Renesas 72V01L35J Equivalent & Substitute Parts

Part Overview

The Renesas 72V01L35J is an asynchronous FIFO logic integrated circuit with 4.5K memory capacity (512 x 9 bits) designed for uni-directional data buffering applications. Operating at 22.2MHz with a 35ns access time, this component is housed in a 32-PLCC surface mount package and requires a 3V to 3.6V supply voltage.

The 72V01L35J has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 72V01L35J is determined by strict equivalence across the following critical parameters:

Memory Configuration: 4.5K (512 x 9) bits Function: Asynchronous FIFO operation Bus Architecture: Uni-Directional data flow Supply Voltage Range: 3V ~ 3.6V Package Type: 32-PLCC (14x11.46mm) Mounting: Surface Mount Operating Temperature Range: 0°C ~ 70°C

The 72V01L15JG qualifies as a direct substitute because it maintains identical memory capacity, function, bus directionality, voltage specifications, package configuration, and operating temperature range. Performance parameters (data rate and access time) are enhanced in the substitute part, which does not create incompatibility in applications designed for the original component.

Parameter Comparison

Engineering Selection Recommendations

The 72V01L15JG is the qualified substitute for the 72V01L35J based on the following engineering criteria:

Functional Equivalence: Both components provide identical asynchronous FIFO memory capacity, bus architecture, and electrical interface specifications.

Product Status Advantage: The 72V01L15JG maintains active product status with established supply chain availability, whereas the original part is obsolete.

Compliance Improvement: The substitute part achieves ROHS3 compliance, addressing regulatory requirements that the original non-compliant part does not satisfy.

Performance Enhancement: The 72V01L15JG delivers superior access time (15ns versus 35ns) and higher data rate capability (40MHz versus 22.2MHz), providing performance headroom without introducing incompatibility.

Packaging Compatibility: Identical 32-PLCC package footprint and surface mount configuration ensure direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 72V01L15JG be used as a direct replacement for the 72V01L35J in existing designs?

A: Yes. The substitute part maintains identical memory capacity, function, bus directionality, supply voltage range, package type, and operating temperature specifications. The enhanced performance parameters do not create incompatibility.

Q: What is the primary reason for substitution?

A: The 72V01L35J has reached obsolete status. The 72V01L15JG provides equivalent functionality with active product availability and improved compliance posture.

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

A: No. Both components operate within the 3V to 3.6V supply range, support identical uni-directional bus architecture, and maintain the same maximum supply current specification of 60mA.

Q: Does the package footprint differ between the original and substitute?

A: No. Both parts use the 32-PLCC (14x11.46mm) J-Lead package in surface mount configuration. No PCB layout modifications are required.

Q: What is the significance of the different access time specifications?

A: The 72V01L15JG provides faster access time (15ns) compared to the original part (35ns). This represents improved performance that does not degrade compatibility with designs specified for the slower original component.

Q: How do the RoHS compliance statuses differ?

A: The original 72V01L35J is RoHS non-compliant. The substitute 72V01L15JG achieves ROHS3 compliance, meeting current environmental and regulatory standards.

Q: What is the moisture sensitivity level difference?

A: The original part has MSL 1 (unlimited moisture exposure tolerance). The substitute has MSL 3 (168-hour moisture exposure limit). Standard moisture control procedures during storage and assembly are required for the substitute part.
