Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE2084ACDW are identified based on the following criteria:

Functional Equivalence Parameters:

• Amplifier Type: J-FET configuration
• Number of Circuits: 4 (quad amplifier)
• Package / Case: 16-SOIC form factor with 0.295" (7.50mm) width
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Electrical Performance Parameters:

• Slew Rate, Gain Bandwidth Product, Input Bias Current, Input Offset Voltage, Supply Current, Output Current, and Supply Voltage Range determine functional suitability within application constraints.

Compliance & Regulatory Parameters:

• Moisture Sensitivity Level (MSL), REACH Status, and ECCN classification must align with the original part.

The substitute parts listed below maintain the same package footprint and J-FET amplifier topology, enabling direct replacement in applications where the specified electrical parameters are compatible with circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

LT1058ISW#PBF Selection Criteria: This substitute is suitable for applications where the operating temperature range of -40°C ~ 85°C is required. The LT1058ISW#PBF maintains J-FET amplifier topology, quad configuration, and 16-SOIC package compatibility. All regulatory compliance parameters (RoHS3, MSL 1, REACH Unaffected, EAR99) align with the TLE2084ACDW. The electrical parameter differences (lower slew rate, lower gain bandwidth product, lower input bias current, lower supply current) must be evaluated against specific circuit requirements.

LT1058SW#PBF Selection Criteria: This substitute is suitable for applications with operating temperature range of 0°C ~ 70°C, matching the TLE2084ACDW temperature specification. The LT1058SW#PBF maintains identical J-FET amplifier topology, quad configuration, and 16-SOIC package footprint. All regulatory compliance parameters (RoHS3, MSL 1, REACH Unaffected, EAR99) are equivalent. The electrical parameter differences must be evaluated within circuit design constraints.

Compliance Verification: Both substitute parts maintain Active product status and full RoHS3 compliance. Moisture sensitivity level remains at MSL 1 (Unlimited) for both alternatives, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can LT1058ISW#PBF and LT1058SW#PBF be used interchangeably with TLE2084ACDW?

A: Both LT1058 variants share the same J-FET quad amplifier topology and 16-SOIC package footprint. The primary difference is operating temperature range: LT1058ISW#PBF operates -40°C ~ 85°C, while LT1058SW#PBF operates 0°C ~ 70°C (matching TLE2084ACDW). Selection depends on application temperature requirements and electrical parameter compatibility.

Q: What are the key electrical differences between TLE2084ACDW and LT1058 substitutes?

A: The TLE2084ACDW has higher slew rate (45 V/µs vs. 13 V/µs), higher gain bandwidth product (10 MHz vs. 5 MHz), higher input bias current (25 nA vs. 10 pA), and higher supply current (6.5 mA vs. 1.7 mA per 4 channels). The TLE2084ACDW also supports lower minimum supply voltage (4.5 V vs. 20 V). These differences must be evaluated against circuit design specifications.

Q: Are the package dimensions identical?

A: Yes. All three parts use 16-SOIC package with 0.295" (7.50mm) width, enabling direct PCB footprint compatibility.

Q: Do all parts have the same compliance certifications?

A: Yes. TLE2084ACDW, LT1058ISW#PBF, and LT1058SW#PBF are all RoHS3 compliant, MSL 1 (Unlimited), REACH Unaffected, and classified as EAR99. Regulatory requirements are equivalent across all three parts.

Q: Which substitute should be selected for low-temperature applications?

A: LT1058ISW#PBF supports operating temperature range of -40°C ~ 85°C, extending below the TLE2084ACDW specification of 0°C ~ 70°C. This part is suitable for applications requiring extended low-temperature operation.

Q: What is the impact of lower supply current in LT1058 substitutes?

A: LT1058 variants consume 1.7 mA (x4 channels) compared to TLE2084ACDW at 6.5 mA (x4 channels). This represents reduced power dissipation and lower thermal load, which may benefit power-constrained applications. Circuit design must verify that lower supply current does not impact required performance.

Q: Can TLE2084ACDW operate at supply voltages below 20 V?

A: Yes. TLE2084ACDW supports minimum supply voltage of 4.5 V, while LT1058 substitutes require minimum 20 V. For applications using supply voltages between 4.5 V and 20 V, only TLE2084ACDW is suitable.
