Substitute Part Grouping Explanation

Substitute parts for the 24VL024H/MS are classified based on strict alignment with core electrical and mechanical parameters. The primary substitution criteria are: memory capacity (2Kbit), memory organization (256 x 8), I2C interface protocol, and surface mount packaging. Parts are grouped into three categories:

Category 1: Parametric Equivalents — Parts maintaining identical clock frequency (400 kHz), access time (900 ns), supply voltage range (1.5V ~ 3.6V), and package footprint (8-MSOP). These parts are direct functional replacements with no design modifications required.

Category 2: MFR Recommended Substitutes — Parts with equivalent memory specifications but differing in clock frequency (1 MHz), access time (4.5 µs), supply voltage range (1.7V ~ 3.6V or 1.6V ~ 5.5V), or package variant (8-TSSOP). These require verification of timing and voltage compatibility within the application circuit.

Category 3: MFR Recommended Substitutes (Alternative Packages) — Parts with equivalent memory specifications in alternative surface mount packages (8-TSSOP, 8-SSOP-B, 8-MSOP variants) or from alternative manufacturers. Package footprint differences require PCB layout verification.

Engineering Selection Recommendations

For Direct Replacement (No Design Changes): The 24VL025/MS is a parametric equivalent offering identical electrical performance and package footprint. Both parts maintain 400 kHz clock frequency, 900 ns access time, and 1.5V to 3.6V supply voltage range. This part is in active production status.

For Enhanced Temperature Range: The AT24C02D-XHM-B and AT24C02D-XHM-T variants extend operating temperature to -40°C to 85°C and increase clock frequency to 1 MHz. These parts require PCB layout adjustment due to 8-TSSOP package footprint difference from the original 8-MSOP. Both are in active production status.

For Extended Supply Voltage Range: Rohm Semiconductor BR24G02 series parts (BR24G02FVM-3GTTR, BR24G02FVT-3AGE2, BR24G02FVT-3GE2) support 1.6V to 5.5V supply voltage, enabling operation in wider voltage environments. The BR24G02FVM-3GTTR maintains 8-MSOP package compatibility. BR24G02FVT variants use 8-TSSOP package. All are RoHS3 compliant and MSL Level 1.

For Legacy Applications: Parts marked "Not For New Designs" (BR24G02FV-3GTE2, BR24G02FVJ-3GTE2, BR24L02FVJ-WE2) remain available but should not be selected for new circuit designs. These are suitable only for sustaining production of existing products.

Compliance Considerations: All listed substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 (unlimited moisture sensitivity). EAR99 export classification and HTSUS code 8542.32.0051 apply uniformly across all parts.

Frequently Asked Questions (FAQ)

Q: Can I substitute 24VL024H/MS with 24VL025/MS without any circuit modifications?

A: Yes. The 24VL025/MS is a parametric equivalent with identical clock frequency (400 kHz), access time (900 ns), supply voltage range (1.5V ~ 3.6V), and 8-MSOP package footprint. No design changes are required.

Q: What is the primary difference between 24VL024H/MS and AT24C02D-XHM variants?

A: The AT24C02D-XHM series operates at 1 MHz clock frequency with 4.5 µs access time, compared to 400 kHz and 900 ns for the 24VL024H/MS. The AT24C02D variants also extend operating temperature to -40°C and use 8-TSSOP package instead of 8-MSOP. These differences require circuit verification before substitution.

Q: Are Rohm Semiconductor BR24G02 parts compatible with 24VL024H/MS applications?

A: BR24G02 parts maintain 2Kbit capacity and I2C interface but support extended supply voltage (1.6V ~ 5.5V) and wider operating temperature (-40°C ~ 85°C). Package variants differ: BR24G02FVM-3GTTR uses 8-MSOP; BR24G02FVT series use 8-TSSOP. Verify voltage and package compatibility before selection.

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

A: Available packages include 8-MSOP (0.118", 3.00mm width), 8-TSSOP (0.173", 4.40mm width), 8-LSSOP (0.173", 4.40mm width), and 8-SSOP-B variants. Package selection affects PCB layout and footprint requirements. Confirm PCB design compatibility before part selection.

Q: Should I use parts marked "Not For New Designs"?

A: Parts with "Not For New Designs" status (BR24G02FV-3GTE2, BR24G02FVJ-3GTE2, BR24L02FVJ-WE2) are restricted to sustaining production of existing products only. For new circuit designs, select parts with "Active" product status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 rating. Export classification (EAR99) and HTSUS code (8542.32.0051) are consistent across all parts.
