Equivalent & Substitute Parts for 7201LA50TP

Part Overview

The 7201LA50TP is an asynchronous FIFO (First-In-First-Out) memory circuit manufactured by Renesas Electronics Corporation. This 512 x 9-bit uni-directional FIFO operates at 15MHz with a 50ns access time and is housed in a 28-pin DIP package. The device is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. The 7200 series architecture provides depth and width expansion capabilities for applications requiring larger memory buffers or parallel data handling.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201LA50TP is determined by strict compatibility across the following critical parameters:

Memory Architecture: The substitute must maintain identical memory size (4.5K / 512 x 9) and asynchronous FIFO function to ensure pin-level and functional compatibility.

Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), maximum supply current (80mA), and uni-directional bus configuration must remain unchanged to prevent circuit redesign.

Physical Package: The 28-DIP package with 0.300" (7.62mm) pitch is mandatory for direct board-level replacement without PCB modification.

Operating Environment: Temperature range (0°C ~ 70°C) must be maintained for application compatibility.

The 7201LA12TPG qualifies as a direct substitute because it maintains all mandatory parameters while offering improved performance characteristics (12ns access time, 50MHz data rate) and active product status with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The 7201LA12TPG is the qualified substitute for the 7201LA50TP based on the following engineering criteria:

Functional Compatibility: Both devices share identical memory architecture (512 x 9 asynchronous FIFO), electrical specifications (4.5V ~ 5.5V supply, 80mA maximum current), and physical packaging (28-DIP through-hole). No circuit redesign is required for direct substitution.

Product Availability: The 7201LA50TP is classified as obsolete, while the 7201LA12TPG maintains active product status with confirmed inventory availability. This ensures long-term supply chain reliability and component sourcing for production and field replacement applications.

Regulatory Compliance: The 7201LA12TPG achieves RoHS3 compliance, meeting current environmental and regulatory requirements for new designs and manufacturing processes. The original 7201LA50TP is RoHS non-compliant, making the substitute the appropriate choice for compliant system implementations.

Performance Enhancement: The substitute provides superior performance with 12ns access time and 50MHz data rate compared to the original 50ns / 15MHz specification. These improvements are backward-compatible and do not introduce timing conflicts in systems designed for the original part's specifications.

Frequently Asked Questions (FAQ)

Q: Can the 7201LA12TPG directly replace the 7201LA50TP without PCB modification?

A: Yes. Both devices use identical 28-DIP packaging with 0.300" (7.62mm) pitch and maintain the same pin configuration for asynchronous FIFO operation. Direct board-level substitution is possible without PCB redesign.

Q: Are the electrical specifications compatible between these parts?

A: Yes. Both devices operate within the 4.5V ~ 5.5V supply voltage range, draw a maximum of 80mA supply current, and maintain the same operating temperature range (0°C ~ 70°C). No power supply or thermal management modifications are required.

Q: What is the significance of the improved access time and data rate in the substitute?

A: The 7201LA12TPG offers 12ns access time and 50MHz data rate compared to the 7201LA50TP's 50ns and 15MHz. These improvements provide faster memory operations and higher throughput capability. Systems designed for the original part will operate correctly with the faster substitute, as timing requirements are met or exceeded.

Q: Why is RoHS3 compliance important for the substitute?

A: RoHS3 compliance indicates the 7201LA12TPG meets current environmental and regulatory standards for hazardous substance restrictions. For new designs and manufacturing processes subject to RoHS requirements, the substitute is the appropriate choice. The original 7201LA50TP's non-compliance status makes it unsuitable for regulated applications.

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

A: Yes. The substitute is supplied in 28-PDIP packaging (equivalent to 28-DIP), maintaining physical and electrical compatibility with the original part's through-hole mounting requirements.
