Equivalent & Substitute Parts for 7205L25TP

Part Overview

The 7205L25TP is an asynchronous FIFO (First-In-First-Out) memory IC manufactured by Renesas Electronics Corporation. This device provides 72K bits of storage (8K x 9 organization) with a 25ns access time and 28.5MHz data rate 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 7205L25TP operates within the 4.5V to 5.5V supply range and supports depth and width expansion capabilities for larger memory configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7205L25TP is determined by the following critical parameters:

• Memory organization (8K x 9 bits)
• Asynchronous FIFO function
• Uni-directional bus architecture
• 28-pin DIP package with 0.300" (7.62mm) pitch
• Through-hole mounting compatibility
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (0°C ~ 70°C)

The 7205L12TPG meets all these core requirements. While it offers improved performance characteristics (12ns access time and 50MHz data rate versus 25ns and 28.5MHz), these enhancements are backward-compatible with applications designed for the 7205L25TP. The identical memory organization, package footprint, and electrical interface ensure direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The 7205L12TPG is the direct substitute for the 7205L25TP. Selection of the 7205L12TPG is supported by the following factors:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance satisfies modern environmental and regulatory requirements, whereas the 7205L25TP is RoHS non-compliant
• Improved performance specifications (12ns access time, 50MHz data rate) provide operational headroom without requiring circuit redesign
• Identical package, pinout, and electrical interface enable direct board-level replacement
• Both devices maintain the same supply voltage range and maximum current specifications

Frequently Asked Questions (FAQ)

Q: Can the 7205L12TPG replace the 7205L25TP in existing designs?

A: Yes. The 7205L12TPG is a direct substitute. Both devices share identical memory organization (8K x 9), package configuration (28-DIP), pinout, supply voltage range (4.5V ~ 5.5V), and operating temperature range (0°C ~ 70°C). The faster access time and higher data rate of the 7205L12TPG are backward-compatible with applications designed for the 7205L25TP.

Q: What are the key differences between these parts?

A: The primary differences are access time (25ns versus 12ns), data rate (28.5MHz versus 50MHz), product status (obsolete versus active), and RoHS compliance (non-compliant versus ROHS3 compliant). The 7205L12TPG offers superior performance and regulatory compliance.

Q: Are the packages identical?

A: Yes. Both the 7205L25TP and 7205L12TPG use 28-pin DIP packages with 0.300" (7.62mm) pitch and through-hole mounting. No PCB layout modifications are required for substitution.

Q: Does the 7205L12TPG require different supply voltage?

A: No. Both parts operate within the same supply voltage range of 4.5V to 5.5V and draw a maximum of 120mA. Existing power supply designs require no modification.

Q: Why is the 7205L25TP listed as obsolete?

A: The 7205L25TP has been discontinued by Renesas Electronics Corporation. The 7205L12TPG represents the active product line continuation with improved specifications and regulatory compliance.
