Substitute Part Grouping Explanation

Substitution eligibility is determined by the following core parameters: memory size (1Kbit), memory organization (128 x 8), interface type (I2C), write cycle time (5ms), and mounting type (surface mount). Parts are grouped into three categories based on allowed variations:

Category 1: Parametric Equivalents (Identical Specifications) Parts with matching clock frequency (400 kHz), access time (900 ns), supply voltage range (1.5V ~ 3.6V), and operating temperature (-20°C ~ 85°C). Package variations between 8-MSOP and 8-TSSOP are permitted within this category.

Category 2: MFR Recommended Substitutes (Enhanced Performance) Parts with higher clock frequency (1 MHz) or extended temperature range (-40°C ~ 85°C) while maintaining 1Kbit capacity, I2C interface, and 5ms write cycle time. Supply voltage ranges may differ (1.7V ~ 3.6V or 1.6V ~ 5.5V or 1.8V ~ 5.5V).

Category 3: Alternative Manufacturer Options Rohm Semiconductor parts (BR24 series) offering equivalent 1Kbit I2C EEPROM functionality with varying clock frequencies and package options, maintaining core memory specifications and compliance requirements.

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications) The 24VL014/MS serves as a parametric equivalent with identical electrical and thermal specifications. Both parts are manufactured by Microchip Technology and maintain active product status with ROHS3 compliance.

For Extended Temperature Range Applications AT24C01D-XHM-B and AT24C01D-XHM-T support operating temperatures from -40°C to 85°C compared to the original -20°C to 85°C range. These parts operate at 1 MHz clock frequency with 4.5 µs access time. AT24C01D-XHM-T is available in Cut Tape & Digi-Reel packaging with higher inventory availability (5300 pcs).

For Alternative Manufacturer Sourcing Rohm Semiconductor BR24 series parts provide 1Kbit I2C EEPROM functionality with extended supply voltage range (1.6V ~ 5.5V or 1.8V ~ 5.5V). BR24L01AFVM-WTR and BR24T01FVM-WTR maintain 400 kHz operation in 8-MSOP packaging with active product status. BR24G01FVM-3AGTTR offers 1 MHz operation for higher-speed applications.

Product Status Considerations Parts designated "Not For New Designs" (BR24G01FVJ-3GTE2, BR24L01AFV-WE2) are available for existing designs but should not be selected for new development. All Microchip AT24C01D and 24VL014 variants maintain active status suitable for new designs.

Frequently Asked Questions (FAQ)

Q: Can AT24C01D-XHM-B replace 24VL014H/MS directly? A: AT24C01D-XHM-B is functionally compatible as a 1Kbit I2C EEPROM with identical memory organization (128 x 8) and write cycle time (5ms). The part operates at higher clock frequency (1 MHz vs 400 kHz) and extended temperature range (-40°C to 85°C vs -20°C to 85°C). Package differs (8-TSSOP vs 8-MSOP), requiring PCB layout verification. Supply voltage minimum is higher (1.7V vs 1.5V).

Q: What is the difference between 24VL014H/MS and 24VL014/MS? A: Both parts are parametric equivalents with identical specifications: 1Kbit capacity, 400 kHz I2C operation, 900 ns access time, 1.5V ~ 3.6V supply range, and -20°C ~ 85°C operating temperature. Both use 8-MSOP packaging and maintain active product status with ROHS3 compliance.

Q: Are Rohm BR24 series parts compatible with Microchip 24VL014H/MS? A: Rohm BR24 series parts maintain core compatibility as 1Kbit I2C EEPROM devices with 128 x 8 organization and 5ms write cycle time. Key differences include extended supply voltage range (1.6V ~ 5.5V or 1.8V ~ 5.5V vs 1.5V ~ 3.6V), extended temperature range (-40°C ~ 85°C vs -20°C ~ 85°C), and varying clock frequencies. Package options differ between 8-MSOP, 8-TSSOP, and 8-LSSOP variants.

Q: Which substitute offers the best inventory availability? A: BR24L01AFVM-WTR provides highest inventory (15,690 pcs) with active product status, 400 kHz operation, and 8-MSOP packaging. BR24T01FVM-WTR offers comparable availability (15,300 pcs) with identical specifications.

Q: What packaging options are available for 1Kbit I2C EEPROM substitutes? A: Available packages include 8-MSOP (0.110" to 0.118" width), 8-TSSOP (0.173", 4.40mm width), and 8-LSSOP (0.173", 4.40mm width). Package selection affects PCB footprint and thermal characteristics. Verify PCB layout compatibility before substitution.

Q: Can I use a 1 MHz part in a 400 kHz application? A: Yes. AT24C01D-XHM-B and AT24C01D-XHM-T operate at 1 MHz but are backward compatible with 400 kHz I2C bus speeds. The device will operate correctly at lower clock frequencies. Verify system I2C bus configuration and pull-up resistor values for proper operation.
