TLE2064IDRG4 Equivalent & Substitute Parts

Part Overview

The TLE2064IDRG4 is a J-FET input operational amplifier featuring four independent circuits in a 14-SOIC surface mount package, manufactured by Texas Instruments. This device is designed for applications requiring low input bias current and low input offset voltage characteristics inherent to J-FET amplifier topology.

The TLE2064IDRG4 is currently discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components that maintain functional compatibility while meeting application requirements. Substitute parts must preserve the four-circuit configuration, J-FET amplifier type, 14-SOIC package format, and critical electrical parameters within acceptable tolerances.

Substitute Part Grouping Explanation

Substitution compatibility for the TLE2064IDRG4 is determined by the following mandatory criteria:

Primary Compatibility Requirements:

Four independent operational amplifier circuits
J-FET input amplifier topology
14-SOIC surface mount package (0.154", 3.90mm width)
Supply voltage range compatibility (minimum 7V to maximum 36V)
Operating temperature range coverage

Secondary Compatibility Considerations:

Slew rate performance (3.4 V/µs baseline)
Gain bandwidth product (2 MHz baseline)
Input bias current (4 pA baseline)
Input offset voltage (900 µV baseline)
Output current per channel (80 mA baseline)

Substitute parts are grouped into two categories based on amplifier topology:

Category 1: Direct J-FET Substitutes — Parts maintaining J-FET input architecture with comparable or enhanced electrical performance characteristics. These include TLE2064IDR, LF247DT, LF347D, LF347DT, TL074IYDT, TL084ACDT, TL084AIDT, and TL084BIDT.

Category 2: General Purpose Substitutes — Parts with general purpose amplifier topology (LM2902DR2G, SC2902DR2G) that share the four-circuit configuration and 14-SOIC package but differ in input bias current and supply voltage specifications.

Engineering Selection Recommendations

Primary Substitute: TLE2064IDR

The TLE2064IDR is the direct equivalent to TLE2064IDRG4, manufactured by Texas Instruments with identical electrical specifications and 14-SOIC packaging. This part maintains all critical parameters including 3.4 V/µs slew rate, 2 MHz gain bandwidth product, 4 pA input bias current, and 900 µV input offset voltage. The TLE2064IDR is currently in active production status with 2050 pieces in stock, providing immediate availability. This part is ROHS3 compliant and carries MSL 1 rating identical to the original part.

Secondary J-FET Substitutes: TL084AIDT, TL084BIDT

The TL084AIDT and TL084BIDT from STMicroelectronics provide enhanced performance characteristics while maintaining J-FET input topology and 14-SOIC packaging. Both parts feature 16 V/µs slew rate and 4 MHz gain bandwidth product, exceeding the original specification. The TL084AIDT operates across -40°C to 105°C temperature range, extending the upper limit by 20°C. The TL084BIDT offers improved input offset voltage specification of 1 mV compared to the original 3 mV. Both parts carry AEC-Q100 automotive qualification and are ROHS3 compliant.

Alternative J-FET Substitutes: TL074IYDT, LF247DT, LF347DT

The TL074IYDT provides supply voltage range compatibility (6V to 36V) matching the original part's lower supply limit while offering extended temperature range (-40°C to 105°C). The LF247DT and LF347DT from STMicroelectronics feature enhanced slew rate (16 V/µs) and gain bandwidth product (4 MHz) but operate at fixed 44V supply voltage, limiting applicability to designs requiring variable supply voltages.

General Purpose Alternatives: LM2902DR2G, SC2902DR2G

The LM2902DR2G and SC2902DR2G are general purpose operational amplifiers with four circuits in 14-SOIC packaging. These parts are not recommended as direct substitutes due to significantly higher input bias current (90 nA versus 4 pA) and different amplifier topology. These parts are suitable only for applications where J-FET input characteristics are not critical and lower supply voltage operation (3V minimum) is required.
