TLE2037CDR Equivalent & Substitute Parts

Part Overview

The TLE2037CDR is a general-purpose operational amplifier manufactured by Texas Instruments in the Excalibur™ series. This single-circuit, 8-SOIC surface-mount device operates across a wide supply voltage range of 8V to 38V and is designed for applications requiring moderate gain-bandwidth performance and low input offset voltage. The device is Active status and RoHS3 compliant, making it suitable for modern electronic applications.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining mechanical compatibility in the 8-SOIC package format. Substitution becomes necessary due to component availability, supply chain considerations, or design optimization requirements.

Engineering Selection Recommendations

Primary Substitutes (Closest Electrical Match):

The LT1360CS8#PBF and LT1360CS8#TRPBF (Analog Devices Inc.) provide the most direct electrical equivalence to the TLE2037CDR. Both devices maintain a 50 MHz gain-bandwidth product, matching the original specification exactly. The LT1360 series operates across a 5V to 30V supply range, which overlaps the TLE2037CDR's 8V to 38V range within the common operating window. These parts are classified as voltage-feedback amplifiers with C-Load™ series designation and are Active status with full RoHS3 compliance. The primary distinction is packaging: LT1360CS8#PBF is supplied in Tube format, while LT1360CS8#TRPBF is supplied in Tape & Reel (TR) format. Selection between these two depends on procurement and assembly requirements rather than electrical performance.

Secondary Substitutes (Enhanced Performance):

The LT1028CS8#PBF and LT1028CS8#TRPBF (Analog Devices Inc.) offer enhanced slew rate (15 V/µs versus 7.5 V/µs) and higher gain-bandwidth product (75 MHz versus 50 MHz). These devices are suitable for applications requiring faster transient response. Input bias current is doubled (30 nA versus 15 nA), and supply current is increased (7.6 mA versus 3.8 mA). Supply voltage range is 8V to 36V, which is compatible with the TLE2037CDR's minimum requirement but slightly reduced at the maximum. Both LT1028 variants are Active status with RoHS3 compliance.

Conditional Substitutes (Application-Dependent):

The LT1220CS8#PBF, LT1220CS8#TRPBF, LT1224CS8#PBF, and LT1224CS8#TRPBF are suitable only for applications where the TLE2037CDR's 7.5 V/µs slew rate is insufficient. The LT1220 series provides 250 V/µs slew rate with 45 MHz gain-bandwidth product and requires a minimum 10V supply (versus 8V for TLE2037CDR). The LT1224 series provides 400 V/µs slew rate with 45 MHz gain-bandwidth product and operates from 5V minimum. Both series have higher input bias current (100 nA and 4 µA respectively) and higher input offset voltage (500 µV versus 20 µV), making them suitable only for applications tolerant of these relaxed specifications.

Extended Temperature Range Option:

The OP37GS8#PBF (Analog Devices Inc.) operates across -25°C to 85°C, extending the temperature range beyond the TLE2037CDR's 0°C to 70°C specification. This device provides 17 V/µs slew rate and 63 MHz gain-bandwidth product. Input bias current matches the TLE2037CDR (15 nA), but input offset voltage is slightly higher (30 µV versus 20 µV). Supply voltage range is 8V to 36V. This part is suitable for applications requiring extended temperature operation.

All substitute parts maintain Active product status and full regulatory compliance (RoHS3, REACH Unaffected, MSL Level 1).

Frequently Asked Questions (FAQ)

Q: Can LT1360CS8#PBF be used as a direct replacement for TLE2037CDR without circuit modification?

A: Yes, within the overlapping supply voltage range (8V to 30V). Both devices share identical 50 MHz gain-bandwidth product, 8-SOIC package format, and compatible input/output specifications. The LT1360 operates at lower supply current (4 mA versus 3.8 mA) and has higher input bias current (300 nA versus 15 nA). Circuit verification is required if the application depends on input bias current specifications below 300 nA.

Q: What is the difference between LT1360CS8#PBF and LT1360CS8#TRPBF?

A: Both parts are electrically identical. The difference is packaging format: #PBF indicates Tube packaging for manual handling and small-quantity assembly, while #TRPBF indicates Tape & Reel (TR) packaging for automated pick-and-place assembly. Selection depends on manufacturing process requirements, not electrical performance.

Q: Can the LT1028CS8 series be used if the TLE2037CDR is unavailable?

A: Yes, for applications where increased slew rate (15 V/µs) and gain-bandwidth product (75 MHz) provide performance benefits. The LT1028 has doubled input bias current (30 nA) and increased supply current (7.6 mA). Supply voltage range is 8V to 36V, which is compatible with TLE2037CDR's minimum but slightly reduced at maximum. Verify that the application tolerates these parameter changes.

Q: Are the LT1220 and LT1224 series suitable substitutes for general-purpose applications?

A: The LT1220 and LT1224 series are conditional substitutes only for applications requiring slew rates significantly higher than 7.5 V/µs. Both series have substantially higher input offset voltage (500 µV versus 20 µV) and higher input bias current (100 nA to 4 µA). These relaxed specifications make them unsuitable for precision analog applications. Use only if the application explicitly requires high slew rate performance.

Q: What is the significance of the 8-SOIC package compatibility?

A: All substitute parts use the 8-SOIC (0.154", 3.90mm Width) package, ensuring mechanical and pin-compatible replacement on existing printed circuit boards. No PCB redesign or layout modification is required. Verify that the PCB footprint matches the 8-SOIC standard before substitution.

Q: Does the OP37GS8#PBF offer advantages over the TLE2037CDR?

A: The OP37GS8#PBF extends the operating temperature range to -25°C to 85°C (versus 0°C to 70°C for TLE2037CDR) and provides higher slew rate (17 V/µs versus 7.5 V/µs) and gain-bandwidth product (63 MHz versus 50 MHz). Input offset voltage is slightly higher (30 µV versus 20 µV). This part is suitable for applications requiring extended temperature operation or faster transient response.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed maintain RoHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory equivalence to the TLE2037CDR.

Q: What supply voltage range is common to all substitute parts and the TLE2037CDR?

A: The overlapping supply voltage range is 8V to 30V. The TLE2037CDR operates to 38V maximum, but most Analog Devices substitutes are rated to 30V maximum. Verify supply voltage requirements before substitution if operation above 30V is required.
