7201LA25TP Equivalent & Substitute Parts

Part Overview

The 7201LA25TP 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 25ns access time and 28.5MHz 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.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7201LA25TP is determined by the following critical parameters:

• Memory capacity (512 x 9 bits)
• Asynchronous FIFO function
• Uni-directional bus architecture
• 28-pin DIP package with 0.300" (7.62mm) spacing
• Supply voltage range (4.5V ~ 5.5V)
• Through-hole mounting compatibility

The 7201LA12TPG qualifies as a direct substitute based on matching memory size, function, bus configuration, package type, voltage specifications, and mounting method. Performance parameters (access time and data rate) are improved in the substitute, making it backward-compatible for the 7201LA25TP application.

Parameter Comparison

Engineering Selection Recommendations

The 7201LA12TPG is the qualified substitute for the 7201LA25TP. Selection is based on the following factors:

The 7201LA12TPG maintains identical memory architecture, electrical specifications, and physical package dimensions required for direct replacement. The substitute offers improved performance characteristics with 12ns access time versus 25ns and 50MHz data rate versus 28.5MHz, providing enhanced speed capability within the same power envelope.

The 7201LA12TPG carries Active product status, ensuring continued availability and manufacturing support. The part meets ROHS3 compliance requirements, whereas the original 7201LA25TP is RoHS non-compliant. Both parts maintain identical supply voltage range, maximum current draw, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can the 7201LA12TPG directly replace the 7201LA25TP in existing designs?

A: Yes. The 7201LA12TPG is a direct substitute. Both parts share identical memory capacity (512 x 9 bits), asynchronous FIFO function, uni-directional bus architecture, 28-pin DIP package, supply voltage range (4.5V ~ 5.5V), and maximum current specifications (80mA). The substitute provides faster access time (12ns vs. 25ns) and higher data rate (50MHz vs. 28.5MHz), making it backward-compatible.

Q: Are there any package or pinout differences between these parts?

A: No. Both the 7201LA25TP and 7201LA12TPG use the 28-DIP package with 0.300" (7.62mm) spacing. Through-hole mounting compatibility is identical, allowing direct PCB substitution without layout modifications.

Q: What is the significance of the product status difference?

A: The 7201LA25TP is classified as Obsolete, indicating discontinued manufacturing and limited availability. The 7201LA12TPG is Active, ensuring ongoing production, supply chain availability, and manufacturer support for new designs and replacements.

Q: Does the RoHS compliance difference affect substitution?

A: The 7201LA12TPG meets ROHS3 compliance standards, while the 7201LA25TP is RoHS non-compliant. For applications requiring RoHS compliance, the 7201LA12TPG is the appropriate selection. For legacy systems without compliance requirements, both parts are electrically compatible.

Q: Are the electrical characteristics identical between these parts?

A: Supply voltage range (4.5V ~ 5.5V), maximum supply current (80mA), and operating temperature range (0°C ~ 70°C) are identical. The 7201LA12TPG provides superior performance with faster access time and higher data rate, but maintains full backward compatibility with the 7201LA25TP specifications.
