baseline; higher frequencies acceptable)
• Access time (900 ns baseline; faster acceptable)
• Supply voltage range (1.5V ~ 3.6V baseline; wider ranges acceptable)
• Operating temperature range (-20°C ~ 85°C baseline; wider ranges acceptable)

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts with identical electrical specifications and packaging, differing only in packaging format (Tape & Reel versus Bulk).

MFR Recommended Substitutes: Parts with enhanced performance specifications (higher clock frequency, faster access time, wider voltage or temperature ranges) that maintain full backward compatibility with the original part's functional requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Parametric Equivalent: The 24VL014HT/SN is a direct parametric equivalent to the 24VL014T/SN, differing only in packaging format (Tape & Reel versus Bulk). Selection between these two Microchip parts depends solely on manufacturing process requirements and inventory management practices.

Microchip AT24C01D Series (AT24C01D-SSHM-T, AT24C01D-SSHM-B): These parts offer enhanced performance with 1 MHz clock frequency and 4.5 µs access time while maintaining the same 1Kbit capacity and I2C interface. Both parts support extended operating temperature range (-40°C to 85°C) and are ROHS3 compliant. The AT24C01D-SSHM-T variant in Cut Tape & Digi-Reel format has higher inventory availability (11,150 pcs) compared to the bulk variant (3,100 pcs). These parts are suitable for applications requiring faster I2C communication or broader temperature operating margins.

Rohm Semiconductor BR24 Series (BR24T01F-WE2, BR24G01F-3GTE2, BR24L01AF-WE2): All three Rohm parts maintain 1Kbit capacity and 400 kHz I2C operation with extended supply voltage range (1.6V ~ 5.5V or 1.8V ~ 5.5V) and -40°C to 85°C operating temperature. The BR24L01AF-WE2 offers the highest inventory availability (28,200 pcs) and is verified for DiGi-Electronics programmability. Package footprint differs slightly (0.173" width versus 0.154" width), requiring PCB layout verification. These parts are suitable for applications requiring wider voltage tolerance or extended temperature range.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements. Selection should prioritize parts with verified DiGi-Electronics programmability status when custom programming is required.

Frequently Asked Questions (FAQ)

Q: Can I use AT24C01D-SSHM-T as a direct replacement for 24VL014T/SN?

A: Yes. The AT24C01D-SSHM-T is functionally compatible as a substitute. It maintains identical memory capacity (1Kbit), organization (128 x 8), interface (I2C), and write cycle time (5 ms). The higher clock frequency (1 MHz versus 400 kHz) and faster access time (4.5 µs versus 900 ns) provide enhanced performance. Operating temperature range is extended to -40°C to 85°C. Package footprint is identical (8-SOIC, 0.154", 3.90mm width), requiring no PCB modifications.

Q: What is the difference between the Microchip and Rohm substitute options?

A: Microchip AT24C01D parts offer higher clock frequency (1 MHz) and faster access time (4.5 µs) while maintaining the original 400 kHz baseline. Rohm BR24 parts maintain 400 kHz operation but provide wider supply voltage range (1.6V ~ 5.5V or 1.8V ~ 5.5V versus 1.5V ~ 3.6V) and extended temperature range (-40°C to 85°C). Rohm parts use 8-SOP package with slightly larger width (0.173" versus 0.154"), requiring PCB layout verification before substitution.

Q: Are there packaging format considerations for substitution?

A: Yes. The original 24VL014T/SN is supplied in Bulk format. Equivalent parts are available in Tape & Reel (24VL014HT/SN, BR24T01F-WE2, BR24G01F-3GTE2) and Cut Tape & Digi-Reel formats (AT24C01D-SSHM-T, BR24L01AF-WE2). Packaging format selection depends on manufacturing process automation requirements and inventory management practices. Electrical and functional specifications remain identical across all packaging formats for the same base part number.

Q: Which substitute part has the best inventory availability?

A: BR24L01AF-WE2 has the highest inventory availability at 28,200 pcs. This Rohm part is also verified for DiGi-Electronics programmability. AT24C01D-SSHM-T has 11,150 pcs available in Cut Tape & Digi-Reel format. All substitute parts are currently in active product status with new original stock.

Q: Do I need to modify my PCB layout to use Rohm BR24 series parts?

A: Rohm BR24 parts use 8-SOP package with 0.173" width compared to the original 8-SOIC package with 0.154" width. While both are 8-pin surface mount packages with similar pin spacing, the slightly larger package width requires verification against your PCB footprint design. Pin configuration and electrical interface remain compatible. Consult your PCB design files and component placement constraints before substitution.

Q: What is the significance of "DiGi-Electronics Programmable" status?

A: DiGi-Electronics Programmable status indicates that the part has been verified for custom programming services through DiGi-Electronics. The original 24VL014T/SN and most substitute parts show "Not Verified" status. AT24C01D-SSHM-T and BR24L01AF-WE2 are verified for programmability. If custom programming is required, select parts with verified status or confirm programming capability with your supplier.

Q: Can I substitute parts with different clock frequencies?

A: Yes. The AT24C01D series operates at 1 MHz versus the original 400 kHz specification. Higher clock frequency is backward compatible and provides faster I2C communication. Applications designed for 400 kHz operation will function correctly with 1 MHz parts. However, verify that your I2C bus master supports the higher frequency if system-level timing constraints exist.
