Renesas 7200L35TP Asynchronous FIFO Logic IC - Equivalent & Substitute Parts

Part Overview

The Renesas 7200L35TP is an asynchronous FIFO (First-In-First-Out) memory IC with 2.25K capacity (256 x 9 bits) designed for uni-directional data buffering applications. This 28-PDIP through-hole component operates at 22.2MHz with a 35ns access time and is rated for 0°C to 70°C operating temperature range. The 7200L35TP is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new production runs where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7200L35TP is determined by the following critical parameters:

• Memory Architecture: Identical 2.25K (256 x 9) capacity and asynchronous function
• Electrical Interface: Matching 4.5V ~ 5.5V supply voltage and 80mA maximum current
• Bus Configuration: Uni-directional data flow requirement
• Physical Package: 28-DIP form factor with 0.300" (7.62mm) pitch for through-hole mounting
• Operating Temperature Range: 0°C ~ 70°C compatibility

The 7200L12TPG meets all substitution criteria. While it offers superior performance characteristics (50MHz data rate and 12ns access time versus the original 22.2MHz and 35ns), it maintains full backward compatibility with the electrical, mechanical, and functional specifications of the 7200L35TP. The faster access time and higher data rate of the substitute part do not create incompatibility; rather, they provide performance headroom in legacy applications.

Engineering Selection Recommendations

The 7200L12TPG is the direct substitute for the obsolete 7200L35TP based on the following engineering criteria:

Product Status: The 7200L35TP is classified as obsolete, while the 7200L12TPG maintains active product status with Renesas Electronics Corporation. This ensures ongoing availability and manufacturing support for the substitute part.

Compliance and Certifications: The 7200L12TPG is RoHS3 compliant, whereas the 7200L35TP is RoHS non-compliant. Both parts are REACH unaffected and carry the same ECCN (EAR99) and HTSUS (8542.32.0071) classifications. The improved compliance posture of the substitute part aligns with current regulatory requirements for electronic components.

Electrical and Mechanical Compatibility: The 7200L12TPG maintains identical supply voltage range (4.5V ~ 5.5V), maximum current draw (80mA), package form factor (28-DIP), and operating temperature range (0°C ~ 70°C). Pin-for-pin compatibility is assured.

Performance Enhancement: The substitute part delivers faster access time (12ns versus 35ns) and higher data rate capability (50MHz versus 22.2MHz). These performance improvements provide operational margin in existing circuit designs without requiring design modifications.

Frequently Asked Questions (FAQ)

Q: Is the 7200L12TPG a direct pin-for-pin replacement for the 7200L35TP?

A: Yes. Both parts use the 28-DIP package with identical pinout, voltage supply requirements (4.5V ~ 5.5V), and current specifications (80mA maximum). No circuit board modifications are required for substitution.

Q: Will the faster access time (12ns) and higher data rate (50MHz) of the 7200L12TPG cause compatibility issues in circuits designed for the 7200L35TP?

A: No. The substitute part's superior performance characteristics are backward compatible. Circuits designed for 35ns access time and 22.2MHz operation will function correctly with the faster 7200L12TPG. The faster part does not introduce timing violations in legacy designs.

Q: What is the difference in packaging between these parts?

A: The 7200L35TP is supplied in standard packaging, while the 7200L12TPG is supplied in tube packaging. Both use the identical 28-DIP (0.300", 7.62mm) form factor for through-hole mounting. Packaging format does not affect electrical or mechanical compatibility.

Q: Are there any compliance differences between the 7200L35TP and 7200L12TPG?

A: Yes. The 7200L12TPG is RoHS3 compliant, while the 7200L35TP is RoHS non-compliant. Both parts are REACH unaffected. For new designs and applications subject to RoHS requirements, the 7200L12TPG is the appropriate selection.

Q: Can I use the 7200L12TPG in applications where the 7200L35TP was originally specified?

A: Yes. The 7200L12TPG meets or exceeds all electrical, mechanical, and functional specifications of the 7200L35TP. It is suitable for direct substitution in maintenance, repair, and new production applications requiring 256 x 9 asynchronous FIFO functionality in a 28-DIP through-hole package.

Q: What is the memory capacity of both parts?

A: Both the 7200L35TP and 7200L12TPG provide 2.25K memory capacity organized as 256 words by 9 bits. Memory size is identical between the two parts.
