IDT7202LA12SO Equivalent & Substitute Parts

Part Overview

The IDT7202LA12SO is an asynchronous FIFO (First-In-First-Out) memory circuit manufactured by Renesas Electronics Corporation. This device provides 9K (1K x 9) storage capacity with a 12ns access time and operates at 50MHz data rate. The component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and production requirements. Substitute parts must maintain identical electrical specifications and package compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IDT7202LA12SO is determined by strict equivalence across the following critical parameters:

• Memory architecture: 9K (1K x 9) configuration
• FIFO operation mode: Asynchronous function
• Performance specifications: 50MHz data rate and 12ns access time
• Electrical characteristics: 4.5 V ~ 5.5 V supply voltage and 80mA maximum current
• Physical form factor: 28-SOIC surface mount package
• Thermal operating range: 0°C ~ 70°C

The substitute part 7202LA12SOG meets all these criteria and is manufactured by the same supplier (Renesas Electronics Corporation) within the same 7200 series product line. The primary distinction between the main part and substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 7202LA12SOG is the direct functional equivalent of the IDT7202LA12SO. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional interchangeability in circuit applications.
