THS3201DBVRG4 Equivalent & Substitute Parts

Part Overview

The THS3201DBVRG4 is a Current Feedback Amplifier integrated circuit manufactured by Texas Instruments, housed in a SOT-23-5 surface mount package. This single-circuit operational amplifier is designed for high-speed signal processing applications requiring wide bandwidth and fast slew rate performance.

The THS3201DBVRG4 is currently discontinued at DiGi Electronics. Locating equivalent or substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements. Alternative parts must maintain electrical compatibility across critical performance parameters while accommodating available packaging and inventory options.

Substitute Part Grouping Explanation

Substitute parts for the THS3201DBVRG4 are identified based on strict electrical and mechanical compatibility criteria. The substitution logic is organized into two categories:

Category 1: Direct Electrical Equivalents (Same Package) Parts that maintain identical or equivalent electrical performance within the same SOT-23-5 package form factor. These parts preserve pin compatibility and circuit board layout without modification.

Category 2: Functional Equivalents (Different Package) Parts that deliver equivalent electrical performance but utilize different package configurations. These substitutes require circuit board redesign and layout changes but provide access to active inventory and alternative supply chain options.

Key Parameters Determining Substitutability:

• Amplifier Type: Current Feedback (required)
• Number of Circuits: 1 (required)
• Operating Temperature Range: -40°C to 85°C (required)
• Slew Rate: 9800 V/µs or higher (performance criterion)
• -3dB Bandwidth: 1.8 GHz or higher (performance criterion)
• Supply Voltage Range: Compatibility with 6.6 V to 15 V span (required)
• RoHS3 Compliance: Required for regulatory alignment
• Moisture Sensitivity Level: 1 (Unlimited) preferred

Engineering Selection Recommendations

THS3201DBVR Selection Criteria: The THS3201DBVR is a direct electrical equivalent to the THS3201DBVRG4, maintaining identical performance specifications across all critical parameters: 9800 V/µs slew rate, 1.8 GHz bandwidth, and SOT-23-5 package compatibility. This part preserves circuit board layout and requires no design modifications. Current inventory availability is 5550 pieces. However, the THS3201DBVR carries a "Not For New Designs" product status designation, indicating Texas Instruments has limited long-term support for this component. This substitute is suitable for legacy system maintenance, repair operations, and short-term production runs where design continuity is prioritized over future product roadmap alignment.

THS3001IDGNR Selection Criteria: The THS3001IDGNR is a functional equivalent offering current feedback amplification with active product status from Texas Instruments. This part delivers superior performance in specific areas: lower input bias current (2 µA versus 14 µA), reduced supply current (6.6 mA versus 14 mA), and extended supply voltage range (9 V to 33 V versus 6.6 V to 15 V). However, the THS3001IDGNR exhibits reduced bandwidth performance (420 MHz versus 1.8 GHz) and lower slew rate (6500 V/µs versus 9800 V/µs). The package differs significantly: 8-HVSSOP versus SOT-23-5, requiring complete circuit board redesign. Current inventory is 2272 pieces. This substitute is appropriate for applications where bandwidth and slew rate requirements are less stringent than the original design, where extended supply voltage range provides system-level advantages, and where active product status ensures long-term availability and manufacturer support.

Compliance and Certification Alignment: All three parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and identical REACH and ECCN classifications, ensuring regulatory and supply chain compatibility across all substitution scenarios.

Frequently Asked Questions (FAQ)

Q1: Can THS3201DBVR be used as a direct replacement for THS3201DBVRG4 without circuit board modifications?

A: Yes. The THS3201DBVR is electrically and mechanically identical to the THS3201DBVRG4. Both parts use the SOT-23-5 package with identical pin assignments, and both deliver 9800 V/µs slew rate and 1.8 GHz bandwidth. No circuit board layout changes are required. The primary consideration is the "Not For New Designs" status, which indicates limited future manufacturer support.

Q2: What are the performance trade-offs when substituting THS3001IDGNR for THS3201DBVRG4?

A: The THS3001IDGNR provides lower input bias current (2 µA versus 14 µA) and reduced supply current consumption (6.6 mA versus 14 mA), beneficial for low-power applications. However, bandwidth is significantly reduced from 1.8 GHz to 420 MHz, and slew rate decreases from 9800 V/µs to 6500 V/µs. These reductions are acceptable only for applications with lower frequency requirements. The 8-HVSSOP package requires complete circuit board redesign.

Q3: Why does THS3001IDGNR have a wider supply voltage range than THS3201DBVRG4?

A: The THS3001IDGNR is designed for broader system-level applications and supports supply voltages from 9 V to 33 V, compared to the THS3201DBVRG4 range of 6.6 V to 15 V. This extended range provides flexibility in multi-supply systems but does not affect the core amplifier functionality for applications operating within the original 6.6 V to 15 V specification.

Q4: Is the THS3201DBVR suitable for new product designs?

A: No. The THS3201DBVR carries a "Not For New Designs" product status. Texas Instruments designates this status to indicate that the component is in mature or declining production phases. For new product development, the THS3001IDGNR (Active status) is the recommended choice, provided bandwidth and slew rate requirements are compatible with the lower specifications.

Q5: What packaging considerations apply when selecting between these substitutes?

A: The THS3201DBVRG4 and THS3201DBVR both use SOT-23-5 packaging (5-pin surface mount), enabling direct board-level substitution. The THS3001IDGNR uses 8-HVSSOP packaging (8-pin surface mount with exposed pad), requiring circuit board redesign, new PCB layout, and potential changes to supporting component placement and routing.

Q6: Are all three parts compliant with current environmental and regulatory standards?

A: Yes. All three parts are ROHS3 compliant, carry Moisture Sensitivity Level 1 (Unlimited), and share identical REACH and ECCN classifications (EAR99). They meet current environmental and export control requirements without distinction.

Q7: Which substitute should be selected for inventory replenishment of existing products?

A: For existing product support and maintenance, the THS3201DBVR is the appropriate choice due to electrical and mechanical equivalence. Current inventory of 5550 pieces supports sustained production. For long-term supply chain security and future product roadmap alignment, transition planning toward the THS3001IDGNR (Active status, 2272 pieces available) should be evaluated if application bandwidth and slew rate requirements permit.
