TSV358IPT Equivalent & Substitute Parts
Part Overview
The TSV358IPT is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a dual-circuit (2-channel) rail-to-rail amplifier in an 8-TSSOP surface-mount package. This device is classified as Active product status and carries automotive-grade qualification (AEC-Q100), making it suitable for demanding automotive and industrial applications. The TSV358IPT operates across a supply voltage range of 2.5 V to 6 V with an operating temperature range of -40°C to 125°C.
Equivalent and substitute parts are identified when alternative manufacturers offer operational amplifiers with compatible electrical characteristics, identical or superior performance parameters, matching package configurations, and equivalent compliance certifications. Substitution becomes necessary due to supply chain constraints, inventory availability, design optimization requirements, or manufacturer discontinuation.

Engineering Selection Recommendations
Direct Package Equivalents (8-TSSOP):
The NCS20082DTBR2G and NCV20082DTBR2G from onsemi are direct package equivalents to the TSV358IPT, both utilizing the 8-TSSOP surface-mount package. Both devices support the full operating temperature range of -40°C to 125°C and maintain RoHS3 compliance with MSL 1 rating. These parts demonstrate lower supply current consumption (48 µA versus 500 µA) and reduced input bias current (1 pA versus 70 nA), representing improved power efficiency. However, output current per channel is reduced to 15 mA compared to the TSV358IPT's 80 mA capability. These substitutes are suitable for applications where output current requirements do not exceed 15 mA per channel.
Functional Equivalents with Alternative Packages:
The OPA2313IDGKR from Texas Instruments utilizes an 8-VSSOP package and supports the full -40°C to 125°C operating temperature range with RoHS3 compliance. This device exhibits superior input bias current performance (0.2 pA) and maintains MSL 2 rating. Output current per channel is limited to 15 mA. The OPA2313IDGKR is suitable for applications requiring minimal input bias current and where package footprint optimization is acceptable.
The MCP6L02T-E/MS from Microchip Technology employs an 8-MSOP package and supports the full -40°C to 125°C operating temperature range with RoHS3 compliance and MSL 1 rating. This device matches the TSV358IPT's slew rate (0.6 V/µs) and supply voltage maximum (6 V), with output current per channel of 20 mA. The MCP6L02T-E/MS is suitable for applications requiring extended temperature operation and improved power efficiency.
CMOS Alternative:
The AZV832MMTR-G1 from Diodes Incorporated is a CMOS amplifier in 8-MSOP package with exceptional input bias current (1 pA) and lowest supply current consumption (70 µA). However, this device operates only to 85°C maximum temperature and carries MSL 3 rating, making it unsuitable for automotive-grade applications requiring AEC-Q100 qualification or extended temperature operation to 125°C.
Automotive and Compliance Considerations:
The TSV358IPT carries automotive-grade qualification (AEC-Q100) and operates to 125°C. Among the listed substitutes, only the NCS20082DTBR2G, NCV20082DTBR2G, OPA2313IDGKR, and MCP6L02T-E/MS support the full -40°C to 125°C temperature range. The AZV832MMTR-G1 is limited to -40°C to 85°C and is not suitable for automotive applications requiring extended temperature operation.
Frequently Asked Questions (FAQ)
Q: Can the NCS20082DTBR2G or NCV20082DTBR2G directly replace the TSV358IPT in all applications?
A: These onsemi devices are direct package equivalents in 8-TSSOP format and support identical operating temperature ranges (-40°C to 125°C). However, output current per channel is reduced from 80 mA to 15 mA. Direct substitution is valid only for applications where output current requirements do not exceed 15 mA per channel. Verify output current specifications in your circuit design before substitution.
Q: What is the difference between 8-TSSOP, 8-MSOP, and 8-VSSOP packages?
A: All three are 8-pin surface-mount packages with different physical dimensions. The 8-TSSOP (0.173", 4.40mm width) is the original package for the TSV358IPT. The 8-MSOP (0.118", 3.00mm width) and 8-VSSOP (0.118", 3.00mm width) are smaller footprints. Pin configurations are identical across these packages, allowing functional substitution with PCB layout modifications to accommodate different package dimensions.
Q: Why does the TSV358IPT have higher supply current (500 µA) compared to substitute parts?
A: The TSV358IPT's higher supply current reflects its design for higher output current capability (80 mA per channel). Substitute parts with lower supply current (48-85 µA) typically provide reduced output current (15-20 mA per channel). This represents a design trade-off between power consumption and output drive capability. Select substitutes based on your application's output current requirements.
Q: Is the OPA2313IDGKR suitable for automotive applications?
A: The OPA2313IDGKR supports the full -40°C to 125°C operating temperature range and maintains RoHS3 compliance. However, it does not carry explicit automotive-grade qualification (AEC-Q100) in the provided specifications. For applications requiring AEC-Q100 certification, the NCS20082DTBR2G, NCV20082DTBR2G, or MCP6L02T-E/MS are preferred substitutes.
Q: What does MSL (Moisture Sensitivity Level) mean for component selection?
A: MSL indicates the maximum time a component can be exposed to moisture before soldering. MSL 1 (Unlimited) allows indefinite storage without moisture control. MSL 2 (1 Year) requires moisture control for up to one year. MSL 3 (168 Hours) requires moisture control for up to 168 hours. For high-reliability applications, MSL 1 components are preferred. The TSV358IPT, NCS20082DTBR2G, NCV20082DTBR2G, and MCP6L02T-E/MS all carry MSL 1 rating.
Q: Can the AZV832MMTR-G1 replace the TSV358IPT in automotive applications?
A: No. The AZV832MMTR-G1 operates only to 85°C maximum temperature, whereas the TSV358IPT operates to 125°C. Additionally, the AZV832MMTR-G1 carries MSL 3 rating, requiring strict moisture control. For automotive applications requiring extended temperature operation and AEC-Q100 qualification, the AZV832MMTR-G1 is not suitable.
Q: What are the key electrical differences between the TSV358IPT and its substitutes?
A: The primary differences are input bias current (TSV358IPT: 70 nA; substitutes: 0.2-2 pA), output current per channel (TSV358IPT: 80 mA; substitutes: 15-185 mA), and supply current consumption (TSV358IPT: 500 µA; substitutes: 48-150 µA). The TSV358IPT provides higher output current capability, while most substitutes offer lower input bias current and reduced power consumption. Select substitutes based on your circuit's specific requirements for output current, input impedance, and power budget.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. All substitute parts listed (NCS20082DTBR2G, NCV20082DTBR2G, OPA2313IDGKR, MCP6L02T-E/MS, and AZV832MMTR-G1) are RoHS3 compliant, matching the TSV358IPT's compliance status.
