Equivalent & Substitute Parts for 7204L50TP

Part Overview

The 7204L50TP is an asynchronous FIFO (First-In-First-Out) memory IC manufactured by Renesas Electronics Corporation. This device provides 36K bits of storage (4K x 9 organization) with a 50ns access time and 15MHz data rate in a 28-pin DIP package. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. The 7204L50TP operates within the 4.5V to 5.5V supply range and is designed for uni-directional data flow applications requiring asynchronous FIFO functionality.

Substitute Part Grouping Explanation

Substitution of the 7204L50TP is determined by the following critical parameters that must remain constant or be compatible:

• Memory Organization: 36K (4K x 9) configuration
• FIFO Type: Asynchronous operation
• Bus Configuration: Uni-Directional data flow
• Package: 28-DIP form factor with 0.300" (7.62mm) pitch
• Voltage Supply Range: 4.5V ~ 5.5V compatibility
• Mounting: Through-hole technology
• Operating Temperature: 0°C ~ 70°C range

The 7204L12TPG qualifies as a direct substitute based on identical memory organization, FIFO architecture, bus configuration, package form factor, voltage supply range, and operating temperature specifications. The substitute part offers improved electrical performance characteristics while maintaining full pin and functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 7204L12TPG is a direct functional and physical substitute for the 7204L50TP. Selection between these parts is based on the following engineering considerations:

For 7204L50TP (Obsolete): This part is no longer in active production. Continued use is limited to existing inventory or legacy system maintenance where no design modifications are possible.

For 7204L12TPG (Active): This part is the recommended selection for all new designs and system upgrades. The 7204L12TPG maintains identical pin configuration, memory organization, and voltage specifications while providing superior electrical performance. The substitute operates at 50MHz data rate with 12ns access time, compared to the original 15MHz and 50ns specifications. The 7204L12TPG achieves ROHS3 compliance, meeting current environmental and regulatory standards, whereas the 7204L50TP is RoHS non-compliant.

Both parts share identical supply current specifications (120mA maximum), operating temperature range (0°C to 70°C), and through-hole 28-DIP packaging, ensuring direct board-level compatibility without circuit modifications.

Frequently Asked Questions (FAQ)

Q: Can the 7204L12TPG replace the 7204L50TP in existing designs?

A: Yes. The 7204L12TPG is a direct pin-for-pin and functional substitute. Both devices use identical 28-DIP packaging, operate within the same 4.5V to 5.5V supply range, and provide the same 4K x 9 asynchronous FIFO memory organization. No circuit modifications are required for substitution.

Q: What are the key differences between these parts?

A: The primary differences are access time (50ns vs. 12ns), data rate capability (15MHz vs. 50MHz), product status (obsolete vs. active), and RoHS compliance (non-compliant vs. ROHS3 compliant). The 7204L12TPG offers improved performance specifications and current regulatory compliance.

Q: Are there any compatibility concerns with the package?

A: No. Both parts use identical 28-DIP (0.300", 7.62mm) through-hole packaging. Board layouts, socket compatibility, and mechanical mounting are fully interchangeable.

Q: Why is the 7204L50TP classified as obsolete?

A: The 7204L50TP has been discontinued by Renesas Electronics Corporation. The 7204L12TPG represents the current production alternative within the 7200 series FIFO family.

Q: Does the faster access time of the 7204L12TPG affect system operation?

A: No negative effects occur. The 7204L12TPG's 12ns access time is faster than the original 50ns specification. Systems designed for the 7204L50TP will operate correctly with the faster substitute part.

Q: What is the significance of ROHS3 compliance?

A: ROHS3 compliance indicates the 7204L12TPG meets current European Union Restriction of Hazardous Substances regulations. This is required for new product designs and system certifications in most markets.
