Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL35072P is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of circuits: 2 independent amplifier circuits required
• Package type: 8-DIP through-hole configuration (0.300", 7.62mm)
• Supply voltage range: Minimum 4V to maximum 44V compatibility
• Operating temperature range: Support for -55°C to 125°C or compatible subset
• Amplifier type classification: General Purpose, J-FET, or Audio amplifier types

Secondary Compatibility Parameters:

• Slew rate: 13V/µs baseline; higher values acceptable
• Gain bandwidth product: 4.5 MHz baseline; higher values acceptable
• Input bias current: 1 pA baseline; lower values preferred
• Input offset voltage: 300 µV baseline; lower values preferred
• Output current per channel: 30 mA baseline; higher values acceptable

Substitute parts are grouped into three categories based on amplifier type and electrical characteristics: General Purpose amplifiers with standard performance, J-FET amplifiers with low input bias current, and Audio amplifiers with optimized frequency response. All substitute parts maintain the 8-DIP through-hole package format and support the required supply voltage range.

Engineering Selection Recommendations

Direct Package-Compatible Substitutes (8-DIP Through-Hole):

The following parts maintain identical 8-DIP through-hole packaging and are suitable for direct board-level substitution without PCB modification:

• AD708JNZ (Analog Devices Inc.): Active product status. ROHS3 compliant. Operates within 0°C to 70°C temperature range, which is a subset of the TL35072P range. Suitable for applications not requiring extended low-temperature operation below 0°C.

• AS358P-E1 (Diodes Incorporated): Active product status. ROHS3 compliant. Operates within -40°C to 85°C temperature range. Minimum supply voltage of 3V provides enhanced low-voltage capability. Highest inventory availability (67,400 pcs). Suitable for cost-sensitive applications with standard temperature requirements.

• LT1057CN8#PBF (Analog Devices Inc.): Active product status. ROHS3 compliant. J-FET input type with 7 pA input bias current and 200 µV input offset voltage. Operates within 0°C to 70°C. Minimum supply voltage requirement of 20V restricts use to higher-voltage applications.

• LT1113CN8#PBF (Analog Devices Inc.): Active product status. ROHS3 compliant. J-FET input type with 300 pA input bias current. Operates within -40°C to 85°C. Minimum supply voltage of 9V. Suitable for applications requiring low input bias current with moderate temperature range.

• LT1169CN8#PBF (Analog Devices Inc.): Active product status. ROHS3 compliant. J-FET input type with 4 pA input bias current (lowest among J-FET options). Operates within 0°C to 70°C. Minimum supply voltage of 9V. Optimal for precision applications requiring minimal input bias current.

• MUSES01 (Nisshinbo Micro Devices Inc.): Active product status. RoHS compliant. Audio amplifier classification with optimized frequency response. Operates within -40°C to 85°C. Minimum supply voltage of 18V. Suitable for audio signal processing applications.

• OP275GPZ (Analog Devices Inc.): Active product status. ROHS3 compliant. Audio amplifier classification with 22V/µs slew rate and 9 MHz gain bandwidth product. Operates within -40°C to 85°C. Maximum supply voltage of 44V matches TL35072P. Suitable for high-performance audio applications.

Surface-Mount Alternative (Package Conversion Required):

• TLV9362IDR (Texas Instruments): Active product status. Rail-to-rail output configuration. 8-SOIC surface-mount package requires PCB redesign and assembly process modification. Enhanced performance specifications: 25V/µs slew rate, 10.6 MHz gain bandwidth product, 60 mA output current per channel. Operates within -40°C to 125°C, matching extended temperature range of TL35072P. Suitable only when PCB redesign is feasible and surface-mount assembly capability is available.

Selection Criteria Summary:

For direct through-hole substitution without PCB modification, prioritize parts with active product status and ROHS3 compliance. Verify minimum supply voltage compatibility with application requirements. For applications requiring extended low-temperature operation below 0°C, only OP275GPZ and TLV9362IDR support the full -55°C to 125°C range; however, TLV9362IDR requires package conversion. For cost-optimized designs with standard temperature requirements, AS358P-E1 offers highest inventory availability and lowest supply voltage minimum (3V).

Frequently Asked Questions (FAQ)

Q1: Can TLV9362IDR directly replace TL35072P on existing PCBs?

A: No. TLV9362IDR uses 8-SOIC surface-mount packaging, while TL35072P uses 8-DIP through-hole packaging. Direct board-level substitution is not possible without PCB redesign and assembly process modification. All other listed substitutes maintain 8-DIP through-hole compatibility for direct substitution.

Q2: Which substitute part best matches the TL35072P operating temperature range of -55°C to 125°C?

A: Only TLV9362IDR (-40°C to 125°C) and OP275GPZ (-40°C to 85°C) support temperatures above 85°C. TLV9362IDR provides the closest match to the upper temperature limit. However, TLV9362IDR requires surface-mount conversion. For through-hole applications requiring extended high-temperature operation, OP275GPZ is the only viable option, though it does not support the full -55°C lower limit.

Q3: What is the primary difference between General Purpose, J-FET, and Audio amplifier types in this list?

A: General Purpose amplifiers (AD708JNZ, AS358P-E1) provide standard performance across general applications. J-FET amplifiers (LT1057CN8#PBF, LT1113CN8#PBF, LT1169CN8#PBF) feature extremely low input bias current (4 to 300 pA), suitable for high-impedance signal sources and precision measurement circuits. Audio amplifiers (MUSES01, OP275GPZ) are optimized for audio frequency response and typically feature higher slew rates and output current capability.

Q4: Which substitute offers the lowest input bias current?

A: LT1169CN8#PBF provides the lowest input bias current at 4 pA among J-FET options. AD708JNZ offers 1 nA (1000 pA), which is higher but still acceptable for many applications. Selection depends on application sensitivity to input bias current effects.

Q5: Can AS358P-E1 operate at the TL35072P minimum supply voltage of 4V?

A: No. AS358P-E1 has a minimum supply voltage of 3V, which is lower than 4V. However, this does not prevent substitution in applications using 4V or higher supply voltages. AS358P-E1 is compatible with all supply voltages from 3V to 36V, which encompasses the 4V to 44V range of TL35072P, except for the 40V to 44V upper range.

Q6: What is the inventory status of substitute parts?

A: All substitute parts listed are in active production with new original stock available: TLV9362IDR (2,702 pcs), AD708JNZ (3,352 pcs), AS358P-E1 (67,400 pcs), LT1057CN8#PBF (1,522 pcs), LT1113CN8#PBF (1,123 pcs), LT1169CN8#PBF (938 pcs), MUSES01 (3,713 pcs), OP275GPZ (2,990 pcs). AS358P-E1 offers the highest inventory availability.

Q7: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are either ROHS3 compliant or RoHS compliant. TLV9362IDR is listed as "Not applicable" for RoHS status, which does not indicate non-compliance but rather a different regulatory classification. All parts meet environmental compliance requirements for modern electronics manufacturing.

Q8: Which substitute part has the highest output current capability?

A: OP275GPZ provides 90 mA output current per channel, compared to TL35072P's 30 mA. TLV9362IDR offers 60 mA per channel. These higher output current ratings enable driving lower-impedance loads or multiple stages without additional buffering.

Q9: For applications requiring supply voltages above 40V, which substitutes are suitable?

A: Only TL35072P (44V max) and OP275GPZ (44V max) support the full 44V supply voltage. All other substitutes have maximum supply voltages of 36V to 40V. For applications requiring 40V to 44V operation, OP275GPZ is the only viable through-hole substitute.

Q10: What is the impact of using a substitute with different slew rate specifications?

A: Slew rate determines the maximum rate of voltage change at the output. TL35072P has 13V/µs slew rate. Substitutes with higher slew rates (TLV9362IDR at 25V/µs, OP275GPZ at 22V/µs) provide improved transient response and are backward compatible. Substitutes with lower slew rates (AD708JNZ at 0.3V/µs, LT1113CN8#PBF at 3.9V/µs) may limit high-frequency performance and require circuit verification for time-dependent applications.
