Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE2061CDRG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Amplifier Type: J-FET input architecture
• Package / Case: 8-SOIC form factor (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply Span: Minimum 7 V, Maximum 36 V
• Operating Temperature Range: Minimum 0°C, Maximum 70°C or broader

Secondary Compatibility Parameters:

• Number of Circuits: Single circuit preferred; dual-circuit devices acceptable with circuit-level design consideration
• Slew Rate: 3.4 V/µs or higher
• Gain Bandwidth Product: 2 MHz or higher
• Current - Input Bias: 4 pA or lower (lower values indicate superior performance)
• Voltage - Input Offset: 600 µV or lower
• Current - Output / Channel: 80 mA or higher

Substitute parts must maintain electrical compatibility within the 8-SOIC package envelope and support the specified supply voltage range. Parts with extended operating temperature ranges or enhanced performance characteristics are listed as active alternatives to the obsolete TLE2061CDRG4.

Parameter Comparison

Engineering Selection Recommendations

TLE2061CDR (Manufacturer Recommended Primary Substitute)

The TLE2061CDR is the direct equivalent to TLE2061CDRG4, manufactured by Texas Instruments. This part maintains identical electrical specifications, J-FET input architecture, single-circuit configuration, and 8-SOIC package form factor. The TLE2061CDR is currently in active production status with 12,600 units in stock, providing immediate design continuity. Packaging differs only in format (Tape & Reel versus Digi-Reel), with no impact on component functionality. This substitution requires no circuit redesign and is the preferred replacement for obsolete TLE2061CDRG4 applications.

AD8682ARZ (Performance-Enhanced Alternative)

The AD8682ARZ, manufactured by Analog Devices Inc., offers enhanced performance characteristics within the same 8-SOIC package. This dual-circuit J-FET amplifier provides superior slew rate (9 V/µs versus 3.4 V/µs), higher gain bandwidth product (3.5 MHz versus 2 MHz), and lower input offset voltage (350 µV versus 600 µV). The extended operating temperature range (-40°C to 85°C) supports broader environmental applications. However, the dual-circuit configuration and reduced output current per channel (12 mA versus 80 mA) require circuit-level evaluation. Minimum supply voltage requirement of 9 V exceeds the TLE2061CDRG4 specification of 7 V.

TL062ACDT (Cost-Optimized Alternative)

The TL062ACDT, manufactured by STMicroelectronics, is a dual-circuit J-FET amplifier in 8-SOIC package. This device supports the full 6 V to 36 V supply range and maintains J-FET input characteristics. The lower gain bandwidth product (1 MHz) and reduced output current per channel (20 mA) indicate reduced performance capability compared to the main part. Input bias current of 30 nA and input offset voltage of 3 mV represent degraded specifications. This substitution is suitable only for applications with relaxed performance requirements.

TS512IYDT (Extended Temperature / Automotive Grade)

The TS512IYDT, manufactured by STMicroelectronics, is a general-purpose dual-circuit amplifier with AEC-Q100 automotive qualification. This device supports extended operating temperature range (-40°C to 125°C) and operates from 3 V to 30 V supply. The general-purpose amplifier type differs from the J-FET input architecture of the main part. Reduced slew rate (1.5 V/µs) and higher supply current (500 µA for dual channels) indicate different performance characteristics. This substitution is applicable only for automotive-grade applications requiring extended temperature operation, with full circuit validation required.

Frequently Asked Questions (FAQ)

Q1: Can TLE2061CDR directly replace TLE2061CDRG4 without circuit modification?

A: Yes. The TLE2061CDR is electrically and functionally identical to TLE2061CDRG4. Both devices share identical specifications for slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. The only difference is packaging format (Tape & Reel versus Digi-Reel). No circuit redesign is required.

Q2: What are the key limitations when substituting AD8682ARZ for TLE2061CDRG4?

A: The AD8682ARZ introduces three design considerations: (1) Dual-circuit configuration requires single-circuit utilization or circuit redesign; (2) Minimum supply voltage of 9 V exceeds the 7 V minimum of TLE2061CDRG4, requiring supply voltage verification; (3) Output current per channel is reduced to 12 mA versus 80 mA, limiting load-driving capability. Enhanced performance characteristics (higher slew rate, bandwidth, and lower offset voltage) may benefit signal conditioning applications.

Q3: Is TL062ACDT suitable for high-output-current applications?

A: No. The TL062ACDT provides only 20 mA output current per channel, compared to 80 mA for TLE2061CDRG4. Applications requiring output currents exceeding 20 mA must retain TLE2061CDR or evaluate alternative high-current amplifier architectures.

Q4: Can TS512IYDT be used in non-automotive applications?

A: Yes, TS512IYDT is functionally available for non-automotive use. However, this device is a general-purpose amplifier, not a J-FET input amplifier. Applications dependent on J-FET input characteristics (ultra-low input bias current, high input impedance) should not substitute TS512IYDT. The extended temperature range (-40°C to 125°C) exceeds typical commercial requirements (0°C to 70°C).

Q5: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (TLE2061CDR, AD8682ARZ, TL062ACDT, TS512IYDT) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of TLE2061CDRG4.

Q6: What is the primary reason for TLE2061CDRG4 obsolescence?

A: The TLE2061CDRG4 is classified as obsolete by Texas Instruments. The active equivalent TLE2061CDR provides identical functionality with current production status and inventory availability. Design migration to TLE2061CDR is recommended for long-term supply chain stability.

Q7: Which substitute part requires the most extensive circuit validation?

A: The TS512IYDT requires the most comprehensive validation due to fundamental architecture differences (general-purpose versus J-FET input), altered electrical characteristics (lower slew rate, higher bias current), and different supply voltage range (3 V to 30 V). Full circuit simulation and prototype testing are mandatory before production implementation.
