7201LA15TP Equivalent & Substitute Parts

Part Overview

The 7201LA15TP is an asynchronous FIFO (First-In-First-Out) memory IC manufactured by Renesas Electronics Corporation. This device provides 4.5K storage capacity (512 x 9 bits) with a 15ns access time and 40MHz data rate in a 28-pin DIP package. The part is classified as obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations. The primary substitute maintains identical memory architecture and pinout while offering improved performance specifications and active product status.

Key Parameters

Substitute Part Grouping Explanation

The 7201LA12TPG qualifies as a direct substitute for the 7201LA15TP based on the following critical parameters:

• Memory Architecture: Identical 4.5K (512 x 9) configuration
• Function Type: Asynchronous FIFO operation
• Bus Configuration: Uni-Directional data flow
• Package Specification: 28-DIP (0.300", 7.62mm) with identical pinout
• Mounting Method: Through Hole
• Voltage Supply Range: 4.5V ~ 5.5V (identical)
• Current Supply (Max): 80mA (identical)
• Operating Temperature Range: 0°C ~ 70°C (identical)

The substitute part offers enhanced performance characteristics (12ns access time, 50MHz data rate) while maintaining full electrical and mechanical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The 7201LA12TPG is the qualified substitute for the 7201LA15TP based on the following factors:

Product Status: The 7201LA15TP is classified as obsolete, while the 7201LA12TPG maintains active product status with confirmed inventory availability (1035 pcs). This ensures long-term supply chain reliability and continued manufacturer support.

Regulatory Compliance: The 7201LA12TPG achieves ROHS3 compliance, whereas the 7201LA15TP is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

Performance Enhancement: The substitute part delivers superior performance with 12ns access time and 50MHz data rate compared to the original 15ns and 40MHz specifications. These improvements are backward-compatible with designs specified for the 7201LA15TP.

Electrical and Mechanical Compatibility: Identical supply voltage range (4.5V ~ 5.5V), maximum supply current (80mA), package dimensions (28-DIP), and operating temperature range (0°C ~ 70°C) ensure direct replacement capability without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the 7201LA12TPG replace the 7201LA15TP in existing designs?

A: Yes. The 7201LA12TPG is electrically and mechanically compatible with the 7201LA15TP. Both devices share identical memory capacity (512 x 9), supply voltage range (4.5V ~ 5.5V), current specifications (80mA max), and 28-DIP package configuration. The substitute part's improved access time (12ns vs. 15ns) and data rate (50MHz vs. 40MHz) are backward-compatible with designs specified for the original part.

Q: What are the key differences between these parts?

A: The primary differences are access time (12ns vs. 15ns), data rate (50MHz vs. 40MHz), product status (Active vs. Obsolete), and RoHS compliance (ROHS3 vs. non-compliant). All other electrical and mechanical parameters remain identical.

Q: Is the 28-DIP package identical between both parts?

A: Yes. Both the 7201LA15TP and 7201LA12TPG use the 28-DIP (0.300", 7.62mm) package with identical pinout and Through Hole mounting configuration. No PCB layout modifications are required for substitution.

Q: What is the supply voltage requirement for both parts?

A: Both parts operate within the identical supply voltage range of 4.5V to 5.5V. Maximum supply current for both devices is 80mA.

Q: Are there any temperature operating range differences?

A: No. Both parts operate across the identical temperature range of 0°C to 70°C.

Q: Why is the 7201LA15TP classified as obsolete?

A: The 7201LA15TP is an older generation asynchronous FIFO device. Renesas Electronics has transitioned this product to obsolete status, making the 7201LA12TPG the active equivalent with improved performance specifications and regulatory compliance.
