THS3202DRG4 Equivalent & Substitute Parts

Part Overview

The THS3202DRG4 is a Current Feedback Amplifier with 2 circuits in an 8-SOIC surface mount package, manufactured by Texas Instruments. This device is classified as Obsolete, making substitute parts necessary for new designs and production continuity. The THS3202DRG4 delivers high-speed amplification with a 2 GHz bandwidth and 9000V/µs slew rate, suitable for applications requiring wideband signal processing. Equivalent parts must maintain the same functional architecture (Current Feedback topology), circuit count (2 circuits), and physical package compatibility (8-SOIC form factor).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the THS3202DRG4 is based on strict alignment of the following critical parameters:

Mandatory Compatibility Criteria:

• Amplifier Type: Current Feedback topology
• Number of Circuits: 2 independent amplifier circuits
• Package / Case: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Performance Parameters for Functional Equivalence:

• Slew Rate: 9000V/µs (primary performance metric)
• -3dB Bandwidth: 2 GHz (primary performance metric)
• Current - Output / Channel: 120 mA (load-driving capability)
• Voltage - Supply Span: 6.6V to 15V (power supply compatibility)
• Operating Temperature: -40°C to 85°C (environmental operating range)

The substitute parts identified (LT1396CS8#PBF and LT1396CS8#TRPBF) share the same package, circuit count, and amplifier topology. However, they exhibit reduced performance specifications in slew rate and bandwidth compared to the THS3202DRG4, indicating they are functional substitutes for applications with lower bandwidth requirements rather than direct performance equivalents.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The THS3202DRG4 is classified as Obsolete. The substitute parts LT1396CS8#PBF and LT1396CS8#TRPBF are both Active products from Analog Devices Inc., ensuring long-term availability and continued manufacturing support.

Compliance & Certification: All three parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing processes and storage requirements. REACH status is Unaffected for all parts, and all carry EAR99 export classification.

Packaging & Inventory:

• LT1396CS8#PBF is supplied in Tube packaging with 1723 pcs in stock
• LT1396CS8#TRPBF is supplied in Tape & Reel (TR) packaging with 3800 pcs in stock

The Tape & Reel variant (LT1396CS8#TRPBF) is recommended for high-volume production due to superior inventory availability and automated assembly compatibility.

Performance Trade-offs: Substitution requires acceptance of reduced performance specifications. The LT1396 series operates at 800V/µs slew rate and 400 MHz bandwidth, compared to the THS3202DRG4's 9000V/µs and 2 GHz. This substitution is suitable only for applications with bandwidth requirements at or below 400 MHz. Applications requiring the full 2 GHz bandwidth and 9000V/µs slew rate of the THS3202DRG4 cannot use these substitutes.

Operating Temperature Range: The LT1396 series operates from 0°C to 70°C, which is narrower than the THS3202DRG4's -40°C to 85°C range. Applications requiring extended temperature operation below 0°C or above 70°C must verify alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the LT1396CS8#PBF and LT1396CS8#TRPBF be used interchangeably with the THS3202DRG4?

A: Both LT1396 variants are functionally compatible at the circuit topology and package level (8-SOIC, 2-circuit Current Feedback Amplifier). However, they are not performance equivalents. The LT1396 series delivers 800V/µs slew rate and 400 MHz bandwidth versus the THS3202DRG4's 9000V/µs and 2 GHz. Substitution is valid only for applications with bandwidth requirements at or below 400 MHz.

Q: What is the difference between LT1396CS8#PBF and LT1396CS8#TRPBF?

A: Both parts are electrically identical. The difference is packaging format: LT1396CS8#PBF is supplied in Tube packaging for manual assembly or small-volume applications, while LT1396CS8#TRPBF is supplied in Tape & Reel format for automated high-volume production. Tape & Reel packaging is standard for surface mount assembly lines.

Q: Are there any supply voltage compatibility issues when substituting?

A: The LT1396 series operates with a 4V to 12V supply span, while the THS3202DRG4 operates with 6.6V to 15V. If your design uses supply voltages between 12V and 15V, the LT1396 cannot be used. Verify your actual supply voltage range before substitution.

Q: What is the operating temperature impact of substitution?

A: The LT1396 series is rated for 0°C to 70°C operation, compared to the THS3202DRG4's -40°C to 85°C. If your application requires operation below 0°C or above 70°C, the LT1396 is not suitable. Confirm your actual operating temperature requirements before proceeding with substitution.

Q: How do the output current capabilities compare?

A: The THS3202DRG4 provides 120 mA per channel output current, while the LT1396 provides 80 mA per channel. If your circuit requires the full 120 mA output current capability, the LT1396 may not meet load-driving requirements. Verify your actual output current demands.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both LT1396CS8#PBF and LT1396CS8#TRPBF are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the THS3202DRG4's compliance profile.

Q: Which substitute part should I select for new production?

A: LT1396CS8#TRPBF (Tape & Reel) is recommended for production volumes due to higher inventory availability (3800 pcs) and compatibility with automated surface mount assembly equipment. LT1396CS8#PBF (Tube) is suitable for prototyping or low-volume applications.
