Equivalent & Substitute Parts for 24VL024HT/ST

Part Overview

The 24VL024HT/ST is a 2Kbit EEPROM memory IC with I2C interface manufactured by Microchip Technology. This non-volatile memory device operates at 400 kHz clock frequency with 900 ns access time, packaged in 8-TSSOP surface mount configuration. The part is currently active in production and ROHS3 compliant.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in circuit applications. Substitution candidates must maintain compatibility across memory capacity, interface protocol, package type, and voltage supply range.

Substitute Part Grouping Explanation

Substitution logic is based on the following critical parameters that must align with the main part:

Memory capacity: 2Kbit (256 x 8 organization)
Interface protocol: I2C
Package type: 8-TSSOP or compatible 8-pin surface mount variants
Write cycle time: 5ms

Substitute parts are grouped into two categories:

Category 1: Parametric Equivalents — Parts with identical electrical specifications (400 kHz clock frequency, 900 ns access time, 1.5V ~ 3.6V supply voltage). These provide direct functional replacement with no circuit modifications required.

Category 2: MFR Recommended Substitutes — Parts with enhanced specifications (higher clock frequency, extended temperature range, or wider voltage supply range). These offer superior performance characteristics while maintaining core 2Kbit I2C EEPROM functionality.

Engineering Selection Recommendations

For Active Production Designs:

Use 24VL025T/ST as the primary parametric equivalent. This part maintains identical electrical specifications and operating characteristics as the 24VL024HT/ST while remaining in active production status.

For applications requiring enhanced performance, AT24C02D-XHM-B or AT24C02D-XHM-T provide higher clock frequency (1 MHz) and extended temperature range (-40°C ~ 85°C). Both are active production parts from Microchip Technology with ROHS3 compliance.

Rohm Semiconductor alternatives (BR24G02FVJ-3AGTE2, BR24G02FVM-3GTTR, BR24G02FVT-3AGE2, BR24G02FVT-3GE2) are active production options offering wider voltage supply range (1.6V ~ 5.5V) and extended temperature range. Package variations include 8-TSSOP and 8-MSOP configurations.

For Legacy or Maintenance Applications:

BR24G02FV-3GTE2, BR24G02FVJ-3GTE2, and BR24L02FVJ-WE2 are marked "Not For New Designs" and should be used only for replacement in existing systems where original part sourcing is unavailable.

All recommended substitutes maintain ROHS3 compliance and MSL 1 moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can AT24C02D-XHM-B replace 24VL024HT/ST directly?

A: Yes. Both are 2Kbit I2C EEPROM devices in 8-TSSOP packages with 5ms write cycle time and ROHS3 compliance. The AT24C02D-XHM-B operates at 1 MHz (versus 400 kHz) and supports -40°C ~ 85°C temperature range (versus -20°C ~ 85°C), providing enhanced performance. Circuit operation is compatible without modifications.

Q: What is the difference between 24VL025T/ST and 24VL024HT/ST?

A: Both parts are parametric equivalents with identical memory capacity (2Kbit), interface (I2C 400 kHz), access time (900 ns), voltage supply (1.5V ~ 3.6V), and operating temperature (-20°C ~ 85°C). The primary difference is packaging: 24VL025T/ST is supplied in Cut Tape (CT) format while 24VL024HT/ST is supplied in Tape & Reel (TR) format.

Q: Are Rohm Semiconductor BR24G02 parts compatible with Microchip 24VL024HT/ST?

A: Yes, for applications within the overlapping voltage range. BR24G02 variants maintain 2Kbit I2C EEPROM functionality and 8-TSSOP packaging. However, BR24G02 parts support wider voltage supply (1.6V ~ 5.5V) compared to 24VL024HT/ST (1.5V ~ 3.6V). Verify circuit voltage requirements before substitution.

Q: Why are some substitute parts marked "Not For New Designs"?

A: Parts designated "Not For New Designs" (BR24G02FV-3GTE2, BR24G02FVJ-3GTE2, BR24L02FVJ-WE2) indicate manufacturer end-of-life or transition status. These parts remain available for existing system maintenance but should not be selected for new product development. Active production alternatives are recommended for new designs.

Q: What package options are available for 2Kbit I2C EEPROM substitutes?

A: Standard packages include 8-TSSOP (0.173", 4.40mm width) and 8-MSOP (0.110" to 0.118" width). BR24G02FVM-3GTTR uses 8-MSOP packaging. Verify PCB layout compatibility before selecting alternative package types, as pin spacing differs between TSSOP and MSOP variants.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, matching the compliance profile of 24VL024HT/ST.
