Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TLE2024ACN is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Amplifier Type (General Purpose vs. J-FET)
• Number of Circuits (4 independent channels required)
• Slew Rate (0.7 V/µs minimum)
• Gain Bandwidth Product (2.8 MHz minimum)
• Input Bias Current (45 nA maximum)
• Input Offset Voltage (750 µV maximum)
• Supply Current per channel (1.05 mA maximum)
• Output Current per channel (40 mA minimum)
• Supply Voltage Range (4V to 40V overlap required)
• Operating Temperature Range (0°C to 70°C minimum)

Mechanical Compatibility Criteria:

• Package Type (14-DIP through-hole for direct pin compatibility)
• Pin Count (14 pins)
• Physical Dimensions (0.300" width, 7.62mm)

Regulatory Compliance:

• RoHS3 Compliance
• REACH Status (Unaffected)

The substitute parts are grouped into two categories:

Category 1: Same Package, Same Manufacturer (TLE2024ACDWR) Surface-mount alternative from Texas Instruments with identical electrical specifications but different packaging (16-SOIC). Suitable for designs transitioning to surface-mount technology while maintaining the same silicon die and performance characteristics.

Category 2: Same Package, Different Manufacturer (LT1058ACN#PBF, OP11EPZ) Through-hole alternatives from Analog Devices Inc. with compatible package form factors. These devices maintain 14-DIP packaging but differ in amplifier type and electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

TLE2024ACDWR Selection Criteria: The TLE2024ACDWR is the manufacturer-recommended substitute from Texas Instruments. It provides identical electrical performance to the TLE2024ACN with matching slew rate (0.7 V/µs), gain bandwidth product (2.8 MHz), input bias current (45 nA), and input offset voltage (750 µV). The primary difference is packaging: 16-SOIC surface-mount versus 14-DIP through-hole. This substitute is appropriate for new designs or redesigns incorporating surface-mount assembly processes. Active product status ensures long-term availability. ROHS3 compliance and REACH unaffected status match the original part.

LT1058ACN#PBF Selection Criteria: The LT1058ACN#PBF maintains 14-DIP through-hole packaging for direct socket compatibility. However, this device is a J-FET amplifier with significantly different electrical characteristics: slew rate of 14 V/µs (20× higher), gain bandwidth product of 5 MHz (1.8× higher), and input bias current of 5 pA (9000× lower). These performance differences require circuit re-evaluation. The supply voltage range (20V to 36V) is narrower than the TLE2024ACN (4V to 40V), restricting application scope. Active product status and ROHS3 compliance are maintained.

OP11EPZ Selection Criteria: The OP11EPZ maintains 14-DIP through-hole packaging. As a general-purpose amplifier, it shares the same amplifier type classification as the TLE2024ACN. However, electrical parameters differ: slew rate of 1 V/µs (versus 0.7 V/µs), input bias current of 180 nA (versus 45 nA), and input offset voltage of 300 µV (versus 750 µV). The supply voltage range (10V to 30V) is narrower than the TLE2024ACN. Gain bandwidth product is not specified. Active product status and ROHS3 compliance are maintained.

Recommendation Summary: For designs requiring identical electrical performance with packaging flexibility, select TLE2024ACDWR. For through-hole designs requiring direct socket replacement with minimal circuit modification, evaluate LT1058ACN#PBF or OP11EPZ only after confirming that their different electrical characteristics are compatible with the application circuit.

Frequently Asked Questions (FAQ)

Q1: Can TLE2024ACDWR be used as a direct replacement for TLE2024ACN?

A: TLE2024ACDWR provides identical electrical performance but differs in packaging. The TLE2024ACN uses 14-DIP through-hole mounting, while TLE2024ACDWR uses 16-SOIC surface-mount. Direct socket replacement is not possible without PCB redesign. However, the electrical specifications are fully compatible, making it suitable for new designs or PCB revisions.

Q2: What are the key differences between TLE2024ACN and LT1058ACN#PBF?

A: Both devices use 14-DIP packaging and operate across 0°C to 70°C. However, LT1058ACN#PBF is a J-FET amplifier with superior performance: slew rate of 14 V/µs versus 0.7 V/µs, gain bandwidth product of 5 MHz versus 2.8 MHz, and input bias current of 5 pA versus 45 nA. The supply voltage range differs: LT1058ACN#PBF requires 20V to 36V, while TLE2024ACN operates from 4V to 40V. Circuit re-evaluation is required before substitution.

Q3: Is OP11EPZ a suitable replacement for TLE2024ACN?

A: OP11EPZ maintains 14-DIP through-hole packaging and general-purpose amplifier classification. However, electrical parameters differ: slew rate of 1 V/µs versus 0.7 V/µs, input bias current of 180 nA versus 45 nA, and input offset voltage of 300 µV versus 750 µV. The supply voltage range (10V to 30V) is narrower than TLE2024ACN (4V to 40V). Substitution requires circuit analysis to confirm compatibility with the application's performance requirements and supply voltage specifications.

Q4: Why does TLE2024ACN have Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLE2024ACN. Existing inventory is available for purchase, but no future production is planned. This status necessitates identification of equivalent parts for long-term product support and design continuity.

Q5: Are all substitute parts RoHS3 compliant?

A: Yes. TLE2024ACDWR, LT1058ACN#PBF, and OP11EPZ are all ROHS3 compliant and REACH unaffected, matching the regulatory compliance status of the original TLE2024ACN.

Q6: What is the primary advantage of TLE2024ACDWR over through-hole alternatives?

A: TLE2024ACDWR provides identical electrical performance to TLE2024ACN while offering surface-mount packaging (16-SOIC). This enables integration into modern PCB assembly processes and reduces board space requirements. Active product status ensures long-term availability compared to the Last Time Buy status of the original part.

Q7: Can LT1058ACN#PBF be used in low-voltage applications below 20V?

A: No. LT1058ACN#PBF requires a minimum supply voltage of 20V, making it unsuitable for applications operating below this threshold. TLE2024ACN operates from 4V minimum, providing broader low-voltage application support. OP11EPZ operates from 10V minimum, also limiting low-voltage compatibility.

Q8: Which substitute part has the lowest input bias current?

A: LT1058ACN#PBF has the lowest input bias current at 5 pA, compared to 45 nA for TLE2024ACN and 180 nA for OP11EPZ. This J-FET input stage characteristic makes LT1058ACN#PBF suitable for high-impedance input applications where input bias current must be minimized.
