Equivalent & Substitute Parts for 7204L20TP

Part Overview

The 7204L20TP, manufactured by Renesas Electronics Corporation, is an asynchronous FIFO logic IC with a memory size of 36K (4K x 9), uni-directional data flow, and a maximum data rate of 33.3MHz. It is housed in a 28-DIP (0.300", 7.62mm) through-hole package and operates with a typical access time of 20ns. The part is now classified as obsolete, increasing the need to identify suitable equivalent or substitute models to support system maintenance and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified based on equivalence in the following strictly defined parameters: memory size, function, data rate, access time, voltage and current supply ranges, data bus directionality, package and mounting type, and operating temperature. Substitution is allowed only when these parameters match or exceed the original part's specification within the original mechanical and environmental footprint.

Parameter Comparison

Engineering Selection Recommendations

The 7204L12TPG serves as a direct substitute for the 7204L20TP, offering identical or superior operating parameters within the same electrical and mechanical constraints. The substitute part maintains all critical specification compatibilities, including voltage range, current consumption, memory size, access time, data rate, temperature range, and package form factor. The 7204L12TPG provides enhanced compliance characteristics, possessing ROHS3 compliant status, while also being active in the manufacturer's catalog.

Frequently Asked Questions (FAQ)

Q1: What are the critical factors in substituting the 7204L20TP?
A1: Substitute parts must match the memory size, function (asynchronous FIFO), data bus configuration, operating voltage, maximum current, package type, and operating temperature. Data rate and access time equal to or better than the original are also required.

Q2: Is the 7204L12TPG mechanically compatible with the 7204L20TP?
A2: Yes, both devices use the same 28-DIP (0.300", 7.62mm) through-hole package and have identical mounting footprints.

Q3: Does substituting with the 7204L12TPG affect electrical performance in systems designed for the 7204L20TP?
A3: The 7204L12TPG meets or exceeds the electrical performance criteria specified for the 7204L20TP across all provided parameters.

Q4: What certifications or compliance differences exist between these parts?
A4: The 7204L20TP is RoHS non-compliant, while the 7204L12TPG is ROHS3 compliant.

Q5: Why is it necessary to identify an equivalent or substitute for the 7204L20TP?
A5: The 7204L20TP is listed as obsolete, requiring an alternative to maintain hardware lifecycle and supply chain continuity.

Q6: Are programmable or flag functions part of substitution considerations?
A6: Both parts are asynchronous FIFOs without programmable flag support, and these attributes are aligned between main and substitute parts per provided data.
