7201LA20TP Equivalent & Substitute Parts

Part Overview

The 7201LA20TP 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 20ns access time and 33.3MHz data rate, housed 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 7201LA20TP 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
• Voltage Supply Range: 4.5V ~ 5.5V (fully compatible)
• Current Supply: 80mA maximum (identical specification)
• Operating Temperature Range: 0°C ~ 70°C (identical range)
• Mounting Type: Through Hole (identical)

The 7201LA12TPG represents an enhanced version within the same product family (7200 series), offering superior performance characteristics while maintaining complete electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 7201LA12TPG is the appropriate substitute for the 7201LA20TP based on the following factors:

Product Status: The 7201LA20TP is classified as obsolete, while the 7201LA12TPG maintains active product status with confirmed inventory availability (1035 pcs in stock versus 968 pcs for the obsolete part). Active status ensures continued supply chain access and manufacturing support.

Compliance and Certifications: The 7201LA12TPG achieves ROHS3 compliance, whereas the 7201LA20TP is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 ECCN classification. The substitute's improved compliance posture aligns with current regulatory requirements for electronic components.

Performance Enhancement: The 7201LA12TPG delivers superior performance with 12ns access time and 50MHz data rate compared to the 7201LA20TP's 20ns access time and 33.3MHz data rate. This performance improvement is backward-compatible with applications designed for the original part.

Electrical and Mechanical Compatibility: All critical parameters remain identical, including supply voltage range, maximum current draw, package dimensions, and operating temperature range. Direct pin-for-pin compatibility is maintained.

Frequently Asked Questions (FAQ)

Q: Can the 7201LA12TPG be used as a direct replacement for the 7201LA20TP in existing designs?

A: Yes. The 7201LA12TPG maintains identical pinout, package dimensions (28-DIP), supply voltage range (4.5V ~ 5.5V), and maximum current specifications (80mA). No circuit modifications are required for substitution.

Q: What are the key differences between these two parts?

A: The primary differences are access time (20ns versus 12ns), data rate (33.3MHz versus 50MHz), product status (obsolete versus active), and RoHS compliance (non-compliant versus ROHS3 compliant). The substitute offers improved performance and regulatory compliance.

Q: Are there any compatibility concerns with the 28-DIP package?

A: No. Both parts use identical 28-DIP (0.300", 7.62mm) packaging with through-hole mounting. PCB layouts and socket compatibility remain unchanged.

Q: Why is the 7201LA20TP classified as obsolete?

A: The 7201LA20TP has reached end-of-life status within Renesas Electronics' product portfolio. The 7201LA12TPG represents the current active alternative within the 7200 series FIFO family.

Q: Does the faster access time of the 7201LA12TPG affect system compatibility?

A: No. Faster access time is a performance enhancement that maintains backward compatibility. Systems designed for 20ns access time operate correctly with 12ns access time components.

Q: What is the significance of ROHS3 compliance on the 7201LA12TPG?

A: ROHS3 compliance indicates the substitute meets current European Union Restriction of Hazardous Substances regulations. This is relevant for applications subject to RoHS requirements or for future-proofing designs against regulatory changes.
