Equivalent & Substitute Parts for 7205L35TP

Part Overview

The 7205L35TP 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 35ns access time and operates at 22.22MHz 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 7205L35TP is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. Substitute parts must maintain functional compatibility while meeting current compliance and availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7205L35TP 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, 50MHz data rate), it maintains full functional and physical compatibility with the 7205L35TP. The substitute part operates within the same voltage and temperature specifications and uses identical packaging, enabling direct replacement in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The 7205L12TPG is a direct functional substitute for the 7205L35TP. Both parts share identical memory organization, bus architecture, and physical packaging. The 7205L12TPG is currently in active product status, ensuring availability and ongoing manufacturer support, whereas the 7205L35TP is obsolete.

The 7205L12TPG demonstrates superior performance with a 12ns access time and 50MHz data rate compared to the 7205L35TP's 35ns and 22.22MHz specifications. This performance improvement is backward-compatible with legacy designs, as the substitute part can operate at the slower speeds required by existing circuits.

From a compliance perspective, the 7205L12TPG is RoHS3 compliant, whereas the 7205L35TP is RoHS non-compliant. Both parts are REACH unaffected and classified under ECCN EAR99. Selection should prioritize the 7205L12TPG for new inventory acquisition and system maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the 7205L12TPG directly replace the 7205L35TP in existing circuit designs?

A: Yes. Both parts are 28-pin DIP packages with identical pinouts, memory organization (8K x 9), and electrical specifications (4.5V ~ 5.5V supply, 0°C ~ 70°C operating range). The 7205L12TPG's faster access time and higher data rate are backward-compatible with designs specified for the 7205L35TP.

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

A: The primary differences are access time (35ns vs. 12ns) and data rate (22.22MHz vs. 50MHz). The 7205L12TPG also offers improved compliance status (RoHS3 compliant vs. RoHS non-compliant). Both parts maintain identical memory capacity, bus architecture, and package specifications.

Q: Why is the 7205L35TP listed as obsolete?

A: The 7205L35TP has reached end-of-life status with Renesas Electronics Corporation. The 7205L12TPG represents the current active product offering in this FIFO family, providing superior performance and modern compliance certifications.

Q: Are there any thermal or power consumption differences?

A: Both parts specify a maximum supply current of 120mA and operate within the same temperature range (0°C ~ 70°C). No thermal or power consumption differences are documented between these devices.

Q: What packaging options are available for the 7205L12TPG?

A: The 7205L12TPG is supplied in tube packaging. Both parts use the 28-PDIP package format with through-hole mounting, maintaining mechanical compatibility for PCB assembly.
