Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7202LA30TDB is determined by the following critical parameters:

Core Functional Requirements:

• Memory capacity: 9K (1K x 9) configuration
• FIFO architecture: Asynchronous operation
• Bus structure: Uni-Directional
• Voltage compatibility: 4.5V ~ 5.5V supply range
• Base product series: 7200 family

Performance Characteristics:

• Access time and data rate must meet or exceed the original specification (30ns access time, 25MHz operation)
• Supply current must not exceed system power budget constraints

Physical and Environmental Constraints:

• Operating temperature range must encompass or exceed -55°C ~ 125°C
• Package form factor and mounting type may differ if electrical and functional parameters remain compatible

The 7202LA12JG qualifies as a manufacturer-recommended substitute based on identical memory configuration, matching voltage supply range, superior performance specifications (12ns access time, 50MHz data rate), and retention of core asynchronous FIFO functionality with uni-directional bus architecture.

Parameter Comparison

Engineering Selection Recommendations

The 7202LA12JG is the manufacturer-recommended substitute for the 7202LA30TDB. Selection of this alternative is supported by the following engineering factors:

Functional Compatibility: The substitute maintains identical memory architecture (9K, 1K x 9), asynchronous FIFO operation, and uni-directional bus configuration. Voltage supply requirements are identical (4.5V ~ 5.5V), ensuring direct electrical compatibility within existing power distribution systems.

Performance Enhancement: The 7202LA12JG provides superior performance specifications with 12ns access time and 50MHz data rate, compared to the original 30ns and 25MHz. This performance margin accommodates system timing requirements without degradation. Supply current is reduced to 80mA maximum, improving power efficiency.

Product Status and Compliance: The 7202LA12JG carries Active product status, ensuring continued availability and manufacturer support. ROHS3 compliance status meets modern regulatory requirements, whereas the original part is RoHS non-compliant. Both parts maintain REACH Unaffected status and identical ECCN/HTSUS classifications.

Design Considerations: Package transition from 28-CDIP through-hole to 32-LCC surface-mount requires PCB layout modification. Operating temperature range narrows from -55°C ~ 125°C to 0°C ~ 70°C; applications requiring extended low-temperature operation below 0°C must evaluate alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the 7202LA12JG directly replace the 7202LA30TDB without circuit modification?

A: Electrical and functional compatibility is confirmed. However, package transition from 28-CDIP through-hole to 32-LCC surface-mount requires PCB redesign. Pin-to-pin correspondence must be verified against device datasheets before implementation.

Q: What are the key differences between these parts?

A: The substitute offers faster access time (12ns vs. 30ns) and higher data rate (50MHz vs. 25MHz). Operating temperature range is narrower (0°C ~ 70°C vs. -55°C ~ 125°C). Supply current is lower (80mA vs. 100mA). RoHS compliance status differs (ROHS3 vs. non-compliant).

Q: Is the 7202LA12JG suitable for applications requiring -55°C operation?

A: No. The substitute operates from 0°C ~ 70°C. Applications requiring -55°C minimum temperature must retain the original part or identify alternative FIFO solutions with extended temperature specifications.

Q: Why is the original part obsolete?

A: The 7202LA30TDB is classified as obsolete by the manufacturer. The 7202LA12JG represents the active product line continuation within the 7200 series, offering improved performance and modern compliance standards.

Q: Are there inventory considerations for this substitution?

A: The 7202LA30TDB has 1025 pieces in stock (new original). The 7202LA12JG has 1155 pieces available (new original). Both parts are currently available through authorized distribution channels.
