TLE2062ID Equivalent & Substitute Parts

Part Overview

The TLE2062ID is a J-FET input operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) device in an 8-SOIC surface mount package. This component is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory (1515 pcs). The TLE2062ID is designed for applications requiring low input bias current and low input offset voltage characteristics typical of J-FET amplifier architectures. Identification of equivalent and substitute parts is necessary due to the Last Time Buy status and potential future unavailability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2062ID is determined by the following critical parameters: amplifier type (J-FET), number of circuits (2), package type (8-SOIC), mounting method (surface mount), and electrical operating ranges (supply voltage span, temperature range). The substitute parts identified fall into two functional categories:

Category 1: Direct J-FET Equivalents Parts maintaining J-FET amplifier architecture with identical dual-channel configuration and 8-SOIC packaging. These parts preserve the low input bias current characteristic (4-20 pA range) essential for high-impedance signal sources.

Category 2: Functional Alternatives Parts with different amplifier types (Audio, General Purpose) but compatible package, pin count, and dual-channel configuration. These alternatives provide different electrical performance profiles suitable for applications where J-FET characteristics are not mandatory.

All substitute parts share the following compatibility criteria:

• 8-SOIC (0.154", 3.90mm Width) package
• Dual-channel (2 circuit) configuration
• Surface mount mounting type
• ROHS3 compliance
• MSL 1 rating

Engineering Selection Recommendations

TLE2062IDR (Texas Instruments) This part is the direct equivalent of TLE2062ID with identical electrical specifications and J-FET architecture. The primary distinction is product status: TLE2062IDR maintains Active status with significantly higher inventory availability (18739 pcs). This part is recommended as the primary substitute for applications currently using TLE2062ID, as it provides identical performance with assured long-term supply continuity. Packaging format differs (Cut Tape & Digi-Reel) but maintains the same 8-SOIC package specification.

TL072CDT (STMicroelectronics) This J-FET amplifier maintains the same amplifier type and dual-channel configuration as the main part. Key differences include higher slew rate (16 V/µs vs 3.4 V/µs), higher gain bandwidth product (4 MHz vs 2 MHz), and higher input bias current (20 pA vs 4 pA). Operating temperature range is narrower (0°C to 70°C vs -40°C to 85°C). This part is suitable for applications requiring faster signal response but with relaxed input bias current requirements. Automotive qualification (AEC-Q100) is provided. High inventory availability (203200 pcs) ensures supply security.

NCS20072DR2G (onsemi) This general-purpose amplifier offers rail-to-rail output capability not present in the main part. Input bias current (5 pA) is comparable to TLE2062ID. Key trade-offs include lower slew rate (2.4 V/µs), lower supply current (420 µA), and higher input offset voltage (1.3 mV). Operating temperature range extends to 125°C. Minimum supply voltage is lower (2.7 V). This part is applicable for low-power applications with extended temperature requirements and where rail-to-rail output is beneficial.

LM833DT (STMicroelectronics) This audio amplifier represents a functional alternative with significantly different electrical characteristics. Input bias current is substantially higher (300 nA vs 4 pA), making it unsuitable for high-impedance signal sources. Slew rate (7 V/µs) and gain bandwidth product (15 MHz) are substantially higher. Supply current is significantly elevated (4 mA). Operating temperature range extends to 105°C. This part is applicable only for audio-specific applications where the higher input bias current is acceptable. Highest inventory availability (166607 pcs) is available.

Frequently Asked Questions (FAQ)

Q: Can TLE2062IDR be used as a direct replacement for TLE2062ID? A: Yes. TLE2062IDR is electrically and functionally identical to TLE2062ID. Both parts share identical specifications for slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. The primary difference is product status (Active vs Last Time Buy) and packaging format (Cut Tape & Digi-Reel vs standard). Pin configuration and 8-SOIC package dimensions are identical.

Q: What is the key difference between J-FET amplifiers (TLE2062ID, TL072CDT) and the general-purpose amplifier (NCS20072DR2G)? A: J-FET amplifiers feature extremely low input bias current (4-20 pA range), making them suitable for high-impedance signal sources and precision measurement applications. The NCS20072DR2G general-purpose amplifier has comparable input bias current (5 pA) but adds rail-to-rail output capability. Selection depends on whether rail-to-rail output is required for the application.

Q: Why does LM833DT have such high input bias current compared to other options? A: LM833DT is classified as an audio amplifier with bipolar input stage architecture, resulting in input bias current of 300 nanoamperes. This is approximately 75,000 times higher than the J-FET amplifiers. Audio amplifiers prioritize different performance characteristics (higher slew rate, higher gain bandwidth product) over low input bias current. LM833DT is suitable only for applications where input bias current is not a limiting factor.

Q: What are the temperature range implications when selecting a substitute? A: TLE2062ID operates from -40°C to 85°C. TL072CDT has a narrower range (0°C to 70°C), making it unsuitable for applications requiring full -40°C to 85°C coverage. NCS20072DR2G and LM833DT extend to 125°C and 105°C respectively, providing broader high-temperature capability. Application temperature requirements must be verified before substitution.

Q: Are all substitute parts available in the same 8-SOIC package? A: Yes. All substitute parts (TLE2062IDR, TL072CDT, NCS20072DR2G, LM833DT) are packaged in 8-SOIC (0.154", 3.90mm Width) format. Pin count and package footprint are identical, enabling direct PCB layout compatibility. Supplier device package designations may vary (8-SOIC vs 8-SO) but refer to the same physical package specification.

Q: Which substitute part has the best long-term availability? A: TL072CDT has the highest inventory level (203200 pcs), followed by LM833DT (166607 pcs) and NCS20072DR2G (60300 pcs). TLE2062IDR has 18739 pcs available. For applications requiring assured supply continuity, TL072CDT or LM833DT are preferred if their electrical characteristics are compatible with application requirements.

Q: Can I use NCS20072DR2G in a circuit designed for TLE2062ID? A: Substitution is possible only if the application does not require the specific J-FET input characteristics of TLE2062ID. Key differences include lower slew rate (2.4 V/µs vs 3.4 V/µs), lower gain bandwidth product (3.2 MHz vs 2 MHz), higher input offset voltage (1.3 mV vs 900 µV), and lower minimum supply voltage (2.7 V vs 7 V). The rail-to-rail output capability of NCS20072DR2G may provide additional circuit design flexibility. Circuit simulation or bench testing is necessary to confirm compatibility.

Q: What does "Last Time Buy" status mean for TLE2062ID? A: Last Time Buy indicates that Texas Instruments has discontinued production of TLE2062ID and will not manufacture additional units beyond current inventory. The 1515 pcs currently in stock represent the final available supply. Once depleted, this part number will be permanently unavailable. Transition to an active substitute part is necessary for long-term product support and future production requirements.
