Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24VL014H/SN is determined by the following critical parameters: memory size (1Kbit), memory organization (128 x 8), I2C interface protocol, and surface mount packaging. Parts are classified into two substitution categories:

MFR Recommended Substitutes meet or exceed the electrical specifications of the primary part while maintaining full functional compatibility. These parts may feature enhanced performance characteristics such as higher clock frequency (1 MHz), extended supply voltage ranges, or broader operating temperature ranges.

Parametric Equivalents maintain identical electrical specifications and performance characteristics as the primary part, differing only in packaging format or manufacturer designation.

The following parameters determine substitution validity:

• Memory capacity: 1Kbit (non-negotiable)
• Memory organization: 128 x 8 (non-negotiable)
• Interface protocol: I2C (non-negotiable)
• Mounting type: Surface Mount (non-negotiable)
• Package compatibility: 8-SOIC or 8-SOP variants with equivalent pin configurations

Parameter Comparison

Engineering Selection Recommendations

AT24C01D-SSHM-B and AT24C01D-SSHM-T are MFR recommended substitutes from Microchip Technology offering enhanced I2C clock frequency at 1 MHz with extended operating temperature range to -40°C. Both parts maintain identical package dimensions and pin configuration. AT24C01D-SSHM-T provides higher inventory availability (11150 units) in Cut Tape & Digi-Reel format with verified programmability status. AT24C01D-SSHM-B is available in Bulk packaging (3100 units) with verified programmability. Both parts are ROHS3 compliant and suitable for direct substitution where higher clock frequency is acceptable.

24VL014/SN is a parametric equivalent from Microchip Technology with identical electrical specifications and performance characteristics. This part maintains the same 400 kHz clock frequency, 900 ns access time, and 1.5V to 3.6V supply range. Available in Tube packaging with 876 units in stock, this part serves as a direct functional replacement.

BR24G01F-3GTE2, BR24L01AF-WE2, and BR24T01F-WE2 are MFR recommended substitutes from Rohm Semiconductor. All three parts maintain 400 kHz I2C clock frequency and 1Kbit capacity with 128 x 8 organization. These parts feature extended supply voltage ranges (1.6V to 5.5V or 1.8V to 5.5V) and broader operating temperature ranges (-40°C to 85°C). Package dimensions differ slightly (8-SOP 0.173" width versus 8-SOIC 0.154" width), requiring PCB layout verification. BR24L01AF-WE2 offers the highest inventory availability (28200 units) with verified programmability status in Cut Tape & Digi-Reel format.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the primary part.

Frequently Asked Questions (FAQ)

Q: Can AT24C01D-SSHM-B or AT24C01D-SSHM-T be used as direct replacements for 24VL014H/SN?

A: Yes. Both AT24C01D parts are MFR recommended substitutes with identical 1Kbit capacity, 128 x 8 organization, and I2C interface. They maintain the same 8-SOIC package dimensions and pin configuration. The primary difference is enhanced I2C clock frequency (1 MHz versus 400 kHz) and extended operating temperature range (-40°C versus -20°C minimum). These enhancements provide superior performance without compromising compatibility.

Q: What is the difference between AT24C01D-SSHM-T and AT24C01D-SSHM-B?

A: Both parts are electrically identical with the same specifications. The difference is packaging format: AT24C01D-SSHM-T is supplied in Cut Tape & Digi-Reel format with higher inventory (11150 units) and MSL rating of 3 (168 hours), while AT24C01D-SSHM-B is supplied in Bulk format with lower inventory (3100 units) and MSL rating of 1 (unlimited). Selection depends on manufacturing process requirements and moisture handling procedures.

Q: Can Rohm Semiconductor parts (BR24G01F-3GTE2, BR24L01AF-WE2, BR24T01F-WE2) replace the Microchip 24VL014H/SN?

A: Yes, with package dimension verification. All Rohm parts maintain 1Kbit capacity, 128 x 8 organization, and 400 kHz I2C operation. The package footprint differs slightly: Rohm parts use 8-SOP with 0.173" width versus Microchip's 8-SOIC with 0.154" width. PCB layout and solder reflow profiles must be verified for compatibility. Rohm parts offer extended supply voltage ranges (1.6V to 5.5V) and broader operating temperatures (-40°C to 85°C).

Q: Is 24VL014/SN a suitable alternative to 24VL014H/SN?

A: Yes. 24VL014/SN is a parametric equivalent with identical electrical specifications, performance characteristics, and package dimensions. Both parts operate at 400 kHz I2C frequency with 900 ns access time and 1.5V to 3.6V supply range. The only difference is packaging format (Tube) and lower inventory availability (876 units).

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: 1Kbit memory capacity, 128 x 8 memory organization, I2C interface protocol, surface mount mounting type, and 8-SOIC or 8-SOP package variants with equivalent pin configurations. All substitute parts listed meet these criteria. Secondary parameters such as clock frequency, access time, and supply voltage range may differ but do not prevent substitution when the primary part is unavailable.

Q: Which substitute part offers the best inventory availability?

A: BR24L01AF-WE2 from Rohm Semiconductor offers the highest inventory availability with 28200 units in stock, supplied in Cut Tape & Digi-Reel format with verified programmability status. This part maintains 400 kHz I2C operation and 1Kbit capacity with extended supply voltage range (1.8V to 5.5V) and operating temperature range (-40°C to 85°C).
