7202LA12J Equivalent & Substitute Parts

Part Overview

The 7202LA12J 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 12ns access time and operates at 50MHz, housed in a 32-PLCC surface mount package. The 7202LA12J is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7202LA12J is determined by strict equivalence across the following critical parameters:

• Memory configuration: 9K (1K x 9) capacity
• Asynchronous FIFO function with uni-directional bus architecture
• Electrical specifications: 50MHz data rate, 12ns access time, 4.5 V ~ 5.5 V supply voltage, 80mA maximum supply current
• Physical package: 32-PLCC (14x11.46mm) surface mount configuration
• Operating temperature range: 0°C ~ 70°C

The 7202LA12JG meets all these criteria and is therefore a direct functional equivalent. Substitution is valid only when all parameters match exactly.

Parameter Comparison

Engineering Selection Recommendations

The 7202LA12JG is the direct substitute for the obsolete 7202LA12J. Both parts are manufactured by Renesas Electronics Corporation and share identical electrical and mechanical specifications across all functional parameters.

The 7202LA12JG offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the 7202LA12JG meets ROHS3 compliance requirements, whereas the 7202LA12J is RoHS non-compliant. This distinction is significant for applications subject to environmental regulations or customer compliance mandates.

The MSL (Moisture Sensitivity Level) difference between the parts reflects standard manufacturing practices for active versus obsolete product lines and does not affect functional compatibility in standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can the 7202LA12JG be used as a direct replacement for the 7202LA12J?

A: Yes. The 7202LA12JG is electrically and mechanically equivalent to the 7202LA12J. All functional parameters, including memory capacity, access time, data rate, supply voltage, and package configuration, are identical.

Q: What is the primary reason to transition from 7202LA12J to 7202LA12JG?

A: The 7202LA12J is classified as obsolete, creating supply chain risk. The 7202LA12JG is an active product with ongoing manufacturing support and availability. Additionally, the 7202LA12JG meets ROHS3 compliance standards.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts operate at 50MHz with 12ns access time, support 4.5 V ~ 5.5 V supply voltage, and draw a maximum of 80mA. Electrical performance is identical.

Q: Do these parts use the same package and pinout?

A: Yes. Both parts use the 32-PLCC (14x11.46mm) surface mount package with J-lead configuration. Pinout and footprint compatibility are confirmed.

Q: What is the difference in MSL rating between these parts?

A: The 7202LA12J has MSL 1 (unlimited moisture exposure tolerance), while the 7202LA12JG has MSL 3 (168-hour moisture exposure tolerance). This reflects standard moisture sensitivity classifications for active products and does not affect performance in typical operating conditions.
