Equivalent & Substitute Parts for Renesas 7204L12PI

Part Overview

The Renesas 7204L12PI is an asynchronous FIFO (First-In-First-Out) memory circuit with 4K x 9 bit capacity, designed for high-speed data buffering applications. This device operates at 50MHz with a 12-nanosecond access time and is housed in a 28-pin DIP package for through-hole mounting.

The 7204L12PI carries an obsolete product status. Locating equivalent substitute components is necessary to support legacy system maintenance, repair, and continued operation where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7204L12PI is determined by the following core parameters:

Critical Matching Parameters:

• Memory capacity: 4K x 9 bits
• Function: Asynchronous FIFO operation
• Data rate: 50MHz minimum
• Access time: 12ns maximum
• Supply voltage: 4.5V to 5.5V compatibility
• Bus directional: Uni-Directional
• Retransmit capability: Yes
• Programmable flags: No
• FWFT support: No

The 7204L12JG qualifies as a functional substitute because it maintains identical electrical specifications across all critical parameters. The primary difference is packaging format: the substitute uses 32-pin PLCC surface-mount technology instead of 28-pin DIP through-hole mounting. This packaging change requires circuit board redesign and assembly process modification but does not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 7204L12JG is electrically and functionally equivalent to the 7204L12PI across all core FIFO specifications. Selection of this substitute requires evaluation of the following factors:

Packaging Compatibility: The substitute uses 32-pin PLCC surface-mount packaging versus the original 28-pin DIP through-hole format. Circuit board layout and assembly process must be modified to accommodate this change. Pin-to-pin functional mapping must be verified against device datasheets before implementation.

Operating Temperature Range: The substitute operates over 0°C to 70°C, which is narrower than the original -40°C to 85°C range. Applications requiring extended temperature operation below 0°C or above 70°C cannot use this substitute without thermal management verification.

Product Status and Availability: The 7204L12JG maintains active product status with documented inventory availability, ensuring long-term supply continuity compared to the obsolete 7204L12PI.

Compliance and Certifications: The 7204L12JG is RoHS3 compliant and REACH unaffected, meeting modern regulatory requirements for new designs and system updates.

Frequently Asked Questions (FAQ)

Q: Can the 7204L12JG directly replace the 7204L12PI in existing circuit boards?

A: No. The 7204L12JG uses 32-pin PLCC surface-mount packaging while the 7204L12PI uses 28-pin DIP through-hole packaging. Direct socket replacement is not possible. Circuit board redesign and component footprint modification are required.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both devices share identical memory capacity (4K x 9), data rate (50MHz), access time (12ns), supply voltage (4.5V to 5.5V), and maximum current (120mA). All FIFO functional characteristics match exactly.

Q: What is the temperature operating range difference?

A: The 7204L12PI operates from -40°C to 85°C, while the 7204L12JG operates from 0°C to 70°C. The substitute has a narrower temperature range. Applications requiring operation below 0°C or above 70°C must use the original part or identify alternative solutions.

Q: Is the 7204L12JG suitable for new product designs?

A: Yes. The 7204L12JG carries active product status and meets current RoHS3 compliance requirements, making it appropriate for new designs. The 7204L12PI is obsolete and should not be specified for new applications.

Q: What pin count difference exists between these devices?

A: The 7204L12PI uses 28 pins in DIP configuration. The 7204L12JG uses 32 pins in PLCC configuration. Pin assignments must be cross-referenced with manufacturer datasheets to ensure correct signal routing.

Q: Can both parts be used interchangeably in the same system?

A: No. While electrically equivalent, the different packaging formats prevent interchangeable use without circuit board modification. System designs must standardize on one package type.
