Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7202LA20TP is determined by the following critical parameters:

• Memory Configuration: Must be 1K x 9 (9K total) to maintain data width and depth compatibility
• Function: Must be asynchronous FIFO to preserve timing and control signal architecture
• Bus Directional: Must be uni-directional to match data flow requirements
• Package Type: Must be 28-DIP to ensure mechanical and electrical pin compatibility
• Voltage Supply Range: Must encompass or match 4.5V ~ 5.5V operating window
• Operating Temperature: Must support 0°C ~ 70°C range

The 7202LA12TPG qualifies as a direct substitute based on these parameters. While it offers improved performance characteristics (12ns access time and 50MHz data rate), it maintains identical memory configuration, function, bus directionality, package format, voltage supply range, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

The 7202LA12TPG is the qualified substitute for the 7202LA20TP based on the following engineering criteria:

Product Status: The 7202LA20TP is classified as obsolete, while the 7202LA12TPG maintains active product status with confirmed inventory availability (1067 pcs in stock versus 848 pcs for the obsolete part). Active status ensures continued manufacturing support and supply chain reliability.

Regulatory Compliance: The 7202LA12TPG achieves ROHS3 compliance, whereas the 7202LA20TP is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the substitute part satisfies compliance requirements.

Performance Enhancement: The substitute part provides superior performance specifications with 12ns access time and 50MHz data rate compared to the main part's 20ns and 33.3MHz. These improvements are backward-compatible with designs specified for the 7202LA20TP, as faster access times and higher data rates do not introduce incompatibility in systems designed for the slower part.

Electrical and Mechanical Compatibility: Both parts share identical memory configuration, function, bus directionality, package format, voltage supply range, maximum current draw, and operating temperature specifications, ensuring direct pin-for-pin and functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 7202LA12TPG be used as a direct replacement for the 7202LA20TP in existing designs?

A: Yes. The 7202LA12TPG is electrically and mechanically compatible with the 7202LA20TP. Both parts feature identical 28-DIP packaging, 1K x 9 memory configuration, asynchronous FIFO function, uni-directional bus architecture, 4.5V to 5.5V supply voltage range, and 0°C to 70°C operating temperature. The substitute part's faster access time (12ns versus 20ns) and higher data rate (50MHz versus 33.3MHz) are backward-compatible with designs specified for the original part.

Q: What are the key differences between these two parts?

A: The primary differences are access time (12ns versus 20ns), data rate (50MHz versus 33.3MHz), product status (active versus obsolete), and RoHS compliance (ROHS3 compliant versus non-compliant). All other electrical and mechanical parameters remain identical.

Q: Is the 7202LA12TPG available in the same package as the 7202LA20TP?

A: Yes. Both parts are packaged in 28-DIP (0.300", 7.62mm) format with through-hole mounting, ensuring identical PCB footprint and assembly compatibility.

Q: Why should I consider the 7202LA12TPG over the 7202LA20TP?

A: The 7202LA12TPG is the recommended choice for new designs and ongoing production due to its active product status, ROHS3 compliance, superior performance specifications, and confirmed inventory availability. The obsolete status of the 7202LA20TP creates long-term supply chain risk.

Q: Are there any timing considerations when substituting the 7202LA12TPG for the 7202LA20TP?

A: No timing conflicts arise from this substitution. The 7202LA12TPG's faster access time and higher data rate represent performance improvements that do not introduce incompatibility with systems designed for the slower 7202LA20TP specifications.
