TLE2064ID Equivalent & Substitute Parts

Part Overview

The TLE2064ID is a J-FET input operational amplifier containing four independent circuits in a 14-SOIC surface mount package, manufactured by Texas Instruments. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The TLE2064ID operates across a wide supply voltage range of 7V to 36V and maintains low input bias current of 4 pA, making it suitable for precision analog signal processing applications requiring high input impedance.

Finding equivalent and substitute parts is necessary due to the Last Time Buy status of the TLE2064ID. Alternative models provide continued design support, extended product lifecycles, and maintained inventory levels for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution of the TLE2064ID is determined by strict alignment of electrical and mechanical parameters within the J-FET operational amplifier category. The critical substitution criteria are:

Primary Substitution Parameters:

Amplifier Type: J-FET input architecture
Number of Circuits: 4 independent amplifier stages
Package / Case: 14-SOIC form factor with 0.154" (3.90mm) width
Mounting Type: Surface Mount
Supply Voltage Range: Minimum 7V to maximum 36V compatibility
Input Bias Current: 4 pA specification
Output Current per Channel: 80 mA capability

Direct Substitutes (Identical Electrical Performance): The TLE2064IDR represents the manufacturer-recommended direct substitute, maintaining identical electrical specifications while offering improved product status (Active vs. Last Time Buy) and alternative packaging options (Cut Tape & Digi-Reel vs. Tube).

Functional Equivalents (Compatible Within Application Constraints): Parts including LF347M/NOPB, LF347MX/NOPB, LF444CM/NOPB, LF444CMX/NOPB, LF247DT, LF347D, and LF347DT provide J-FET input amplifier functionality in 14-SOIC packaging. These devices maintain the four-circuit configuration and surface mount compatibility but exhibit variations in slew rate, gain bandwidth product, input bias current, supply current, and operating temperature ranges. Selection among these alternatives requires verification that the application tolerates the specified parameter deviations.

Cross-Manufacturer Alternatives: The LM224DR2G and LM2902EDR2G represent general-purpose amplifier alternatives from onsemi. These devices differ fundamentally in amplifier type (General Purpose vs. J-FET), input bias current characteristics (90 nA vs. 4 pA), and supply voltage minimums (3V vs. 7V). These parts are suitable only for applications where J-FET input characteristics are not required.

Engineering Selection Recommendations

Tier 1 - Direct Replacement: The TLE2064IDR is the manufacturer-recommended substitute for the TLE2064ID. This part maintains identical electrical specifications and 14-SOIC packaging. The transition from Last Time Buy to Active product status ensures continued availability and manufacturing support. Both parts carry ROHS3 compliance and MSL Level 1 rating. Selection of TLE2064IDR is appropriate for all applications currently using TLE2064ID without circuit modification.

Tier 2 - J-FET Functional Equivalents: The LF347M/NOPB, LF347MX/NOPB, LF247DT, LF347D, and LF347DT maintain J-FET input architecture and 14-SOIC packaging. These devices are suitable for applications where the TLE2064ID's specific performance envelope (3.4V/µs slew rate, 2 MHz gain bandwidth product, 4 pA input bias current) can be relaxed. The LF347 series offers higher slew rates (13-16 V/µs) and gain bandwidth products (3-4 MHz), while the LF444 series provides lower power consumption (0.6 mA supply current) at the cost of reduced slew rate (1 V/µs) and gain bandwidth product (1 MHz). All Tier 2 alternatives maintain Active product status and ROHS3 compliance.

Tier 3 - General Purpose Alternatives: The LM224DR2G and LM2902EDR2G represent general-purpose amplifier architectures with significantly different input bias current characteristics (90 nanoamperes vs. 4 picoamperes). These parts are suitable only for applications where high input impedance and ultra-low input bias current are not design requirements. The LM224DR2G operates from 3V minimum supply voltage, extending applicability to lower-voltage systems. Both parts maintain Active status and ROHS3 compliance.

Compliance and Certification: All substitute parts listed carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, matching the TLE2064ID certification profile. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001, maintaining consistent export and tariff classification.

Frequently Asked Questions (FAQ)

Q: Can TLE2064IDR be used as a direct drop-in replacement for TLE2064ID?

A: Yes. The TLE2064IDR maintains identical electrical specifications, 14-SOIC packaging, and surface mount compatibility. The only difference is product status (Active vs. Last Time Buy) and packaging format (Cut Tape & Digi-Reel vs. Tube). No circuit modifications are required.

Q: What is the primary difference between TLE2064ID and LF347 series devices?

A: The TLE2064ID operates with a 2 MHz gain bandwidth product and 3.4 V/µs slew rate. The LF347 series (LF347M/NOPB, LF347MX/NOPB, LF347D, LF347DT) provides 3-4 MHz gain bandwidth product and 13-16 V/µs slew rate, enabling faster signal processing. The LF347 series also requires a minimum 10V supply voltage compared to 7V for the TLE2064ID.

Q: Are LF444 series devices suitable replacements for TLE2064ID?

A: LF444 series devices (LF444CM/NOPB, LF444CMX/NOPB) maintain J-FET input architecture and 14-SOIC packaging but operate at reduced performance levels: 1 V/µs slew rate, 1 MHz gain bandwidth product, and 0.6 mA supply current. These devices are appropriate only for applications where lower power consumption is prioritized over signal processing speed. The LF444 series requires a fixed 36V supply voltage.

Q: What is the significance of input bias current differences among substitute parts?

A: Input bias current determines the impedance loading on the signal source. The TLE2064ID specifies 4 pA input bias current, characteristic of J-FET input amplifiers. The LF347 series specifies 20 pA, and the LF444 series specifies 10 pA. General-purpose alternatives (LM224DR2G, LM2902EDR2G) specify 90 nanoamperes, representing a 22,500-fold increase. Applications requiring high input impedance or low source loading must maintain J-FET input architecture.

Q: Can LM224DR2G or LM2902EDR2G replace TLE2064ID?

A: These general-purpose amplifiers differ fundamentally in input bias current (90 nanoamperes vs. 4 picoamperes) and amplifier architecture (bipolar vs. J-FET). Substitution is appropriate only for applications where J-FET input characteristics are not required and where the 22,500-fold increase in input bias current does not degrade circuit performance.

Q: What packaging options are available for TLE2064 equivalent devices?

A: The TLE2064ID is supplied in Tube packaging. The TLE2064IDR is available in Cut Tape (CT) & Digi-Reel format. All substitute parts maintain 14-SOIC (0.154", 3.90mm width) surface mount packaging. Packaging format selection depends on production volume and assembly equipment compatibility; electrical performance is independent of packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification and MSL Level 1 (Unlimited) moisture sensitivity ratings, matching the TLE2064ID compliance profile.

Q: What is the operating temperature range consideration for substitute selection?

A: The TLE2064ID operates from -40°C to 85°C. The LF347 series operates from 0°C to 70°C (commercial grade). The LF247DT and LM2902EDR2G extend to -40°C to 105°C (industrial grade). Application temperature requirements must be verified against the selected substitute part's operating range.
