Renesas 7200L20TP Asynchronous FIFO Logic IC - Equivalent & Substitute Parts

Part Overview

The Renesas 7200L20TP is an asynchronous FIFO (First-In-First-Out) memory circuit with 2.25K capacity (256 x 9 bits) designed for uni-directional data buffering applications. This 28-PDIP through-hole component operates at 33.3MHz with a 20ns access time and is rated for 0°C to 70°C operating temperature range. The 7200L20TP is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support, maintenance, and new production runs where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7200L20TP is determined by strict alignment of the following critical parameters:

• Memory capacity: 2.25K (256 x 9) configuration
• FIFO function: Asynchronous operation
• Bus architecture: Uni-Directional data flow
• Package format: 28-PDIP through-hole mounting
• Voltage specification: 4.5V ~ 5.5V supply range
• Operating temperature range: 0°C ~ 70°C
• Current consumption: Maximum 80mA

The 7200L12TPG meets all substitution criteria. While this part exhibits improved electrical performance (12ns access time, 50MHz data rate), it maintains full compatibility with the 7200L20TP across all mechanical and functional parameters. The faster access time and higher data rate of the 7200L12TPG represent performance enhancements rather than functional deviations, making it a direct substitute suitable for applications requiring the 7200L20TP specification.

Parameter Comparison

Engineering Selection Recommendations

The 7200L12TPG is the qualified substitute for the obsolete 7200L20TP. Selection between these parts should be based on the following factors:

Product Status & Availability: The 7200L20TP is obsolete with limited remaining inventory (847 Pcs). The 7200L12TPG maintains active product status with higher inventory availability (1083 Pcs), ensuring long-term supply chain continuity.

Compliance & Certification: The 7200L12TPG achieves ROHS3 compliance, whereas the 7200L20TP is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the 7200L12TPG is the mandated choice.

Performance Characteristics: The 7200L12TPG provides superior electrical performance with 12ns access time and 50MHz data rate compared to the 7200L20TP specifications of 20ns and 33.3MHz. This performance improvement is backward-compatible and does not introduce functional incompatibility.

Mechanical & Electrical Compatibility: Both parts share identical package format (28-PDIP), voltage supply range (4.5V ~ 5.5V), current consumption (80mA maximum), and operating temperature range (0°C ~ 70°C), ensuring direct pin-for-pin substitution without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the 7200L12TPG directly replace the 7200L20TP without circuit modifications?

A: Yes. The 7200L12TPG is a direct pin-for-pin substitute. Both parts use identical 28-PDIP packaging, share the same voltage supply range (4.5V ~ 5.5V), and operate within the same temperature range (0°C ~ 70°C). No circuit redesign is required.

Q: What is the primary difference between the 7200L20TP and 7200L12TPG?

A: The 7200L12TPG offers improved electrical performance with 12ns access time and 50MHz data rate, compared to the 7200L20TP at 20ns and 33.3MHz. Both maintain identical memory capacity (2.25K), function (asynchronous), and bus architecture (uni-directional).

Q: Why is the 7200L20TP classified as obsolete?

A: The 7200L20TP is an older generation asynchronous FIFO logic IC. Renesas has transitioned this product to obsolete status, with the 7200L12TPG representing the current active equivalent offering improved performance and compliance characteristics.

Q: Does the 7200L12TPG meet RoHS requirements?

A: Yes. The 7200L12TPG is ROHS3 compliant. The 7200L20TP is RoHS non-compliant. For applications requiring RoHS compliance, the 7200L12TPG is the appropriate selection.

Q: Are there any current supply or thermal considerations when substituting these parts?

A: No. Both the 7200L20TP and 7200L12TPG are rated for maximum supply current of 80mA and operate across the identical 0°C to 70°C temperature range. Thermal and power supply design parameters remain unchanged.

Q: What packaging options are available for these parts?

A: Both parts are supplied in 28-PDIP (0.300", 7.62mm) through-hole package format. The 7200L12TPG is available in tube packaging. No surface-mount or alternative package variants are specified for these components.
