TL592B-8DR Equivalent & Substitute Parts

Part Overview

The TL592B-8DR is a differential video amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This linear amplifier is designed for differential signal processing applications with a -3dB bandwidth of 50 MHz. The device operates on a dual supply voltage range of ±3V to ±8V and draws 18 mA supply current with 4 mA output current per channel.

The TL592B-8DR is classified as Last Time Buy, indicating discontinued production. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and field support requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TL592B-8DR is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Output Type: Differential
• Number of Circuits: 1
• Voltage - Supply, Single/Dual (±): ±3V ~ 8V
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Parameter Variations:

• Current - Supply: Equal or greater capacity acceptable
• Current - Output / Channel: Equal or greater capacity acceptable
• -3dB Bandwidth: Equal or greater performance acceptable
• Product Status: Active status preferred for long-term availability
• Applications: May differ (General Purpose vs. Differential) provided electrical specifications remain compatible

The NE592D8R2G from onsemi meets all mandatory matching parameters and demonstrates acceptable variations in current specifications, making it a valid substitute for the TL592B-8DR.

Parameter Comparison

Engineering Selection Recommendations

The NE592D8R2G is a qualified substitute for the TL592B-8DR based on the following engineering criteria:

Electrical Compatibility: Both devices operate within identical supply voltage ranges (±3V to ±8V) and share identical supply current specifications (18 mA). The NE592D8R2G provides higher output current per channel (10 mA vs. 4 mA), which represents a performance enhancement rather than a limitation. Both devices maintain differential output configuration with single circuit topology.

Package and Mechanical Compatibility: Both parts utilize the 8-SOIC package with identical physical dimensions (0.154", 3.90mm width), ensuring direct PCB footprint compatibility and surface mount assembly compatibility without design modification.

Compliance and Regulatory Status: Both devices maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, satisfying identical regulatory and environmental requirements.

Availability Advantage: The NE592D8R2G carries Active product status with 25,100 units in stock, compared to the TL592B-8DR Last Time Buy status with 7,392 units. This substitution provides extended component availability for production continuity.

Frequently Asked Questions (FAQ)

Q: Can the NE592D8R2G directly replace the TL592B-8DR without PCB modifications?

A: Yes. Both devices share identical 8-SOIC package dimensions and pinout compatibility. No PCB layout changes are required for mechanical or electrical integration.

Q: What is the significance of the higher output current specification in the NE592D8R2G?

A: The NE592D8R2G provides 10 mA output current per channel versus 4 mA in the TL592B-8DR. This represents increased output drive capability and is compatible with designs specified for the lower current device. No circuit redesign is necessary.

Q: Are there differences in bandwidth performance between these devices?

A: The TL592B-8DR specifies -3dB bandwidth of 50 MHz. The NE592D8R2G bandwidth specification was not provided in the available parameters. Bandwidth compatibility must be verified against specific application requirements if this parameter is critical to system performance.

Q: Why is product status relevant to component selection?

A: The TL592B-8DR is Last Time Buy, indicating production discontinuation. The NE592D8R2G Active status ensures continued manufacturing and long-term supply availability, reducing obsolescence risk for ongoing production requirements.

Q: Do both devices meet the same regulatory compliance standards?

A: Yes. Both the TL592B-8DR and NE592D8R2G are ROHS3 compliant and carry MSL Level 1 (Unlimited) ratings, satisfying identical environmental and regulatory requirements.

Q: What packaging formats are available for the NE592D8R2G?

A: The NE592D8R2G is supplied in Tape & Reel (TR) format. The TL592B-8DR is available in Cut Tape (CT) and Digi-Reel® formats. Verify packaging format compatibility with your procurement and assembly processes.
