Equivalent & Substitute Parts for 24VL014T/MS

Part Overview

The 24VL014T/MS is a 1Kbit EEPROM memory IC manufactured by Microchip Technology, featuring I2C interface with 400 kHz clock frequency and 8-MSOP surface mount packaging. This part is actively produced and widely used in embedded systems requiring non-volatile memory storage with low-voltage operation (1.5V to 3.6V supply range).

Substitute parts are necessary when the original packaging format (Tape & Reel) is unavailable, when alternative clock frequencies better suit application requirements, or when extended operating temperature ranges are required. Equivalent parts maintain the core 1Kbit capacity, I2C interface, and 128 x 8 memory organization while offering variations in packaging, speed grades, and voltage specifications.

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): 24VL014/MS is the direct equivalent, differing only in packaging format (Tube instead of Tape & Reel). Selection between these two depends solely on procurement and assembly requirements.

Microchip Technology AT24C01D Series (400 kHz and 1 MHz variants): AT24C01D-XHM-B and AT24C01D-XHM-T are manufacturer-recommended alternatives offering extended operating temperature range (-40°C to 85°C versus -20°C to 85°C). The 1 MHz clock frequency provides faster I2C communication. These parts are Active status and ROHS3 compliant. Package format is 8-TSSOP, requiring PCB layout adjustment from the 8-MSOP original.

Rohm Semiconductor BR24 Series: BR24G01FVM-3AGTTR provides 1 MHz operation in 8-MSOP package with Active status and extended voltage range (1.6V to 5.5V). BR24L01AFVM-WTR and BR24T01FVM-WTR maintain 400 kHz operation in 8-MSOP package with Active status. BR24L01AFVM-WTR includes verified programmability certification. All Rohm parts support extended voltage ranges and -40°C to 85°C operating temperature.

Package Considerations: 8-MSOP package variants (24VL014T/MS, 24VL014/MS, BR24G01FVM-3AGTTR, BR24L01AFVM-WTR, BR24T01FVM-WTR) maintain identical footprint compatibility. 8-TSSOP variants (AT24C01D-XHM-B, AT24C01D-XHM-T, BR24G01FVJ-3GTE2, BR24G01FVT-3GE2, BR24L01AFVT-WE2) require different PCB layout. 8-LSSOP variant (BR24L01AFV-WE2) is marked Not For New Designs.

Product Status Consideration: BR24G01FVJ-3GTE2 and BR24L01AFV-WE2 are marked Not For New Designs. These parts remain functionally equivalent but should not be selected for new product development. Active status parts are preferred for ongoing production.

Frequently Asked Questions (FAQ)

Q: Can I substitute 24VL014T/MS with 24VL014/MS? A: Yes. Both parts are identical in electrical specifications and package type. The only difference is packaging format: 24VL014T/MS is supplied in Tape & Reel while 24VL014/MS is supplied in Tube. Selection depends on assembly equipment compatibility and procurement requirements.

Q: What is the difference between 400 kHz and 1 MHz clock frequency variants? A: Clock frequency determines I2C communication speed. 400 kHz is the standard I2C speed; 1 MHz (Fast-mode I2C) enables faster data transfer. Both frequencies are compatible with I2C protocol. Selection depends on application timing requirements. Faster clock frequency does not affect memory capacity or data retention.

Q: Can I use BR24 series parts as direct replacements? A: BR24 series parts from Rohm Semiconductor are functionally equivalent in memory capacity, organization, and I2C interface. They differ in voltage supply range (1.6V to 5.5V versus 1.5V to 3.6V), operating temperature range, and package options. Verify your PCB layout supports the selected package type (8-MSOP, 8-TSSOP, or 8-LSSOP).

Q: Why do some substitute parts have extended temperature ranges? A: Extended operating temperature ranges (-40°C to 85°C versus -20°C to 85°C) indicate qualification for industrial or automotive applications. These parts maintain the same memory specifications but are tested and certified for wider environmental conditions. Use extended-range parts only if your application requires them, as they may have different availability or cost.

Q: What does "Not For New Designs" status mean? A: Parts marked "Not For New Designs" (BR24G01FVJ-3GTE2, BR24L01AFV-WE2) are still functional and available but are being phased out by manufacturers. These parts should not be selected for new product development. Use Active status parts for new designs to ensure long-term supply availability.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All parts listed are ROHS3 compliant, meeting environmental and hazardous substance restrictions. This compliance is maintained across all manufacturers and package variants.

Q: What packaging format should I select? A: Tape & Reel packaging is standard for automated assembly lines. Tube packaging is suitable for manual assembly or lower-volume production. Cut Tape & Digi-Reel provides flexibility for mixed-volume requirements. Package selection does not affect electrical performance; it depends on your assembly process and procurement workflow.

Q: Can I use AT24C01D parts as substitutes for 24VL014T/MS? A: Yes, with package layout considerations. AT24C01D-XHM-B and AT24C01D-XHM-T are manufacturer-recommended alternatives offering 1 MHz operation and extended temperature range. However, they use 8-TSSOP package instead of 8-MSOP, requiring PCB redesign. Electrical compatibility is confirmed; physical layout must be verified.
