IDT7204L12SO Equivalent & Substitute Parts

Part Overview

The IDT7204L12SO is an asynchronous FIFO (First-In-First-Out) memory IC manufactured by Renesas Electronics Corporation. This device provides 36K bits of storage (4K x 9 organization) with a 12-nanosecond access time and operates at data rates up to 50MHz. The component is housed in a 28-SOIC surface-mount package and is designed for uni-directional data buffering applications requiring depth and width expansion capabilities.

The IDT7204L12SO is classified as obsolete, which necessitates identification of equivalent substitute components for new designs or ongoing production requirements. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IDT7204L12SO is determined by strict equivalence across the following critical parameters:

• Memory organization (4K x 9 bits = 36K total)
• Asynchronous FIFO function
• Access time (12ns maximum)
• Data rate capability (50MHz minimum)
• Supply voltage range (4.5V ~ 5.5V)
• Package specification (28-SOIC)
• Uni-directional bus architecture
• Operating temperature range (0°C ~ 70°C)

The substitute part 7204L12SOG meets all electrical and mechanical requirements for direct substitution. The primary distinction between the main part and substitute is product status and compliance certification, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 7204L12SOG is the direct equivalent substitute for the IDT7204L12SO. Both components are manufactured by Renesas Electronics Corporation and share identical electrical specifications, memory organization, access timing, and package configuration.

The primary advantage of selecting 7204L12SOG is its active product status and ROHS3 compliance certification. The IDT7204L12SO, being obsolete and RoHS non-compliant, presents supply chain risk and regulatory constraints for new designs or production environments subject to RoHS requirements.

For applications where RoHS compliance is mandatory or where long-term component availability is critical, 7204L12SOG is the appropriate selection. The electrical and mechanical compatibility ensures direct substitution without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can 7204L12SOG be used as a direct replacement for IDT7204L12SO?

A: Yes. Both components are electrically and mechanically identical. The 28-SOIC package pinout, signal timing, voltage requirements, and current specifications are equivalent. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The IDT7204L12SO is obsolete, while 7204L12SOG is active. Additionally, 7204L12SOG carries ROHS3 compliance certification, whereas IDT7204L12SO is RoHS non-compliant. All functional and electrical parameters are identical.

Q: Are there any package or pinout differences?

A: No. Both components use the 28-SOIC (0.345", 8.77mm Width) surface-mount package. PCB footprints and component placement are identical.

Q: What is the moisture sensitivity level for these components?

A: Both the IDT7204L12SO and 7204L12SOG have a Moisture Sensitivity Level (MSL) of 3, with a floor life of 168 hours. Standard moisture control procedures during storage and handling apply.

Q: Are there supply voltage or current differences?

A: No. Both components operate within the 4.5V to 5.5V supply range and draw a maximum of 120mA. Power supply design and decoupling requirements are identical.

Q: Which part should be specified for new designs?

A: The 7204L12SOG should be specified for new designs due to its active product status and ROHS3 compliance. This ensures long-term availability and regulatory alignment.
