THS3201D Equivalent & Substitute Parts

Part Overview

The THS3201D is a current feedback amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as "Not For New Designs," indicating it has reached end-of-life status. The THS3201D delivers high-speed amplification with a slew rate of 9800V/µs and -3dB bandwidth of 1.8 GHz, making it suitable for applications requiring ultra-fast signal processing. Due to its obsolescence status, identifying equivalent and substitute parts is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the THS3201D is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier Type: Current Feedback (mandatory match)
• Number of Circuits: 1 (mandatory match)
• Package / Case: 8-SOIC surface mount (mandatory match)
• Operating Temperature Range: -40°C to 85°C (mandatory match)
• Mounting Type: Surface Mount (mandatory match)

Secondary Compatibility Parameters:

• Slew Rate: Must equal or exceed 9800V/µs for performance equivalence
• -3dB Bandwidth: Must equal or exceed 1.8 GHz for performance equivalence
• Voltage - Supply Span: Must accommodate the 6.6V to 15V range
• Current - Supply: Operating current consumption
• Current - Output / Channel: Output drive capability

The substitute parts identified (AD8007ARZ-R7 and THS3001ID) share the identical package, mounting type, and circuit topology. However, they exhibit different performance characteristics in slew rate and bandwidth, which affects their suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

AD8007ARZ-R7 (Analog Devices Inc.)

The AD8007ARZ-R7 is the only substitute part with Active product status, making it the preferred choice for new procurement and long-term supply chain stability. This device is ROHS3 compliant and carries unlimited moisture sensitivity rating. However, the AD8007ARZ-R7 exhibits reduced performance specifications compared to the THS3201D: slew rate of 1000V/µs (versus 9800V/µs) and -3dB bandwidth of 650 MHz (versus 1.8 GHz). The maximum supply voltage is limited to 12V, which falls below the THS3201D's 15V maximum. The AD8007ARZ-R7 is suitable for applications where the lower bandwidth and slew rate are acceptable within the circuit design constraints.

THS3001ID (Texas Instruments)

The THS3001ID carries Obsolete product status, indicating it is no longer manufactured or supported. This part is not recommended for new designs or long-term applications. While it maintains the same 8-SOIC package and surface mount configuration, its obsolescence status creates procurement and supply chain risk. The THS3001ID offers a wider supply voltage range (9V to 33V maximum) but delivers intermediate performance between the THS3201D and AD8007ARZ-R7, with slew rate of 6500V/µs and -3dB bandwidth of 420 MHz.

Compliance and Certification

All three parts (THS3201D, AD8007ARZ-R7, and THS3001ID) are ROHS3 compliant, REACH unaffected, and carry ECCN classification EAR99. All parts maintain MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the AD8007ARZ-R7 directly replace the THS3201D in existing designs?

A: Direct replacement depends on application-specific bandwidth and slew rate requirements. The AD8007ARZ-R7 operates at 1000V/µs slew rate and 650 MHz bandwidth, both significantly lower than the THS3201D's 9800V/µs and 1.8 GHz specifications. Circuit redesign and performance validation are necessary if the original design relies on the THS3201D's high-speed characteristics.

Q: Why is the THS3001ID listed as a substitute if it is obsolete?

A: The THS3001ID is included in the substitute list based on the provided input parameters, which identify it as a related part. However, its Obsolete status makes it unsuitable for new applications or long-term procurement. Existing inventory may be available, but supply continuity cannot be assured.

Q: Are all three parts pin-compatible?

A: All three parts share the 8-SOIC package configuration with identical physical dimensions (0.154" width, 3.90mm). Pin compatibility for the 8-SOIC package is standard across these current feedback amplifier designs. However, electrical performance differences require circuit validation before substitution.

Q: What is the supply voltage compatibility between these parts?

A: The THS3201D operates from 6.6V to 15V. The AD8007ARZ-R7 operates from 5V to 12V, which overlaps the lower range but does not support the full 15V maximum of the THS3201D. The THS3001ID operates from 9V to 33V, supporting higher voltages but requiring minimum 9V supply. Circuit power supply design must accommodate these differences.

Q: Which substitute part offers the best long-term availability?

A: The AD8007ARZ-R7 is the only part with Active product status, indicating ongoing manufacture and support by Analog Devices Inc. This status provides the most reliable long-term availability and supply chain continuity for new designs and future procurement.

Q: Are there any packaging or handling differences between these parts?

A: The THS3201D is supplied in Tube packaging, while the AD8007ARZ-R7 is supplied in Cut Tape (CT) and Digi-Reel® packaging. The THS3001ID is supplied in Tube packaging. All parts carry MSL rating 1 (Unlimited), indicating identical moisture sensitivity handling requirements. Packaging format does not affect electrical performance or pin compatibility.
