THS3202DR Equivalent & Substitute Parts

Part Overview

The THS3202DR is a current feedback amplifier integrated circuit manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device contains two amplifier circuits and is classified as obsolete, indicating discontinued production and limited availability for new designs. The THS3202DR delivers high-speed amplification with a 9000V/µs slew rate and 2 GHz bandwidth, making it suitable for high-frequency signal conditioning applications. Due to its obsolete status, identifying functionally equivalent substitute components is necessary for design continuity, procurement alternatives, and long-term supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the THS3202DR are identified based on strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: Current Feedback architecture
• Number of Circuits: Dual-channel configuration (2 circuits)
• Package / Case: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting Type: Surface Mount technology
• RoHS Compliance: ROHS3 Compliant status
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Secondary Compatibility Parameters:

• Slew Rate: Minimum 800V/µs (substitute devices operate at reduced slew rate compared to THS3202DR)
• -3dB Bandwidth: Minimum 400 MHz (substitute devices operate at reduced bandwidth)
• Supply Voltage Range: Overlap within 4V to 12V operating window
• Operating Temperature: Functional within 0°C to 70°C range

The identified substitute parts LT1396CS8#PBF and LT1396CS8#TRPBF from Analog Devices Inc. satisfy all primary substitution criteria. Both variants are functionally identical, differing only in packaging format (Tube versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The THS3202DR is classified as obsolete, while both LT1396CS8#PBF and LT1396CS8#TRPBF are active products from Analog Devices Inc. Active product status ensures ongoing manufacturing, technical support, and supply chain availability for future procurement cycles.

Compliance and Certification: All three components maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with modern manufacturing processes and long-term storage requirements. Both substitute parts carry REACH Unaffected and EAR99 ECCN classifications, matching the regulatory profile of the original THS3202DR.

Packaging Format Selection: LT1396CS8#PBF is supplied in Tube packaging, suitable for lower-volume applications and manual assembly operations. LT1396CS8#TRPBF is supplied in Tape & Reel format, optimized for automated pick-and-place assembly with higher inventory availability (3800 pcs versus 1723 pcs). Selection between these variants depends on production volume and assembly methodology.

Performance Trade-offs: The LT1396 series operates at reduced slew rate (800V/µs versus 9000V/µs) and bandwidth (400 MHz versus 2 GHz) compared to the THS3202DR. Applications requiring the full performance envelope of the original device may not be suitable for direct substitution. Lower supply current consumption (4.6mA per channel versus 14mA) and reduced output current capability (80mA versus 120mA) must be evaluated against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can LT1396CS8#PBF and LT1396CS8#TRPBF be used interchangeably with THS3202DR?

A: Both LT1396 variants are functionally equivalent substitutes for the THS3202DR in applications where the reduced slew rate (800V/µs versus 9000V/µs) and bandwidth (400 MHz versus 2 GHz) are acceptable. The identical 8-SOIC package footprint and dual-channel current feedback architecture enable direct PCB layout compatibility. However, circuit performance characteristics will differ due to the lower speed specifications of the LT1396 series.

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

A: Both parts are electrically and functionally identical. The primary difference is packaging format: LT1396CS8#PBF is supplied in Tube packaging for manual handling and lower-volume applications, while LT1396CS8#TRPBF is supplied in Tape & Reel format for automated assembly processes. The Tape & Reel variant offers higher inventory availability and is optimized for high-volume production environments.

Q: Are there any temperature range limitations when substituting the THS3202DR?

A: Yes. The THS3202DR operates across -40°C to 85°C, while both LT1396 substitutes operate across 0°C to 70°C. Applications requiring operation below 0°C or above 70°C cannot use the LT1396 series as direct substitutes. Extended temperature range requirements necessitate alternative component selection.

Q: How do supply voltage requirements compare?

A: The THS3202DR requires 6.6V to 15V supply span, while LT1396 variants require 4V to 12V. The LT1396 series operates within a narrower voltage window. Designs operating at supply voltages above 12V or below 4V require verification of circuit compatibility before substitution.

Q: What are the implications of reduced output current capability?

A: The THS3202DR provides 120mA output current per channel, while LT1396 variants provide 80mA per channel. Applications requiring output currents exceeding 80mA per channel cannot use the LT1396 series. Load impedance and signal swing requirements must be evaluated to confirm compatibility.

Q: Do the substitute parts maintain the same RoHS and regulatory compliance?

A: Yes. Both LT1396CS8#PBF and LT1396CS8#TRPBF maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, REACH Unaffected status, and EAR99 ECCN classification, matching the regulatory profile of the THS3202DR.

Q: Which substitute part should be selected for new designs?

A: For new designs, either LT1396CS8#PBF or LT1396CS8#TRPBF is appropriate based on production volume and assembly methodology. The Tape & Reel variant (LT1396CS8#TRPBF) is recommended for high-volume automated assembly due to superior inventory availability and optimized handling for pick-and-place equipment.
