7201LA35TP Equivalent & Substitute Parts

Part Overview

The 7201LA35TP 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 35ns access time and operates at 22.2MHz data rate. The part is housed in a 28-pin DIP package and is designed for uni-directional data buffering applications requiring depth and width expansion capabilities.

The 7201LA35TP is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility, ensure continued availability, and support legacy equipment maintenance and redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201LA35TP is determined by the following critical parameters:

• Memory capacity: 4.5K (512 x 9 bits) — must be identical
• Function: Asynchronous FIFO operation — must be identical
• Bus configuration: Uni-Directional — must be identical
• Package type: 28-DIP (0.300", 7.62mm) — must be identical
• Voltage supply range: 4.5V ~ 5.5V — must be compatible
• Operating temperature range: 0°C ~ 70°C — must be compatible or exceed
• Mounting type: Through Hole — must be identical

The 7201LA12TPG meets all substitution criteria. This part shares identical memory capacity, asynchronous function, uni-directional bus configuration, package form factor, voltage supply range, operating temperature range, and through-hole mounting type. The substitute part offers improved electrical performance characteristics (12ns access time, 50MHz data rate) while maintaining full functional and physical compatibility.

Parameter Comparison

• Identical voltage supply range and operating temperature range ensure seamless integration into existing designs

Selection of the 7201LA12TPG is appropriate for new designs, system upgrades, and legacy equipment maintenance where component availability is a concern.

Frequently Asked Questions (FAQ)

Q: Can the 7201LA12TPG be used as a direct replacement for the 7201LA35TP?

A: Yes. Both parts share identical memory capacity (512 x 9), asynchronous function, uni-directional bus configuration, 28-DIP package form factor, voltage supply range (4.5V ~ 5.5V), and operating temperature range (0°C ~ 70°C). The parts are pin-compatible and functionally interchangeable.

Q: What are the key differences between these parts?

A: The primary differences are access time (35ns versus 12ns) and data rate (22.2MHz versus 50MHz). The 7201LA12TPG provides faster performance. Additionally, the 7201LA12TPG is an active product with ROHS3 compliance, while the 7201LA35TP is obsolete and RoHS non-compliant.

Q: Are there any package or mounting differences?

A: No. Both parts use the 28-DIP (0.300", 7.62mm) package with through-hole mounting. Physical dimensions and pinout are identical.

Q: Does the faster access time of the 7201LA12TPG affect circuit design?

A: The 7201LA12TPG's faster access time (12ns) is a performance enhancement. Circuits designed for the 7201LA35TP (35ns) will operate correctly with the substitute part. No circuit modifications are required.

Q: What is the significance of the RoHS compliance difference?

A: The 7201LA12TPG is ROHS3 compliant, meeting current environmental and regulatory standards for electronic components. The 7201LA35TP is RoHS non-compliant. For applications subject to RoHS requirements, the 7201LA12TPG is the appropriate selection.

Q: Is the 7201LA12TPG available in the same packaging format?

A: The 7201LA12TPG is supplied in tube packaging, while the 7201LA35TP packaging format is not specified in the provided data. Both parts use the identical 28-DIP package case. Tube packaging is a standard distribution format for through-hole components and does not affect component functionality or compatibility.
