TLE2037IDR Equivalent & Substitute Parts

Part Overview

The TLE2037IDR is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as a linear amplifier with a single circuit configuration and is currently in active product status. The TLE2037IDR is part of the Excalibur™ series and is designed for applications requiring moderate bandwidth and low input offset voltage characteristics.

Identification of equivalent and substitute parts becomes necessary when the primary component is unavailable, when alternative packaging formats are required, or when design specifications permit the use of components with enhanced electrical performance within the same functional category.

Substitute Part Grouping Explanation

Substitution of the TLE2037IDR with the LT1028CS8#PBF is permissible based on the following criteria:

Functional Compatibility: Both devices are general-purpose operational amplifiers with a single circuit configuration housed in 8-SOIC surface mount packages with identical physical dimensions (0.154", 3.90mm Width). Both operate across the same temperature range (0°C to 70°C) and support identical supply voltage specifications (minimum 8V, maximum 36V for LT1028CS8#PBF and 38V for TLE2037IDR).

Electrical Parameter Alignment: The LT1028CS8#PBF maintains the same input offset voltage specification (20 µV) as the TLE2037IDR. Both devices deliver 50 mA output current per channel and operate with unlimited moisture sensitivity (MSL 1). The substitute part exhibits enhanced performance in slew rate (15 V/µs versus 7.5 V/µs) and gain bandwidth product (75 MHz versus 50 MHz), making it suitable for applications where the original specification is met or exceeded.

Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory equivalence.

Key Substitution Parameters: Amplifier type, number of circuits, package dimensions, mounting type, operating temperature range, supply voltage compatibility, input offset voltage, output current capability, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The TLE2037IDR remains the preferred component when original specifications are required and inventory is available. This device is in active product status with 1315 units in stock and carries full ROHS3 compliance and REACH unaffected certification.

Substitute Part Selection: The LT1028CS8#PBF is an acceptable substitute when the TLE2037IDR is unavailable or when enhanced performance characteristics are beneficial to the application. The substitute part is also in active product status with 5923 units available and maintains identical regulatory compliance. The LT1028CS8#PBF provides superior slew rate and gain bandwidth product performance while maintaining electrical compatibility in critical parameters including input offset voltage and output current capability.

Packaging Consideration: The TLE2037IDR is supplied in Tape & Reel (TR) packaging, while the LT1028CS8#PBF is supplied in Tube packaging. Both devices use identical 8-SOIC surface mount packages with matching physical dimensions, ensuring PCB-level compatibility.

Supply Voltage Consideration: The LT1028CS8#PBF operates with a maximum supply voltage of 36V, compared to 38V for the TLE2037IDR. Applications requiring operation above 36V must use the TLE2037IDR.

Current Consumption Consideration: The LT1028CS8#PBF draws 7.6 mA supply current, double that of the TLE2037IDR at 3.8 mA. Power budget constraints may influence component selection.

Frequently Asked Questions (FAQ)

Q: Can the LT1028CS8#PBF be used as a direct replacement for the TLE2037IDR in all applications?
