7202LA35TP Equivalent & Substitute Parts

Part Overview

The 7202LA35TP is an asynchronous FIFO (First-In-First-Out) memory IC manufactured by Renesas Electronics Corporation. This device provides 9K (1K x 9) storage capacity with a 35ns access time and operates at 22.2MHz data rate. The part is classified as obsolete, indicating it has been discontinued by the manufacturer. Finding equivalent or substitute components is necessary due to limited availability and the transition to active product lines that offer improved performance characteristics while maintaining core functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7202LA35TP is determined by the following critical parameters that must remain constant or be compatible:

• Memory Configuration: 9K (1K x 9) capacity must be maintained
• Function Type: Asynchronous FIFO operation required
• Bus Architecture: Uni-directional data flow
• Package Form Factor: 28-DIP (0.300", 7.62mm) for mechanical and electrical pin compatibility
• Supply Voltage Range: 4.5 V ~ 5.5 V compatibility
• Operating Temperature Range: 0°C ~ 70°C minimum requirement
• Mounting Type: Through-hole technology

The 7202LA12TPG qualifies as a direct substitute because it maintains identical memory configuration, function type, bus architecture, package form factor, supply voltage range, and operating temperature range. Performance parameters (access time and data rate) are improved in the substitute part, which is acceptable in substitution scenarios where the original specification represents a minimum requirement rather than a maximum constraint.

Parameter Comparison

Engineering Selection Recommendations

The 7202LA12TPG is the qualified substitute for the 7202LA35TP based on the following engineering criteria:

Functional Compatibility: Both devices maintain identical memory architecture (9K, 1K x 9), asynchronous FIFO operation, uni-directional bus configuration, and 28-DIP package form factor. Pin-to-pin compatibility is assured for direct board-level replacement.

Performance Enhancement: The substitute part provides superior access time (12ns versus 35ns) and higher data rate capability (50MHz versus 22.2MHz). These improvements are backward-compatible with applications designed for the original part, as the substitute meets or exceeds all timing requirements.

Compliance Status: The 7202LA12TPG holds Active product status with ROHS3 compliance, whereas the 7202LA35TP is Obsolete and RoHS non-compliant. Selection of the substitute part ensures long-term supply availability and regulatory compliance for new designs or production continuations.

Supply Voltage and Current: Both parts operate within the identical 4.5 V ~ 5.5 V supply range with 80mA maximum supply current, ensuring no modifications to power distribution circuitry are required.

Frequently Asked Questions (FAQ)

Q: Can the 7202LA12TPG directly replace the 7202LA35TP on existing circuit boards?

A: Yes. Both devices use the 28-DIP package with identical pin assignments. The substitute part is pin-compatible and requires no circuit modifications for direct board-level replacement.

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

A: The primary differences are access time (12ns versus 35ns) and data rate (50MHz versus 22.2MHz). The 7202LA12TPG offers faster performance. Additionally, the substitute part is Active status with ROHS3 compliance, while the original is Obsolete and RoHS non-compliant.

Q: Will the faster access time of the 7202LA12TPG cause compatibility issues?

A: No. Faster access time is a performance improvement that is backward-compatible. Applications designed for 35ns access time will operate correctly with a 12ns device, as the substitute meets the original timing requirement with margin.

Q: Are the memory configurations identical?

A: Yes. Both parts provide 9K (1K x 9) asynchronous FIFO memory with uni-directional bus architecture. Memory organization and functional behavior are identical.

Q: What is the operating temperature range for both parts?

A: Both the 7202LA35TP and 7202LA12TPG operate across 0°C to 70°C. Temperature range specifications are identical.

Q: Why is the 7202LA35TP listed as Obsolete?

A: The 7202LA35TP has been discontinued by Renesas Electronics Corporation. The 7202LA12TPG represents the active product line continuation with improved performance characteristics and modern compliance certifications.

Q: Are there any supply voltage differences?

A: No. Both devices require 4.5 V to 5.5 V supply voltage. Power supply design remains unchanged when substituting these parts.
