Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201LA30LB is determined by the following critical parameters:

• Memory capacity: 4.5K (512 x 9 bits) configuration
• Asynchronous FIFO function with uni-directional bus architecture
• Supply voltage range: 4.5 V ~ 5.5 V compatibility
• Expansion capability: Depth and Width support
• Retransmit capability: Required
• Base product series: 7200 family

The 7201LA12JG qualifies as a substitute based on matching memory size, function type, bus directionality, voltage supply range, expansion type, and retransmit capability. Performance parameters (access time and data rate) exceed the original specification, providing improved operational characteristics within the same functional framework.

Parameter Comparison

Engineering Selection Recommendations

The 7201LA12JG is the designated manufacturer-recommended substitute for the 7201LA30LB. Selection of this substitute is supported by the following factors:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance satisfies current environmental and regulatory requirements
• Identical memory configuration and asynchronous FIFO function maintain circuit compatibility
• Matching voltage supply range and uni-directional bus architecture preserve electrical interface requirements
• Superior access time (12ns vs. 30ns) and data rate (50MHz vs. 25MHz) provide performance headroom
• Reduced maximum supply current (80mA vs. 100mA) offers improved power efficiency

The operating temperature range of the substitute (0°C ~ 70°C) is narrower than the original part (-55°C ~ 125°C). Applications requiring extended temperature operation must evaluate this limitation against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7201LA12JG directly replace the 7201LA30LB in existing designs?

A: The 7201LA12JG is functionally compatible as a substitute. Both devices share identical memory capacity (512 x 9), asynchronous FIFO architecture, uni-directional bus configuration, and supply voltage range. Package differences (32-CLCC vs. 32-LCC J-Lead) require PCB layout verification. Operating temperature range differences must be evaluated for specific application requirements.

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

A: The primary differences are access time (30ns vs. 12ns), data rate (25MHz vs. 50MHz), maximum supply current (100mA vs. 80mA), operating temperature range (-55°C ~ 125°C vs. 0°C ~ 70°C), package type (32-CLCC vs. 32-PLCC), and product status (Obsolete vs. Active). The substitute offers improved performance characteristics and regulatory compliance.

Q: Are there package compatibility considerations?

A: Yes. The 7201LA30LB uses 32-CLCC packaging (11.43x13.97mm), while the 7201LA12JG uses 32-PLCC packaging (14x11.46mm). Physical dimensions differ, requiring PCB footprint and layout verification before implementation.

Q: Does the substitute meet current compliance standards?

A: The 7201LA12JG is ROHS3 compliant, satisfying current environmental regulations. The original 7201LA30LB is RoHS non-compliant. Both parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: What is the impact of the narrower operating temperature range?

A: The substitute operates within 0°C ~ 70°C, compared to the original -55°C ~ 125°C range. Applications requiring operation below 0°C or above 70°C must evaluate alternative solutions or confirm that the substitute's temperature range meets system specifications.
